Here is the construction service description for people who do not want to look at every picture individually, but still want to enjoy the fun:
1. Architect services & building application
Planning & preparation of building application
Our planning department takes care of the approval and construction organization necessary for your construction 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 application documents, a member of our planning office will contact you to discuss and plan your construction project in detail. An architect designs your house based on our existing designs (model houses) or, by arrangement, freely and individually according to your wishes and ideas.
To complete your building application, we require the following documents for your building plot:
• Preliminary site plan (lx) with boundary lengths and height points without project entry, including current cadastral excerpt as PDF and DFX file
• Officially certified site plans in five copies with entry of ground level heights and boundary lengths
• Official regulations and certificates relevant to the construction of your house (e.g., water protection zone, noise protection requirements, etc.)
• Proof of secured development of your building plot for water, sewage and electricity
• Proof of building regulations in terms of a development plan or, if construction is to be carried out according to §34
For your surveying services, we can gladly obtain a complete offer including batter frame; the commissioning is done independently by you. The billing of surveying services is handled directly between you as the commissioning client and the surveying company.
We prepare your submission planning in five copies, all drawings are presented at a scale of 1:100, including floor plans, elevations, and section drawings.
The calculation of the enclosed volume, as well as the living and usable areas, is carried out according to DIN standards and is part of the submission planning.
The plotting of your building is carried out by the surveyor you have commissioned. As the client, you must provide us with the site plan including the plotted building for the compilation of your submission planning.
Your thermal insulation certificate for the newly planned construction project will be calculated and issued after completion of the submission documents according to the valid energy saving ordinance (EnEV), the same applies to statics and structural engineering.
We only prepare a noise protection certificate or tree felling application if this becomes legally necessary and you commission us for it at your own cost.
Furthermore, we also prepare planning documents for your financing and for subsidies if required (e.g., KfW).
As soon as your building application documents are completed, we will send them to you. The signed application documents will be forwarded to the responsible building authority.
As the client, you are responsible for applying for, providing, and installing your house connections and any necessary traffic regulations, such as barriers and the erection and maintenance of traffic lights and signage. The resulting costs, including any official fees, are to be borne by the clients. Your house building advisor is also available to assist you with any questions.
Measures that go beyond the construction description are not included in the purchase price. These must be planned individually 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 contract signing, you as the client specify which exterior masonry, color and material your roof covering should have and whether your house should be constructed as a plastered building or with facing brickwork.
After completing your building application planning, our contracted specialized companies will contact you to apply for necessary permits (e.g., from the energy provider – electricity; water-sewage) and to discuss the sampling of your equipment. For this purpose, we cooperate with competent equipment centers. Here you can agree on your special wishes for sanitary, tiles, windows, front door, interior doors, and much more. Your decisions from the sampling will be incorporated into the planning. Before construction begins, we will hold a factory plan discussion with you at our premises together with your future construction manager. Details, executions, and the prerequisites before the start of construction will be discussed again. At this time, construction water and construction electricity should be available on the site.
2. Construction services
Construction site setup
Our service scope includes comprehensive construction site setup. This includes the installation and cleaning of a construction toilet, the erection of scaffolding, professional disposal of construction waste, rubble, and material remnants arising during construction by our craftsmen or suppliers (e.g., films, cardboard, pallets, etc.). To ensure the stability of your house, we carry out a soil investigation on your plot before construction begins. This is conducted by a soil surveyor commissioned by us. These services are already included in the fixed price. Two driving soundings will be carried out in the area of the new building body to check stability. Furthermore, necessary planning information on:
• Stagnant and stratified water
• Allowable soil bearing pressure
• Determination of soil parameters
• Determination of the infiltration capacity of the prevailing soil
The plot to be built on must be accessible so that the required work can be carried out unhindered.
The plot must be completely cleared of trees, stumps, shrubs, rubble, old buildings, etc. The construction site including the access road must be accessible for vehicles up to 40 tons.
Regulations for sidewalk crossings must be observed; the client is liable for damages. If necessary, we are happy to assist you with preparatory work and obtain cost estimates for you. Any required road closures must be applied for and implemented by the client at their own expense in due time.
The excavation pit is staked out according to the batter frame by your instructed surveyor and squared. The fine staking including height determination and any acceptance by authorities must be promptly arranged in coordination with your surveying engineer. Boundary stones are documented and kept clear by your surveyor.
