Floor plan for building a semi-detached house - ideas

There are really enough threads here about construction costs, it also varies regionally and depends on the technology used. I would apply 200/sq m as a minimum. Plus basement. Plus ancillary building costs. Plus garage. Plus outdoor facilities. Since the basement is supposed to be finished, it will probably be within the thermal envelope and can be considered as an equivalent room but also with the same price. If you build together in terms of time, you save some ancillary building costs. There are too many unknowns here for me. Too much energy is wasted here on things that are not yet ripe. Have a look here in the forum for what you can afford and then create your room program. At the same time, the style and so on must be discussed with the construction partners. Was that a developer house?

What do you mean by "Was that a developer house"? Do you mean the floor plan? I created it myself based on a finished floor plan I found on Google.

I’ll answer myself: you want to build with an architect. Then you should ask him what is possible based on the development plan and costs. I think playing around with floor plans is fine, but not before it is definitely clear what is feasible. Why do you want to move walls now when the architect is calling up costs by saying a basement is not possible? Also, you mention a “slope”: you have to see how and where the terrace is possible at what height—how high the house will ultimately be, whether the entrance must then be designed with a stair landing. And whether you then don’t also resort to a house corner or angle... the fewest semi-detached houses are rectangles; for example, they have the vestibule set back, a bay window, or a terrace integrated into the house. Often, the upper floor is even made half a meter wider than the ground floor... but all this is a matter for the architect and your coordination with the building partners. Sorry, but for me, that’s just hot air for now, at least with the information you’ve provided. Off to the architect!

I don't get it. What about the maximum wall height of 6.20m? Isn't that exceeded with the monopitch roof on the 2nd floor? Or does the limit no longer apply to the set-back floor?

I was thinking of a set-back floor on the street side without setback and with knee walls up to the eaves height, and then with a monopitch roof up to the "ridge height". However, this would probably have a considerable piece of knee wall and could be enough for a home office (to which roof terrace connections would be attached).

A pitched roof or a set-back floor also belongs to the balancing process

In my scenario not or, but and. I don't really see a flat roof set-back floor here...

With set-back floors and monopitch roofs there are different opinions about wall, eaves and ridge heights. For example, it depends on how far the set-back floor is recessed. The fact that the current BayBO no longer includes the full floor concept doesn't make things easier.

... a setback (from the street front - eaves side), however, would probably even be necessary on second thought, in order to achieve a spatially sensible set-back floor with the given heights.

On which side is the other house? Does the garage/carport then go directly to the other house side? What about windows then?

The other house is here on the left side of the plan, the garage stands at the top of the plan in front of the playroom.

With these "uncoordinated" semi-detached houses you hardly know what’s going on an arm's length further.

I generally advise against planning semi-detached houses past each other. From my point of view, semi-detached houses are fundamentally unsuitable to be erected by individual builders with the party wall as the boundary of the planning "horizon".

A mezzanine or 2nd upper floor seems quite unlikely to me. Expanding 4 floors - that first has to be paid for. There is not much leeway in the floor plan. It will probably always come down to something similar.

Attached is a proposal with [KG] (omitted), [EG] and [OG].
A shower and an additional bedroom downstairs naturally take away from the spaciousness of the living room. Here I would really think carefully about whether that is really necessary.
Otherwise, you can move the kitchen to the entrance and then have a lot of space and freedom at the back.
Upstairs I would prefer an additional master bathroom rather than a dressing room. But of course, you can do it however Nolte does.

(Staircase 190x280 is not a landing)

Wow, I am impressed :-)
Thank you very much for the great proposal, I like it very much at first glance :-)
We really have to think carefully about the additional room on the ground floor.
There will almost certainly be no second upper floor; it is probably not really in our budget and it also has to match the profile of the neighbors.
