Hello everyone,

Our floor plan has actually been finalized for quite some time. During the structural calculations, it was noticed that the position of the chimney is unfavorable for the roof structure. It runs directly through the ridge rafters.
I had agreed with the architectural firm to move the chimney half a meter (about 20 inches). However, this morning it was realized that this is not enough and it needs to be shifted another 8 cm (3 inches), because the roofer also needs space for the metal flashing at the ridge (I’m not exactly sure what that means).
As a result, the chimney on the upper floor is now located in the wall between the two children’s bedrooms.
Apart from the fact that the chimney on the ground floor is gradually shifting further to the right, affecting the appearance, are there any disadvantages that might arise from this? For example, noise issues or something similar?
(The wall is planned as an 11.5 cm (4.5 inch) sand-lime brick wall.)

More likely 12.5 cm (5 inches)

I’ll be honest: some days I simply don’t feel like searching through a poster’s entire post history to find whether and where the house (or at least the floor plans) are shown as a whole. The zoomed-in crop of images focusing on specific details unfortunately doesn’t provide enough context, which makes giving advice more difficult.

We basically have two fireplaces – a gas one and a wood-burning stove – located on either side of the wall. The only downside I noticed is a small expansion joint in the wall that needs to be sealed with silicone (???), which remains somewhat visible; the plasterer also has to be extra careful and may need to use mesh tape if necessary.

Oh, and if in doubt, the heat will slightly radiate into two rooms on your side (assuming it’s for a wood stove).

In some cases, the fireplaces here have been built around with masonry – talk to your designer about which parts of the prefabricated fireplace unit remain and where walls can or must be built.

Oh, I hadn’t thought that the entire floor plan was needed.
Of course, you don’t have to gather it all together yourself:

Floor plan of a house with garage, workshop, utility room, entrance hall, living/dining/kitchen area, kitchen, guest room and WC

Attic floor plan with bedroom, two children’s rooms, bathroom and corridor.


But why 12.5?

OK, a slight heat emission isn’t really a problem.
We are building with a general contractor (GC). They are providing the prefabricated chimney as well as the walls and plastering. So hopefully they can coordinate all of that.

I can just imagine that the plaster in the other child’s room might be more prone to cracking at the point where the chimney meets the calcium silicate brick wall. (What kind of brick is that exactly?)

I seem to recall that from the start, I said the chimney should be placed in the corner.
We also integrated our chimney on the upper floor as part of the wall. The room wall was aligned flush with the chimney and then covered together. I can't see what disadvantages that would have. Noise in the kids’ room? Are they already snoring that loudly at night?

Which fireplace have you chosen for the living room? With a full-height design, chimneys can be easily concealed, whether they are on the left, right, or centered on the wall.

Twelve and a half instead of eight, because I would always work in whole octameter steps. Does your drawing show the shift as +50 or already +50 +8?

It’s a pity that the other drawings don’t allow me to come up with a more refined or elegant solution in this case.

I have to admit, when I saw and commented on your plans back then, I probably overlooked the chimney on the ridge. At least in the elevation view, that should have been noticeable.

If it’s only about 8cm (3 inches) up there (well, with tolerance maybe better 10cm (4 inches)), then perhaps the ridge line could be shifted by slightly adjusting the roof overhangs?

That would seem more elegant to me than having to let the chimney protrude into the kids’ room as well.

The "material transition" between the interior wall and chimney is unproblematic; an expansion joint can be color-matched.