Construction electricity and water connections must be present on the property. Billing for construction electricity and water is settled directly with the public utilities by the client.
If work is carried out on the base area, e.g., construction of your outdoor facilities (terraces, platforms, eaves paving), the client is responsible for ensuring renewed sealing and safeguarding in the areas in contact with the ground, whereby the planned outdoor level for moisture protection must be maintained 35 cm below 0.00.
To keep construction residual moisture as low as possible after house completion, the client is also asked during the construction phase to ensure the required minimum air exchange through shock ventilation.
Construction supervision
You will be competently advised and supported from the beginning of your project by our house building team in all questions before contract conclusion, during the planning and construction phases up to the handover of your new feel-good house. Your construction advisor, planner, and construction manager accompany you throughout the entire construction phase and will be available even after the handover in case you have questions.
3. Insurance
The fixed price already includes builder’s all-risk insurance and builder’s liability insurance for your construction project. This insures the services of craftsmen against vandalism, destruction and theft during construction and protects you from claims by uninvolved third parties and unforeseen events during the construction period.
We also recommend taking out a shell construction fire insurance; this is the precursor to building insurance. On request, we offer this free of charge during the construction phase; after handover, it becomes a mandatory paid building insurance for one year.
4. Earthworks
Before construction begins and before excavation of the foundation pit, you will inspect the site again with your construction manager. You will meet the shell construction contractor and discuss with him whether the excavated soil should be stored on the plot or removed. If local conditions require removal, cross transport or disposal, you must commission these measures separately.
The resulting costs are not included in the fixed price and will be billed directly to you as the client.
Our calculation for earthworks assumes soil class 3-4 according to DIN 18300, topsoil up to 30 cm, soil bearing pressure of 200 kN/m², no groundwater or stratified water in the foundation area, leveled, slope-free, cleared and cleared construction plot, and that excavation material remains on the site.
If soil conditions are worse, additional expenses may arise, which can only be stated after evaluation of the soil report. Should changes become necessary after the report is evaluated, we will provide you with a corresponding additional cost offer.
Not included in the base price are requirements resulting from structural calculations and local special features, e.g., deviating soil values *180 kN/m², special foundations in slopes, rock, groundwater, clay soil or underpinning as well as water management.
Additional costs also arise from removal and disposal of excess soil (topsoil) and excavation of contaminated, polluted, or otherwise affected excavation.
Drainage
Before installing the base slab, drainage pipes from the drainage points are laid directly to about 20 cm outside the planned building. The fixed price includes the entire pipe routing for wastewater within the building body. The necessary trench excavation and all fittings are already included in the fixed price.
5. Foundations & base slab
Your solid house will stand on safe, continuous frost skirts including the base slab. Accordingly, a base slab at least 20 cm thick made of reinforced cast-in-place or steel fiber concrete (max. reinforcement mats up to Q 257 A) will be constructed according to static requirements.
For frost protection beneath the base slab (for houses without cellar), a 15 cm thick full-surface cushion made of gravel-sand mixture or recycled materials is installed and mechanically compacted. A separating layer is properly and professionally laid on this clean layer.
The continuous frost skirts are constructed unreinforced to a depth of 80 cm, the excavation material is stored to the side on the building plot. The frost skirts are backfilled with concrete of strength class C16/20 and (for houses without cellar) concreted against the ground.
A continuous equipotential bonding according to VDE regulations with connection lead is installed in the frost skirts.
The thickness of the base slab depends on the statics but is at least 20 cm and is made of concrete strength class C 25/30. To avoid cold or thermal bridges, your base slab receives a continuous 6 cm Styrodur insulation with a thermal conductivity class (WLG) 035.
Depending on the project, 5 empty conduits (KG pipes) for heating, water-sewage, electricity, and telephone are laid in the base slab.
These pipes are arranged along the shortest route at the outer edge of the base slab at the prescribed depth.
Note: Should your responsible utilities require different specifications or regulations for, for example, single or multi-duct entry, these must be handed over independently by the client to the contractor at 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 moisture by horizontal barriers. The base slab or footing slab is sealed above with a bituminous welding membrane. The wall footing is sealed according to DIN 18195. The masonry is processed using adhesive techniques according to manufacturer guidelines.
