Preface: The larger half on the north side (right on the plan) is intended for personal use. The smaller "half" on the south side (left on the plan) is for sale. For the sales half, the only requirement was a practical use of space for 3, max. 4 people. Therefore, I will go into more detail regarding the personal half.
Since this is not obvious from the floor plan excerpts: the personal half is 8.75 m (29 feet) wide and 9 m (30 feet) deep, the sales half is 6.10 m (20 feet) wide and 9.65 m (32 feet) deep (external dimensions).
Development Plan / Restrictions
Plot size: 479 sqm (5155 sq ft), 23 m (75 ft) wide, 20.80 m (68 ft) deep
Slope: sloping southwest, approx. 3 m (10 ft) across the northeast-southwest diagonal
Site coverage ratio: 0.35
Floor area ratio: 0.7
Building envelope, building line and boundary: 3 m (10 ft) setback line, no specific building envelope
Adjacent buildings: neighbors’ garage on the south boundary
Parking spaces: 2 per dwelling unit
Number of floors: 2 full floors
Roof type: pitched roof 25-45 degrees, exposed rafters, half-hipped roof, vented ridge
Maximum heights / limits: max. ridge height 9.50 m (31 ft)
Additional requirements: none
Client Requirements
Style, roof type, building type: modern, clean lines, simple building form, gable roof
Basement, floors: no basement, 2 full floors plus attic
Number of occupants, ages: 3 (2 adults + baby, no more expected); the second semi-detached unit should accommodate a family with up to 2 children
Space requirements on ground and upper floors for own half:
Ground floor: guest WC, wardrobe, large open living/dining area, open kitchen, utility/technical room
First floor: large children’s room, master bedroom, family bathroom, laundry room
Attic: studio (office / guest room / hobby room), shower room
Office: both family use and home office
Guests per year: approx. 20 nights, 1–4 people
Open or closed architecture:
Conservative or modern design: modern
Open kitchen, cooking island: both
Number of seats at dining table: 8
Fireplace: undecided
Sound/music wall: no
Balcony, roof terrace: no
Garage, carport: no, parking spaces only
Kitchen garden, greenhouse: no
Other wishes / special features / daily routines and reasons why some things should be included or excluded: For the personal half, there was a requirement for a half-landing staircase that is not accessible from the living area. A design away from the “classic semi-detached house standard” was desired, including externally. No “entrance corridor”.
House Design
Designed by: architect
What do you particularly like? Why?
Personal half:
- Split level to the living area, creating high ceilings in the open living space and making use of the topography
- large wardrobe/coat area
- storage space utilized under the staircase
- utility room on the first floor
- large children’s room (intended to be swapped with the attic studio when the child is older)
Sales half:
- ?
What do you dislike? Why?
Personal half:
- Utility room only accessible from outside (wtf?!)
- Open living space rather small
- Kitchen is small, no island, dining area only for 6 people
- Guest WC wastes space
- Overall few and small windows
- Family bathroom layout: shower exit directly in front of the door, toilet right next to the sink
- No dressing room
- Attic bathroom: again, shower exit directly in front of the door
- Attic studio windows: tiny arrow slit window facing west (the side with the really great view) and two roof windows. (my next wtf moment)
Sales half:
- No second shower bathroom
- First floor bathroom tiny, no shower
- Boring floor plan
- Second room in attic without a window?! (again a wtf moment)
Price estimate according to planner: just within budget (prefer not to discuss figures publicly due to sales plans, thanks for understanding)
Preferred heating system: ideally geothermal, if still within budget
If you have to give up something, which details/extras
- can you do without: geothermal heating, attic bathroom (would at first only install plumbing, finish later)
- can you not do without: half-landing staircase
Why is the design as it currently is?
Our requirements regarding the space program were largely implemented.
Which requests did the architect fulfill?
Offset in height and depth between the two halves, staircase not opening off the living room, utility room on the first floor
What do you consider especially good or bad?
The arrangement, location and size of the windows raise major questions for me.
Furthermore, I don’t understand why the plot width isn’t fully used. We are fine with 3.50 m (11.5 ft) on the sides for parking. For the sales half, we’d leave 3 m (10 ft) to preserve garden space at the back. The very first study was even more “tube-shaped,” and we already pointed that out. Now the northern half still has 4.12 m (13.5 ft) and the southern 3.93 m (13 ft) width on the sides. Why?? Dead space next to the cars that we won’t use, instead of garden space facing west.
What is the most important/basic question about the floor plan in 130 characters?
What can we do better?

So, here is the complete version. It should be noted that this is still the design phase, so some parts have been put together quickly, and the exterior views for House 2 (for sale) are not yet final.
In the upstairs bathroom of House 1 (north half), there will be a storage nook on the right side of the plan, and the shower will be moved next to the door. Access to the storage nook will be between the bathtub and the shower, where a washer/dryer stack and shelves for towels, cleaning supplies, toilet paper, etc. will be placed.
The dining table on the ground floor is not yet properly sized; it will be a table for 8–10 people. We will probably prepare for a fireplace connection, which would be positioned slightly elevated on the split-level steps between the dining area and seating corner.

Yes, I noticed that too. I was thinking of shifting the wall between the kids’ rooms slightly to the right according to the plan,I would leave it as is. Some rooms simply have only about 2.40m (7 ft 10 in)... in this case a bit more. Maybe it will become an office?!

The wastewater drainage in the attic would worry me. Does it run through the bedroom? I would consider swapping the heating and the second shower.I wouldn’t see that as a problem either. The alternative with the swap is not ideal since the sloped ceilings get in the way.
It’s all one family living in the house, so I wouldn’t worry too much about noise issues.
What I would improve if it were mine: I would place the tall kitchen cabinets where the terrace door is, aiming for an L-shaped kitchen. Then move the island to the center wall of the house, so further to the right according to the plan. Where the island was attached before, put the terrace door. So everything would rotate within this triangle. The terrace door where it is now only causes issues when it’s open.
Here are the preliminary views "quickly done," meaning some of the windows are not entirely accurate and with the following changes:
The carport for House 1 (light) will be applied for, but we probably won’t build it at first. I don’t like it... The storage room might be made slightly larger instead. The front door will definitely not be glass, as incorrectly shown here.
House 2 (dark) will not have a garage, but a storage room instead, possibly with a carport. It fits better there.
That is why there are windows and a patio door from the kitchen on that side at ground floor level.

Then position the island along the house’s central wall, so more to the right of the plan. Where the island was previously attached would become the patio door. So everything rotates around this triangle. The patio door in its current place only gets in the way when open.Are you referring to the southern half? I ask because I just posted the complete project. I need to think it through, but it sounds good at first.
I’m still not happy with having the kitchen in the northern half; I doubt I can fit everything I want there.
