from the inside
Am expecting a gap around the new fourth wall – sliver of light at both right and left – as they’ll get a very thin wood strip (or possibly card) to finish the edges.
So I gave my apologies and made my excuses to the woman and child at the other end of the long gallery and stuck my arm, with camera, down past them to get a shot or two.

Before the edges can be finished however, the outer face needs woodwork, brickwork and all sorts of fun and games.
