Here is the construction service description for people who do not want to look at every single picture but still want to enjoy the fun:
1. Architect services & building permit
Planning & preparation of building permit
Our planning department takes care of the approval and construction organization necessary for your building project. We ensure that the right trade starts work on your construction site at the right time.
Our employees select and contract the appropriate companies from a network of proven construction partners and craftsmen.
As soon as you inform us that you would like to start planning and preparing your building permit documents, an employee of our planning office will contact you to discuss and plan your building project in detail. An architect plans your house based on our existing designs (model houses) or freely and individually according to your wishes and ideas by agreement.
To complete your building permit application, we require the following documents for your building plot:
• Preliminary location plan (lx) with boundary lengths and height points without project entry, including current cadastral map excerpt as PDF and DFX files
• Official qualified location plans in quintuplicate with registration of HN heights and boundary lengths
• Official regulations and certifications relevant to the construction of your house (e.g., water protection zone, noise protection requirements, etc.)
• Proof of secured infrastructure for your building plot for water, wastewater, and electricity
• Proof of building regulations according to a development plan or if building according to §34 is intended
For your surveying services, we can gladly obtain a complete offer including the setting-out framework; you will commission this independently. The billing of surveying services is done directly with you as the commissioning client.
We prepare your submission planning in fivefold copies, all drawings are presented at a scale of 1:100, including floor plans, elevations, and section drawings.
The calculation of the enclosed volume is carried out according to DIN as well as the calculation of living and usable areas, which are part of the submission planning.
The plotting of your building is done by the surveyor you commission. You, as the builder, must provide us with the location plan with the drawn-in building for compiling your submission planning.
We arrange for your thermal insulation certificate for the newly planned project to be calculated and issued after completion of the submission documents and according to the applicable energy saving ordinance (EnEV). The same applies to the static and structural planning.
We only prepare a soundproofing certificate or tree felling application if it is required by authorities and you commission us for it at a cost.
Furthermore, we also prepare the planning documents for your financing and, if necessary, for subsidies (e.g., KfW).
As soon as your building permit documents are completed, we send them to you. The signed application documents are forwarded to the responsible building authority.
As the builder, you are responsible for applying for, bringing in, and installing your house connections as well as any necessary traffic regulations, such as road closures and the erection and maintenance of traffic lights and signage. The resulting costs, including any official fees, must be borne by the builders. Your house building consultant will also be pleased to assist you with any questions that arise.
Measures that go beyond the construction description are not included in the purchase price. These must be individually planned and commissioned separately by you. The planning and construction of your feel-good house is carried out based on the current energy saving ordinance. After completion of the house, you will receive an energy certificate for your residential building from us.
Specification of details
Already at the time of contract signing, you as the builder determine the exterior masonry, the color and material of your roof covering, and whether your house is to be built as a plastered building or with facing brickwork.
After completion of your building permit planning, our contractually bound specialist companies will contact you to apply for necessary permits (e.g., at energy suppliers - electricity; water - wastewater) and to discuss the selection of your fittings. For this purpose, we work with professionally competent fitting centers. Here you can coordinate your special wishes for sanitary fittings, tiles, windows, front door, interior doors, and much more. Your selections from the sampling are incorporated into the planning. Before construction begins, we will conduct a factory plan discussion with you at our premises together with your future construction manager. Details as well as implementations and the prerequisites before the start of construction will be discussed at this time. By then, construction water and construction electricity should be available on site.
2. Construction services
Construction site setup
A comprehensive construction site setup is already included in our scope of services. This includes the installation and cleaning of a construction toilet, erection of scaffolding, proper disposal of construction waste, rubble, and leftover building materials generated by our craftsmen or suppliers during construction (e.g., foil, cardboard, pallets, etc.). To ensure the stability of your house, we carry out a geotechnical investigation on your building plot before construction begins. This is performed by a geotechnical expert commissioned by us. These services are already included in the fixed price. Two static probing tests will be carried out in the area of the new building structure to check stability. Furthermore, we obtain necessary planning information on:
• Stagnant and layered water
• Permissible soil pressure
• Determination of soil parameters
• Determination of the infiltration capacity of the existing soil
The plot to be built on must be such that the required work can be carried out without obstruction.
