As I mentioned in an earlier post I won an auction for some painted MDF ruins. As they're painted all I had to do was glue them together. This was a two stage process. The outer and inner walls were PVA'd together first and then the separate pieces were assembled into the corner sections. This was all straightforward, the only fiddly bit was fixing the triangular piece used to strengthen the corner.
Anyway here's a couple of photos of the finished article, not bad for a fiver.
