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

I like the floor plan. Are you planning to have only one sink upstairs? If the bathroom is for four people, I would definitely go for two.

A second sink is planned... the views? Oh Lord... still a huge construction site...

That just won’t work with the roof either.


No, yours/the one you suggest doesn’t work with the roof.

It would run straight across the upstairs hallway and drastically reduce the hallway’s clear width both upstairs and downstairs (if that’s even possible).


Not at all. The chimney is located between the children’s rooms upstairs… somewhere around there.

I think the stove in the hallway is “out of place.”

The chimney, not the stove…
Notstrom schrieb:

You want to have that thing on display after all.


Exactly. Do you understand what I’m saying or do you think I’m a bit slow?
Notstrom schrieb:

The niche doesn’t have a door, only the storage room does.


Two doors lead off from the niche! The niche is probably going to be very cramped with four people around, which will then cause problems when trying to go to the bathroom.

Currently, as mentioned, along the house facade -> As I understand your suggestion, the stove would be in the hallway and therefore also on the upper floor hallway. But I'll keep that in mind, maybe we can simulate it tomorrow.

I don’t consider you limited, nor did I intend to imply that.

The niche has a door and one in the guest bathroom; in this view, that would indeed be two, that’s correct.

What does Tö actually mean?

"Tö" means WC, that is, toilet, commode, bowl, etc.

This is your currently planned chimney at its full height ...

Yes, the exterior chimney is often left out by those presenting the elevations because it turns the design from messy into a disaster. This is the second time the planner has positioned it outside. It’s really bad practice! A chimney should be placed as centrally as possible to avoid having a pipe sticking out at the roof edge—especially with a hip roof.

Personally, I would leave it out. If you’re already uncertain now, in two years it will be completely unnecessary. No one wants to clean it, chop wood, or even buy it. The energy-saving regulations-compliant house is too warm to need additional heating—the incentive is gone. Save yourselves the 5,000 to 10,000 (currency) and spend it on nice cabinets or something similar instead.
