Semi-detached house with unequal halves = different floor plans

The draft is not quite what we want yet, but it is heading in the direction we worked out with the architect.

Well, that's good then. I wasn't sure if it was actually as Yvonne had suspected. After all, the wishes at the beginning were "somewhat" different.

In the meantime, another architect was also highly recommended to us, with whom distant acquaintances had built years ago in our building location. They have now sold this house because they got an even better plot of land (village/relationships, after all) and will build again next year with the same architect and his construction company because they were so happy with the house and the execution. We met with him at the plot and discussed the project. I have to say, he was the first who thought about the project consistently from the perspective of the plot, and not just how to adapt to it. We sat together for a long time and created a room book; ideas were flowing, and we are now waiting for his (quasi counter-) design. The idea of two building bodies with their own gable roofs without eaves at a 90-degree angle was up for discussion. (At this point, 11ant has probably definitely dropped out...) I still can't quite imagine it, but nothing is set in stone yet, or I simply have to see it. Assuming we would build with him, it would of course be annoying to have spent so much money on the other concept study. On the other hand, we still have another string to our bow. I am curious what will come of it.

Well invested money - no matter the outcome.

To what extent would a different roof design affect the with two full stories, if the footprint remained approximately the same? That would have "only" consequences for the attic, right, or where is my flaw in reasoning?

Much less than everything, it would not change that: different roof = different height lines in the attic = a) different headroom above the stairs = different staircase location and b) differently distributed standing height in the attic = different floor plan and as a consequence of all that the footprint remaining the same is also in question.

But if the offset is "pointless" – why not in our case?

If the shed roof halves belong to different houses, in my opinion the building structure outweighs the possible additional lighting.

Same pitch, same eaves height does not work with the maximum ridge height. That was tried! Then it would rather work with shed roofs that meet on the party wall to form a large gable roof.

I consider that an indicator of an awkwardly chosen difference in house width and/or roof pitch.
I don’t recall right now: did you ever follow up on my suggestion of an angled party wall?

The workspace is located in the "studio", which will serve as a home office, guest room, and hobby room.

A "studio" is just as much a euphemism for a leftover area as "hobby room" in the basement. And the usage accordingly is a multifunctional chameleon stew. From my point of view, these are architecturally built disgraceful spaces. These are rooms for the realtor’s phrase "everything is possible." The difference is usually this: in the studio the clutter is more intellectual (never or forever unread books), whereas in the basement more bachelorette party supplies are hoarded.

The idea was two building volumes with their own gable roofs without eaves at right angles.

That means the ridge direction of the second half of the house is perpendicular to the first?

(At this point 11ant probably gave up for good…)

(At this point I hear 11ant laughing over the roofs.)

? ? ?

We don’t need much space for sleeping, I find small and cozy more comfortable anyway.

It’s not just about sleeping space (area), but also about room volume. You don’t want to sleep tired. That means the room needs either appropriate air exchange rates or the volume in which the used air does not “condense.” I would be reluctant to install another controlled living space ventilation circuit with turbo exchange rate just because I had planned the room too small.

So the ridge direction of the second half of the house is perpendicular to the first?

P.S.: taking a look at the house of along with the mother-in-law wing in the house pictures thread might give a new direction to the idea concerning the building composition.

Oh, you can also talk roofs to death
Each has its right to exist.
