Hello everyone,
I am new to the forum, but have been following along for a while and have already gathered quite a bit of knowledge.
Attached are the floor plans for the ground floor and upper floor of a single-family house; I know the dimensions do not yet match the floor area ratio, this is just an initial rough sketch that I plan to refine step by step.
Here are the details:
Development Plan / Restrictions
Plot size: 500sqm (5400 sq ft), rear plot
Slope: No
Site coverage ratio: 0.2 → 100sqm (1076 sq ft)
Floor area ratio: 0.3 → 150sqm (1615 sq ft) excluding the bathroom on the upper floor
Building envelope, building line and boundary: only 3m (10 ft) distance to the boundary must be maintained
Edge development
Number of parking spaces: 2
Number of floors: 1.5
Roof type: single-pitch roof
Architectural style: modern
Orientation: southwest
Maximum heights / limits: eaves height max. 4.5m (15 ft)
Additional requirements: old development plan → bathroom upstairs and air space are not included in the floor area ratio; likewise, no sealed surfaces outside the building
Homeowners’ Requirements
Style, roof type, building type: solid construction, rather modern style, large windows
Basement, floors: no basement, 1.5 floors
Number of occupants, age: 2 adults, 1 child (3 planned in total)
Room requirements on ground floor and upper floor: see floor plan
Office: family use or home office? Home office 2-3 days per week
Overnight guests per year: 10
Open or closed architecture: open
Conservative or modern construction: modern
Open kitchen, kitchen island: kitchen directly connected to the dining room via sliding door
Number of dining seats: 6
Fireplace: yes
Music / stereo wall: no
Balcony, roof terrace: no
Garage, carport: double carport → 2 parking spaces as mentioned above
Utility garden, greenhouse: no
Other wishes / special features / daily routine, also reasons why certain things should or should not be included: gallery window from ground floor to upper floor → I know galleries are not very popular here, but we like this very much
House Design
Who planned it: self-designed using building brochures and impressions from friends’ houses as well as show homes
What do you like most? Why? Open living area; the heart of life and a meeting point; central stringer staircase
What do you not like? Why? Corridor size on upper floor; it feels like wasted space as it is really just a hallway leading to the rooms
Estimated cost according to architect/designer: still open
Personal price limit for the house including equipment: 270,000 EUR (without electrical, heating, sanitary, and outdoor facilities) → land already deducted. We are building in northwest Germany
Preferred heating technology: heat pump
If you have to give up, which details or extensions
-can you give up:
-can you not give up: size of the walk-in closet due to the size of Ikea Pax wardrobes, gallery window, shower in the ground floor bathroom, external blinds on the ground floor
Why did the design end up the way it is?
A mix of many examples from various magazines...
What is the most important / fundamental question about the floor plan summarized in 130 characters?
I’m looking forward to your opinions and would appreciate suggestions for improvement J
For now, I have left out the windows, as we are still at the very beginning and it is only about the spatial layout...
Thanks in advance for your help and best regards

But you wouldn’t add a highlight if the rooms below have to suffer because of it.You are basically right. However, if we couldn’t subtract the gallery space, the floor area ratio would be even higher. Currently, we have 157 m² (1,689 sq ft) according to the calculation method valid at the time. Without the open space, it would be 161 m² (1,734 sq ft).
Do you see what I mean?
It’s definitely a tricky challenge, but that’s why I’m here.
With an eaves height of 4.50 meters (14 ft 9 in), you can build a gable roof house with a knee wall of about 120-140 centimeters (47-55 inches), featuring a gable roof that does not reach two full stories. A floor area ratio of 0.3 allows for a total house size of 150 square meters (1,615 square feet). As far as I know, this includes all rooms inside the house, including technical rooms and storage rooms.
The calculation of living space is a different matter, as storage rooms are not included there. To my knowledge, these are two separate concepts.

Can you clarify this before there is speculation based on incorrect assumptions?

If the ground floor has a ceiling height of 2.6 m (8.5 ft), and you subtract the intermediate ceiling (0.5 m (1.6 ft)?), this results in a knee wall height of 1.4 m (4.6 ft), right?If you want a room height of 260 cm (8.5 ft), the floor-to-floor height will be about 290 to just under 300 cm (9.5 to 9.8 ft).
I found this image:
125 cm (4.1 ft) on the far right, with a floor-to-floor height of 285 cm (9.4 ft) and a finished floor level 40 cm (16 in) above the zero reference point.
I can’t be more specific than that right now; you just have to take these things into account. That’s why the 2 m (6.6 ft) line also needs to be considered.
And, of course, considerations about which windows to use.

However, Section 20 (2) of the 1977 Land Use Ordinance applies. It states:
(2) The floor area is to be determined based on the exterior dimensions of the building on all full floors. The areas of habitable rooms on other floors, including the associated stairwells and their enclosing walls, must be included.
Since bathrooms and storage rooms are not considered habitable rooms under the regional building code, they must be deducted accordingly. This is consistent with the statement from the building authority. Otherwise, we would likely exceed the 150 sqm (1,615 sq ft) limit.
The rule about “less than X ceiling height” does not apply here. It really comes down to the exterior dimensions of the ground floor (1 full story) plus the rooms above.
Or put differently: exterior dimensions of the ground floor multiplied by 2, minus bathrooms, storage rooms upstairs, and open spaces.
It’s quite complicated and has been handled completely differently since 1990.
I just did a quick search to find a good example, especially regarding the windows for reference.
The display home by Weberhaus in Wenden is roughly the style we are aiming for. However, without a balcony. The gallery window would then be placed in the gable. And, of course, smaller.

Alright, then go ahead and draw your roof… the Weberhaus doesn’t have skylights, it has the bay window, and so on. Your children’s rooms will all be lit by skylights. You’ll need to consider the height of the knee wall. Otherwise, you’ll also need knee wall skylights so the kids can actually look outside, at least as long as they are under 150 cm (5 feet) tall.
