I have used a couple of different suppliers to provide a quicker route to adding structures to my layout. Lasercut railway models, Lcut creative and Intentio. Of the 3 Intentio are by far the best engineered and are easier to assemble. Walls are double skin Areas such as windows and doors are less fragile. Some pictures of what l have achieved. The large building is a combination of two suitably altered to form more of what l needed.
