Historical Context and Manufacturing

The Reema Contrad house, a notable example of system-built properties, emerged during the late 1960s and continued into the 1970s. These homes were primarily manufactured by Reema Ltd, a company renowned for its innovative approach to prefabricated housing. The Reema Contrad house, also known as an “Engineered Home,” was part of a broader movement to address the post-war housing shortage in the UK. This period saw a surge in the construction of prefabricated homes, which were quicker and more cost-effective to build compared to traditional brick-and-mortar houses.

The Reema Contrad houses were predominantly constructed in suburban areas, providing affordable housing solutions for the growing population. These properties were typically two-storey semi-detached houses, designed to offer a balance between functionality and aesthetic appeal. The construction methods and materials used in these homes were reflective of the technological advancements of the time, aiming to provide durable and efficient living spaces.

Design and Construction Characteristics

External Walls and Cladding

The external walls of Reema Contrad houses are a distinctive feature, often comprising storey-height timber frame panels. These panels are clad with horizontal timber boarding up to the first-floor level, with tile hanging on timber battens above. This combination of materials not only provided a visually appealing facade but also contributed to the structural integrity of the building. The gable walls were typically clad with brick or stone, which was returned around the corners to enhance the overall stability and aesthetic of the property.

Roof Structure

The roof of a Reema Contrad house is characterized by a medium pitch gable design, covered with concrete tiles. Timber trusses supported by a pre-cast (PC) lintel form the primary structure of the roof. This design choice was aimed at providing a robust and weather-resistant covering, capable of withstanding the varied climatic conditions of the UK.

Floors and Ceilings

The ground floor of these homes is constructed from concrete, providing a solid and durable base. The first floor, on the other hand, consists of timber joists supported by galvanized joist hangers. This combination of materials ensures a balance between strength and flexibility, accommodating the dynamic loads experienced in a residential setting. The ceilings are typically lined with plasterboard, offering a smooth and clean finish.

Internal Partitions

Internally, the Reema Contrad houses feature load-bearing timber stud partitions lined with plasterboard. Non-loadbearing partitions are often of the Paramount type, which are lightweight and easy to install. These internal walls provide the necessary separation between rooms while maintaining the overall structural integrity of the building.

Typical Hazards and Risks

Structural Concerns

One of the primary concerns with Reema Contrad houses is the potential for structural degradation over time. The use of reinforced concrete and timber in the construction means that these materials are susceptible to issues such as corrosion and rot. The BRE Digest 444 provides guidance on the inspection and assessment of reinforced concrete durability, highlighting the importance of regular maintenance and repair to prevent significant structural issues.

Thermal Insulation and Energy Efficiency

The original design of Reema Contrad houses did not prioritize thermal insulation to the extent that modern building standards do. As a result, these homes may suffer from poor energy efficiency, leading to higher heating costs and reduced comfort levels. Retrofitting insulation between the studs of timber frame panels can significantly improve the thermal performance of these properties.

Damp and Moisture Ingress

Damp and moisture ingress are common issues in older properties, and Reema Contrad houses are no exception. The concrete edge beam and DPC (damp proof course) are critical components in preventing moisture from penetrating the structure. However, over time, these elements can deteriorate, leading to damp problems that can affect both the structural integrity and the living conditions within the home.

Defective Premises Act and Reema Contrad Houses

The Defective Premises Act 1972 imposes a duty on builders, developers, and landlords to ensure that properties are constructed and maintained to a reasonable standard. While the Reema Contrad houses were built to the standards of their time, they may not meet modern building regulations. As such, these properties could be considered defective under the Act if they exhibit significant structural or safety issues.

Homebuyers and investors should be aware of the potential liabilities associated with purchasing a Reema Contrad house. A thorough building survey conducted by a qualified surveyor is essential to identify any defects and assess the overall condition of the property. This will help to ensure that any necessary repairs or upgrades are accounted for before completing the purchase.

Inspection and Assessment Guide

External Inspection

When inspecting a Reema Contrad house, start with a thorough examination of the external walls and cladding. Look for signs of deterioration in the timber boarding and tile hanging, such as rot, warping, or loose tiles. Check the condition of the brick or stone cladding on the gable walls, paying particular attention to any cracks or signs of movement.

Roof Inspection

Inspect the roof for any missing or damaged concrete tiles, as well as any signs of sagging or unevenness in the roofline. Check the condition of the timber trusses and PC lintel, looking for any signs of rot, corrosion, or structural damage. Ensure that the roof is adequately ventilated to prevent moisture buildup and condensation.

Internal Inspection

Inside the property, examine the condition of the plasterboard linings on the walls and ceilings. Look for any signs of damp, mould, or staining, which could indicate moisture ingress. Check the condition of the timber stud partitions and Paramount partitions, ensuring that they are structurally sound and free from damage.

Floor Inspection

Inspect the ground floor for any signs of cracking or movement in the concrete. Check the condition of the timber joists on the first floor, looking for any signs of rot, warping, or damage to the galvanized joist hangers. Ensure that the floors are level and free from any significant deflections or unevenness.

Damp Proof Course and Moisture Control

Examine the condition of the DPC and concrete edge beam, looking for any signs of deterioration or failure. Check for any signs of rising damp or moisture ingress at the base of the walls, which could indicate issues with the DPC. Ensure that the property has adequate drainage and ventilation to prevent moisture buildup.

Common Defects in Reema Contrad Houses

Corrosion of Reinforced Concrete

One of the most common defects in Reema Contrad houses is the corrosion of reinforced concrete elements. This can lead to spalling, cracking, and a reduction in the overall structural integrity of the property. Regular inspections and maintenance are essential to identify and address any signs of corrosion before they become significant issues.

Timber Rot and Decay

Timber elements in Reema Contrad houses, such as the timber frame panels and roof trusses, are susceptible to rot and decay, particularly if they have been exposed to moisture. Regular inspections and maintenance are essential to identify and address any signs of timber rot, ensuring that the structural integrity of the property is maintained.
