Floor plan design single-family house with around 150 m²

That doesn't look wilder than a grouper either

If the budget allows, I would soften the basic pattern of the gingerbread house just a little.

I would also have liked to hear such suggestions from the architect... well-founded and justified, it's all no problem. But now having to tinker around again myself, I find that annoying.

The funny thing is the contrast between the almost bland exterior and the wild and "interesting" interior wall structure. You basically get a culture shock. From the outside, you approach a boring plain house and then get startled when you bump into the many corners inside.

With the "rockfish," you are then fixed in the interior design for all eternity.

I would have liked to hear such suggestions from the architect as well... well-founded and justified, that's no problem at all. But now messing around again myself is annoying.

Come on, it's your house. Now planning is already too much for you? Well, have fun building...
Honestly: NOW you still have influence options, I would use them.
And if the budget is not limited (I have assumed that so far) or at least still leaves good room, then if the building window allows it, I would definitely still play around a bit. You won't have that freedom later.

Well, there aren't that many after all. And isn't every shelf standing against the wall a corner? If the corners are well utilized, you don't notice it anymore.

I find the planning already exhausting, especially when you are so restricted. I also wouldn't know where else to tinker. An L-variant doesn't bring any more advantages and otherwise everything is basically well utilized. There have also been enough suggestions here recently, all very nice but not more advantageous.

But now tinkering around myself again is annoying.

Why? - Katja is tinkering for you.

If the corners are well utilized, it doesn't even stand out anymore

If all corners are well utilized, the house gets a charm of a cabin or motorhome. Then the gingerbread house becomes a dollhouse.
