After painstakingly working out the measurements and calculations based on the stove size and fire regulations, my (very) rough drawing of a fireplace has miraculously been turned into reality.
The colours and textures of the materials fit perfectly with the planned look and feel for the house, and they've all been up-cycled from the old house so we have a lovely juxtaposition of old with new. Bricks from the old conservatory have been used to construct the lower half of the fireplace, with the lintel made from a sawn-down beam that used to be in the kitchen.
We may have to wait a little while to get the fire to go inside, but for the moment it looks great just the way it is!
