Development Plan / Restrictions
Plot size: 440 m² (4,736 ft²)
Slope: steep slope of 30° - 40° in the rear area, 7-10 m (23-33 ft) towel-shaped plateau along the street
Floor area ratio: not applicable, suitable
Gross floor area ratio: not applicable, suitable
Building envelope, building line, and boundary: no zoning plan, building permit for another project already approved
Edge development: single-family house, 2 full stories, mostly gable roof, but also flat and hipped roofs
Number of parking spaces: 2 required (no trapped parking space)
Number of stories: 2 full stories plus partial basement on the south-facing slope
Roof type: gable roof
Design style: open to planning
Orientation: hillside facing southwest
Maximum heights / limits: unknown
Other requirements: no zoning plan
Owners’ Requirements
Style, roof type, building type: gable roof, timeless both inside and out
Basement, stories: partial basement (on the slope) + 2 full stories (see cross-section)
Number of people, ages: 2 adults + 2 children
Space needed on ground and upper floor: approx. 85 m² (915 ft²) per floor
Office: initially none, if needed in guest room or basement
Overnight guests per year: hopefully many 🙂
Open or closed architecture: compromise, as the two apartments should remain separable in old age on ground and upper floor
Conservative or modern construction: as above
Open kitchen, kitchen island: yes
Number of dining seats: minimum 4
Fireplace: yes, in the conservatory
Balcony, roof terrace: yes, on the basement level, 2.5 m (8 ft) facing south
Garage, carport: yes, on the east side by the main entrance
Utility garden, greenhouse: terraced garden planned with usable areas
Other wishes / special features: no water connection in the basement to avoid a lifting system. Therefore, laundry room in the upper floor instead of basement. It is located by the stairwell so it can still be used in old age when the upper-floor apartment is separated by a door.
House Design
Who designed it:
Planner from a construction company together with us
What is especially liked? Why?
Open floor plan on the ground floor combined with private retreat areas on each floor. Bay window facing south (downhill side), conservatory, and terrace there as well
What is disliked? Why?
Basement and shape of the basement are not entirely satisfactory but likely cannot be changed due to staircase position in the stairwell.
WC and room on the ground floor feel cramped; have not found a better solution as access should not be through the main hallway
Cost estimate: none yet
Personal price limit including fittings: as long as we stay under 5 million, everything is fine 😀
Preferred heating system: solar combined with pellet heating
What you could live without
-could live without:
Upper floor bathroom is still very large; could be smaller
-cannot live without:
Ability to separate living units for old age, bay window in the living room
Why is the design like this?
The plot has a towel-shaped plateau measuring 22 m (72 ft) wide and 7-10 m (23-33 ft) long. The house’s mass will be placed there. A seating area/garden is planned to the west with access from the kitchen via a few meters of wooden terrace. The slope on the south side drops steeply. The garage and a parking space at the driveway will be located on the east side.
Windows are positioned symmetrically from the outside perspective, which is why their arrangement on the ground and upper floor appears a little unusual.
What is the most important/fundamental question about the floor plan in 130 characters?
We want to use the plot as it is, not fight against it. The unobstructed south view should be emphasized. The sightline from the entrance through the hallway, glass door over the dining table to the garden in the west should make the house feel spacious. Three old trees on the plot will be integrated into the garden. Inside, we aim for minimalism and a timeless living feel.
We welcome all suggestions and ideas but also have clear concepts that can hopefully already be seen in the floor plan.
Is there anything you think we should consider or improve?
Thank you very much for your support 🙂

What exactly? A simple list or something similar would be helpful. Is this question really serious? You’ve been active here for half a year already.
The "highlight" is the sleeping area.
In general, and especially the upper floor: you simply can’t fit the number of rooms sensibly into those few square meters (sqm (square feet))—as you can (actually) easily see. 🙄

The “highlight” is sleeping. This is the guest bedroom...
What should be separated later and under what conditions?
If the parents sleep there, they get access to the garden.
Living area gets the terrace.
That actually doesn’t make much sense.
What is the purpose of the conservatory?
How is it accessed on the upper floor, or is it open?
Please draw the desired furniture layout on the ground floor to scale. The dining area seems much too small, plus there is wasted space between the dining and kitchen areas.
There is no wardrobe/coatroom on the ground floor.

What will be separated later and under what conditions?The upper floor will be separated as a granny flat once the children have moved out. For that, a drywall partition will be installed at the north entrance, and that’s it. Then the apartment upstairs will be independent. haydee schrieb:
Sleeping area for parents gets garden access
Living area gets the terrace
That actually doesn’t make much sense Why not? The area south of the parents’ sleeping zone slopes steeply downward at about 30°–40°, so it’s more of a utility garden than anything else... haydee schrieb:
What is the winter garden for?
How is it accessible from the upper floor or is it open? It is not accessible upstairs; it is an open void. haydee schrieb:
The dining area seems way too small, and there’s wasted space between dining and kitchen The dining table measures 1.4m by 1.2m (4.6 ft by 3.9 ft), and that space isn’t wasted, it’s just open and unfurnished freedom :p haydee schrieb:
There is no cloakroom on the ground floor In my first post about the new floor plan, I tried to explain that at the east entrance there will be either a storage room or a cloakroom. Most likely a cloakroom, but unfortunately not both…The drawn table is not 1.2 x 1.4 meters. The minimum space required for these dimensions is 2.8 x 3 meters. However, no one can comfortably walk past when the chairs are occupied.
Is there flexibility in that area?
Which entrance will be your main entrance? That’s where coats and shoes should be stored.
How old are your children?
Are you already planning the technical installations for two separate living units?
