Is the plot suitable for a narrow house for 5 people?

Hello!

We may possibly have the (rather rare) chance locally in the tendering process to get a well-located plot for us in the new development area (edge, quiet, view of greenery, strategic location for school attendance, affordable...).

I have attached the excerpt of the development plan (no significant slope - along both axes 0.5m).

The problem: We are a family of five with three children. In principle, we could build 2.5 stories (also with a basement if necessary), but the single-family house building window is a 'cut-off semi-detached house' with 12m x 7m.

We need three children's rooms and a study. Preferably small (10m2).

Question: Is this in such a small plot (or building window) even remotely sensible? I ask to prevent us from talking ourselves into something. The location is very good for us (children could stay at their schools). However, I have never seen a comparably narrow and tall single-family house in a new development. The only thing I found to form an optical gut feeling would be the citiline 2 from Allkauf Haus (and that is longer).

Thank you very much!


Development plan/restrictions (see photo)
Plot size: 350m2
Slope: No. 0.5m slope short axis, 0.5m slope long axis
Floor area ratio: 0.35
Floor space index: 0.7
Building window, building line, and boundary: see plan, 12m x 7m.

Number of stories: should be 2.5 or 2 with basement
Roof type: gable (or hip) 30-42 degrees (15-20 degrees)

Orientation: NW->SE
Maximum heights/limits: 154/160


Builders’ requirements
Style, roof type, building type: city villa, gable
Basement, stories: living basement & attic conversion?
Number of people, age: 5 (45, 45, 13, 11, 10)
Space requirements on ground floor, upper floor: 70, 70 (+more for 3 children's rooms in attic / basement)
Office: family use or home office? 1 office.

...our budget is probably relevant: 850,000€

Land: 185,000€
For the house (all incl.) remaining: 665,000

For a house with the desired requirements, that is definitely enough. On a smaller plot, we used to have 4 bedrooms/children's rooms/offices in a semi-detached house (on just over 200sqm of land). Two full floors + attic conversion. Don’t look at house providers, go to the architect.

Hello , welcome to the forum, I would go and ask at the building authority whether a single semi-detached house as drawn is approved to be connected to the garage. If yes, then there are enough functional floor plans on 12x7m.

PS, in 2 years you will probably realistically be in the house, by then the children will only be in the house for a "short" time. For the "short" time, plan a multifunctional room with subsequent use only for you.

For 10 years, until the first child moves out, I would build based on the current needs and when the third child moves out, sell the house again and get a house suitable for the next phase of life.
