One further question: Now the fireplace destruction has been filled up and replastered I want to do a "hole-in-the-wall" type fire but am having trouble sourcing a box frame type trim. The fire will not be used except for candles so doesn't need to be very robust. I think it would make a nice feature rather than closing it up with some ugly air vent in it. Local fireplace dealers only supply the metal trim with 3 sides for your traditional fires and don't stock the hole in the wall type with 4 sides. One design place can make a bespoke one in stainless steel for £300. choke. There is no way we could make one, don't have the skills, tools or time. Any suggestions as to where we might be able to source such a thing, preferable with mail order as travel to Great Britain is out of the question at the moment.
thanks as always Suzanne
