Development Plan / Restrictions
Plot size: 610 sqm (about 15 x 40 m) rectangular
Slope: East-facing slope, approximately 28% gradient. Road downhill. The house is planned to be positioned in the upper third on the hill side (for privacy and view).
Floor area ratio: n.a. (no development plan)
Plot ratio: n.a.
Building window, building line and boundary: n.a.
Setbacks: presumably 2.50 meters (8 feet 2 inches) in all directions
Number of parking spaces: n.a.
Number of floors: n.a.
Roof type: n.a.
Architectural style: n.a.
Orientation: n.a.
Maximum heights / limits: n.a.
Other requirements: There is no formal development plan. However, the street features a variety of house types, so almost any architectural style should be possible.
Client Requirements
Architectural style, roof type, building type: Bauhaus style, preferred flat roof (possibly also shed roof)
Basement, floors: Basement integrated as a living space in the slope, with two floors above
Number of occupants, ages: Currently 3 persons, aged 33, 32, and an infant
Space requirements on ground floor (GF), upper floor (UF):
GF: kitchen, pantry with sink niche, living room, study, WC, entrance area with dressing room
UF: master bedroom with dressing room, two children’s rooms, bathroom, roof terrace
Basement: guest room, guest bathroom, study, laundry room, technical room, storage room, fitness room
Office: currently family use, potential home office in future
Overnight guests per year: parents-in-law visit frequently
Open or enclosed layout: open
Traditional or modern construction: modern
Open kitchen, kitchen island: open kitchen with island
Number of dining seats: one large dining table
Fireplace: preferred, as shown in the floor plan
Music/speaker wall: possibly in the living room
Balcony, roof terrace: roof terrace facing the valley (east side)
Garage, carport: double garage detached from the house, cut into the slope at the street
Utility garden, greenhouse: no
Other wishes / special features / daily routine, including reasons why something should or should not be: no ventilation system, no smart home, photovoltaic system
House Design
Who designed it: do-it-yourself
Living area: approx. 230 sqm (including half the roof terrace area)
Usable area: approx. 260 sqm
What do you like most and why? The overhangs to the east and south, the glass facades, the integration into the slope, the straight staircase, the long visual axis on the ground floor
What do you like least and why? Possibly the entrance area as it may be too small; living room may be too small
Estimated cost according to architect/designer: not available yet
Personal budget for house including equipment: n.a.
Preferred heating technology: air-to-water heat pump, underfloor heating
If you have to compromise, on which details / extensions
- which can you do without: overhangs if much more expensive, flat roof if much more expensive
- which you cannot give up: glass facades
Why is the design as it is now?
The floor plans are a first draft, completely self-developed, and intended as a starting point for discussion. The design is based on three main principles: slope orientation, cardinal directions, and plot shape. Because of the east-facing slope, the larger floor-to-ceiling glass facades and living and dining rooms on the ground floor, as well as the guest room in the basement, are positioned facing east (offering a nice view of the valley). To allow access to the outside from the kitchen and take advantage of sunlight, the kitchen on the ground floor is adjacent on the south side, also with large glass facades. Another idea was to create a long line of sight to the valley directly upon entering the house, which is why the entrance is positioned on the uphill side. Functional rooms (bathrooms, technical room, dressing room, pantry, etc.) are generally oriented uphill (to the west). All WCs are stacked to simplify plumbing. The two 1-meter (3 feet 3 inches) cantilevers are mainly aesthetic but also provide some shading and would be dispensable if needed. The original shape was a simple 10 x 10 m (33 x 33 feet) cube, but this version is preferred by my wife and me. The glass facades are not yet fixed in size and serve as rough guidelines; they could be slightly smaller if structural requirements demand it. The straight staircase may be a point of discussion, although I personally find it very appealing visually.
Regarding privacy and neighbors: downhill side is not relevant due to the slope. On the uphill side a neighboring house is adjacent, so no open facades are planned there. On the north and south sides, houses are located further up the street, with tall trees and shrubs in between. This provides almost complete privacy.
Please ignore the outdoor areas not attached to terraces in the floor plans, as these were only used for rough simulation of the slope.
What is the key question about the floor plan, summarized in 130 characters?
Is our design heading in the right direction, or are there major issues we have overlooked?
The plan is also intended to obtain initial cost comparisons from various companies for a similar house. We understand that an architect will need to be involved in further planning.
We are grateful for any feedback!

I found the project by @matte very interesting back then. Also on a slope, although not nearly as steep as yours, @RoterPapagei... I just did a bit of digging.
Matte summarized and commented on his initial attempts [here] and then posted his final version in the follow-up post [here]. Maybe you can gain some insights for your own project.

Nice-Nofret26 Aug 2022 11:11With the steep slope, it should be considered whether a terraced house design (where each floor is staggered) might be more cost-effective. The earthworks, excavation, and the required retaining walls will be very expensive with this plan.

I think we would prefer not to spend more than 1 million on the house. Is that specific enough? Sorry for the basic question, but do you mean just the house or the house including additional costs and the modeled plot and garage? In your case, there could easily be a difference of well over 200k. Do you have a soil survey or at least some rough idea from neighbors about the ground conditions? Because if there is any rotten rock present, all your cost estimates for excavation could be seriously off. Is a pool something you are considering?
Are there only hedges/shrubs in the south, or tall trees that block all the light?
The current plan still has proportional issues, but many of your wishes can be seen, such as a pantry, dressing room, separation between laundry room and technical room. I would also recommend reconsidering the design.
