Homeowner Requirements
Style, roof type, building type: Bauhaus style, flat roof
Basement, floors: Basement yes, ground floor, upper floor
Number of residents, ages: 3 people, potentially 4: 33, 30, 2 years old
Space requirements on ground and upper floors: Initially planned 180 m² (about 1,940 sq ft) on two stories, now reduced to 160 m² (about 1,720 sq ft) after feedback, with the ground floor slightly larger than the upper floor, around 75–85 m² (810–915 sq ft)
Office: Family use or home office? Yes, in the basement (guest room <-> office)
Overnight guests per year: Hard to say, probably about 10 times per year with 2–5 guests each time
Open or closed architecture: Rather open
Conservative or modern construction: Rather modern
Open kitchen, cooking island: Island
Number of dining spaces: 1
Fireplace: Yes
Music/sound system wall: Our soundbar is sufficient
Balcony, roof terrace: Maybe, undecided (Architect’s comment: How often do you really go out for a beer on the balcony/roof terrace instead of the nice terrace on the ground floor?)
Garage, carport: Double garage, possibly single garage with carport
Kitchen garden, greenhouse: Small but nice (a few tomatoes, cucumbers, zucchinis…)

House Design
Planning by: Architect

What do you particularly like? Why? We like the architecture with the two offset rectangles, though we wonder if the extra cost (no price estimate yet) justifies this. We believe it is structurally more challenging than a simple "cube."
What don’t you like? Why? The size of the bedroom/walk-in closet/children’s room. It feels like the bedroom is missing 2–5 m² (about 20–55 sq ft), as is the second children’s room.
Price estimate according to architect/planner: The initial draft was around 550,000 EUR
Personal price limit for the house, including fixtures: 620,000 EUR
Preferred heating technology: Indifferent, but tendency toward heat pump.

If you had to give up something, which details/finishes
- You can give up: the current shape (nice but a cube would also do)
- You cannot give up: space

Why is the design the way it is now? For example:
Standard design from the planner? This is the second design resulting from last week’s discussion with us, and we find it very successful.
Which wishes were implemented by the architect? Absolutely, plus the idea he had to move the kitchen during development. The guest room has now moved to the basement, allowing more space on the ground floor (beforehand, it felt quite cramped and “squeezed”).
What makes it especially good or bad in your opinion? The architecture

...and now I’ll leave you alone with our house

It’s me again... progress is being made, and I will share the latest versions of the plans and views in the next few days.

There is only one issue I’m not satisfied with yet: the basement. How would you suggest optimizing the home office / guest room / toilet / shower from your perspective?

Could you please upload the latest ground floor plan again? Because that’s where your mentioned shower toilet is supposed to be, at least I don’t see it in the basement.
Also, it’s important right now since you need the load-bearing elements. I’d say: once the ground floor is optimized, the basement has to be adjusted accordingly.

The shower toilet in the basement is planned right next to the home office.
We have placed the toilet and shower freely in the space for now; a more detailed plan hasn’t been developed yet.
I would like to have the home office there because I want to benefit from the natural light coming from the light well.
Current challenges:
- The “living basement area” should include a sofa bed
- Since the home office will also be my hobby room, I would like to set up a TV
- Plus a sofa bed
- We find the toilet/shower area too large for the entire “Basement 1” space, or put differently: we don’t want to dedicate the whole room to the toilet/shower
- We considered an access door from the home office
- We find the room layout somewhat awkward, especially because of the spatial complexity
- The load-bearing walls are the walls of the basement corridor

I would swap the laundry room with the bathroom in the basement.

You don’t necessarily need the natural light from the light well in the laundry room.

By the way, the loops of the underfloor heating in the laundry room don’t need to be laid as closely together. My wife always complains that it’s too warm in the laundry room...

How is the light well for the laundry room and the ground floor entrance area supposed to work?

The light well is offset.
