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

Well, first of all, a fireplace creates dirt. You get mess from the ash, from the wood where sometimes animals might nest, and of course, you always have to clean the glass door.
Then, it’s expensive. The initial purchase costs money, the wood has to be delivered, and the chimney sweep regularly needs to be paid. Also, it takes up space in the house, which could often be better used, and that costs money too.
Additionally, during storms (which we now have regularly), the chimney makes noise. I haven’t experienced one that doesn’t howl or hiss in strong winds.
As an environmentally conscious father, you probably don’t want to pollute the air with unnecessary CO2, right?! ops:
The biggest drawback, however, is that in energy-efficient homes built according to the energy saving regulations (which applies to all new constructions), the desire for a cozy fireplace simply doesn’t arise anymore. It’s already warm and comfortable inside. There are no drafts, no cold spots, no damp corners, or uninsulated roofs. On the contrary – lighting a fireplace would cause heat buildup that’s hard to bear.
Result: the fireplace stays unused 99.9% of the year.

Rarely have I read such nonsense.

Mine is on every day in winter.
For me, there’s neither much mess from ash nor do I have to clean the glass constantly, and I don’t experience heat buildup at all.
And it’s the first time I’ve heard of a chimney making noise.

These kinds of arguments always come from the “fireplace opponents.”

I wouldn’t want to do without mine.

When was the house built? I’ve always been a fan of fireplaces and really wanted one. However, a colleague who built his home in 2017 had similar experiences to kaho and suggested I should check it out first. I went over for a beer and now I’m glad I don’t have one.
The dirt and such is still manageable — I know it from my parents’ old house, but that was an older building.
But the heat in his newly built house was so unbearable that after about 10 minutes we basically had to open all the windows.

We had planned the fireplace ourselves. However, other things have become more important to us over time.

Moved in 2018. KfW55 house, barely missed the 40 target.
When I heat fully, with two firings, the temperature only rises slightly. But that might also be because our living/dining area is 52sqm (560 sq ft) and is open to the hallway and upper floor.
And by the way, I designed it myself.

And by the way, it was also self-designed.

I’m curious because I’m lighting the fireplace for the first time today. We have the same setup, so I’m not worried it will turn into a sauna like Katja describes :-p. @kaho674 I’ll report back here later!
