Historical Context and Origins

The Aluminium House, a unique and intriguing property type, emerged in the post-World War II era. Specifically, these homes were constructed in 1950, a period marked by a significant housing shortage in the UK. The Aluminium House was a product of innovative thinking and a response to the urgent need for quick, cost-effective housing solutions. The primary manufacturers of these homes were A W Hawksley Ltd, with the design credited to the Bristol Aeroplane Company. This collaboration between a manufacturing firm and an aeroplane company resulted in a distinctive property type that stands out in the annals of British housing history.

Typical Locations and Distribution

Only two Aluminium Houses were built, making them exceedingly rare. These properties are typically found in areas where there was a pressing need for rapid housing development post-war. While specific locations are not widely documented, it is likely that these homes were situated in regions heavily affected by wartime destruction or areas experiencing significant population growth.

Characteristics and Design Features

External Appearance

Aluminium Houses are easily identifiable by their unique external features. They are two-storey semi-detached houses with a shallow pitch gable roof covered with profiled metal sheeting. The external walls are composed entirely of metal sheets, with a distinctive projecting string course at the first-floor level. This design not only provided a modern aesthetic but also facilitated rapid construction.

Internal Layout

The internal layout of Aluminium Houses is less documented, but it is known that the homes were designed to be functional and efficient. The use of metal sheets for external walls suggests a focus on durability and ease of maintenance. However, details about internal partitions, ground and first-floor construction, and ceiling materials remain unknown.

Construction Details

Substructure

The substructure of Aluminium Houses consists of a brick underbuilding. This foundation provided stability and support for the metal frame structure above.

Frame

The main frame of the house is constructed from metal, a choice that reflects the influence of the Bristol Aeroplane Company. The use of metal framing was innovative at the time and contributed to the overall durability of the property.

Protective Coating

The protective coating used on the metal frame and external walls is not documented. However, it is likely that some form of corrosion-resistant treatment was applied to ensure the longevity of the metal components.

External Walls

The external walls are made up of storey-height metal sheets, measuring 3′ 4″ and 6′ 8″. These sheets are joined with vertical cover moulds over the vertical joints, providing a seamless and weather-resistant exterior.

Roof

The roof is covered with profiled metal sheeting, a design choice that complements the metal walls and frame. This type of roofing is known for its durability and resistance to weathering.

Typical Hazards and Risks

Corrosion

One of the primary risks associated with Aluminium Houses is corrosion. Metal components, especially those exposed to the elements, are susceptible to rust and degradation over time. This can compromise the structural integrity of the property and lead to costly repairs.

Insulation and Energy Efficiency

Given the era in which these homes were built, it is likely that they lack modern insulation and energy-efficient features. Metal walls and roofs can result in significant heat loss during the winter and overheating during the summer, leading to high energy bills and discomfort for occupants.

Structural Integrity

While the metal frame provides durability, it is essential to inspect the property for any signs of structural weakness. Over time, metal components can warp or become damaged, potentially compromising the safety of the home.

Defective Premises Act Considerations

The Aluminium House is not specifically classed as defective under the Defective Premises Act. However, given the age and unique construction of these properties, it is crucial to conduct a thorough inspection to identify any potential issues. Ensuring that the property meets modern safety and habitability standards is essential for both buyers and investors.

Inspection Guidelines for Surveyors

External Inspection

• Roof: Inspect the profiled metal sheeting for signs of rust, corrosion, or damage. Check for any leaks or areas where the roofing material may have become detached.
• Walls: Examine the metal sheets for corrosion, dents, or other damage. Pay particular attention to the vertical joints and cover moulds, as these areas may be more susceptible to wear and tear.
• Foundation: Assess the brick underbuilding for any signs of cracking, settling, or other structural issues.

Internal Inspection

• Frame: Inspect the metal frame for signs of corrosion or damage. Ensure that all components are securely fastened and free from rust.
• Partitions and Floors: While specific details about internal partitions and floors are not documented, it is essential to check for any signs of structural weakness or damage.
• Insulation: Assess the insulation levels within the property. Given the age of the home, it is likely that insulation may be inadequate by modern standards.

Safety and Compliance

• Electrical Systems: Ensure that the electrical systems meet current safety standards. Given the age of the property, it is possible that the wiring may need to be updated.
• Plumbing: Check the plumbing for any signs of leaks, corrosion, or other issues. Ensure that all fixtures and fittings are in good working order.
• Fire Safety: Assess the property for fire safety features, such as smoke detectors and fire exits. Ensure that the home meets current fire safety regulations.

Typical Defects and Maintenance Considerations

Common Defects

• Corrosion: As previously mentioned, corrosion is a significant risk for Aluminium Houses. Regular inspections and maintenance are essential to prevent rust and other forms of degradation.
• Insulation: Upgrading the insulation can significantly improve the energy efficiency and comfort of the home. Consider installing modern insulation materials in the walls, roof, and floors.
• Structural Issues: Over time, the metal frame and other components may experience wear and tear. Regular inspections can help identify and address any structural issues before they become severe.

Maintenance Tips

• Regular Inspections: Conduct regular inspections of the roof, walls, and frame to identify any signs of corrosion or damage. Address any issues promptly to prevent further deterioration.
• Protective Coatings: Consider applying a protective coating to the metal components to prevent rust and corrosion. This can significantly extend the lifespan of the property.
• Energy Efficiency Upgrades: Upgrading the insulation, windows, and doors can improve the energy efficiency of the home. This can lead to lower energy bills and a more comfortable living environment.

Conclusion

The Aluminium House is a unique and historically significant property type that offers both challenges and opportunities for home buyers and investors. While these homes are rare and may require careful maintenance, they also represent a fascinating chapter in the history of British housing. By understanding the construction details, typical hazards, and maintenance considerations, buyers and investors can make informed decisions and ensure the longevity and safety of these distinctive properties.
