We are planning to build in 2022; the planning begins

Personally, it would be too dark for me.
It would be different if the bedroom is the open kitchen.
I would only plan such a roof if the window compensation is in the same room next door.

We are doing exactly that. We have planned large patio doors, with a fixed roof above the terrace. To the left and right of it, still in the same room, there are floor-to-ceiling windows so that it doesn’t get too dark overall.

Thank you for your opinions. We will try to watch it live and then decide.

One thing is still unclear to us. If we choose a general contractor and then sign a contract, what is the sequence until one applies for financing? You have to know all the costs first, right, or can I give the bank approximate values? So the offer amount + approximately €35,000 for fittings (no kitchen) and the estimated additional costs?

The bank wants an offer from the BU/ GU/ whatever. At least that was the case for me.

We only had the GU offer, removed some individual trades from it, but have not yet received offers from all non-GU trades. I simply made a list with estimated costs. So for example, augmentation bathroom 15k, painter 10k, etc. If I had an offer, like for the electrical work, of course I included it. I did the same for the ancillary construction costs and outdoor facilities. All estimated. It went through without inquiry. However, this will strongly depend on the bank and the loan-to-value ratio (ours is 75%, I believe they don't check that closely at that level).

We only had the GU offer, also removing some individual trades there, but not yet offers from all non-GU trades. I simply made a list with estimated costs. So, for example, bathroom fitting 15k, painter 10k, etc. If I had a quote, like for the electrics, I of course included it. I did the same for ancillary construction costs and outdoor facilities. All estimated. It went through without inquiry. But that will depend heavily on the bank and the loan-to-value ratio (ours is 75%, I believe they don't check as thoroughly then).

Ours is also below 80%. Ok. Then I just have to estimate well and rather too high than too low.