We place great emphasis on a monolithic construction; therefore, you can choose from various types of exterior wall constructions:
Variant 1: Single-shell = 36.5 cm T10 hollow brick (without filling)
Variant 2: Single-shell = 36.5 cm aerated concrete plan stone PP 2/04
Variant 3: Triple-shell = with clinker facade (for an additional charge if contractually agreed)
Load-bearing and non-load-bearing interior walls in city villas on ground and upper floors as well as bungalows and one-and-a-half storey houses on the ground floor (except installation walls) are made entirely of plan hollow bricks or aerated concrete depending on the chosen exterior wall construction according to statics (d=11.5 cm, 17.5 cm or 24 cm).
In one-and-a-half storey houses or converted attic floors in bungalow types, all non-load-bearing interior walls in the attic are constructed as stud walls (d=10 cm) with single-layer plasterboard and internal insulation.
On request and for an extra charge, interior walls in the attic can also be constructed as solid walls from PLAN hollow bricks or aerated concrete (as far as technically and statically possible). All interior walls are finished to Q2 quality ready for wallpapering.
Finished room height depends on floor structure.
The clear room heights for one-and-a-half storey houses and city villas are approx. 2.57 m on the ground floor and approx. 2.52 m on the attic or upper floor, taking into account the floor insulation construction. Bungalows have a clear room height of approx. 2.52 m due to construction.
When building semi-detached or terraced houses, the party walls are built according to static requirements and carried up to the roofing membrane. The party walls are executed as double-shell constructions and conform to generally accepted technical rules. Between the masonry shells, a soundproofing panel made of mineral wool approx. 40 mm thick is installed.
Balconies and bay windows must always be agreed upon as extras depending on size and material.
7. Exterior plaster facade
We place special emphasis on quality and optical durability for the exterior facade of your new house.
The exterior masonry is prepared and primed according to recognized technical rules and the manufacturer’s specifications. At the outer corners, window and door reveals, as well as the base, corner protection profiles are attached and worked in plumb and level.
Connections to building elements such as windows and front doors are made with plastic plaster strips (APU strip). This ensures a durable and professional execution of these building connections.
A single-layer mineral light plaster with a thickness of 15-20 mm is applied as the base coat. The surface is smoothed and roughly scratched. After setting and drying of the base plaster, a full-surface reinforcing layer is applied.
The topcoat plaster is applied 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 an even coat in a light color (pastel tones). You can choose light color tones with a brightness reference value of 70. This even coat protects the exterior plaster from environmental influences because it is equipped with fungicide and algicide factory-applied and thus protects against fungal, algal, and moss infestation under normal weather conditions.
A continuous base with a height of 30-50 cm above existing terrain level is executed. The top coating is done 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 counts as a special request and is manufactured according to the defined wall structure and the current version of the energy saving ordinance. For an additional charge, we gladly offer a clinker or facing brick facade.
9. Interior plaster
All masonry interior wall surfaces on the ground floor and finished upper/attic floors receive a smoothly rubbed gypsum plaster with all necessary corner protection rails. The plaster surface corresponds to the standard quality Q2 recommended by the Federal Association of the 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 wallpaper. This interior plaster is suitable for wet rooms.
For an additional charge, a lime-cement plaster for all interior rooms on ground, attic, or upper floors can be agreed upon before construction begins.
10. Floor slabs
The floor slabs above the ground floor are installed as precast reinforced concrete filigree slabs according to static requirements in houses with finished or prepared attic rooms (one-and-a-half storey & city villas). The ceilings above 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 be constructed as wooden structures connected to the roof structure as required.
Accordingly, mineral insulation with vapor barrier on the underside is installed between the wooden rafters based on the thermal insulation calculation.
The ceiling is clad on the underside with 12.5 mm thick single-layer plasterboards and spackled (Q2 standard - ready for wallpapering). The attic is not finished.
The joints of the reinforced concrete slabs on the underside are spackled ready for wallpapering (Q2 standard).
11. Roof construction & roof covering
The roof construction is carried out as a carpenter-style purlin roof with 45* roof pitch or as a truss construction (timber frame truss) with 24* roof pitch. It consists of coniferous softwood GKII as solid wood roof truss calculated, manufactured, and delivered by a certified special carpentry company for wood constructions. Only approved, environmentally friendly PCP-free wood preservatives according to DIN 68800 are used during assembly and erection of the roof truss.
For one-and-a-half-storey houses, the eaves overhang is at least 50 to 70 cm on the eaves side and 20 to 30 cm on the gable side depending on the house type. For houses with truss construction, e.g., bungalows and city villas, the roof overhang is continuous 50 cm.
