Dear forum members,
I have been following this forum for some time now and have already gathered a lot of helpful information for our planned house construction. Many thanks for that!
We have now finalized our floor plan, and I would appreciate your expert feedback on our designs.
P.S. Since the location and orientation of the house and garage on the corner plot are quite fixed and conform to the development plan, my main concern is the room dimensions and whether the layout, in your opinion, works well in reality. Of course, I am open to any suggestions and improvements.
Thank you in advance!
Best regards
Development Plan / Restrictions

Floor area ratio (FAR): 0.4
Gross floor area ratio (GFAR): 0.8
Building area boundaries, building line, and limits: 3 meters (10 feet)
Edge development: Garage directly adjacent to neighbor’s property, up to 9 meters (30 feet) in length

You should seriously consider patenting the clever trick of flooding your lot flat by interpreting the one-meter contour lines (on the otherwise nearly unreadable) "surveyor’s map" as quarter-meter lines for the floor plan design!
Understandably, this means I won’t be addressing any further details.
Except, of course, to add myself to the list of those who caught you on the planning mistake of designing the upper floor before the ground floor. You can tell by the blood in the shoe (that’s why I’ll be calling it the “Cinderella planning” from now on) [hheh].

hanghaus20236 Mar 2024 14:31Unfortunately, the labels on the contour lines are unreadable. Could you upload a higher-quality version? I hope that @11ant did not misinterpret something here. If I use your data, then the contour lines have a spacing of 0.5 m (20 inches).
In your opinion, the building area is fully utilized. Please mark it on the site plan. If there is a zoning plan (building permit / planning permission), please show it to us.
At least show us a plan so we can understand the surroundings. Where is the road? Is that a retaining wall in the southwest?

@ypg A height difference of 1 meter (3.3 feet) over 9 meters (30 feet) is feasible. I don't see any problem with that. We have 1.2 meters (4 feet) over 8 meters (26 feet), which still results in a relatively gentle driveway compared to many in this area.
That said, I’m not saying I like the positioning of the house and garage. I estimate the landscaping will cost a large five-figure amount, unless a raised terrace and stairs to the garden are planned.

What are aluminum stud walls? I have never seen those before.

I believe what is meant are standard lightweight partition walls with metal profile construction. Here, the original poster would have been wise to explain why, in some places, solid timbers are apparently preferred as the framework—does he want to build these himself and leave the metal stud work to the professional (I hesitate to say "trained") drywall installers?
