Hello everyone.
My partner and I are planning to build a house, specifically a two-family house with side-by-side apartments. We would live in the larger apartment, and the future parents-in-law would occupy the smaller one. A visit to a home builder resulted in an initial draft. This is attached along with the plot.
I am mainly referring to the larger apartment.
I look forward to hearing your opinions.
Regards
Development Plan/Restrictions
Plot size: 2218 sqm, about 860 sqm (9240 sq ft) covered by the development plan, the rest is outdoor area, building zone according to the development plan

Building zone, building line, and boundary: see screenshot (north at top, south at bottom)
Edge development: yes. Garage may have height issues due to the sloping terrain
Number of parking spaces: 4
Number of floors: 1, with a permitted residential basement due to the slope (excerpt from the development plan: I-full floors are stipulated. The number of full floors is the maximum. However, due to the challenging topography, one additional full floor is exceptionally allowed under § 31 para. 1 of the Building Code because the basement caused by the slope can be counted as a full floor according to regional regulations.)
Roof shape: 23–28° (23–28°) gable or hip roof, orientation open
Architectural style: classic
Orientation: terrace facing south
Maximum heights/limits: ridge height 8.50 m (28 ft), eaves height 3.75 m (12 ft), floor-to-floor height 3 m (10 ft)

Additional wishes/special features/daily routine, including reasons for preferences or exclusions:

House Design
Who designed it:
- Planner from a building company
What do you like most? Why? Terrace access
What do you dislike? Why? Dark entrance area, bedroom next to the main entrance
Price estimate from architect/planner: not yet available
Personal budget for the house, including fittings: 550,000 EUR
Preferred heating technology: air-source heat pump
If you have to give up something, which details or expansions
- You can give up: one double garage
- You cannot give up: terrace access
Why is the design the way it is now? For example
Standard design from the planner? Custom design
Which wishes were implemented by the architect?
Yes, but these have changed. Currently, a straight open staircase leading down would be interesting to create a visual axis from the front door to the terrace.

I think so too: a different design will come out, and whether this one is considered good or not, I don’t see it happening for the reasons mentioned. I don’t consider the design in release status from post #28 either clearly good or bad. And since it is basically already withdrawn, I certainly won’t take the trouble to crop it in Paint or similar to check and mark whether it can be shortened or not. That exceeds at least my willingness to engage during open office hours / social clinic significantly. Right now, I have two patients on the operating table and three more in the waiting room.

I wouldn’t really call the floor plan obsolete; we actually like it quite a lot, but due to budget constraints, we would reduce its size. That’s why I shared my idea on how to do that. So you’re aware that the floor plan from the rehab won’t be reused but will be retired because it is definitely too large. You’ve identified areas in different sections of the plan where you want to remove insulation, about one meter (around 3 feet) wide in total, a bit here and a bit there. That’s what I would call obsolete. I can’t clearly identify the labeled insulation spots anyway. Whether your satisfaction with it will remain after further adjustments is uncertain. Besides, you mentioned that the other part will undergo even more extensive changes. I doubt the generational partition wall will remain unaffected by that. Under calm circumstances, I wouldn’t spend time working on suggestions for your thread, and certainly not with a full waiting room. That should be understandable.
