Swift House: A Comprehensive Guide for Home Buyers and Investors

The Swift House, a notable example of system-built properties in the UK, offers a unique blend of architectural design and construction techniques. As an expert surveyor, I will guide you through the essential aspects of this property type, from its historical context to its construction details, potential hazards, and inspection tips. Whether you’re a home buyer or an investor, understanding the intricacies of the Swift House can help you make informed decisions.

Historical Context and Manufacturers

The Swift House was manufactured between 1965 and 1970, a period marked by a surge in demand for affordable housing solutions. This demand led to the development of system-built properties, which were designed to be constructed quickly and efficiently. Swift Homes Ltd and Netherton Building and Construction Co. Ltd were the primary manufacturers of these properties, with designs that catered to the needs of the time.

These houses are also known by the alternative name “Sharen” and were primarily built as detached bungalows, chalet bungalows, and two-storey detached houses. The design and construction of Swift Houses reflect the architectural trends of the late 1960s, with a focus on functionality and cost-effectiveness.

Identification Characteristics

Swift Houses are easily identifiable by their distinct architectural features. They typically have steep, medium, or shallow pitch gable roofs covered with tiles or asphalt shingles. The roofs often have large overhangs at the eaves and gables, providing a characteristic silhouette.

The external walls are usually constructed of brick, with gable wall feature panels of horizontal timber boarding. In some cases, the walls are clad with cedar shingles, adding a rustic charm to the property. Bungalow gable walls may be partially clad with vertical timber boarding, and some chalet bungalows feature a flat canopy over the front door.

Construction Details

Understanding the construction details of Swift Houses is crucial for assessing their condition and potential risks. Here’s a breakdown of the typical construction elements:

• Substructure: The foundation is typically made of concrete strip footings with brick under-building and a damp-proof course (DPC) to prevent moisture ingress.

• External Walls: The walls are constructed using a platform frame method, with storey-height timber frame panels sheathed externally with fibreboard. These panels are separately clad with brick and lined with foil-backed plasterboard. Glass fibre insulation is placed between the frame studs for thermal efficiency.

• Partitions: Internal partitions are made of timber studs lined with plasterboard, with mineral wool blankets between the frame studs for sound insulation.

• Floors: The ground and first floors are constructed with plywood on timber joists, providing a stable and durable surface.

• Ceilings: Ceilings are typically made of fibreboard, offering a lightweight and cost-effective solution.

• Roof: The roof structure consists of timber trusses, bituminous felt, and tiles, with a glass fibre quilt at ceiling level for insulation.

Variants

Some Swift Houses may feature variations in their construction, such as:

• Concrete raft foundations instead of strip footings.
• Gable walls partially clad with vertical timber boarding.
• Ground floors made of plywood on concrete.
• Roofs with timber trusses, plywood decking, bituminous felt, and asphalt shingles.
• Steep or medium pitch gable roofs.

Typical Hazards and Risks

While Swift Houses offer many benefits, they also come with certain hazards and risks that potential buyers and investors should be aware of:

• Timber Frame Deterioration: Over time, the timber frame can be susceptible to rot and decay, especially if exposed to moisture. Regular inspections and maintenance are essential to prevent structural issues.

• Insulation and Energy Efficiency: The original insulation materials used in Swift Houses may not meet modern energy efficiency standards. Upgrading the insulation can improve thermal performance and reduce energy costs.

• Roofing Issues: The roofing materials, particularly asphalt shingles, may degrade over time, leading to leaks and water damage. Regular roof inspections and timely repairs are crucial to maintaining the property’s integrity.

• Asbestos Concerns: Some Swift Houses may contain asbestos in the construction materials, particularly in the fibreboard or insulation. It’s important to conduct an asbestos survey and, if necessary, arrange for safe removal by a licensed professional.

Defective Premises Act

The Swift House is not classed as defective under the Defective Premises Act. However, it’s important to note that this does not exempt the property from potential issues related to its construction and materials. Regular inspections and maintenance are key to ensuring the property’s safety and longevity.

Inspection Tips for Swift Houses

When inspecting a Swift House, it’s important to focus on specific areas that are prone to issues. Here are some tips to guide your inspection:

• Foundation and Substructure: Check for signs of subsidence or movement in the foundation. Look for cracks in the brickwork or uneven floors, which may indicate structural issues.

• External Walls: Inspect the condition of the brick cladding and timber boarding. Look for signs of rot, decay, or insect infestation in the timber elements.

• Roof and Guttering: Examine the roof for missing or damaged tiles or shingles. Check the condition of the guttering and downpipes to ensure proper drainage and prevent water ingress.

• Insulation and Ventilation: Assess the insulation in the walls and roof. Ensure that there is adequate ventilation to prevent condensation and mould growth.

• Asbestos Survey: If the property was built before the 1980s, consider conducting an asbestos survey to identify any hazardous materials.

• Electrical and Plumbing Systems: Check the condition of the electrical wiring and plumbing systems. Look for signs of wear and tear, and ensure that they meet current safety standards.

Conclusion

The Swift House represents a unique chapter in the history of UK housing, offering a blend of architectural charm and practical design. While these properties come with certain risks and challenges, they also offer opportunities for renovation and improvement. By understanding the construction details, potential hazards, and inspection tips, home buyers and investors can make informed decisions and safeguard their investments.
