As far as I am not wearing the wrong glasses, the garage is placed in front of an otherwise windowed side and in front of the entrance door (?)
Besides, I join the plea not to build a driveway as a maneuvering training ground.
By the way, I still don’t understand why anyone would voluntarily build three bathrooms; they all have to be cleaned...
Man plans, woman cleans
It will probably also be a huge difference between KfW40+ and KfW55.
I would say this is almost a fundamental decision like between hybrid and purely electric cars.
The ground floor is a full-fledged story, similar to a bungalow.
I had already understood the concept of avoiding a full upper floor by enlarging the ground floor, however ...
Then another story (probably slightly set back) is built on top of it.
... I hadn’t noticed the setback of the upper floor at first – otherwise I would have criticized it already: that is double nonsense, meaning a structural cost driver with the added downside of ugly appearance. If you like the Tuscan stepped design, however, I do not understand your rejection of @haydees Schwörerhaus suggestion.
If the upper floor is set back (in relation to the alignment of the outer walls to the ground floor), then we could also imagine the upper floor as a flat roof? Or perhaps as a hipped roof with reasonable slopes (i.e. comfortable knee wall). The two cubes that are not overbuilt in the upper floor could have a flat roof (with terrace) or a hipped roof.
Whether a roof terrace is placed on the two cubes or a hipped roof is chosen for cost reasons, that has no influence on the actual floor plan of the upper floor?
As said, the wish is full story height in the upper floor, then the staircase also works. But since we are not allowed to build two full stories, the upper floor MUST definitely be set back and/or smaller than the ground floor.
Preferred is to have no slant in the upper floor, so everything full room height. Since we only have the regulation 1.5 full stories, otherwise open construction, we are quite flexible.
So what now? – if that is all there is and no requirement for the upper floor to be set back is given, I would also leave it as it is. Terraces on the ground floor protrusions generate areas attributable to the upper floor, so they are counterproductive for avoiding a full story there.
“For cost reasons a hipped roof” – I hadn’t heard that joke before. Hipped roof, because you have too much money?
KfW 40+ is not the cost driver
The floor plan is the cost driver
Without roof pitch and knee wall the upper floor need not be discussed
b. and c. I fully agree with, a. I see differently: KfW40+ without concrete reason is an unnecessary gold plating for fans of bio-labels.
The ground floor must stand, from which the upper floor results for us.
Exactly backwards: first the room program, then the upper floor, and afterwards the ground floor. Plan downward, build upward.
I am open to suggestions. I even expect them! Unfortunately, none came so far...
There were plenty. “Leave that” is no less concrete than “do this”!
Finally a word about the slanted wall sections: not every retro comes back into fashion; this quote from 1980s apartment block architecture is today a minus point for resale. Originality should be used like a spice – not like a staple side dish.
