Good evening everyone,
we might be considering building a house sometime in the future, which is why I’ve been following this forum more passively lately.
Given the current prices, I want to use the space as efficiently as possible and build only as large as necessary. However, a few parameters are already set:
How much living/floor area would you say is the minimum required under these conditions? The ground floor area would likely determine the upper floor area here.
Ideally, the house shouldn’t feel too cramped.
I’m asking also because prefabricated houses with this layout and under 180 sqm (1,938 sq ft) of living space are rarely found.
Perhaps someone here has built with similar requirements. Thank you, I’m looking forward to your input.

- No basement
- Utility/technical room on the ground floor
- Home office on the ground floor
- Staircase preferably straight-run
- Open kitchen, dining, and living area (of course)

Whether it is possible to place a home office or utility room in an outbuilding probably depends on the zoning plan / building regulations. I’m not talking about an outbuilding here; this is part of the house and can only be accessed from the inside. Although we had a case where the technical room was actually built in a separate building. Technical rooms can apparently also be built right up to the property boundary 😉

The upper floor is supposed to have one bedroom, two children’s rooms, and a bathroom. That’s basically what we had planned originally as well. The entire discussion can be found here in the forum, and the final floor plan is quite similar to what was suggested here: https://www.hausbau-forum.de/threads/efh-130qm-raeume-ausbalancieren.37772/post-465193
Thanks in advance for the responses. I will of course submit the questionnaire later 🙂
While browsing, this one caught my attention positively (Alpha 162.1 by Danwood).
Do you think a utility/technical room of this size is sufficient? The study is naturally also relatively compact.
Do you have any general comments on the floor plan?

Do you think a utility room of that size is sufficient?That depends on what’s going to be inside. A central ventilation system takes up space. Inverters for photovoltaic systems and batteries as well. Then there are the things that are definitely needed: electrical panel, heating system, main connections, water distribution. If you also want to fit a washer and dryer in there, it’s going to be quite cramped. 9 square meters (about 97 square feet) is usually plenty for a study or home office. After all, you’ll mostly be there alone with a computer.

Do you think a technical room of this size is sufficient? In general, standard floor plans from catalogs can be considered workable as long as they are used without alterations. This especially applies to technical rooms, assuming the heating system is also left unchanged. However, there are significant differences in heating technology: while one system’s boiler footprint may fit, another could conflict with the clearance space required for the electrician working safely. Areas that appear “free” on the plan might actually serve such purposes and therefore cannot be used for equipment placement.

Maybe some of you with similar experiences We have what you mentioned spread over about 151 sqm (1,625 sq ft).
The home office is small (7.5 sqm (81 sq ft)) because I mainly work from home by phone and email and don’t have any files or other work materials there.
Our living/dining and semi-open kitchen area measures 50 sqm (538 sq ft) in total.
We don’t have a shower on the ground floor (which we didn’t want anyway), only a guest toilet (2.5 sqm (27 sq ft)).

It houses the technical equipment (no photovoltaic system, but controlled ventilation, heating, utility meters, electrical panel). The washing machine and dryer are located on the upper floor in the utility room, which is about 6.5 sqm (70 sq ft).
