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!

For a house with the desired requirements, this is definitely sufficient. On a smaller plot, we previously had 4 bedrooms/children’s rooms/offices in a semi-detached house (on a plot slightly over 200sqm (2153 sq ft)). Two full floors plus attic conversion.

Don’t look at house builders, go to an architect.

Hello @trose69, welcome to the forum,
I would recommend contacting the building authority to check whether a single semi-detached house, connected to the garage as shown, would be approved.
If so, there are plenty of functional floor plans available for a 12m x 7m (39ft x 23ft) space.

PS, realistically you will probably be in the house in 2 years, and by then the children will only be living there for a "short" time.

For this "short" period, plan multifunctional rooms that can later be used exclusively by you.

With 10 years until the first child moves out, I would build according to your current needs and then, when the third child has left, sell the house and get a suitable home for the next stage of life.
