Hello,
so, similar to our previous single-family house project, we are now starting the planning for the multi-family house. The title was deliberately chosen to be the same as the single-family house thread.
https://www.hausbau-forum.de/threads/baubericht-einfamilienhaus-1200-eur-m.35362/
So far, we have purchased an old carpentry workshop that will be demolished.
On February 16th, the building inquiry already submitted will be discussed by the municipal council. The question concerns the development with 3 full floors and a flat roof.
At first, I found a floor plan that I quite like and whose dimensions almost fit perfectly.

I’m still unsure about the elevator and whether it’s really worth the $30,000 (offer from Kone). Possibly, we will prepare the shaft for later installation if accessibility becomes necessary. The toilets would be removed to save costs.

Top floor setback occupying only about three-quarters of the area. A roof terrace is planned all around, on the side, or just at the back—this is quite common in the local area. With the penthouse, you usually have a roof pitch of around 12° (about 22.6°), so it’s not a flat roof and visually it doesn’t stand out much. Having an open ceiling on the top floor creates significant "luxury" in terms of height without sloping walls, and you save the cost of the uppermost ceiling.

Presumably, some mild objection was raised because I had to add some filler text to meet the minimum length "rule" :-( I thought I had warned you.

In my opinion, it then qualifies as a full storey. However, you can argue that by setting it back, the building looks less bulky, is lower than with a pitched roof, and casts less shadow. Let me ask again: How big is the existing house? Length, width, height?The main house is currently 20x12m (66x39 feet). However, the entire plot is almost completely surrounded by a single-story workshop.
Based on this argument, I'm not even sure whether the local authority would allow anything other than a full storey, and not just two full storeys with an uninhabited roof.

A recessed top floor occupying only three-quarters of the area. Around it, on the sides or just at the back, a roof terrace is planned – I see that very often around here. With a roof pitch of about 12° on the "penthouse," you don’t have a flat roof, and visually, it isn’t too noticeable. An open ceiling at the top adds considerable "luxury" in terms of height without sloped ceilings, and you save the costs of the last ceiling.I would like to do that, but the local authority has repeatedly said they want a pitched roof so it fits better with the surrounding buildings. Getting into endless discussions now about what is legally possible doesn’t help me.

This interpretation is correct to my knowledge – as I already mentioned this morning at 12:40 a.m. Probably the moderator took issue with me having to write additional notes to meet the minimum length "rule" :-(Indeed, I also had it confirmed by the Environmental Agency. It appears my architect misinterpreted the regulations.
However, due to the currently very high raw material prices, I am not in a big hurry to start construction.

Due to the very high raw material prices at the moment, I am not in a rush to start construction after all.You are now planning 19 x 13.5 m (62.3 x 44.3 ft). You have significantly reduced the size of the house compared to the first design, and only slightly increased it compared to the existing building. The old workshop areas are no longer included. You are setting back the upper floor to soften the bulky appearance. You can accommodate up to 12 parking spaces. These are all good reasons. You have time. I would submit this again as a preliminary enquiry.
Why not consider a full renovation?
Are you hoping raw material prices will go down?

Why don’t you do a full renovation?
Are you betting on falling raw material prices?The existing building is basically a total loss. I’ll be glad if it doesn’t collapse on its own before demolition. I do think prices for wood and insulation will ease a bit once supply and demand balance out again.

Otherwise, they would have approved my inquiry. But I just realized that I could never provide enough parking spaces for three full floors.
In the meantime, I have worked out the design in more detail. Unfortunately, the parking spaces still don’t really work. I would rather call the “gardens” prison yards, since the outbuilding is right on the boundary line. For bicycles and storage, I planned an outbuilding. The neighbor’s land is anyway 3 meters (10 feet) higher than my plot there. I planned the washing machines and additional storage in the attic, as suggested by 11Ant, which could save me from having a basement. Is it reasonable to do laundry in the attic? What do you think about the design?
