Reema houses came in two forms:  Due to structural degradation and the use of asbestos in the wall and roof insulation, both are difficult to obtain a mortgage on today. The Reema Hollow Panel is listed universally as defective after a Government-sponsored investigation and the subsequent Housing Defects Act 1984, while the Reema Conclad is often mis-recognised as a Hollow Panel. Between September 1945 and March 1946, Sweden exported 5,000 prefabricated houses to the UK and 2,100 to France. The design was adapted by the MoW from a standard Swedish kit, with the all-timber houses arriving in flat sections, and then stored at the docks for allocation. In England and Wales this was often in small numbers to rural areas in support of farm workers. The first of these houses were built at Abbots Langley, Hertfordshire, in January 1946. There are two basic designs: semi-detached houses with a single storey utility extension and semi-detached dormer bungalows. A pair of the bungalows at Auckley near Doncaster (Grid Ref: SE651012) have been listed by Historic England (their ref: 1392257). In Scotland a slightly different style of house (without the single-storey utility extension) was erected in large estates in Edinburgh, Glasgow, Inverness and elsewhere. The Tarran was designed by building firm of Tarran Industries Ltd. of Hull. A wooden frame designed bungalow, over clad with precast concrete panels. 19,014 Tarrans were erected under the Temporary Housing act, but one- and two-storey variants were built in some numbers afterwards.

Produced by the London-based Selection Engineering Company Ltd, the three versions of the Uni-Seco were largely erected in London and the southeast. A two-bedroom flat-roofed bungalow, it had a resin-bonded plywood timber frame with asbestos wall sections, it was based on a military wartime office design. With dimensions of by , the first two versions included the MoW standard kitchen/bathroom service unit, plus a lounge; Mark 3s had a central entrance over the original side door.
