Unveiling the Stewart & Lloyd House: A Comprehensive Guide for UK Home Buyers and Investors

Understanding the Stewart & Lloyd House

The Stewart & Lloyd house, a unique architectural relic from the mid-20th century, stands as a testament to post-war ingenuity in the UK. These properties, though few in number, offer a fascinating glimpse into the era’s construction methodologies and the challenges they present to modern homeowners and investors. This article delves into the intricacies of the Stewart & Lloyd house, providing a detailed examination of its construction, potential hazards, and considerations for prospective buyers.

Historical Context and Manufacturing Background

The Stewart & Lloyd house was manufactured in 1945, a period marked by a pressing need for rapid housing solutions following World War II. Stewart & Lloyd Ltd, in collaboration with designers Arcorn Ltd, embarked on creating these homes to address the housing shortage. Only two of these properties were built, making them rare and intriguing finds for property enthusiasts.

These houses are typically located in areas that experienced significant wartime damage, where quick and efficient housing solutions were paramount. The Stewart & Lloyd house, also known as the Lloyd house, is a semi-detached, two-storey structure that reflects the architectural and material constraints of its time.

Construction Characteristics and Materials

The Stewart & Lloyd house is characterized by its medium pitch gable roof, covered with concrete tiles. The external walls are constructed using pre-cast reinforced concrete (PRC) panels up to the first-floor level, with profiled asbestos cement sheets above. This combination of materials was chosen for its cost-effectiveness and ease of assembly, crucial factors in the post-war housing boom.

The frame of the house is a complex assembly of tubular steel stanchions, perimeter beams, and lattice steel floor support beams. Tubular steel roof trusses and bracings provide additional structural integrity. However, the protective coating used on these steel components remains unknown, which can pose a risk of corrosion over time.

Internally, the partitions are made from timber framing infilled with woodwool slabs and lined with plasterboard. This construction method was typical of the era, offering a balance between insulation and structural support.

Potential Hazards and Risks

While the Stewart & Lloyd house is a fascinating piece of architectural history, it is not without its risks. The use of asbestos cement sheets in the construction poses a significant health hazard if disturbed. Asbestos, when airborne, can lead to serious respiratory issues, making it imperative for homeowners to handle any renovations or repairs with extreme caution.

Additionally, the reliance on steel components, without a known protective coating, raises concerns about corrosion. Over time, this can compromise the structural integrity of the house, leading to costly repairs or even rendering the property unsafe.

The PRC panels used in the construction are also a point of concern. These panels can deteriorate over time, particularly if exposed to moisture, leading to structural weaknesses. As such, regular inspections and maintenance are crucial to ensure the longevity and safety of the property.

Legal Considerations: Defective Premises Act

The Stewart & Lloyd house is not classified as defective under the Defective Premises Act. However, this does not exempt it from scrutiny. Prospective buyers should be aware of the potential issues associated with the materials and construction methods used in these houses. A thorough survey by a qualified professional is essential to identify any existing or potential defects.

Inspection Guide for Prospective Buyers

When inspecting a Stewart & Lloyd house, there are several key areas to focus on:

1. Roof and External Walls: Check for any signs of damage or wear in the concrete tiles and asbestos cement sheets. Look for cracks, missing tiles, or any evidence of water ingress.
2. Steel Frame: Inspect the steel components for signs of corrosion. Pay particular attention to areas where the protective coating may have worn away, exposing the steel to the elements.
3. PRC Panels: Examine the PRC panels for any signs of deterioration, such as cracking or spalling. Moisture ingress can accelerate the degradation of these panels, so ensure that any potential entry points for water are sealed.
4. Asbestos Management: If any asbestos-containing materials are present, ensure they are in good condition and not disturbed. Consider hiring a specialist to assess and manage any asbestos risks.
5. Internal Partitions: Check the condition of the timber framing and woodwool slabs. Look for any signs of rot or damage that could compromise the structural integrity of the partitions.

Construction Details: A Closer Look

The construction of the Stewart & Lloyd house is a fascinating study in post-war building techniques. The substructure remains unknown, but the superstructure is a testament to the ingenuity of the era.

• Frame: The use of a setting out jig, tubular steel stanchions, and perimeter beams provided a robust framework for the house. The lattice steel floor support beams and roof trusses added additional strength and stability.
• External Walls: The combination of PRC panels and asbestos cement sheets was a practical solution for the time, offering both durability and ease of construction.
• Partitions and Ceilings: The timber framing and woodwool slabs used in the internal partitions provided a lightweight yet effective solution for dividing the internal space. The plasterboard lining offered a smooth finish, ready for decoration.
• Roof: The concrete tiles used on the roof were a common choice in the post-war period, offering a durable and weather-resistant covering.

Common Defects and Maintenance Tips

Despite their historical significance, Stewart & Lloyd houses are prone to certain defects. Regular maintenance and timely repairs are essential to preserve these unique properties.

• Corrosion of Steel Components: Regular inspections are crucial to identify any signs of corrosion. Applying a protective coating can help prevent further deterioration.
• Deterioration of PRC Panels: Keep an eye out for any signs of cracking or spalling. Address any moisture ingress issues promptly to prevent further damage.
• Asbestos Management: If asbestos-containing materials are present, ensure they are in good condition and not disturbed. Consider professional removal if necessary.
• Roof Maintenance: Regularly inspect the roof for any missing or damaged tiles. Promptly replace any that are compromised to prevent water ingress.

Conclusion

The Stewart & Lloyd house is a unique piece of architectural history, offering both challenges and opportunities for modern homeowners and investors. Understanding the construction methods and potential risks associated with these properties is crucial for making informed decisions. With careful inspection and maintenance, these houses can continue to stand as a testament to post-war ingenuity for years to come.
