Walthamstow garage was originally a tram depot, later a trolleybus depot, and finally a bus garage. The fine 'Tramways Offices' building still stands surrounded by a modern housing estate.
This large kit builds the front of the main garage shed and the former tower wagon shed, along with the office building.
Despite the various buildings being half relief, the model requires an area approximately 27" x 18". This will provide an area that can be used as a bus parking yard, and also a small part of the road that passed outside. 
Because of the large size of the main building, it is advised that the model is permanently fixed to a base - 6mm MDF would be fine. The base can be sprayed with grey car aerosol to represent tarmac.
