I'm in the midst of renovation a small terraced house, and want to
reinstate the front doorway as it was originally built, with a
surround like the one in the link below, to matches all the others in
The surrounds were carved stone, and ideally I'd get one from the
local reclamation yard (but none are in stock and they get them in
only rarely). I could get a new one carved at a cost of thousands (no
thanks) so am wondering if there is some way I could make a cast
cement version. I would I go about this? Could I somehow take a
cast off an existing doorway (I do have access to one), then use that
to make a mould? Then attach the casting to the side of the house
somehow? It's really the part above the door I'm talking about; I
think the sides could be done using sand/cement render.
Would some form of polymer be a better bet?
The bulk of the surround is about 0.75" thick, except for the
plinth/shelf bit which is probably about 3" deep.
I'm not subject to conservation area rules or anything like that, so
there's no problem not using the original materials.
Any thoughts please? Or is this idea a non starter?
