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.

The Kirton house is a rare 1920s reinforced concrete terraced property constructed during the post-war housing boom. With only eight built, it represents an uncommon non-traditional construction type featuring rendered concrete walls, cast-in ventilation cavities, and a hipped concrete tiled roof. Its reinforced concrete frame and moisture management detailing require careful inspection, particularly in relation to carbonation risk, potential reinforcement corrosion, and long-term durability.

Incast houses are rare 1940s no-fines reinforced concrete homes built by the Metropolitan Concrete Co. Ltd to address post-war housing shortages. Typically two-storey and rendered throughout, they feature reinforced concrete walls, concrete strip foundations, and a distinctive flat-roofed bay window. Their long-term performance depends on the condition of the concrete, embedded reinforcement, and protection against moisture ingress, making careful inspection essential before purchase.

The Herald house, also known as the Page-Johnson house, is a 1960s non-traditional property combining timber-framed front and rear elevations with lightweight and dense concrete flank and separating walls. Typically found on suburban estates, these homes feature shallow pitch hipped roofs and timber cladding, with key inspection concerns focusing on moisture protection, timber condition, and potential concrete deterioration.