The plot must be completely cleared of trees, tree stumps, shrubs, rubble, old buildings, etc. The construction site including the driveway (construction road) must be accessible to vehicles up to 40 tons.
Regulations for sidewalk crossings must be observed; the builder is liable in case of damage. If necessary, we will gladly support you with preparatory work and obtain cost offers accordingly. Any required road closures must be applied for and implemented by the client in a timely manner at their own expense.
The excavation pit will be surveyed and angled by your appointed surveyor using a setting-out frame. The fine setting-out including height determination and any approval by the authority must be initiated by you in coordination with your commissioned surveyor in good time. The boundary stones are verified and kept clear by your surveyor.
The construction electricity and water connections must be present on the plot. Billing for construction electricity and construction water is handled directly by the public suppliers to the builder.
If work is carried out on the plinth area, e.g., construction of external facilities (terraces, platforms, eaves pavement), the builder is responsible for re-sealing and securing the earth-contacting areas, whereby the planned outside level for moisture protection must be 35 cm below 0.00.
To keep the residual construction moisture in the house as low as possible after completion, the builder is also asked during the construction phase to ensure the required minimum air exchange by rapid ventilation.
Construction supervision
You will be competently advised and supervised by our house building team from the beginning in all questions before contract conclusion, during the planning and construction phase, until the handover of your new feel-good house. Your construction advisor, planner, and construction manager will accompany you throughout the entire construction phase. Even if there are questions after the handover of the house, the house building team will be happy to assist you.
3. Insurances
The fixed price already includes a construction all-risk insurance and builder's liability insurance for your construction project. These insure the work performed by craftsmen during construction against vandalism, destruction, and theft and protect you from claims by third parties at the construction site and in case of unforeseen events during the construction period.
We further recommend taking out a shell fire insurance, which is the predecessor of building insurance. On request, we offer this free of charge during the construction phase; after handover of the house, it becomes a mandatory paid building insurance for one year.
4. Earthworks
At the start of construction and before excavation of the building pit, you will again visit the site with your construction manager. You will meet the shell contractor and can discuss with him whether the excavated soil is to be stored on the plot or hauled away. If local conditions require removal, cross transport, or disposal, these measures must be commissioned separately by you.
The resulting costs are not included in the calculated fixed price and will be billed directly with you as the client in this case.
Our calculation for earthworks assumes soil class 3-4 according to DIN 18300 as well as topsoil up to 30 cm and soil pressure of 200 kN/m², no groundwater or layered water in the foundation area, an even, slope-free, cleared, and cleaned building plot, and that the excavation soil remains on the plot.
Additional costs may arise with poorer soil conditions, which can only be specified after evaluating the geotechnical report. Should changes be necessary after evaluating the report, we will prepare a corresponding additional cost offer.
Requirements arising from structural proof and local peculiarities, such as deviating soil values * 180 kN/m², special foundations on slopes, rock, groundwater, clay soil, or underpinning as well as water retention, are not included in the base price.
Additional costs also arise from the removal and disposal of excess excavated soil (topsoil) and excavation of contaminated, polluted, or otherwise burdened soil.
Drainage
Before installing the base slab, drainage pipes will be laid from the drainage points on a direct route about 20 cm outside the planned building. The fixed price includes the entire piping for wastewater within the building structure. The necessary excavation of the pipe trench and all fittings are already included in the fixed price.
5. Foundations & base slab
Your solid house will stand on secure, continuous frost skirts including the base slab. According to static requirements, a base slab at least 20 cm thick made of reinforced cast-in-place or steel fiber concrete (max. steel mesh to Q 257 A) will be constructed.
For frost protection, under the base slab (for houses without a basement), a 15 cm thick full-surface cushion of gravel-sand mixture or recycled material will be installed and mechanically compacted. A separating layer is properly and skillfully laid on this clean layer.
The surrounding frost skirts are constructed unreinforced to a depth of 80 cm; the excavated material is stored sideways on the building plot. The frost skirts are filled with concrete of quality class C16/20 and (for houses without basements) concreted against the earth.
