Hello!
We might have a (rather rare) chance locally in the bidding process to secure a well-located plot in a new development area (edge location, quiet, green views, strategic position for school access, affordable...).
I have attached a section of the development plan (no significant slope – only 0.5m (1.6 feet) incline along both axes).
The problem: We are a family of five with three children. In principle, we could build 2.5 stories (possibly with a basement if needed), but the single-family house building footprint is like a "cut-off semi-detached house" measuring 12m by 7m (39 feet by 23 feet).
We need three children’s bedrooms and a study. Preferably small (10m² (108 square feet)).
Question: Is this at all reasonable on such a small plot (or building footprint)? I’m asking to avoid convincing ourselves it works when it might not. The location is very good for us (the children could stay at their current schools). However, I have never seen a comparably narrow and tall single-family house in a new development. The only thing I found to get a rough visual idea was the Citline 2 model from Allkauf Haus (and that one is longer).
Many thanks!

Number of floors: should be 2.5 or 2 with basement
Roof shape: gable (or hip) 30–42° (15–20°)
Orientation: NW to SE
Maximum height limits: 154/160 (presumably centimeters or regulations – please clarify)
Client requirements
Architectural style, roof shape, building type: urban villa, gable roof
Basement, floors: residential basement & attic conversion?
Number of occupants, ages: 5 (45, 45, 13, 11, 10 years)
Space needs on ground and upper floors: 70m² (750 square feet), 70m² (750 square feet) (+ additional space for 3 children's rooms in attic/basement)
Office: family use or home office? 1 office

But a house with that number of rooms should definitely be possible.

If it’s 10 years until the first child moves out, I would build according to the needs NOW and once the third child has moved out, sell the house and get a home that suits the next phase of life.Yes – that’s what we were thinking too. Two and a half floors probably won’t be fully accessible. We are planning for 15 years (in case we still need to cover the time for studies).

Hello @trose69, welcome to the forum,
I would suggest checking with the building authority whether a single semi-detached house as shown, attached to the garage, would be approved.
If yes, then there are plenty of functional floor plans for 12x7m (39x23 feet). Thanks! Yes, we definitely plan to contact them. I can imagine a semi-detached house in a full duplex of this size over three floors. However, I find it difficult to envision this for such a narrow single house footprint with a semi-detached layout. I’m also not sure whether the garage might need to be included under the gable roof – see point 1.5 of the development plan text below.
But: We really should speak with an architect. This option has come up rather suddenly for us.

This also gives me the chance to show the other two plots (light green dots on the left and in the middle).
Right now we are considering whether a larger bungalow with a finished basement (perhaps in the style of a granny flat) would be an option for us. The left plot has a nice, unobstructed garden but can only be built as a single story. In terms of accessibility and possible future rental, that would of course be an advantage.
Regarding the available floor area ratio (FAR): I suppose a loft extension wouldn’t be allowed, right (NRW)?
The middle plot could be built on very traditionally but there is a slope of 0.7 m (27.6 inches) in the garden down to the relatively open street. However, that should definitely be manageable.
Tough decision.

Schorsch_baut30 Sep 2024 11:10I find that rather difficult. Seven rooms spread out on a bungalow footprint? And if the daylight basement only has light wells or courtyards, in my opinion, that results in less valuable living space compared to building upwards. Building higher provides better views and natural light.
