Hello to all forum readers,

I have a question for those of you experienced in house construction and floor plan design. Is it possible to fit two residential units on a footprint of 185 sqm (building area approx. 9 m x 20 m (30 ft x 66 ft))? How many square meters are typically lost to walls and staircases?

I have done some preliminary calculations using guideline values and created a rough floor plan. I came to the conclusion that it will be very tight if comfortable room sizes are desired. For this reason, I would really like to hear the assessment of someone with experience.

The goal is to build a 2-room apartment and a 3-room apartment with a balcony or terrace on each floor. The multi-family house is planned to have a total of 6 units (2 full floors plus attic).

Do you think it is feasible to build approximately 78 sqm (840 ft²) and 65 sqm (700 ft²) on one level within a floor area ratio of 185 sqm?

Best regards,
Karl

It might be tight.

Where will the building services be located, and will there be a basement?

The stairwell must be large enough for all housing units.

Depending on the target group, you should also consider space for strollers and bicycles.

The house is detached (town with 25,000 inhabitants, Rhine-Main metropolitan area), building services are installed in the basement, and bicycle parking spaces are planned outdoors.
The size of the stairwell is indeed a problem and has been designed small due to space constraints.

I tried to stack two residential units in this thread https://www.hausbau-forum.de/threads/grundriss-haus-mit-2we-zur-vermietung.16693/page-3#post-148696. Just to give an idea of the proportions:

Building footprint = 107.2 m² (1154 sq ft)
Living area ground floor = 70.5 m² (759 sq ft)

I would just accept the staircase layout as it is for two residential units, but not for six units.

Note that a small technical room is included in the area here.

So here, semi-detached houses with a floor area of 45sqm (484 sq ft) are planned *schenkelkopf*, which is really quite spacious!
