Understanding the Burt Boulton House

The Burt Boulton house, a distinctive property type in the UK, offers a unique glimpse into the architectural and construction practices of the mid-1970s. Designed by H K Harwood and manufactured by Burt Boulton Ltd, these homes were primarily built in 1975. They are a testament to the era’s innovative approach to residential construction, combining functionality with a modern aesthetic. This article delves into the essential aspects of the Burt Boulton house, providing valuable insights for potential home buyers and investors.

Historical Context and Manufacturing Details

The Burt Boulton house emerged during a period of rapid development in the UK housing market. In 1975, the demand for affordable and efficient housing solutions led to the creation of these system-built properties. Burt Boulton Ltd, a prominent manufacturer, played a pivotal role in meeting this demand. The company was known for its expertise in timber construction, which was a popular choice due to its cost-effectiveness and sustainability.

These houses were primarily constructed as bungalows and two-storey detached, semi-detached, and terraced homes. The design incorporated a shallow pitch gable or monopitch roof, covered with tiles or bituminous felt. Some variants featured a flat roof with bituminous felt. The external walls were typically rendered plywood, with some homes showcasing tile hanging above the first floor level. A distinctive feature panel of horizontal or vertical timber boarding was often placed adjacent to the front door, adding a touch of character to the façade.

Architectural Characteristics and Design Features

The Burt Boulton house is characterized by its volumetric box construction, a method that allowed for efficient assembly and cost savings. The external walls were constructed using storey-height timber frame units, overlaid with sisalcraft paper and directly clad with rendered plywood. This design provided a robust and weather-resistant exterior, essential for the UK’s variable climate.

Internally, the houses were lined with foil-backed plasterboard, offering additional insulation and a smooth finish. Mineral fibre insulation was placed between the frame studs, enhancing the thermal efficiency of the property. The separating walls featured a timber frame cavity, backed with asbestos cement sheets and lined with plasterboard. This construction method provided sound insulation and fire resistance, crucial for multi-storey dwellings.

The ground floor was typically constructed with plywood on timber joists, while the first floor utilized plywood on double timber joists. Ceilings were finished with plasterboard, conforming to the roof pitch on the first floor. The roof itself was supported by timber rafters, with plywood decking and bituminous felt providing a durable and weatherproof covering.

Potential Hazards and Risks

While the Burt Boulton house offers numerous advantages, potential buyers and investors should be aware of certain hazards and risks associated with this property type. One of the primary concerns is the presence of asbestos cement sheets in the separating walls. Asbestos, a common building material in the past, poses significant health risks if disturbed. It is crucial to conduct a thorough inspection to identify and manage any asbestos-containing materials.

Another potential issue is the condition of the rendered plywood cladding. Over time, exposure to the elements can lead to deterioration, resulting in water ingress and structural damage. Regular maintenance and timely repairs are essential to preserve the integrity of the cladding and prevent costly repairs.

Defective Premises Act Considerations

The Defective Premises Act 1972 imposes a duty on builders and developers to ensure that properties are constructed to a reasonable standard. While the Burt Boulton house is not specifically classified as defective under this act, it is essential to conduct a comprehensive survey to identify any potential defects or issues. Engaging a qualified surveyor can provide peace of mind and ensure that the property meets current safety and quality standards.

Inspection and Assessment Guidelines

When inspecting a Burt Boulton house, it is crucial to follow a systematic approach to identify any potential issues. The following guidelines can assist in conducting a thorough assessment:

1. Exterior Inspection: Begin by examining the external walls for signs of damage or deterioration. Pay particular attention to the rendered plywood cladding and tile hanging, checking for cracks, warping, or water stains. Inspect the roof for missing or damaged tiles and ensure that the bituminous felt is intact.

2. Interior Assessment: Inside the property, inspect the plasterboard linings for any signs of moisture damage or mould growth. Check the condition of the mineral fibre insulation and ensure that it is adequately installed between the frame studs. Examine the separating walls for any visible signs of asbestos cement sheets and consider professional testing if necessary.

3. Structural Evaluation: Assess the condition of the timber frame units and joists, looking for signs of rot, insect infestation, or structural weakness. Pay attention to the ground and first-floor construction, ensuring that the plywood and timber joists are in good condition.

4. Roof Inspection: Inspect the roof structure, including the timber rafters and plywood decking. Check for any signs of sagging, water damage, or leaks. Ensure that the bituminous felt is securely attached and free from tears or punctures.

5. Utilities and Services: Evaluate the condition of the property’s utilities, including plumbing, electrical, and heating systems. Ensure that they are in good working order and comply with current safety standards.

Common Defects and Maintenance Tips

The Burt Boulton house, like any property, may experience common defects over time. Being aware of these issues and implementing regular maintenance can help preserve the property’s value and functionality.

1. Cladding Maintenance: Regularly inspect the rendered plywood cladding for signs of wear and tear. Address any cracks or damage promptly to prevent water ingress and further deterioration. Consider applying a weatherproof sealant to enhance the cladding’s durability.

2. Asbestos Management: If asbestos cement sheets are present, it is crucial to manage them safely. Avoid disturbing the material and seek professional advice for removal or encapsulation if necessary. Regular monitoring and maintenance can help mitigate the risks associated with asbestos.

3. Roof Repairs: Inspect the roof regularly for missing or damaged tiles and ensure that the bituminous felt is intact. Address any leaks or water damage promptly to prevent further issues. Consider professional roof maintenance to extend the lifespan of the roof covering.

4. Insulation Upgrades: Evaluate the condition of the mineral fibre insulation and consider upgrading to modern, energy-efficient materials if necessary. Proper insulation can enhance the property’s thermal performance and reduce energy costs.

5. Structural Integrity: Regularly assess the condition of the timber frame units and joists for signs of rot or insect infestation. Implement necessary repairs or treatments to maintain the structural integrity of the property.

Conclusion

The Burt Boulton house represents a unique chapter in the UK’s architectural history, offering a blend of functionality and modern design. While these properties present certain challenges, a thorough understanding of their construction and potential issues can empower buyers and investors to make informed decisions. By conducting comprehensive inspections and implementing regular maintenance, the Burt Boulton house can continue to provide a comfortable and sustainable living environment for years to come.
