How to Lay Out a Fireplace

The dimensions that decide whether the room works, whatever it ends up looking like. The thing every seat in the room is already pointed at.

  1. 1

    What the room is arranged around

    A fireplace remodel is surround, hearth and mantel — and, increasingly, undoing a television mounted above it. The firebox usually stays; what changes is the material facing it, its proportions, and whether the chimney breast keeps its alcoves or loses them.

  2. 2

    Rule 1

    Leave 16in of clear hearth in front and 8in to each side of the opening.

  3. 3

    Rule 2

    A mantel sits at 54in for a standard opening; higher and the room stretches, lower and it crowds the fire.

  4. 4

    Rule 3

    Keep alcove joinery to 18in deep — beyond that it projects past the chimney breast and reads as lumpy.

  5. 5

    Rule 4

    A television centre wants to be around 42in from the floor, which is why it and a fire rarely share a wall well.

  6. 6

    Rule 5

    Seating faces the fire at 8ft or less, the same conversation distance the rest of the room uses.

  7. 7

    When it is tight

    In a small room, taking the surround material to the ceiling makes the wall taller rather than busier — a mantel with a gap of blank wall above it does the opposite and cuts the height in half.

Questions

What should I decide first in a fireplace remodel?
A fireplace remodel is surround, hearth and mantel — and, increasingly, undoing a television mounted above it. The firebox usually stays; what changes is the material facing it, its proportions, and whether the chimney breast keeps its alcoves or loses them.
What goes wrong most often?
A television mounted above the fire, too high to watch and too hot to be there. A surround material chosen from a sample rather than seen at full height.
Will it work in a small fireplace?
In a small room, taking the surround material to the ceiling makes the wall taller rather than busier — a mantel with a gap of blank wall above it does the opposite and cuts the height in half.
Can I see it on my own fireplace before starting?
Yes — photograph the space and run it through the Studio. It is generated imagery, so compare the render against your photo rather than treating it as a plan.
