Hello everyone,

we have purchased a quite challenging sloped plot and have now received the first draft from our architect. I have personally revised it to address some weaknesses that arose due to my requested changes. The exterior dimensions are relatively fixed. I am fairly satisfied but would appreciate some additional feedback before sending it back to the architect.

Development Plan/Restrictions
Plot size: 731 sqm (7870 sq ft)
Slope: Yes, steep slope; the street runs north down into the valley and the garden is elevated on the mountain to the east
Building envelope, building line and boundaries: 3 m (10 feet) to neighbors/street
Orientation: Garden east, street west
Maximum heights/limits: still uncertain. According to the preliminary building inquiry, about 9.50 m (31 feet) from basement slab
Other requirements: according to § 34

Client Requirements
Style, roof type, building type: Modern, flat roof
Basement, floors: Basement plus 2 full floors
Number of occupants, ages: 4 persons (41 years, 29 years, 3 years, 1 year), possible third child later
Space needs on ground floor: Living-dining-cooking area, storage/pantry, guest WC, office
Space needs on upper floor: Bedroom, dressing room, master bathroom, utility room, 2 children’s bedrooms, children’s bathroom
Space needs in basement: Secondary apartment as office and fitness area, technical room, entrance/wardrobe, storage, technical room, garage
Office: Family use or home office? 2 home office rooms
Overnight guests per year: 2 weeks per year
Open or closed layout: Very open living-dining-kitchen area; rest more closed
Conservative or modern construction: ?
Open kitchen, kitchen island: both desired
Number of dining seats: 8-10
Fireplace: rather no
Music/sound wall: if possible
Balcony, roof terrace: no
Garage, carport: Large garage with double door
Utility garden, greenhouse: no
Additional wishes/special features/daily routine, also reasons why something should or should not be included: very different daily rhythms, husband goes to bed late and sleeps accordingly long. Basement office for undisturbed work.
We would like the garden level to be as high as possible above street level since the plot borders a nice meadow that is currently about 1-2 m (3-6 feet) above garden level. However, the house cannot be set too high because otherwise the garage entrance would become too steep.

House Design
Planner: Architect, with interior adjustments by myself
What do you particularly like? Why? Open, spacious living area, bay window
What do you dislike? Why? Unfavorable cloakroom situation when arriving from the garage. Long dirt zone through which you have to pass to reach the office.
Price estimate by architect: over 1 million
Personal price limit for house, including features: basically already stretched at 1 million, possibly up to 1.1-1.2 million
Preferred heating technology: Heat pump, underfloor heating

If you have to give up something, which details/extensions
- Can you give up: Installation of the basement office as a separate apartment, but desired for tax reasons
- Cannot give up: Basically everything is in some way desired/important

Why does the design look the way it does? For example:
Due to the challenging slope of the plot, many factors are more or less predetermined. There was already an approved building application from another architect, which independently resembles this design closely.
I fell in love with the kitchen bay window in a show home, which unfortunately means the pantry cannot be used as the direct extension of the kitchen as originally planned... Since the kitchen is very large, the room will probably function more as a storage pantry.
On the upper floor, the second children’s bedroom is located in the northwest rather than the southwest because the higher neighbor's house stands directly to the south, and to the north there is a great view of the green valley.

Thank you very much for your design. Unfortunately, it doesn’t quite suit us. The bedroom can’t be on the ground floor because my husband sleeps until noon, and then we couldn’t be loud in the living area. But I’m currently working on another stair design myself and will definitely use yours as inspiration.

Then it’s best to put your bedroom in the basement level, because otherwise you’d have to forbid the children from playing in their rooms during holidays until dad is up. I have three kids and I’m honestly relieved when they decide to play in their rooms so I can relax in the living room or tidy up the kitchen in peace, without toys or children running around. And I know how frustrating it is to constantly have to slow the kids down when dad worked a night shift...
Honestly, if your husband needs to sleep until noon, I would really aim for a house layout at this price point that adapts the sleeping, living, and play areas accordingly.

If the local authority cooperates, in my opinion, this is an option.

I have shifted only the basement slightly further to the east.

Where would you place the garage? I thought that, due to the slope of the site, it was the only logical option.

I would place the garage at the lower side of the property, facing the street, as suggested by @hanghaus2023.

I moved the basement a bit further east, but only the basement.

But this means the house has to be shifted significantly further back, and you lose garden space, right? I don't quite see the advantage of that.

I have quickly put together a new floor plan here (so please don’t pay too much attention to the windows and details. I also guessed the dimensions of the stairs, probably a bit too large?).
I decided to leave out the granny flat/apartment, which makes the basement much less complicated.
Overall, I find it more coherent. What do you think?
The only part I’m still unsure about is how to design the bathroom and utility room on the upper floor in a practical way. Feel free to share any suggestions.
Basement floor plan: garage for two cars, entrance area, stairs, living area with sofa.

Ground floor plan: living room, kitchen, dining area, bathroom, bedroom, stairwell.

Upper floor plan: bedroom, bathroom, hallway, stairwell.