An all-around potential equalization with connection flag is installed in the frost skirts according to VDE regulations.
The thickness of the base slab depends on the static calculation but is at least 20 cm and is made of concrete quality class C25/30. To avoid cold or thermal bridges, your base slab receives a 6 cm Styrodur insulation with a thermal conductivity class (WLG) 035 all around.
Depending on the project, five empty conduits (KG pipes) are laid in the base slab: heating, water-wastewater, electricity, and telephone.
These empty conduits are planned on the shortest path at the outer edge of the base slab at the prescribed depths.
Note: If your responsible suppliers require different regulations or provisions, e.g., for single or multi-line entry, these must be handed over independently by the client to the contractor before the start of construction. The costs for additional requirements are borne by the client.
6. Masonry & concrete works
Exterior walls/interior walls
Walls are protected against rising damp by horizontal barriers. The base slab or foundation slab receives bitumen waterproofing above. The waterproofing of the base of the masonry is carried out according to DIN 18195. The masonry is laid using the adhesive method according to the manufacturer's instructions.
We place great value on monolithic construction, so you can choose from several variants for your exterior wall construction:
Variant 1: single-layer = 36.5 cm T10 hollow brick (without insulation fill)
Variant 2: single-layer = 36.5 cm aerated concrete block PP 2/04
Variant 3: three-layer = as clinker facade (at additional cost if contractually agreed)
Load-bearing and non-load-bearing interior walls are made from planar hollow bricks or aerated concrete depending on the exterior wall construction chosen according to static requirements (thickness 11.5 cm, 17.5 cm, or 24 cm) in town villas on the ground & upper floors as well as bungalows and one-and-a-half-story houses on the ground floor (excluding installation walls).
For one-and-a-half-story houses or finished attic rooms in bungalow types, all non-load-bearing interior walls in the attic are constructed as stud wall constructions (thickness 10 cm) with single-layer plasterboard and internal insulation.
On request and for an additional charge, interior walls in the attic can also be executed solidly from PLAN hollow bricks or aerated concrete (as far as technically & statically possible). All interior walls are made in Q2 quality ready for wallpapering.
The finished room height depends on the floor construction.
Clear room heights for one-and-a-half-story houses & town villas are approx. 2.57 m on the ground floor and approx. 2.52 m in the attic or upper floor, taking into account the floor insulation construction. Bungalow buildings have a constructive clear room height of approx. 2.52 m.
When building a semi-detached or terraced house, party walls are constructed according to static requirements and extend up to the roof covering. The execution of party walls is done in a double-shell construction and corresponds to recognized rules of technology. A sound insulation layer made of mineral wool about 40 mm thick is installed between the masonry shells.
Balconies and bay windows are always agreed as additional equipment depending on size and material.
7. Exterior plaster facade
We pay special attention to quality and visual durability on the exterior facade of your new house.
The exterior masonry is prepared and primed according to recognized rules of technology and applicable manufacturer specifications. Corner protection profiles are fixed and level installed on the outer corners, window and door reveals, and the plinth.
The connection to building elements such as windows and the front door is made with plastic plastering strips (APU - strips). This ensures a durable and professional execution of these building connections.
A single-layer mineral lightweight plaster with a thickness of 15-20 mm is applied as the base coat. The surface is smoothed and roughly troweled. After setting and drying of the base coat, a full-surface reinforcing layer is applied.
The top coat is executed according to the respective exterior masonry as a = mineral disc plaster (brick masonry) or b = silicone resin plaster (aerated concrete) with a grain size of 2 mm and then painted with a leveling coat in a light color (pastel tones). You can choose light shades with a brightness reference value of 70. This leveling coat protects the exterior plaster from environmental influences, as it is factory-equipped with fungicide and algicide and thus protects against mold, algae, and moss infestation under normal weather conditions.
A continuous plinth with a height of 30 - 50 cm above existing ground level is executed. The top coat is applied with gauze, reinforcing mortar, and colored stone plaster. Coating of reinforced concrete columns is not included in the scope of services.
