ᐅ Is this plot suitable for a narrow house for 5 people?

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!

7 x 12 is not narrow at all. You can easily get over 160 square meters (1,722 square feet) of living space.

I’m glad to hear that. I had calculated 12 * 7 * 2 * 0.85 = 143 square meters (1,538 square feet) of interior space for two floors. We would still need a finished attic—or a partially finished basement—for three children's bedrooms plus a study.

As I said, I hardly know anything comparable off the shelf (meaning the usual general contractors you find online). But we are still in the early planning phase.

I consider that rather difficult. Seven rooms spread out over a bungalow-sized area? And if the basement living space only has light wells or courtyards, then in my view, that’s a lower-quality living area compared to building narrow and tall. With a taller building, you get views and natural light.

Yes... the idea just came to us as well. Let’s put it this way: We live in a university town. You could even rent out places without windows. (Just kidding. I don’t really think that would work either).

By the way, I was thinking of something along these lines (as a floor plan inspiration, not the general contractor’s house itself): TuC Bungalow 131 (not sure if links are desired).

I would make the living room a bit smaller and move the utility room to the basement. Then the basement could house a large office, utility/technical room, shower, and possibly a small (prepared) kitchen/living area accessible via a separate exterior staircase. This could allow for a (moderately attractive) granny flat or secondary apartment that could be used as a home office or a teenager’s apartment. So far, this is just a concept.

However, the right plot with 2.5 floors would appeal to us more—and also make more financial sense. But it’s subject to an allocation process.

That is, well, an optimistic floor plan. Just imagine it realistically furnished and used with three children and a home office.

The western plot is significantly better. The knee wall should be 1.2 m (4 feet), and large dormers are also possible. However, with that plot, you have at least 140,000 less available for the house construction. That corresponds to at least 260 m² (2,800 sq ft) more land priced at 500 euros per m² (about $52 per sq ft)?

How large is the middle one?

Yes... especially since we would have nearly 30m2 (320 square feet) less floor area. Okay – no chance.
