Dear forum members,
I am planning to build a single-family house and would like to have a masonry fireplace installed.
The fireplace will be placed between the living and dining areas. The chimney location is already fixed. The fireplace will be positioned next to the chimney and, depending on whether it is single-sided or double-sided, it will extend further into the room (see pictures).
I am generally okay with a single-sided fireplace, but I am unsure if I would have a good angled view of the glass from the sofa. That’s why I am considering an L-shaped fireplace, which allows a good angled view. This would almost act like a room divider, as it will probably extend about 80cm (31 inches) into the room.
What do you think about these ideas, or what would look better in your opinion?
Thanks!

There are also three-sided fireplaces, would that be an option? As far as I know, we need an airtight fireplace certified according to DIBt. Currently, there are no three-sided fireplaces available for this requirement.
Also, the same question would arise: does it protrude too far into the room?

I don’t quite understand.. so you would be completely against having a fireplace? What disadvantages would there be?The usual points that are always discussed in these threads:
- CO2 emissions
- Overheating of the room in new builds due to current insulation standards
- Possibly needing to open windows to provide the fireplace with enough air to start a fire
- Cost versus benefit (with controlled ventilation systems, a pressure sensor costing around 1000€ might be necessary if it’s not a room-air-independent fireplace)
…etc.

Concise answer: As little glass as possible, as much thermal mass as possible, build the stove as a masonry heater. Avoid fast-heating stoves like a Swedish stove.What’s the point of having little glass if you then can't see the fire at all?A

...etc.edit:
You don’t necessarily need a room air independent insert. In that case, you get the pressure monitor instead.

What’s the point of a small glass area if you can’t see the fire?The idea is to retain the heat longer by having more thermal mass. Larger glass areas mean less capacity to store heat.
