Hello dear forum visitors and experts,

after countless plans, we now have a final version which I kindly ask you to review for any design errors. Nothing is set in stone yet, and I am very happy to hear your comments.
- The ground floor (GF) looks very good to us. Unfortunately, the first floor (FF) is not quite there yet.
- Important: roof slopes are not yet accounted for in the software.
- Dimensions in the floor plan are in meters.

The main questions are as follows:
  • Does the floor plan contain any major design errors?
  • Is the main entrance well positioned? (currently planned on the east side)
  • Is the staircase sensible? (we have also seen good floor plans with a central staircase)
  • Is there perhaps a trick to gain a bit more knee wall height for the first floor without sacrificing a ceiling height of approximately 2.60m (8 ft 6 in) on the ground floor? Do you think 2.60m is excessive? We mostly spend time on the ground floor in the dining and living areas.
  • The first floor study room is too large. Bedroom is somewhat too small, bathroom a bit too small, storage room feels somewhat “in the way.”

Attached are hopefully all relevant details about the floor plan/plot as well as the development plan.

Development plan / restrictions
Plot size: 520 m² (5600 sq ft)
Slope: none
Floor area ratio (FAR): 0.25
Floor space index (FSI): 0.4
Building envelope, building line and boundary: 12 x 10 m (39 x 33 ft) perimeter development
Number of parking spaces: 2 cars
Number of stories: 2
Roof type: gable roof, 38–42 degrees
Architectural style: modern with large glass fronts
Orientation: length of the building east-west
Maximum height / limits: 3.9 m (12 ft 10 in) exterior wall height (insulation above rafters)
Additional requirements: Building footprint ratio 1.0 m width to 1.2 m length

Owners’ requirements
Style, roof type, building type: modern, large glass fronts, gable roof
Basement, floors: basement planned, 2 floors
Number of occupants, age: 2 persons, 31 & 32 years old
Space requirements GF / FF: large open living area, family use or home office? Home office desired on the first floor
Guest overnight stays per year: few
Open or closed architecture: open
Conservative or modern construction: modern, not a KFW house
Open kitchen, kitchen island: closed kitchen with large sliding door, kitchen island would be “nice to have” but not essential
Number of dining places: 1
Fireplace: yes, a MUST!
Music / stereo wall: no
Balcony, roof terrace: no, no
Garage, carport: doesn’t matter, for 2 vehicles
Utility garden, greenhouse: utility garden
Special features: very sunny location, distant view to the north side

House design
Who designed the plan: layperson (ourselves) – DIY

What do you particularly like? Why? Ground floor, large and open living area including fireplace
What do you dislike? Why? Little storage space on the ground floor, low knee wall on the first floor
Price estimate according to architect/planner: not yet available, but should fit within our budget
Personal price limit for house including equipment: 520,000 + 100,000 basement
Preferred heating technology: no connections, therefore external energy supply

If you had to give up something, which details or expansions?
-can you give up: house entrance location, basement, other
-can you not give up: high door frames, fireplace, large window fronts (on the north & west sides on the ground floor), open living area, bedroom on the northwest side

Why is the design as it is now?

What do you consider especially good or bad about it?

Good: open living area (ground floor)
Bad: feels like too little storage on the ground floor, no pantry

As mentioned in the original post, we have the inconvenient requirement that the building structure must have a length of 1.2 meters (4 feet) per meter of width.

And what does that have to do with the rotation?

Ah, yes. I’m reading. And the building envelope for the garage is different from the one for the house... and the one for the house is coincidentally 12 x 10 meters (39 x 33 feet)? I find that hard to believe. I would like to clearly separate what is the official requirement and what is your interpretation or instruction for us. Otherwise, your options are very, very limited.

Is it possible to look up the zoning plan online?

I'll put it this way: if the plot is 520 m² (5600 ft²), then you can build a house covering 130 m² (1400 ft²). However, you mentioned dimensions of 12 x 10 m (39 x 33 ft).
Then the floor area ratio of 0.25 and the plot ratio of 0.4 contradict the two-story design.

I would like to plan based on the actual facts and not on incorrectly transferred information… no offense intended…

With an external dimension of 6.0 meters (19.7 feet) for the garage, you can optimistically expect an internal clear dimension of about 5.60 meters (18.4 feet). This will definitely not be enough to arrange both cars and the two motorcycles. You also need to plan for a passageway.

This is just “at first glance.”

Good luck

This is usually understood as the minimum deviation from a square, meaning a clearly defined "building axis" is desired, often combined with a ridge direction requirement.

Do you really need such a large office upstairs?
I would always place the utility room for laundry upstairs; without a children’s room, you have enough space for that.

You are both still very young. Are you 100% sure that you won’t have children?
Otherwise, I would design the (large) office so that it could potentially be divided into two rooms (either two children’s rooms or one children’s room and an office). That’s not possible here because there is only one door.

For a house for a couple, I wouldn’t want to do without a walk-in closet. Better to have a smaller bedroom (just big enough for the bed) and a separate dressing room.

The kitchen layout doesn’t work. It’s not ergonomic and there is far too little storage space for its size.

Storage space is lacking on all floors overall. You won’t want to run down to the basement for every little thing. Think about that...