The visible overhang is constructed with planed tongue and groove boards as a roof box. Wood protection and painting of visible wood are the client’s own painting work. We are happy to provide you with an offer if required.
The following roof structure is included at a fixed price for hip, tent, half-hip, and gable roofs:
• Underlay with vapor-permeable underlayment membrane
• Counter battens impregnated with wedge battens
• Battens impregnated
• Roof covering with clay roof tiles (e.g., Nelskamp, Röben-Bau materials, BRAAS or equivalent)
• Mouldings for covering eaves, ridge & hip
All required mouldings for eaves and ridge tiles are included in the fixed price. Depending on the house plan, one to two sanitary ventilation tiles are included in the house price. The 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. Tiles from manufacturers such as Nelskamp, Röben, BRAAS or equivalent are available, e.g., the FÜ81/2 from Nelskamp in the following colors: 1. matte black, 2. black noble engobe, 3. copper red, or 4. slate gray.
Other model variants as well as an antenna outlet tile are possible for an additional charge.
The gable end is finished with verge tiles. Bungalow style uses nail board trusses, whereby expansion of the upper floor is not possible or only possible with additional effort.
Roof drainage is provided by 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. Plumbing work is done in titanium zinc sheet.
If roof windows have been agreed or are included in the base price, we install them as standard in the GGL pivot design from the manufacturer: Velux. These are properly installed according to planning between the rafters and later insulated and clad from the inside.
Due to various geographic and geological conditions, Germany is divided into wind, snow, and earthquake zones.
For the calculation of 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 standards and classes in central Germany. A wind suction proof certificate is prepared.
12. Attic conversion & drywall
In house types with upper or attic floors, thermal insulation is installed in the roof slopes and in the horizontal collar beam under the attic. The formation of the attic is designed as a cold roof.
Thermal insulation in your roof room is laid as flame-retardant and vapor barrier-equipped insulation according to the requirements of the current energy saving ordinance in the rafter and collar beam level. For bungalows, the insulation is done in the ceiling joist level.
The spaces between rafters and collar beams are completely filled with mineral thermal insulation according to the current thermal insulation calculation, usually with mineral insulation 200 mm or 240 mm thick and with a WLG of 035. The vapor barrier is installed as an approved foil; all joints, penetrations, and connections are sealed airtight with corresponding adhesive tapes.
Cladding is done with 12.5 mm thick gypsum boards on a substructure.
For house types without a finished attic, the insulation is installed horizontally in the wooden ceiling beam or the bottom chord of the roof structure up to the outer edge of the ring beam. The energy saving ordinance also regulates the thickness of insulation here. The attic is realized as a cold roof.
All joints in the cladding are properly spackled in several working steps and prepared for wallpapering in Q2 quality. Elastic seam seals such as wall, wall-ceiling connection joints are to be made with acrylic by the painting trade and are thus the client’s own provision.
Required installation walls and boxing are constructed in drywall. The pre-walls shown in the contract drawings or agreed as separate services are included in the price. If additional square meters of drywall arise due to changes in bathroom layout, these services are billed directly with the drywall contractor on site.
In all houses, a three-part thermal insulated folding attic ladder is installed as standard.
13. Stairs
Solid wood staircase
The stairs to the upper or finished attic floor are executed as a handcrafted solid wood staircase in open design. The treads are fastened to the wall side with sound decoupling bolts, providing high load capacity and walking safety. Your interior stairs are made of wood (beech parquet glued) and installed.
It consists of treads and a rising inner stringer with a railing of round stainless steel balusters, a handrail, and railing posts. The staircase is delivered finished and sealed.
A thermally insulated three-part folding attic ladder measuring 60 x 120 cm is supplied and installed to the attic. The installation is part of drywall work in the hallway and depends on the location of the truss construction and static calculations.
For an extra charge, we can offer precast concrete stairs, delivered and installed with the appropriate dimensions for entry and exit as well as the prescribed riser size. The underside (front sides) and risers are delivered smooth but not as exposed concrete in terms of surface definition. Filling joints and inclusions is part of painting work and not included in delivery and installation.
There are various finishes for the tread surfaces and for the stair railing, which must be coordinated with us in advance.
