Hello everyone,

I have been following this forum for several years because I am very interested in the topic of building (especially smart homes). Now that we have decided to actually build, I registered and would like to participate more actively in the discussions.

First of all, I would really appreciate feedback on our first draft for a single-family house.

Development Plan / Restrictions
Plot size: 700 sqm (7,535 sq ft)
Slope: yes, approximately 1.5-2 m (5-6.5 ft) sloping to the south
Floor area ratio (FAR): 0.4
Gross floor area ratio (GFAR): 0.6
Building envelope, building line and boundary: Blue line, site plan
Edge development: garage allowed
Number of parking spaces: 2
Number of floors: 2
Roof type: Gable roof
Architectural style: Modern
Orientation: South
Maximum heights / limits: ridge height 8.50 m (28 ft), max. building length 18 m (59 ft)
Other requirements:
According to the development plan, only gable roofs, staggered shed roofs, and hip roofs are permitted. However, we are trying to interpret the development plan creatively.

Excerpt from the development plan
12.1 Roof shape and pitch, covering and green roofs
Compared to the original plan, previous restrictions regarding green roofs will be relaxed. Freestanding garages are also allowed to have flat roofs, even if these are not greened.
For ecological reasons, solar panels on or integrated into the roof covering are generally permitted and explicitly encouraged. Therefore, when an integrated solar or photovoltaic solution is installed, roof coverings in darker colors are exceptionally allowed.

Homeowners’ requirements:
Pantry, basement, built-in masonry fireplace, built-in walk-in showers on ground and upper floors, laundry chute, direct access from the garage, no balcony but a terrace, double garage, kitchen island
Rooms on ground floor - office, living room, kitchen, dining room
Rooms on upper floor - 2 children’s rooms, bedroom, walk-in closet, bathroom (possibly separate toilet)
Style, roof type, building type - modern, gable roof *cough*, cube
Basement, floors: with basement, 2 full stories
Number of occupants, age: 2 (aged 33 and 35)
Space requirement ground floor and upper floor - ground floor 80 sqm (860 sq ft) / upper floor 80 sqm (860 sq ft)
Office: family use or home office? Home office (frequent)
Overnight guests per year: few
Open or closed architecture: open
Conservative or modern construction style: modern
Open kitchen, kitchen island: kitchen island
Number of dining seats: 6
Fireplace: yes, masonry
Music/sound wall: not necessary
Balcony, roof terrace: not necessary
Garage, carport: double garage
Utility garden, greenhouse: not necessary
Additional wishes / special features / daily routine, also reasons why something should or should not be included
- The house was planned based on experiences from friends who have built (we are basically the last in the group to build)

House design
Who designed the plan: architect
What do you like most and why?
- Kitchen - dining room - living room aligned towards the south
- Ground level access to house and terrace
- From our point of view meets (most of) the requirements
- Gable roof interpreted as almost flat roof creatively in accordance with the development plan (if it gets approved, feedback on this is also welcome)
What do you dislike and why?
- Sense of space, initially the house was planned as split-level but we were just afraid about aging difficulties; however, from our perspective, split-level offers a nicer spatial experience. Also, less earth would need to be moved, and the house would fit better to the terrain.
- Windows still need detailed planning
- The garage door is visible from outside
- Initially, an overhang of the upper floor above the terrace was planned, which might be more sensible
- Staircase should be smaller
- The plan is still very rough, this is only version 3
Price estimate by architect/planner: n/a
Personal price limit for house including fixtures: 770,000 (without plot)
Preferred heating system: heat pump (possibly brine/water system)

If you had to give up something, which features / expansions
- Could you do without: basically nothing, we want to implement all our requirements (you only build once). If really necessary, maybe the basement and thus the office on the ground floor
- Cannot do without: direct access from garage, ground-level access

Why is the design the way it is now? Talks with friends who have built (e.g., direct garage access)
Standard design from planner? No, individually planned by the architect
Which wishes were implemented by the architect? Ground-level access, room layout, modern house appearance
What makes it particularly good or bad in your opinion?
Good
- Modern and creative form (the neighborhood mainly consists of steep gable roofs, few hip roofs, and only one staggered shed roof)
Bad
- Previous design was split-level which would have created a more attractive house with better spatial feeling, but everyone advised against split-level and we are very skeptical as well and have ruled it out
What is the most important basic question about the floor plan, summarized in 130 characters?
What is your general feedback on the design? What is good/bad? What can be improved?
How do you see the chances of approval regarding the "distorted gable roof"/"capped split level"?

Best regards

I agree – it looks as if the house has been given a roof that’s too small.

I would really think twice about having two doors in the bathroom.
Also, consider the open space above. My in-laws have this, and when the kids were still living at home, it was almost impossible to sleep in the evening because the noise carried upwards strongly, especially when the parents were watching TV downstairs or having a game night at the dining table, for example.
The hallway on the ground floor just seems too long to me.
I hope the kitchen won’t be built like that. The passage above the island is maybe only about 80 cm (31.5 inches) wide.
I would also try furnishing the living room as planned to see how it works.

Otherwise, I think it’s great that the kids’ rooms are so spacious.

Still not good. Especially the upper floor. Many things simply don’t fit together. You want an extravagant house but then have a tiny bathroom. I would prefer it to be larger, and I would also remove the second door to the walk-in wardrobe, even though I understand the idea behind it.

The void above the living room would work much better, as it gives a sense of spaciousness. Above the dining table, it doesn’t make as much sense. However, that’s not possible with this floor plan.

The toilet as a narrow, small room next to the bathroom creates many angles and doors right next to each other.

The children’s rooms are nicely sized.

A huge improvement! Now it’s almost really cool.

The pseudo-roof is kind of funny. But whether it will look as good in reality as it does on paper remains to be seen. You might even get tempted to make it out of glass and open the rooms upstairs into the roof...

Above all, you need companies that are absolutely skilled. I think back with horror to our rogue builder as a cautionary example:
https://www.hausbau-forum.de/threads/grundrissplanung-kurz-vor-bauantragsstellung.25647/

I like the floor plan. The open space with the kids is something you’ll have to decide on yourselves, as it has been mentioned as problematic multiple times.
I don’t yet see the kitchen planning as perfect.

I still see issues with the windows. Too few or too small, especially here: bedroom, living area, bathroom, stairs.

The bathroom on the ground floor – is that supposed to be a shower? If yes, I would definitely enlarge it. Otherwise, it will be too tight. The wardrobe can be a bit smaller – you actually have two of them.

The basement should also be closely examined, especially its integration into the terrain (embankment, terrace, etc.).

I’m already looking forward to the pictures from the first groundbreaking.

I quite like it. How the roof will ultimately look is, of course, still exciting to see.

You might want to consider adding a door from the dressing room to the hallway and removing the "bathroom door" instead. This would create a bit more usable space in the dressing room, and you wouldn’t have to walk through the sleeping area when leaving.

I would also enlarge the guest toilet downstairs a little and make the wardrobe smaller instead, as the shower already looks very cramped.

I would never design an open void space like that with children. It may look great, but it’s very impractical and takes away the possibility of having a children’s bathroom and a nice, large, private master area on the upper floor.

How will the living room be furnished? You need to be careful that the distance to the TV isn’t too large. Are you familiar with the usual guidelines for this?
