Floor plan of a two-story house with a slight slope

I’m attaching the development plan, but it is quite open.

: How big is the western house in your drawing?

I want to have everything on one level so that I can use it that way later, even if it’s not certain that I will use it—who knows how much time I have...

The following rooms should already be on the ground floor:

-Full bathroom (without tub, but with double sink and some space around, about 9 m²)
-Bedroom about 16 m²
-Additional room as office/child’s/guest room 10-12 m²
-Kitchen 12-14 m²
-Utility room about 10 m²
-Guest WC 2-3 m²
-Living/dining area 30-35 m²

I would build the upper floor instead of a basement because it is probably about the same cost-wise, but I can use it better as a hobby/children/office room, or alternatively as an apartment to rent out.

That’s how I came up with the initial concept.

Regards + thanks!

Unfortunately, the permitted floors in the plan cannot be read. At least a semi-detached house is allowed. Dimensions of the western semi-detached house half north: 9.5 m; south 8 m; west 11.5 m = 100.6 m2 * 0.8 = approx. 80 m2 living area Roof with kneewall then approx. 60 m2. There are contour lines but unfortunately nothing can be read there either.

I would take a look at what the neighbors have built. For example, what heights of the ground floor finished floor are in relation to the street. The municipality wants to determine the heights!!! How have the neighbors designed the number of stories?

It’s best if you post your plot with the immediate surroundings as well as the use template again in a legible resolution, then something could be made of it.

Well, the “concept” of a strap-and-helmet-parachute house for a maybe-not-even-own-use and with a lighted, rentable but actually unnecessary floor on top, I’d say not only I find that, to put it mildly, pretty crazy. What are people smoking for that? If you have the budget including that for the additional apartment lying around, your own use’s timing is kind of the investment horizon of the maybe-once-for-you planned rental unit. There are probably several finance savvy folks ( , and: what’s the Serbian benchwarmer actually doing?), who would agree with my previous paragraph. And in case you’d have to borrow even part of that money, that would probably be even more emphatically true. I hope it’s roughly understandable to you why I can only very limitedly follow a planning thread here and why I’m itching badly to approach a popcorn dealer on quantity discounts (analogous to your plans, only as a very open option, of course). Hypothetically putting myself for a moment into the role as if this were a serious planning thread (and acknowledging your rejection of my duplex proposal because of stairs inside the residential units), as I said, I would plan an apartment for you and clone it into a city villa style straight-walled upper floor or at least a high knee wall attic (again, if the first occupant of this second apartment doesn’t suggest otherwise, 1:1). Above your utility room, a utility area (HAR) could be placed on the upper floor and accessible there from the staircase. But that’s basically it for fee-free suggestions. And you shouldn’t plan this apartment for some someday-me, but concretely e.g. for your if-the-laggards-are-out-of-the-house-me. Maybe even with the horizon that when the younger child comes of age, they both become your tenants of the upper floor as a shared flat. A universal castle-in-the-air for never-neverland-and-possibly-early-days is in any case (i.e. whether the money has to be “built away” now or still has to be raised) nonsense to the power of three and a half. Buddy, you are now zweifäzzisch and Äleggdroinschinjör ..., to quote Badesalz once ;-)

In the west, 2 neighbors have access via the path in the north. That is something to consider.

I somehow can’t bring myself to build the house in the south and the garden in the back, especially since all the other houses are also located in the north and also have the long driveway. They have partially bought a snowblower for that.

I can’t place one or two houses or garages at the front by the street in the village and take away the neighbors’ view/sun, I will stick to the style prevailing there. It is not about maximum profit from rental or living space, omitting garages, etc. In our village, only visitors’ cars stand outside; the rest are in the garage.

Yesterday I measured the heights; for that, I set up a laser level at the southeast boundary point and aligned it to 1m height. Then I measured the dimensions, subtracted the meter, and drew it into the plan.

The height difference in the “building envelope” is 1.34m (-0.56 to -1.90m). The heights are marked at all corner points.

How would you see the profitability of a basement compared to terrain construction / filling up or dredging for a basement?

Is there actually a subsidy for a second residential unit if you don’t build a KFW40 house?

Here again are the details from the development plan:
