after a long time of thinking over, I've finally bought Terry Pratchetts Unseen University Cut-out Book. The book itself is a masterpiece, so I couldn't resist building a test built out of it. When I've realized the true size of the whole building complex, I've decided to scale it down to 50% of original size.
The base is added so that the model doesn't get lost so easily... It's not exactly perfect plus it needs to trim the edges with some wooden lath.
Anyway - behold, The Boathouse!