14. Windows, patio doors & front door
Windows and window doors (floor-to-ceiling elements)
All window elements and patio doors consist of white 6-chamber PVC profiles with internal galvanized steel profiles, two sealing lips, triple glazing with a Ug value of 0.6, and burglar-resistant mushroom head locks (basic security).
Furthermore, windows and patio elements correspond to sound insulation class 2, which means a sound insulation value of approx. 34 dB.
Single-leaf windows and patio elements are equipped with tilt-and-turn function and a handle olive. Double-leaf windows and patio doors are executed as French doors without mullion with a handle olive. Each patio door receives a handle shell and catch device; without extra charge, double-leaf windows and patio doors can also be equipped with tilt-turn/tilt-turn function (with mullion).
Fixed glazing is glazed in the frame. Dimensions of elements derive from contract drawings.
Fall protection is installed, for example, on floor-to-ceiling window elements on upper or attic floors below with fixed glazing and TRAV elements (transom bars) as fall-proof glazing.
For an additional charge, we also offer French balcony railings made of hot-dip galvanized metal. Window muntins and higher security classes (RC 1, RC 2N, RC 2) and safety glass P4A or P5A are available for an additional charge.
Windows with fixed safety glazing
For windows with fixed lower parts and safety glazing, as well as windows entirely made of safety glass, the Ug value of the triple safety glazing changes to 0.9 to 1.1.
Rectangular non-standard window base areas, window muntins, shutters, roof windows, bay windows, conservatories, etc., if not included in the building contract, must be ordered separately as extra equipment.
Front door system
A front door system with RAL-certified door element with high-quality 6-chamber PVC profile and reinforcement profiles made of galvanized steel and an installation depth of 86 mm in white is installed.
Standard options include several front door variants in white with flush door leaf, smooth filling or light openings with double insulating glazing made of safety glass.
Installation is according to DIN and energy saving ordinance requirements. The front door is sealed airtight against drafts and wind, with interior airtight sealing and exterior sealing tape (interior airtight and exterior vapor permeable). Gaps between frame and masonry are closed with high-quality insulation material to ensure a completely tight connection.
In created or expanded attic floors, manually operated plastic roller shutters are installed on all windows and patio doors. These are so-called overlay roller shutters mounted on the window element and installed together. Their thermally insulated roller shutter boxes are plastered from the outside and inside and are not visible. Inspection is from the inside below in the window reveal.
You can choose from the following color variants: gray, beige, or white.
Operation of the roller shutter is via a white plastic strap roller mounted inside on the window frame.
For an additional charge, we also offer electrically operated roller shutter motors; we will gladly provide you with an offer.
Your front door, side doors, e.g., in the utility room, light bands and fixed glazing, e.g., in the stairwell, roof windows, and full glass bay windows do not receive roller shutters.
16. Window sills
15.1 Interior window sills
The interior window sills are made 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. Selection is made by the client according to sample template. Window sills in bathrooms and guest WCs are tiled. The window sills protrude about 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 with plaster facade
The exterior window sills on a plaster facade have a thickness of approx. 2 cm and are made of polished granite in the colors Rosa-Beta or Serizzo. They have a lower drip edge, two upper drainage grooves, and a chamfer. The connection between window sill and window profile is sealed elastically transparent as with the interior window sills.
15.3 Exterior window sills with facing brick facade
The exterior window sills on a facing or clinker facade are created as clinker roll layers made of facing or clinker bricks.
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 coverings are professionally installed and sealed at a later date by the clients or the civil engineering company (pavers) in the material of the terrace and path construction.
On request, we can offer additional coverings or exterior window sills for an extra charge.
17. Electrical installation
Our construction partners carry out all electrical installations according to the applicable VDE regulations. Installation starts in a house with the base slab from the house connection (utility room or HAR), provided it is inside the house (otherwise from the outside wall).
A meter cabinet according to EVU regulations is installed with the corresponding protective devices in the house connection room (utility room / HAR). Your heating system, electric stove, and washing machine each receive a separate fused circuit. On your request, a socket for the washing machine and dryer will be installed in the house.
We want you to live comfortably in your feel-good house; therefore, the number of switches, sockets, cables, and other connections is generously dimensioned. All living rooms are equipped with white flat switches and sockets according to our sample template (e.g., Berker S1, Busch Jäger, or Jung).
The heating system including the outdoor temperature sensor is completely wired and connected to the power circuit. Smoke detectors are installed battery-operated and independent of the grid.
