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

Can you clarify this before people start making incorrect assumptions? The original poster already did, I confirm:

Since bathrooms and storage rooms are not considered habitable rooms according to the building code, they must be excluded accordingly. So: Gross floor area = full stories + habitable rooms in non-full stories + circulation areas for habitable rooms in non-full stories (stairs and corridors), all measured from external dimensions.
If the floor plan is optimized (don’t forget the 1m, 2m, 2.3m lines), please highlight it again, then I will recalculate when I have time.
Hello everyone,
Yesterday was my offline day, so I’m only responding today.
We actually designed the floor plan the traditional way, on paper with a pencil, countless erasures, and graph paper. However, we used a wall thickness of 0.5mm (about 0.02 inches) there since it was just for the sketch. Afterwards, we transferred it into the software to include the thickness of the external and internal walls. The roof cannot be represented there, which is why there is no 3D view.
We will adjust the proposal again based on your tips. Regarding the utility room: the fact that you might directly face a wall there doesn’t bother us. It’s a room that is used only once or twice a day and isn’t meant to be representative.
Our further consideration was to place the technical installations outside the house, behind the carport. A friend of ours has done this in his single-family home. This way, we could save on floor area ratio and gross floor area.

Regarding the utility room: we don’t mind that it faces the wall directly, for example.But then you can’t pull out a ladder, set up an open drying rack, or struggle with shopping bags along a barrier. When planning a house costing around 250,000 or more, that is unnecessary hassle that also adds to costs.

Another consideration was placing the technical equipment outside the house, behind the carport. An acquaintance has done this in their single-family home. This would save on site coverage ratio and floor space index.Mechanical and electrical systems need to be within the thermal envelope. How old is your acquaintance’s house?

This way, we would save on the floor area ratio and the number of floors ratio. The term "technical equipment" is a bit vague—what exactly do you mean to move out of the house?
The heating system, main utility connection, and power storage. The external room would also be built with masonry and properly insulated. However, it wouldn’t count towards the floor space ratio because it is not considered part of the main house (according to our land use regulations, only the main house is relevant). Or am I missing something here?
