SYSTEM-BUILT HOUSING

Schindler houses, also known as AW Hawksley SGS properties, are a form of post-war system-built housing constructed between 1949 and 1954. Typically arranged as two-storey semi-detached or terraced homes, they combine a reinforced concrete structural frame with brick external walls, giving them a more conventional appearance than many non-traditional properties of the same era. The key risk with this construction lies in the concealed elements rather than the visible fabric. In particular, limited concrete cover to reinforcement and the long-term durability of galvanised wall ties are known concerns. As a result, condition can vary significantly between properties, and a detailed inspection is essential to understand structural performance and any requirement for remedial work.

A brief overview of the Rumble House, a rare non-traditional property type built in the early 1950s. This article explains its reinforced concrete construction, typical defects, and key inspection priorities, with a practical focus on roof panels, cracking, and long-term durability.

Quikform houses are a post-war, system-built form of UK housing developed from 1945 using reinforced concrete and clinker block construction. Typically arranged as two-storey semi-detached or terraced properties, they were designed for rapid delivery during acute housing shortages. While robust in concept, their long-term performance depends heavily on the condition of the concrete, embedded reinforcement, and moisture protection, making careful inspection essential prior to purchase.

Permacrete houses, also known as Cemacrete or Cemalite, are 1940s reinforced concrete system-built properties developed to address post-war housing shortages. Constructed using pre-cast slabs and reinforced concrete infill, they are typically two-storey semi-detached homes with rendered elevations and hipped tiled roofs. While robust in concept, long-term performance depends on the condition of embedded steel reinforcement, damp-proof detailing, and overall maintenance.

The Parkwall house is a 1960s system-built property manufactured by Sir Lindsay Parkinson & Co., with around 3,100 units constructed during the post-war housing drive. Typically found as bungalows or two-storey terraces, these homes feature plywood-clad front and rear elevations, brick flank walls, and either pitched tiled roofs or flat felted coverings. While innovative for their time, long-term performance depends heavily on the condition of the cladding, roof coverings, and any reinforced concrete structural elements, making careful inspection essential before purchase.

The O’Sullivan house is a rare post-war system-built property constructed in the late 1940s and early 1950s. Built with 11-inch concrete cavity walls, mild steel ties and reinforced concrete elements, these two-storey semi-detached homes are most commonly found in the Midlands and North of England. While robust in concept, they require careful assessment of vertical cracking, damp performance and any asbestos-containing components, particularly around openings and structural junctions.

Mowlem houses are system-built properties constructed between 1965 and 1981 using aerated lightweight concrete panels with reinforcement at key structural levels. Often referred to as “No-Fines” houses, they were built in significant numbers across the UK in bungalow, semi-detached and terraced forms. While widely accepted, common inspection priorities include cracking at separating wall junctions, long-term moisture control, and the management of asbestos-containing components such as soffit boards.

The MOW Demonstration No-Fines house is a rare 1940s Ministry of Works property constructed using reinforced no-fines concrete. With only two ever built, it represents an unusual form of post-war non-traditional housing. Its porous concrete walls rely on embedded steel reinforcement, making moisture control, cracking, and long-term concrete condition key considerations when assessing structural performance and ongoing maintenance requirements.

The MOW Demonstration Foamed Slag house is an exceptionally rare post-war experimental property, designed by the Ministry of Works in the 1940s using foamed slag aggregate concrete. With only two known examples constructed, this non-traditional two-storey semi-detached house features rendered reinforced concrete walls and a steep tiled roof. While historically significant, careful assessment of concrete durability, embedded reinforcement, and moisture performance is essential when considering purchase.

The MOW Demonstration Expanded Clay House is an exceptionally rare post-war Ministry of Works design, constructed using reinforced expanded clay aggregate concrete. With only two ever built, this non-traditional semi-detached house features rendered 8-inch concrete walls, continuous bar reinforcement above openings, and a tiled steep-pitch roof. Careful inspection of render condition, moisture exposure, and concealed reinforcement is essential when assessing structural durability and long-term performance.

Miller Temporary Bungalows are rare post-war, no-fines concrete prefabricated homes built between 1945 and 1946. Originally intended as temporary housing, surviving examples feature asbestos cement roofing, rendered concrete walls, and timber internal elements — all of which require careful inspection and ongoing maintenance consideration before purchase.

Miller No-Fines houses are a distinctive form of 1950s non-traditional concrete construction developed to address post-war housing shortages. Built using in-situ no-fines concrete and finished in render, they are durable in principle but rely heavily on effective moisture protection. Careful inspection of render condition, signs of damp penetration, and any evidence of reinforcement corrosion is essential when assessing long-term performance and mortgage suitability.

The Maxim House is a post-war reinforced concrete system-built property constructed between 1949 and 1954 by A A Stuart & Sons (Glasgow) Ltd. Built primarily in semi-detached and terraced forms, these homes feature dense reinforced concrete cavity walls with Pyroc render and concrete tiled pitched roofs. While structurally robust in design, their long-term performance depends on the condition of embedded steel reinforcement, with corrosion, carbonation, and concrete spalling representing the principal inspection considerations.

When considering a property purchase in the UK, understanding the history, construction, and potential risks associated with the property type is crucial. One such property type that demands attention is the Lowestoft Borough house. This article…

The Lamella House is a distinctive post-war non-traditional property built between 1946 and 1948 by F Hills & Sons Ltd. Constructed using rendered no-fines concrete at lower level with cavity brickwork above and a timber lamella grid roof structure, only 183 units were produced. Key inspection priorities include the condition of the concrete, potential steel corrosion, carbonation risk, and the long-term performance of the timber roof framework.
