ᐅ Double-story house with a maximum floor area of 53.3 square meters and a maximum depth of approximately 8 meters?

Do you already have the building permit / planning permission for a semi-detached house?

533 m² (5740 ft²) and 106 m² (1141 ft²) of buildable area are, to me, typical single-family house dimensions, which is why I am asking.

Hello Edwin,

Unfortunately, I don’t have a suitable catalog floor plan to share.

However, I would like to give you two pieces of advice:

1. A high-quality prefab house is usually noticeably more expensive nowadays than a conventionally built solid house.

2. There are also prefab house providers who build completely custom homes. This individuality typically comes with a 15 to 20% premium compared to an off-the-shelf house.

You might want to get a quote from Weberhaus in Rheinau-Linx, Baden – we built a custom-designed single-family home (timber frame prefab) with this company and had a very positive experience.

Best regards,

Dirk

Every homebuilder offering customized design should be able to provide you with a quote.
House catalogs target a broad audience: families of four and homes between 120 and 160 cm² (1,292 and 1,722 ft²). However, it is still worthwhile to request information from companies.

We approached the prefab house manufacturers with our requirements from the development plan and our preferences (open kitchen, enclosed staircase, etc.). After the initial meeting, all of them were able to provide us with a rough estimate. Forget about the catalog prices right away – they never match your specific building project.

Wouldn't it make more sense to build a two-family house given the size and possibly divide it later according to condominium ownership rules (WEG)? If the budget and space are very tight, having only one staircase, one heating system, and just one set of utility connections could offer some advantages.

The entire house would then be about 15m (49 feet) wide and about 7.1m (23 feet) deep...

If I subtract two exterior walls of 0.36m (14 inches) each and one interior wall of 0.17m (7 inches), you end up with a floor area of 6.21m (20 feet) by 6.61m (22 feet) per residential unit, totaling 41m² (441 sq ft). Subtracting at least 4m² (43 sq ft) for the staircase leaves 37m² (398 sq ft) for the rest.
How many people are supposed to live there?
