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
Karina

Yes, the plan is oriented to the north.
We chose the roof direction so that the roof surface faces south, allowing us to position the photovoltaic system optimally there.

The access road is on the right, exactly.

But that doesn't match the windows and so on at all. And the gallery window would have a maximum knee wall height minus the lintel. You wouldn't have anything of that left in the upper floor hallway.
Or am I just having a mental block right now?

The north arrow is probably placed incorrectly.

The upper floor is 9.42 meters (31 feet) deep, while the ground floor is only 9.00 meters (30 feet), according to the wall dimension on the left.

No, kbt09 is right about the orientation (and was quicker and smarter than me with rotating it). We would plan a gable for the gallery window. The Weberhaus show home in Wenden with the staggered shed roof illustrates this quite well.

Then I notice: one external wall measures 7 meters (23 feet), including the exterior walls at the corners. At 6.20 meters (20 feet 4 inches), there is an internal wall. So 6 meters (20 feet) remain to be divided between the living room and the office. Hmm...

I would like to point out again that this needs to be taken into account. A program is being used here, and like many others, the delete key is no longer pressed.
Next time, use graph paper, so you can keep an overview of the width of the living room as well.
