Understanding the 1970s Property Landscape

The 1970s was a transformative decade for the UK housing market. Post-war reconstruction had largely concluded, and the focus shifted towards modernisation and expansion. Properties from this era are often characterised by their unique architectural styles, construction methods, and materials. However, like any period, the 1970s brought its own set of challenges and potential defects. This guide aims to provide a thorough understanding of what to expect when buying a 1970s property, including typical defects, hazards, and how these homes differ from those built in the previous decade.

Architectural Characteristics of 1970s Properties

Design and Layout

The 1970s saw a departure from the more traditional designs of the 1950s and 1960s. Open-plan living became more popular, with larger windows to allow more natural light. The use of concrete and brick was prevalent, and many homes featured flat roofs or shallow-pitched roofs. The interiors often included fitted kitchens and built-in wardrobes, reflecting a shift towards convenience and modern living.

Materials and Construction

The construction methods of the 1970s were heavily influenced by the need for rapid housing development. Prefabricated elements became common, and there was a significant use of concrete, both in the structure and in external cladding. Timber frames were also used, although less frequently. The insulation standards of the time were not as stringent as today, which can lead to issues with energy efficiency.

Changes from the 1960s

Compared to the 1960s, 1970s properties often have a more modern aesthetic. The 1960s homes were typically more conservative in design, with smaller windows and more compartmentalised layouts. The 1970s embraced a more open and airy feel, with an emphasis on bringing the outdoors in. This was also the decade when central heating became more widespread, improving the overall comfort of homes.

Typical Defects in 1970s Properties

Structural Issues

Concrete Cancer

One of the most significant issues with 1970s properties is “concrete cancer” or spalling. This occurs when the steel reinforcement within concrete begins to rust, causing the concrete to crack and break away. This can be a serious structural issue and often requires professional assessment and repair.

Timber Decay

While not as common as in earlier decades, some 1970s properties do have timber elements that can suffer from rot or insect infestation. This is particularly true for properties with timber-framed windows or doors.

Roofing Problems

Flat Roofs

Many 1970s homes feature flat roofs, which are notorious for their tendency to leak. The materials used at the time, such as bitumen felt, have a limited lifespan and can deteriorate, leading to water ingress and potential damage to the interior of the property.

Insufficient Insulation

The insulation standards of the 1970s were not as high as today, meaning that many properties from this era suffer from poor thermal efficiency. This can result in higher heating costs and a less comfortable living environment.

Plumbing and Electrical Issues

Outdated Plumbing

The plumbing systems in 1970s properties can often be outdated, with galvanised steel pipes that are prone to corrosion and blockages. This can lead to reduced water pressure and potential leaks.

Electrical Safety

Electrical systems from the 1970s may not meet current safety standards. It is common to find old fuse boxes and wiring that may need to be upgraded to ensure safety and compliance with modern regulations.

Asbestos

Asbestos was widely used in construction during the 1970s, particularly in insulation, roofing, and textured coatings like Artex. While it is generally safe if undisturbed, any renovation work can pose serious health risks if asbestos fibres are released into the air.

Hazards and Risks

Health Hazards

Asbestos Exposure

As mentioned, asbestos is a significant concern in 1970s properties. If you plan to undertake any renovation work, it is crucial to have a professional asbestos survey conducted to identify and safely remove any asbestos-containing materials.

Lead Paint

Lead-based paint was still in use during the 1970s, particularly on woodwork and metal surfaces. Lead exposure can be harmful, especially to children, so it is important to test for and safely remove any lead paint.

Environmental Risks

Energy Efficiency

The energy efficiency of 1970s properties is generally lower than modern homes. Poor insulation, single-glazed windows, and outdated heating systems can result in higher energy bills and a larger carbon footprint. Upgrading these elements can be costly but is often necessary to improve the property’s efficiency and comfort.

Damp and Mould

Poor insulation and ventilation
