The plot measures 1,027 sqm (about 11,060 sq ft), and the design comes from my architect.
I would appreciate honest and constructive feedback on the floor plan and room layout.

@ypg I think skylights are a last resort. There is still no real view outside.Of course they are. But here, there is a very long wall where no windows can be installed. The window side belongs to the living areas. Some rooms have to be located next to the firewall. This is not a single-family house with four exterior walls! You can’t just say "it’s a last resort" when, in fact, it is simply a practical solution.H
hanghaus202311 Nov 2025 08:38In my opinion, the open space concept makes no sense.
I can't imagine achieving a single-story height that way.
Instead, create a third gable with a pitched roof and use the window front there. Then the upper section can be smaller, and the lower part will be fine without any issues. Nobody really needs the open area in the living space.
I speak from experience. My open space has since been enclosed and turned into a large room with a nice window front.
The acoustics were also extremely unpleasant.

What do you think, @lucaskilam?

Do you mean you have 510 sq m (5489 sq ft) of property now?
What does the plot look like? Do you have a site plan showing the street, orientation, and the plot with the design? Which state is it in?

I appreciate honest criticism and suggestions for improvement, especially regarding:He was online yesterday and this morning. However, you can only suggest improvements if some of his open questions here are answered. I specifically asked about the plot and the access direction/parking options, because that determines the entrance. His entrance is on the side, which makes proper zoning of the rooms quite difficult, and only then can constructive feedback be given. So if I quickly throw out a suggestion, I do expect a response, yes.
