Hello everyone,

my husband and I would like to build a second house on my parents' property. The property with 760 sqm still offers enough space to build here with a small garden. We have obtained preliminary approval from the building authority for a 1.5-story single-family house with a gable roof (that only took 6 months…). To avoid using up the entire garden, we plan to "dock" part of the house (currently planned as the utility room) on the ground floor to my parents' house. Unfortunately, we don’t know if this is possible from a fire protection standpoint and whether we need to maintain any other distances? If possible, we would like to keep the entire property registered under my parents' name and not split it (it is a leasehold property from the church with more than 60 years remaining; the church will only provide a statement once we submit a plan/idea of what we want to do – logical).

I hope I have included all important data/basic ideas. Otherwise, I will be happy to provide them later. I look forward to experiences, suggestions, and tips!

Development plan/restrictions
Size of the property -->759 sqm in total (“our part” about half)
Slope -->No
Site coverage ratio -->0.4
Floor area ratio -->0.5
Building window, building line, and boundary -->The preliminary planning approval states that a minimum distance of 3m to public traffic areas must be maintained, the other stipulations of the development plan must be complied with, and the necessary exemption of the buildable property area will be granted in the building permit process.
Edge development -->Yes, desired carport and fence directly on the property boundary
Number of parking spaces -->1 parking space
Number of floors -->1.5 floors
Roof shape -->Gable roof
Maximum heights/limitations -->One side should be a maximum of 9m long, so we don’t become wider than the existing house
Further specifications -->The “problematic” part is the beveled corner of the property; to use the property area as efficiently as possible (3m to the boundary) we would also bevel the house. In addition, the parents' existing house must be taken into account (directly attached? Minimum distance? Fire protection?)

Requirements of the builders
Style, roof shape, building type -->Gable roof, otherwise fairly open
Basement, floors -->1.5 floors, no basement desired (high groundwater level!)
Number of people, age -->Family with one child, planning for two
Space requirements on ground and upper floor -->Ground floor: kitchen + dining area, separate living room, utility room, office which should later serve as a bedroom, bathroom with shower (the ground floor should be planned in a way that it can be used as an autonomous apartment in old age). Upper floor: 2 children's rooms, bedroom (preferably with a small dressing area/room), bathroom
Office: family use or home office? -->A home office is necessary
Overnight guests per year -->None
Open or closed architecture -->Rather closed
Conservative or modern construction
Open kitchen, kitchen island -->Kitchen island not necessarily, but an outstanding counter would be nice
Number of dining seats -->Four
Fireplace -->No
Music/stereo wall -->Normal living room wall
Balcony, roof terrace -->No
Garage, carport -->Carport
Utility garden, greenhouse -->Maybe a small greenhouse later
Further wishes/particularities/daily routine, also reasons why this or that should or shouldn’t be -->Oh, there are many (e.g., pantry next to kitchen, access from kitchen to garden, utility room as a “dirt lock,” office should not be next to living room due to noise level, no stairway right near the door so that you can enter the house properly, etc.)

House design
Who designed the plan -->Do-it-yourself (Roomsketcher)
What do you particularly like? Why? -->Use of the beveled house corner as a pantry (I find it difficult otherwise to find a good use for “the corner”), niche for the wardrobe, large utility room (we want to be able to hang laundry in there, or is it too big?)
What do you not like? Why? -->Kitchen perhaps too tight? Too much hallway on the ground floor?
Price estimate according to architect/planner -->Not yet available
Personal price limit for the house, including equipment -->€300,000
Preferred heating technology -->Underfloor heating

Why did the design turn out the way it is? --> See above

What is the most important/basic question about the floor plan summarized in 130 characters?

Is the floor plan sensible for everyday use or do we have major pitfalls that would be annoying daily? Are the rooms “large” enough or maybe even too large? Does it make more sense to build completely detached or do you like the idea of “docking” the utility room on the ground floor to the parents' house?

The left side of the existing building must not have a window. Nowhere.

Not even on the upper floor? Replacing the normal windows and installing fire protection windows is also not allowed?

You can't make a bedroom out of 9m², or only the bed fits in. I find the living room quite "huge," it looks so empty, the dining room is still a separate area (in front of the kitchen), and then the mini office squeezes itself into the corner. I honestly don't believe the budget is enough for the "special shape" with the slanted corner and bay window.

The all-in budget will not be quite enough. I would clarify fire protection, I fear Ypg is right. Mark the rooms with dimensions and always draw the existing or desired furnishings to scale.

Show clearly more of the property (and the location in the neighborhood). When was the parental house built, was an extension or the addition of another floor considered?

In principle, I do not consider attaching a second residential unit directly for fire protection reasons to be impossible, but: "still plenty of lawn area available" is not equivalent to "floor area ratio allows for a second house" even without a development plan. I am still missing various answers (year of construction of the parental house, duration of the leasehold ...).
