Apartment for parents: 210 m² single-family house and 80 m² apartment

That is still not a suitable plan. You have drawn everything quite tightly and roughly. If a professional construction plan is to be made from this, supply lines, shafts, etc. still need to be added, then sometimes it might also get tight. Is the room in front of the heater now a cloakroom? Almost 13 sqm?

Stupid question: what is happening in 4 weeks?

Then the land will be developed and must be paid for, a financing will be necessary for that. Today we could have signed for the larger first object, but that would have been a lot of money as well.

Storage and cloakroom.

Sorry, I'm out, if someone wants to obviously run headfirst into disaster, they should be left to do so. But please promise me one thing, I want to see photos of the shell construction and the finished house! If you find someone who can/wants to build it like that....

You don't even know if it will work structurally? Who is doing the structural engineering? What about supply and sewer lines? Are there cross-sectional views? Are the sizes of the windows determined? Parapet heights?

Oh, and by the way, do you really believe that you can start in 4 weeks with a finished plan? Building permit? Development plan? Do you already have a construction company?

So my opinion? I bet nothing will happen in the next 6 months....

Then the plot is developed and would have to be paid for, for that a financing is needed.

Have you already talked to the financial institution about the situation? Why not first the plot, then to the architect or general contractor and plan and build something sustainable?

As KingSong says, are the requirements even met? Do you have someone who could start immediately? Especially now, when all the construction sites are starting, the order books are packed, with a lot of luck you might find someone who still has availability around October. As I said, that presupposes all the things KingSong mentioned – and possibly a few more.

Even if it may seem like that, no one wants to harm you here. I would definitely be concerned if not a single, good point is left on your floor plan – by a variety of forum members. No one can (or wants to) force you to think about it – I’ll now boldly generalize from myself to others.

We don’t have time for that anymore. About 4 weeks left.



I revised the ground floor a bit. The garage is now a bit bigger and the narrow hallway is gone. Would the space for the gas heating be sufficient like this?

Sorry, you’ve been tinkering with this draft for almost a year now. Always with some kind of constraint or moving from the old bad design to the new one. The granny flat is usually terrible for older people, and you keep ending up with corridor-like rooms that somehow seem failed. When I set my brain to 3D mode, it’s just not working at all. Also not in terms of the usual workflow.

And another thing: most people here buy a plot because they have a good feeling about the location. The design then adapts to that. Sometimes you have to let go of symmetry or that fixed-in-stone L shape. L is not bad, but you free yourself from corsets like the ones you have.

You should have heeded our advice a year ago and hired an architect.

You didn’t. What do you want to hear now? That your design is great and buildable? Leaving aside that at a quick glance the last ground floor design is roughly, really just roughly, the best I’ve seen from you here, it is by no means enough for you to magically create something nice with your means within the next two years. You’ve wasted a year. You have to take responsibility for that. That’s how it is. Unvarnished truth.

While you are tinkering with drafts here that in my opinion deserve a grade of 4-6, quite a few people here have had their designs discussed which you could learn a lot from. Not only from the discussions and their results, but also from the original designs. It’s a shame you weren’t involved.

Therefore -> Architect!

I’m out!

Insofern -> Architect!

I have here 5 plans drawn by friends who are architects, I don't necessarily find the plans amazing either.