8. Clinker facade (if contractually agreed)
A clinker facade is considered a special request and is produced according to the defined wall construction of the current version of the energy saving ordinance. We will gladly offer you a clinker or facing brick facade at an additional cost.
9. Interior plaster
All masonry interior wall surfaces on the ground floor and finished upper/final attic floors receive a smooth plaster coat with all necessary corner protection strips. The plaster surface corresponds to the standard quality Q2 recommended by the Federal Association of Gypsum Industry e.V. Plaster surfaces of quality level 2 meet the usual requirements for wall and ceiling surfaces and are particularly suitable for medium-weight wallpapers. This interior plaster is suitable for wet rooms.
For an additional charge, a lime-cement plaster can be agreed upon for all interior rooms on the ground, attic, or upper floors before construction begins.
10. Floor slabs
The floor slabs above the ground floor in houses with finished or prepped attic floors (one-and-a-half-story houses & town villas) are installed as precast reinforced concrete slabs according to static requirements. The ceilings over the upper floors, as well as in bungalow houses the ceilings above the ground floor and the ceilings above conservatories, extensions, and bay windows can, depending on requirements, be executed as a wooden construction in connection with the roof construction.
Accordingly, mineral insulation with an underlying vapor barrier is installed between the wooden rafters according to the heat insulation certificate calculation.
The ceilings are finished at the bottom with single-layer plasterboard, 12.5 mm thick, and spackled (Q2 standard - wallpaper-ready). The attic is not developed.
The joints of the reinforced concrete ceilings are spackled smoothly on the underside to wallpaper quality (Q2 standard - wallpaper-ready).
11. Roof construction & roof covering
The roof structure is carpenter-style as a purlin roof with a 45° roof pitch or as a truss construction (timber frame truss) with a 24° roof pitch. It consists of softwood GKII as solid wood roof trusses, calculated, manufactured, and delivered by a certified specialized wood construction company. Only approved environmentally friendly PCP-free wood preservatives according to DIN 68800 are used during the assembly and erection of the roof truss.
For one-and-a-half-story houses, the roof eaves will be executed with an overhang at the eaves side of at least 50 cm up to 70 cm and on the verge (gable side) 20 cm to 30 cm depending on the house type. In houses with truss construction, e.g., bungalows and town villas, the roof eaves are executed all around with 50 cm.
The visible overhang is built with planed tongue-and-groove boards as a roof box. Wood protection and painting of visible wood are part of the painter’s trade and thus the builder’s own services. We will gladly prepare an offer if required.
The following roof structure is included in the fixed price for hip, tent, half-hipped, and gable roofs:
• Underlay with a vapor-permeable underlay membrane
• Counter battens impregnated with wedge battens
• Roof battens impregnated
• Roof covering with clay roof tiles (e.g., Nelskamp, Röben building materials, BRAAS, or equivalent)
• Fittings for covering verge, ridge & hip
All necessary fittings for verge and ridge tiles are included in the fixed price. Depending on the house plan, one or two sanitary ventilation tiles are included in the house price. Ridges and hips are installed without mortar.
Roof covering/clay roof tiles
• You choose your roof covering from engobed or noble engobed clay roof tiles. For this, you can select roof tiles from manufacturers such as Nelskamp, Roben, BRAAS, or equivalents, e.g., Nelskamp’s FÜ81/2 in the following color variants: 1. matte black, 2. black noble engobe, 3. copper red, or 4. slate gray.
Other model variants and an antenna outlet tile are available at an additional cost.
The gable closure is executed with verge tiles. For bungalow style, nail board trusses are used, whereby an upper floor expansion is not possible or only realizable with additional effort.
Roof drainage is done with half-round, hung titanium zinc sheet gutters. All fittings and downpipes are included in the fixed price. Downpipes are laid to the top edge of the terrain. Sheet metal works are carried out in titanium zinc sheet metal.
As far as roof windows have been agreed or are included in the base price, we supply these standard in the GGL pivot version by the manufacturer: Velux. These are professionally installed between the rafters according to the planning and later insulated and clad from the inside.
