House Design
Planner:
- Do-it-yourself
Estimated cost: 800,000
Personal price limit for house including fixtures: 900,000
Preferred heating system: geothermal energy, trench collector

If you had to give up something, which details / features
- You can give up: balconies, wet rooms in children’s rooms, one or two corners of the house
- You cannot give up: elevator shaft, fireplace

Why is the design as it is now?
The plot is in a good urban location. Therefore, the allowed building density should be used almost to the maximum. Floors should be easily separable. Renting as apartments should be possible without major remodeling in case it becomes necessary.

It would be logical to place the house as far north and east as possible. However, this would completely block the southern exposure of the northern neighbor. This has already been suggested by planners but is out of the question for me. On the other hand, the neighbor is willing to agree to terrain modifications on their property if necessary. Placing the house to the west is difficult due to required setback distances, as the plot narrows. A terrace house placed fully to the west would be possible but is not desired.

I am fully aware that the design is suboptimal in some respects. Therefore, I appreciate any criticism, comments, and suggestions.

Thank you for all the feedback! Especially for the suggestions from @ypg on how to improve things more concretely.

I will probably need to consult an architect again. Unfortunately, the last one ended up designing almost 80 m2 (860 sq ft) of hallway space (excluding stairs, elevator, and entrance area). That’s why I’m somewhat skeptical.

I can’t respond to everything in detail, so here’s a selection of comments:
ypg schrieb:

Having many central shafts is not an option. If pipes get clogged, waste goes under the slab, which I consider a major technical design flaw.
There would only be a single central shaft, with one drain pipe. The other drain pipe would be close to the north exterior wall, which seems unproblematic from my layperson’s perspective. That still leaves one of the two required drain pipes running a long distance under the slab. It makes sense that this is less than ideal in terms of clogging or wear. However, it doesn’t seem unusual when looking at the Google image search (see attachment). Are there no workable technical solutions for such cases?

The parents’ area is illogically designed. If I want to sleep, my husband has to constantly pass through the bedroom to wash, get dressed, use the toilet, then leave. The benefits of a walk-in closet are not realized.
If you don’t want to wake your partner, couldn’t you take your clothes and go to the bathroom via the hallway?
ypg schrieb:

And I want to access the terrace directly from the kitchen without having to open doors.
That could easily be solved with a sliding door.

I can only imagine a toilet without a window in a studio apartment in a multi-family building.
I fully agree from an objective point of view! That it doesn’t bother me subjectively is probably due to three reasons:
  • I have never had the pleasure of living in a place with a window in the toilet for over 30 years
  • I work in a public building where the toilets have no windows
  • A controlled mechanical ventilation system will be installed

I only find a granny flat worthwhile if, for example, you are bringing your parents into the house, need a nanny for your five kids who would live there, or maybe a caretaker in case of disability — those kinds of cases.
That is exactly what the granny flat is intended for: au-pair, caregiving, guests, etc. Renting it out is not planned. I think it would be too small for that anyway.

Think about possibly dividing the house later into a two-family home and hope that, for example, one of the children moves into the upper floor. This includes planning a separate stairwell from the start that could later be divided with a wall.
Separating the stairwell would be possible, right? That’s why there are separate entrances on the basement and ground floors.

The unusual wall thicknesses
The exterior wall consists of 25 cm (10 inches) brick, 24 cm (9.5 inches) mineral wool insulation, plus a ventilated facade with cladding (if that’s what was meant), or concrete plus XPS insulation in the perimeter area.

The granny flat runs over the lawn, for example
The outdoor area has not yet been planned. Of course, that area would not be just lawn.

I don't see any possibility of separating the ground floor and first floor. Only the basement can be separated – but no one wants to live down there.

Oh, there was already an architect involved? Then you should show their proposal for comparison.

I do not have the rights to the design.

I don’t see any access to the bathroom on the ground floor.

Kind regards
