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’m not an expert on development plans, but if the "cap" is approved (which in this case would be a shed roof), then I don’t understand why all of Germany complains about picky building authorities.

Taste is, of course, a very individual matter... I believe most architects would refuse to design something like this. I personally wouldn’t like it at all. If anything, I would extend this shed roof across the entire width. That way, you would have a shed roof/flat roof combination, which would probably comply better with regulations without completely destroying the cube style.

Regarding the floor plans... I only looked at them briefly. At first glance, I noticed that the walk-in closet and bathroom dimensions are a disaster. Is the walk-in closet 1.60 m (5 feet 3 inches)? Rough construction measurement? 60 cm (24 inches) for a wardrobe, 30 cm (12 inches) for shelving? That leaves 70 cm (28 inches) of width in between? Possibly even less when accounting for plaster, etc.?

Same goes for the bathroom. Are you not fond of being in the bathroom? A narrow corridor with two doors. Calculate the distance between the sink and the shower. Of course, everyone has different needs and priorities, but if someone were to build like this, I would expect a different bathroom. This one has more the feel of a wet room.

The ground floor looks pretty good at first glance. I find the location of the staircase a bit out of the way, but that has already been mentioned.

I also find the small gable roof quite odd. Even if it actually gets approved by the authorities, it still looks unattractive. Sorry, I can’t think of a better word for it.
I would have been happy to have a staggered shed roof. That was my wish for our house, but only gable roofs were allowed.
I also have quite a few thoughts about the floor plan. I’ll write about those later.

The roof reminds me of the house recently discussed here. Designed for two people, with a huge gallery and everything else oversized, but the overall building form is completely botched.

Planners and builders get tunnel vision when trying to cut corners on the zoning plan for aesthetic reasons, but fail to see how they ruin the house.

And without improvements to the bathroom and dressing room, there's no point in continuing with the floor plan either.

The roof is really scary!

Yes, it is. I would never have such a "cap" installed on my roof. I also don’t think something like that would get approved.

One can only hope.

Sorry, but I think you might have gotten a bit carried away with the desire for a flat roof...