Due to various geographical and geological conditions, Germany is divided into wind, snow, and earthquake zones.
As a basis for calculating your roof statics, we assume wind zones 1 and 2, earthquake zone 0, and snow loads up to 1.6 kN/m². This corresponds to the norms and classes in central Germany. A wind suction safety certificate will be prepared.
12. Attic conversion & drywall construction
In house types with upper or attic floors, thermal insulation is laid in the roof slopes as well as in the horizontal collar beam under the attic. The formation of the attic is done as a cold roof.
Thermal insulation in your attic space is laid as flame-retardant and provided with a vapor barrier according to the current energy saving ordinance requirements in the rafter and collar beam areas. In bungalows, it is executed in the ceiling joist area.
The spaces between rafters and collar beams are fully filled with mineral insulation depending on the project according to the current heat protection calculation. Usually, mineral insulation with a thickness of 200 mm or 240 mm and a thermal conductivity class of 035 is used. The vapor barrier is professionally laid as an approved foil; all joints, penetrations, and connections are air-tightly sealed with appropriate adhesive tapes.
The sheathing is done with 12.5 mm gypsum board on a substructure.
In house types without a finished attic, the insulation is laid horizontally in the wooden beam ceiling or in the lower chord of the roof construction up to the outer edge of the ring beam. Here too, the energy saving ordinance regulates the thickness of thermal insulation. The attic is executed as a cold roof.
All joints of the sheathing are properly spackled in several work steps and produced ready for wallpapering in Q2.
The permanent elastic production of building connections such as connection joints between wall and wall or wall and ceiling must be made of acrylic and is part of the painter’s work and thus the builder’s own services.
Required installation walls and boxed-in elements are manufactured in drywall construction. The pre-walls shown in the contract drawings or separately agreed additional services are included in the price. If additional square meters of drywall are required due to changes in the bathroom layout, these services are to be billed directly with the drywall contractor on site.
A three-part insulated attic access hatch is installed as standard in all houses.
13. Staircases
Solid wood staircase
The staircase to the upper or finished attic floor is executed as a handcrafted solid wood staircase in open construction. The treads are bolted on the wall side with sound decoupling, giving you high load capacity and walking safety. Your interior staircase is made and installed from wood (beech parquet glued).
It consists of treads as well as a rising internal stringer balustrade with round stainless steel balusters, a handrail, and balustrade support posts. The staircase is handed over treated and sealed.
An insulated folding attic staircase with a three-part folding function in the size: 60 x 120 cm is delivered and installed. The installation of this staircase takes place as part of the drywall work in the hallway area and depends on the position of the truss construction and static calculations.
For an additional charge, we can gladly offer you precast concrete staircases, which are delivered and mounted with the corresponding dimensions for the entry and exit as well as in the prescribed riser dimension. The underside (front sides) and risers are delivered smooth but not as exposed concrete in terms of surface definition. Spackling of any offsets and inclusions is part of the painter’s work and is not included in the delivery and installation scope.
For the surfaces of the treads, there are various final coatings, the same applies to the stair railing, which must be coordinated with us before ordering.
14. Windows, terrace doors & front door
Windows and window doors (floor-to-ceiling window elements)
All window elements and terrace doors consist of white 6-chamber plastic profiles with internal galvanized steel profiles, two sealings, triple glazing with a Ug value of 0.6, and burglar-resistant mushroom head locking (basic security).
Furthermore, the windows & terrace elements comply with sound insulation class 2, corresponding to a sound attenuation value of approx. 34 dB.
Single-leaf windows & terrace elements are equipped with tilt-and-turn function and a handle olive. Double-leaf windows & terrace elements are executed as a French door without a center post with a handle olive. Every terrace door receives a handle shell and catch device; at no extra charge, double-leaf windows & terrace doors can also be equipped with tilt-and-turn - tilt-and-turn function (thus with center post).
Fixed glazing is glazed in the frame. The dimensions of the elements result from the contract drawings.
Fall protection devices, e.g., for floor-to-ceiling window elements in the upper or attic floors, are installed below with fixed glazing and a TRAV element (horizontal bar) as fall-safe glazing.
