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

For the left parking space in the garage, you really have to turn the steering wheel a lot, don’t you?

The concrete at the entrance can be sealed, for example with Storm Dry, if it hasn’t been done yet. Otherwise, it will turn green faster than you’d like.

Nice house 🙂

Do you have direct access from the garage to the house? Because of the steps leading up to the house, is there about a 60-70 cm (24-28 inches) difference between the floor level inside the house and the garage?

Yes, we do have access from the garage to the house 🙂

The level difference from the street to the house is indeed about 70 cm (28 inches).

It’s quite a tight turn to get into the left parking space in the garage, isn’t it?

You can waterproof the concrete at the entrance, for example with Storm Dry, if that hasn’t been done yet. Otherwise, it tends to turn green faster than you’d like.

Yes, the entrance is indeed a bit tricky, but it’s required by the development plan.

How does the waterproofing work? Which product should I use? They have so many options :-)

Storm Dry facade protection cream. It is available at the major river, but I personally bought a tub on eBay (via price offer) for a significantly better price.

That must be a fire door with a 30-minute rating, right?

Wow... how much of it do you need? And who applies it? Painters?
