Historical Context and Manufacturing The Kingstone house, also known as the Tarran house, is a unique property type that emerged in the post-World War II era. Manufactured by Tarran Industries Ltd, these homes were designed to…

The Keyhouse Unibuilt house is a rare post-war, system-built property dating from 1946, with only four examples ever constructed. Designed by Richard Sheppard and G Grey Wornum, it uses an early steel frame with precast concrete floors and asbestos cement wall panels. From a surveying perspective, the primary risks relate to steel corrosion, deterioration of precast concrete elements, and the management of asbestos-containing materials, all of which require careful inspection and clear professional reporting.

The Kelvin House is an exceptionally rare inter-war, steel-framed bungalow type dating from 1926, identifiable by its shallow hipped copper roof and roughcast rendered walls. Its mixed steel and timber construction demands informed inspection, with long-term performance closely linked to corrosion control, moisture management, and ongoing maintenance rather than surface appearance alone.

A concise overview of the Integer House, a rare 1960s non-traditional bungalow built using steel-framed, aluminium-clad panel construction. The article explains its history, construction details, common defects, and the key inspection priorities to understand before purchase.

IBIS houses are a form of 1960s system-built, non-traditional housing constructed using a steel frame and prefabricated wall panels. While robust for their time, these properties require careful inspection today, particularly for steel corrosion, moisture ingress, insulation performance, and fire safety, where original materials remain in place.

Howard Type B houses are post-war, non-traditional homes built between 1945 and 1950 using a steel frame with asbestos cement cladding. Understanding asbestos risks, steel corrosion, and panel joint performance is central to assessing condition and long-term suitability.

The Howard Type A house is an exceptionally rare post-war, steel-framed property constructed in 1945, with only two examples ever built. Characterised by asbestos cement roof and wall panels, timber-framed cavity construction, and a complex steel structural frame, these houses require particularly careful inspection. Long-term performance is closely linked to corrosion protection, moisture control, and the condition and management of asbestos-containing materials.

The Homeville Industrialised House is a post-war system-built property developed between 1963 and 1970 using steel framing and prefabricated wall components. Found in a range of forms including bungalows and two-storey houses, these properties are generally robust but require careful inspection of steel stanchions, gable wall panels, and roof space construction. Understanding the construction type and its common defects is essential before purchase.

The Hitchins House is a rare post-war, steel-framed system-built property constructed in 1946, with only 50 units produced. Designed by A G Macdonald and manufactured by Hitchins Steel Core Buildings Ltd, these two-storey semi-detached houses combine a steel structural frame with precast concrete wall panels. While historically significant, their long-term performance depends heavily on the condition of the steelwork, protective coatings, asbestos-containing roofing materials, and moisture control measures, making careful inspection essential.

Hills Presweld houses are a post-war, non-traditional property type built in limited numbers during the 1940s. Their steel-framed construction and varied external wall systems mean condition is far more important than appearance. Corrosion to steel stanchions and cracking to no-fines concrete or precast wall panels are common inspection priorities and can have a direct bearing on mortgageability and long-term maintenance.

A **Hillcon house** is a rare post-war, system-built semi-detached property dating from 1952. Constructed using a steel lattice frame with rendered external walls and concrete detailing, these houses are most commonly associated with corrosion risk to the steel stanchions and age-related moisture issues. Careful inspection of the frame, render condition, and damp-proofing is essential when assessing their condition and long-term performance.

The Hawthorn Leslie house, also known as HLB or Plasteel, is a 1960s system-built property type developed to meet post-war housing demand. Constructed using a steel frame with prefabricated cladding panels, these houses are most commonly found on suburban estates and appear as bungalows or two-storey detached, semi-detached, and terraced homes. While robust in concept, their long-term performance depends heavily on the condition of the steel frame, external cladding, and weatherproofing details, making careful inspection essential when assessing their suitability for purchase.

The Grid House is a mid-1960s system-built property designed and manufactured by Morrison and Partners. Constructed using a steel frame with timber infill panels and flat roof construction, around 160 examples were built across the UK. While innovative for their time, Grid Houses present specific inspection considerations today, particularly around moisture control, timber condition, asbestos-containing cladding, and the long-term performance of flat roofs.

Historical Context and Background The Grenfell Baines house, a unique architectural marvel, stands as a testament to post-war ingenuity and the drive for rapid housing solutions. Designed by the Grenfell Baines Group and manufactured by English…

Gee Walker & Slater houses are an exceptionally rare form of post-war non-traditional construction, with only two ever built in 1946. Formed using a steel frame with aerated concrete panel infill and asbestos cement roofing, these semi-detached houses reflect the experimental building methods adopted immediately after the Second World War. Their unusual construction places particular emphasis on condition, corrosion control, and asbestos management, making a detailed building survey essential.