For an extra charge, we can also offer French balcony railings made of hot-dip galvanized metal. Muntins in the windows as well as higher security levels (RC 1, RC 2 N, RC 2) and safety glass P4A or P5A are available at an extra charge.
Windows with fixed safety glazing
For windows with fixed lower parts and safety glazing as well as windows completely made of safety glazing, the Ug value of the triple safety glazing changes to a Ug value of 0.9 to 1.1.
Rectangular deviating window base surfaces, window muntins, window shutters, roof windows, bay windows, conservatories, etc., are, if not included in the building contract, to be ordered separately as additional equipment.
Front door system
A front door system with RAL-tested door element with high-quality 6-chamber plastic profile and reinforcement profiles made of galvanized steel and an installation depth of 86 mm in white is installed.
Several front door variants in white with flush door wings, with smooth paneling, or glazed sections with double insulating safety glass are available as standard.
Installation is carried out according to DIN and the requirements of the energy saving ordinance. The front door will be air-tight and wind-tight sealed and sealed inside with airtight and outside with sealing tape (airtight inside and diffusion-open outside). The joints between frame and masonry are closed with high-quality insulation material to ensure an absolutely tight connection.
In partially or fully finished attic floors, manually operated plastic roller shutters are installed on all windows & terrace doors. They are mounted as so-called overlay roller shutters on the window elements and assembled together. Your thermally insulated roller shutter boxes are plastered over from outside and inside and are not visible. The inspection is carried out from inside underneath in the window reveal.
You can choose from the following color variants: gray, beige, or white.
Operation of the roller shutter is by a white plastic belt roller, which is attached inside to the window frame.
For an extra charge, we also offer electrically operated roller shutter motors and will prepare an offer accordingly.
Your front door, secondary doors, e.g., in the utility room, glass bands and fixed glazing, e.g., in the staircase, roof windows, and full glass bay window elements do not have roller shutters.
16. Window sills
15.1 Interior window sills
The interior window sills consist of Jura marble or agglomerated marble in the color variants Breccia Aurora, Perlato Appia, or Micro Carra white and have a thickness of approx. 2 cm. The selection is made by the builder according to the sample templates. Window sills in the bathroom and guest WC are tiled. The interior window sills protrude approx. 5 cm into the room. The connection between window sill and window profile is sealed with an elastic joint, e.g., transparent color.
15.2 Exterior window sills for plaster facade
The exterior window sills for plaster facades have a thickness of approx. 2 cm and consist of polished granite in the color variants Rosa-Beta or Serizzo. They have a lower drip edge, two upper drainage grooves, and one bevel. The connection between window sill and window profile is elastically and transparently sealed as with the interior window sills.
15.3 Exterior window sills for facing brick facade
The exterior window sills for facing brick or clinker facades are made as brick soldier courses from facing bricks or clinker stones.
For all floor-to-ceiling window elements, side entrance doors, and front doors on the ground floor, no exterior window sills are installed considering later terrace and path construction. The covers will be properly installed and sealed at a later date by the builders or the civil engineering company (pavers) in the material of the terrace and path construction.
On request, we can offer additional covers or exterior window sills at extra cost.
17. Electrical installation
Our construction partners carry out all electrical installations according to the applicable VDE regulations. Installation in a house starts with the floor slab at the house connection (utility room or HAR), provided it is inside the house (otherwise at the exterior wall).
A meter cabinet according to the utility company’s regulations is installed with the corresponding fuse fittings in the house connection room (utility room/HAR). Your heating system, electric stove, and washing machine receive separate protected circuits. According to your wishes, sockets for the washing machine and tumble dryer are installed in the house.
We want you to live comfortably in your feel-good house, so the number of switches, sockets, lines, and other connections are generously dimensioned. The equipment of all living rooms is done with white flat switches and sockets according to our sample template (e.g., brands Berker S1, Busch Jäger, or Jung).
The heating system is fully wired including the outdoor temperature sensor and connected to the power circuit. Smoke detectors are installed independently of the power supply with batteries.
