Fireplace - Misplanning by architects / general contractor

It should also be considered here that a chimney should always go above the ridge because of skylights or, if you don't have any, because of the neighbors.

I didn't know that either.

That is also not generally correct. The chimney or the opening must maintain a certain distance – sometimes this results in that "asparagus" sticking out, but it does not necessarily mean that it has to be higher than the ridge.

I also find it exaggerated to consult an expert for every trade; in my opinion, that is not the task of an expert. I thought their job was to check the performance of the executing personnel.
As a customer, I am also entitled to expertise from those professionals themselves.

I think this just slipped through... planned a modern villa... with a chimney... and suddenly eyes are opened to the fact that the chimney is located here on the upper floor.
That comes from silly routine.

But I would have chosen a more central location and then a masonry chimney, although I like stainless steel. But these are better suited for retrofitting.

I have to be honest, a chimney does not belong on the exterior wall of a hip roof. Architects and home builders know that. Otherwise, you just end up with a strange spike on the roof. For me, that would be a deal breaker for the chimney. It’s not that important and if I were to build again, I wouldn’t install a chimney at all.

If you ask me, scratch the chimney from the plan and put an aquarium in that spot instead. Done!

Visually, I agree with you. But in terms of cost and energy efficiency, an exterior chimney is better...

P.S. we have a Schiedel air shaft chimney ourselves. The intake is through the air shaft.

Are there possibly exterior chimneys with a draft enhancer mounted on top? I have simply seen such caps with a "wheel" that is supposed to improve the draft?

I would talk to the chimney sweep to see if he has any ideas.

Well, it should be clear that the chimney requires a certain height to work properly. Otherwise, such a stove simply doesn’t function. In my opinion, this actually has nothing to do with the stove itself.

Who should that be clear to? The architect? Definitely yes, because as you wrote, it is independent of the stove and something general. Also, that the chimney must protrude at least 1 meter above the ridge or depend on the neighboring buildings to avoid odor nuisance. As far as I know, that is building law which the architect should be aware of. Whether the chimney then gets sufficient fresh air to ensure clean combustion, that is the stove builder’s responsibility, I wouldn’t see that with the architect.
But I see it differently that a building layman/customer must know such things (i.e., lengths of chimneys). I hire the expertise of a construction professional (aka architect) precisely because I am a layman. That

I do not see the necessity of necessarily involving an expert to design something like this correctly at all. Would it have helped? Sure, but to hire an expert for every little thing (see toilet) already in the design phase is absurd. The architect’s job is not that of an artist but still a technical one, and he is responsible for planning and adhering to technical rules.

Interestingly, in our case, a fresh bachelor initially made the plans, including the submission planning. There the chimney also ended below the ridge. Our architect then quickly pointed out to his protégé that he should draw it as he had learned... so it seems entirely reasonable to expect this from an architect if an architect himself sees it that way.

A counter question: does a building layman aka customer also have to know how much window area a room requires to be adequately lit or that fixed glazing on the upper floor requires fall protection according to TRAV, or where load-bearing walls are necessary? I mean no.

We deliberately chose the stainless steel exterior chimney instead of the masonry chimney because it takes up less space INSIDE the house. In the living room, it would have still been acceptable, but on the ground floor, the chimney would have taken up space in one of our already small children's rooms, and it would no longer have been possible to furnish it sensibly. Additionally, it would have been located near the piano on the upper floor, which is absolutely not good for the instrument. Therefore, it was not really a question of price but of space.

I have to be honest, a chimney does not belong on the exterior wall with a hip roof. Architects and home builders know that. Otherwise, you just end up with a weird stick on the roof. For me, that would be a deal-breaker for the chimney. It’s not that important and if I were to build again, I wouldn’t install a chimney at all.

If you ask me, just remove the chimney from the plan and instead put an aquarium in that spot. Done!

I don’t like those things on exterior walls either, especially not with a hip roof, but whether that’s really the proper way? I find that just as hard to say as “it’s not that important.” It can vary quite a bit individually, just like tastes in aquariums. For me, those rank just behind garden gnomes and cat scratching posts and also ruin any tasteful interior. It’s a matter of taste. If it were up to me, I would also skip the shiny metal (and oddball), although a chimney is important to us. But in this case, the exterior appearance of the house would be more important to me. However, it’s not about my taste but the client’s [emoji4]

Is there no way to move the chimney inward? If not, why not? Has construction already started?

And the fact that the chimney starts on the ground floor must be for structural reasons? Can't an internal chimney start on the upper floor? And what collides with a piano there? The heat?
