kklk18Hello 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

[...] Number of floors: 1.5
Roof style: mono-pitched roof I don’t see much matching here. I don’t understand why the bathroom is excluded from the floor area ratio calculation.

It feels like wasted space because it’s really only intended as a corridor/hallway to access the rooms Still, nobody likes to feel like a mail tube when moving from one room to another. I can’t quite reconcile saving on gallery and hallway space.

11ant, first of all, thank you for your reply.
Oh dear, that doesn’t sound very promising at first.
The reason for the gallery is that we would like to have a large window spanning two floors as a highlight of the house.
Maybe a quick clarification regarding the development plan from 1984 -> old land use ordinance:
Site coverage ratio: 0.2 -> 500 * 0.2 = 100
Floor area ratio: 0.3 -> 500 * 0.3 = 150
The building height of 1.5 means exactly: one full floor plus a finished attic.
A house with a shed roof would fit within the development plan; a few plots away (same development plan) there is a house similar to our wishes.
The exclusion of the bathroom and the open space from the floor area ratio results from the statement of the official at the building authority, where we already inquired.
The bathroom, which is not located in a full story, is—according to the legal situation at that time—not considered a habitable room and is therefore excluded from the floor area ratio (which is based on the external dimensions). The same probably applies to the walk-in closet (as it is a storage room).
I hope this helps clarify things a bit.

Obstlerbaum21 Sep 2018 22:09Was a semi-detached house mentioned in the opening post? Anyway: bathroom facing southwest, but the child only gets a few minutes of morning sun during the height of summer? If it is not a semi-detached house, the situation is even more problematic...

If it is not a semi-detached house, the situation becomes even more critical...No, it is a detached single-family house, not a semi-detached one.
I have corrected the north orientation on the site plan, I made a mistake there, sorry.
The updated files have been uploaded in the original post.
The children’s rooms face south and west, the bathroom and master bedroom face north.
The budget and the house do not match.
Try to design four straight exterior walls.
The house is too small for a straight staircase and gallery.
There is a lack of storage space—except for the oversized walk-in closet.
Where is the wardrobe for 5 people?
The utility room/technical room/storage room is too small.
Have you tried arranging furniture in the kitchen?
Remove the door between the utility room and kitchen. It takes up valuable space in the utility room. The kitchen should have a door leading to the hallway.
The staircase looks very small.
Upper floor
The walk-in closet is almost as large as the children's rooms.
Have you already drawn in the bathtub, shower, toilet, and sink in the bathroom? A proper cabinet should also fit for towels and hygiene items for 5 people.
The hallway and gallery take up too much space. The two small children’s rooms could benefit from a bit more room.
What will happen to the bay window area for dining on the upper floor?
Please draw a proper furniture layout in all rooms to scale.
