Morning guys, currently re-doing the Livingroom and the misses wants to replace the old gas fire with a new surround and fire, whereas I want to install an open coal\log fire. Currently the gas fire has been removed and a chimney sweeper coming today. The fire space is completely clear and ass it stands just a big brick chamber. What steps are need to be taken if I want to convert to an open fire? I would like to keep the brick chamber as large as possible and have a metal basket sitting in the chamber to hold the coal\logs. Could I render the brick chamber and paint? or does some sort of internal chamber surround need to be fitted?
