Floor plan of a single-family house, feedback

Main stuff in the utility room, however, all need walls. Meter, house connection box, photovoltaic + storage, washing machine, and so on and so forth. I would first check in the utility room whether the wall space is sufficient for my needs. If there is still some left over, then a door can still be considered.

It’s definitely great. But I would first see if it works spatially.

Hey, the washing machine doesn’t necessarily need a wall. It can also stand freely as long as there is water, electricity, and drainage. (Yes, people usually don’t do that, but unlike the meter cabinet/distribution, it doesn’t have to be mounted on the wall).

But yeah, it’s clear. Wall space is premium, but it has already grown considerably compared to the initial plan, so there is definitely more. But—if no door goes there, it’s no big deal, it’s just a possible nice thing and currently an open question.

Photovoltaics on a flat roof is completely easy. I would build an east-west system with a super simple Triton mounting (or another chip-free system) and since you come from electrical engineering you will also find an inverter that suits your interface preference.

That is still open. "It will come, prepare pipes" is the status. Rough idea—but that will be discussed with a photovoltaic expert, maybe going outward to the east and west on each side, and something towards the south in the middle. I have free possibility in all directions up on the roof. Only on the garage, if I also put some there, east-west won’t work because of the house next door. We’ll see how to handle the strings and whether it makes sense. But I will get someone who knows more once I have the basics. So while the building permit is with the authorities, such additional trades are being worked on.

Regarding - I have no experience with the quality of the company. What I positively remember is a salesperson who switched from Fingerhaus to the software industry and where I also took a position.

It depends—as usual with salespeople—greatly on who you get and how well you click with them. Ours locally is also great.

So you could indeed have chosen another construction company? – then the tax trap would probably have been avoided. Who were these others, and where did they fail (or: couldn’t convince)?

Another area in the building field with another company. Not on this property. Here there is basically Fingerhaus below, above "BonVie". They build semi-detached houses with a—so far as I understood it—relatively fixed floor plan, and neither appealed to us. Ok, we didn’t ask much about if/how you can make changes—but one of their advertising texts includes "fully financed" as a plus and also shows possible changes. Sounds rather rigid to me—but I might be wrong, that’s just our impression.

A green roof is good for climate and also generally beneficial for biotope. But its structure is critical, and the substrate for planting weighs.

I shouldn’t care much about the weight—that’s Fingerhaus’s issue. It’s already planned accordingly; it will be fine.

Edit: On lebeninfulda.de/Grundstücke you can find a sold property with 576sqm. Is that the one from the OP?

Caught.

Papa State is already happy, the property has been bought by the OP.

Well, oh well. But there isn’t much choice here so I can’t optimize everything. So I just swallow the toad with the money to the state.

We actually had contact beforehand with another provider who builds here in Fulda in a top location. Whoever wants to look, Wood You Fulda. Heritable building right, also fixed floor plans already, I wanted to adjust small stuff and got stuck. Also quite rigidly predetermined.

And that was basically it for what can currently be found. Somewhere in 2026 something else should come in the area, but then it will be 2028 before it’s ready to move in. Yikes.

@wiltshire and with us was immediately out because of the salesperson. I have never encountered something so aggressive.

See above, it probably strongly depends on who you “get.”

The OP is not building with Fingerhaus

It’s basically Fingerhaus, just described differently.

Yes indeed, it’s Fingerhaus.

Ok then it is Fingerhaus. I thought it was another company. There are many companies in our area.

That is still open. "It will come, prepare pipes" is the status. Rough idea – but that will be discussed with a photovoltaic expert – would be whether maybe on the outside each towards east and west, and something in the middle towards south.

Good that you are planning with empty conduits. You can still determine the orientation. Also plan the location for the electronics and leave the appropriate space – there are spacing rules here as well.

The weight should be pretty irrelevant to me.

I agree, it is part of the house costs, but I wouldn’t calculate an extra surcharge for that either.

Rough idea – but that will be discussed with a photovoltaic expert, [...] But I’ll get someone who knows more about it as soon as I have the basics. So, while the building application is with the authorities, such additional trades will be addressed.

Better not. You’re building a prefab house with a flat roof. Nothing will be cheerfully built raw at first and then broken up again where pipes need to go, and simply exchanging an antenna tile is also not an option. Here the stone mantra applies metaphorically: rather take what your usual installer has the most experience with instead of the absolute best from theory. Don’t be the extra cook who spoils the pot. Clarify this early on, limited to the controlled options of your general contractor, and let them coordinate it.

Basically at the bottom is , above that "BonVie". They build semi-detached houses with – as I understood it – a relatively fixed floor plan, and we were not satisfied with either. OK, we didn’t ask much about whether/how many changes could be made.

Detached houses and semi-detached houses are generally not for the same types of builders. You can find the design possibilities discussed here in several threads if you follow the keyword “usual suspects” in my posts: in short, you can wish for electric belt winders there. But that must also be the case: semi-detached houses in such projects are built by teams in assembly-line fashion – that doesn’t work if buyers waver back and forth between eighty-three options several times. Just cleaning up an email ping-pong so that the kitchen team doesn’t get confused is an unacceptable work step. 08/15A to 08/15H – that’s all there is, otherwise neither price nor time targets can be met. Serial cookie baking doesn’t work any other way. Hence also the unsuitability for individual builders or the need to be able to assume a willingness to compromise for intermediate houses.

OK then it’s Fingerhaus. I thought it was another company. There are many companies in our area.

In most areas, only one of the many carpentry businesses has developed into a prefab house company.

there are also some from the prefab house guys Rensch-Haus, Hanse Hause, Bien-Zenker downwards everything open up to the carpentry with 2 houses per year

there are also some Rensch-Haus, Hanse Hause, Bien-Zenker from the prefab house folks, everything open down to the carpentry with 2 houses per year

But they are not all located in the same area.
