What do you think about the topic of a tent roof? Does it look good with a house width of 10.5m (the rest extension has a flat roof) and as flat an angle as possible?

The architect once casually mentioned that a hipped roof does not look so good with these house dimensions. However, we prefer a tent roof (i.e. pointed), as it probably looks flatter/better.

An alternative might possibly be a flat gable roof.

With only 62.5 cm ridge length, I agree that it’s better to design the hip roof as a pyramid roof. The resulting difference in pitch visually merges. If the entrance porch extended all the way up, yes – at least if the corner windows were left out. As it looks now on the floor plan, it’s styled like a city villa, so the pyramid roof clearly fits better. With the gable roof, the chimney would also be located in the ridge here.

In the meantime, we have another variant, after a quite different basement offer came from the GU:

The original smaller, but actually sufficient for us, floor plan with 130sqm living space WITH basement. If we include the necessary foundation columns in the slab calculation, the basement costs "only" about 25k€ more (although basically in shell condition, which wouldn’t bother us, main thing is it’s there).

We would then have 130sqm living space and 65sqm usable space for somewhat less than the 160sqm variant without basement. What I didn’t like about the latter version was that despite 30sqm more, we don’t have a single additional room. We don’t need the 20sqm children’s rooms either; 15sqm each is enough.

What do you think?

I'm back. After a short break, things will probably continue with a more committed, likeable architect and a construction company that appears more trustworthy.

I have the following offer for the planning:
- Submission planning approx. €2,300 (approx. 35h, depending on actual effort)
- Structural analysis (without reinforcement plans) €1,400
- Energy performance certificate €600

Are the amounts okay and realistic?

Hello! My last post was a monologue but I’m checking in again.

In the meantime, we have re-planned a bit, and this time by ourselves. It’s not so easy to conjure up something convincing. So far, no “professional” has managed to do it right away, unfortunately. Apparently, for good basics, you practically have to try it yourself again and again, even if you’re more of a layperson…

It probably goes in the direction kindly suggested here before by 11ant and ypg. With the difference that it will probably be 2 floors + a basement, the latter partly because of the terrain heights. We would prefer a staggered shed roof that allows a full wall height at the front on the south side (or at least a high knee wall) and is somewhat lower at the back on the north side, among other things to comply with the allowed wall height (max. 7.75m).

Roughly, it should look like the attached plan. The house is pushed with minimum distance to the east boundary. 6x6m carport + possibly 3m roof extension (marked dark gray) directly at the house with entrance in the southeast corner. Even if it is somewhat compromised, this would please us best. Alternatively, the entrance could be made from the east if absolutely necessary in terms of the floor plan.

It was important to us not to completely block the view to the south-southeast and still to be able to come directly and dry into the house (we find it hard to let go of this hehe), hence the “semi-open” solution with the carport. With the basement, we also don’t necessarily need a huge garage. Another must was a nice southwest garden that should be as level as possible (through 1m fill in the west and 0.5m excavation next to the carport/driveway). The driveway would be marked light gray, depending on the variant 6-8m long.

There is still some garden left at the back in the north, which should also get a bit of evening sun in midsummer from the northwest. Maybe the house could be pushed a bit further forward to have more garden area here (1/3 north garden - 2/3 south garden). In the green-marked area, a level garden section with access to the basement is to be created by excavation.

The floor plan is still a work in progress. But I already have quite concrete ideas. Planned would be about 130-135sqm living space on the ground floor + upper floor + basement:
GF: living room, dining room, kitchen, pantry, WC, hallway
UF: bedroom with dressing room, 2 kids’ rooms, bathroom, hallway
BSM: technical room, utility room, storage room, possibly later an office/guest room and small WC-shower.

What do you think about it?

By the way, both the architect and (more likely) the general contractor have confirmed to us that we should calculate 12-13% of the house price for the basement instead of just the slab. Is that realistic? We don’t want the basement to be finely finished, initially even a shell variant with at least screed and plaster applied would be enough.

P.S.: Another alternative would be the variant described by ypg with ground floor + lower ground floor (with 1-2 basement rooms) and thus a lower building volume, especially if you wanted to have a slightly bigger north garden and use it more. But can something good come out of that with the not very steep slope with only max. +/- 1m permitted filling/excavation? I imagine that only a smaller area in the northeast would fully look out of the ground and a large part would be “underground” (also marked green in my current sketch). Or am I mistaken?
