The Spooner timber framed house, was generally built with using a traditional style, full brick exterior but occasionally due to material shortages, they were also built using bricks at the lower level and profiled steel cladding sheets to the upper storey. This latter alteration caused many to confuse the Spooner Timber Framed House, with the very similar looking BISF (British Iron & Steel Federation) steel framed house.
Spooner houses were built as bungalows and 2-storey semi-detached and terraced houses.
Having a steep, medium or shallow pitch gable roof covered with tiles, profiled steel or asbestos cement sheets.
The external walls of houses were constructed of brick throughout, or in some cases up to first floor level with vertically profiled steel sheets above.
Some houses have a flat canopy over front door and some houses have steel framed windows.
The external front and rear walls of bungalows were usually finished in render.
