Hello everyone,

I’m new here because my husband and I have just started looking into building a house. I would appreciate your advice or help with the following matter:

My husband is self-employed and needs a workshop for his work, where some goods can also be stored. Our idea is to have a house where the ground floor (on a slab foundation) would be used as a workshop, storage, double garage (for two electric cars), utility room, bicycle parking, food storage, etc., and the upper floor would be our living area. We don’t have children (and we’re too old for that), so we’re thinking about 100–120 square meters (1,076–1,292 square feet) per floor.

We would prefer to build with precast lightweight aggregate concrete elements, as this is said to be faster than traditional solid construction.

Is our idea completely unreasonable, or is there perhaps someone here who has built something similar?

Thanks in advance,

Best regards
Gudrun

Why shouldn’t that work? A slab foundation measuring 10.5 by 13 meters (34 by 43 feet) creates a house like that. Two full stories, with a 25-degree hip roof above featuring attic trusses as crawl space. Commercial space on the ground floor, residential above. In our area, this is even allowed in commercial zones, which saves on land costs. Karsten

The challenge will be finding a plot of land where residential and commercial use are permitted.

Certainly not nonsense; this is actually exactly the dream house of a good friend of mine. He even wants to build the ground floor with a height of 4 meters (13 feet) to accommodate a truck inside.

From a structural or technical standpoint, I don’t see any problems. You just need to be located in a mixed residential/commercial zone and accept that other businesses might already be making noise at 5 a.m. However, you will have complete peace after working hours and on weekends! If you can live with that and find a suitable plot, why not?

The resale value of such a house probably won’t be very high, as it is quite unusual. You should therefore be sure that you want to live there until the end of your life.

Best regards,

Andreas

Plots belong to areas designated for specific uses, which can be found in the zoning plan. In residential zones (WR and WA), this mixed use is not allowed; in mixed-use zones (MI, probably not in MD—here you might need to check the "textual regulations of the zoning plan"), it is permitted; in commercial zones (GE, you probably wouldn’t want to live in GI zones), the proportion of residential use is limited.

Being too old for children, I would interpret as a recommendation for the future: better to live on one level. So, it is better to live next to rather than above the workshop.

Garage and hall construction specialists are, to put it mildly, not primarily focused on residential construction. It might be a good idea to place a prefabricated house on top (and choose a manufacturer experienced in adding additional floors). Regarding thermal insulation requirements, you have two very different building parts. One building can only be optimized for both with increased effort, which can easily offset the savings from the "shared" floor slab.

Plots belong to specific zoning categories, which can be determined from the land-use plan.

P.S.: There are also plots that are not located within any zoning district, so-called §34 areas, where determining the allowed uses can be more complex and is usually best clarified through consultation with the local municipal authority; and—just for the sake of completeness, since typically only agricultural properties have a chance there—also “outer areas” (rural zones).
