Understanding the Telford House

The Telford house, a distinctive architectural marvel, stands as a testament to the ingenuity of early 20th-century construction. Built in 1924 by Braithwaite & Co. Ltd, these homes are a unique part of the UK’s housing history. With only 300 units constructed, they are a rare find for home buyers and investors alike. Known alternatively as the Braithwaite or Braithwaite Unit Frame, these properties are primarily located in areas that embraced industrial innovation during the early 1900s.

Design and Construction

The Telford house is a two-storey semi-detached property, characterized by its medium pitch hipped roof, which is typically covered with steel panels or plain clay tiles. The external walls are made of storey-height flat steel panels, featuring rounded corners and a projecting band course at the first-floor level. A single-storey bay window adds to the aesthetic appeal of these homes.

The construction of Telford houses is a fascinating blend of materials and techniques. The substructure consists of a concrete trench fill incorporating a ground floor slab, with a raised and splayed perimeter kerb and apron. The external walls are composed of tray-like storey-height steel panels, bolted together through flanges. These panels are complemented by timber framing tied to the panels with metal straps and lined with asbestos cement sheets.

Typical Characteristics and Hazards

While the Telford house boasts a unique design, it also presents certain challenges. One of the most significant issues is the severe corrosion of steel panels, particularly at the bases. This corrosion extends to the panel fixing bolts and the expansion of joints between panels. Superficial corrosion can also be found on the backs of panels and in the roof space steelwork. Additionally, the wall panels may exhibit a bow, and there can be cracked and broken concrete kerbs, as well as rot in the timber framing and ground floor boarding.

Defective Premises Act Considerations

When considering the purchase of a Telford house, it is crucial to understand its classification under the Defective Premises Act. While these homes are not universally classified as defective, the potential for structural issues due to corrosion and material degradation means that a thorough inspection is essential. Engaging a professional surveyor to assess the condition of the property can help identify any defects and inform your decision-making process.

Inspection Tips for Telford Houses

Inspecting a Telford house requires a keen eye and attention to detail. Here are some key areas to focus on during your inspection:

1. Steel Panels: Check for signs of corrosion, particularly at the base of the panels and around fixing bolts. Look for any expansion or separation at the joints.

2. Roof Space: Inspect the steelwork in the roof space for superficial corrosion. Ensure that the roof covering, whether steel panels or clay tiles, is intact and free from leaks.

3. Wall Panels: Examine the wall panels for any bowing or deformation. Pay attention to the condition of the projecting band course at the first-floor level.

4. Timber Framing: Look for signs of rot in the timber framing, especially around the ground floor boarding. Ensure that the timber is securely tied to the steel panels.

5. Concrete Kerbs and Aprons: Check for cracks or breaks in the concrete kerbs and aprons. These can indicate underlying structural issues.

6. Asbestos Cement Sheets: Be aware of the presence of asbestos cement sheets in the construction. While not immediately hazardous, any renovation work should be conducted with caution and in compliance with safety regulations.

Construction Details

The construction of Telford houses is a blend of innovative techniques and materials. The substructure features a concrete trench fill with a ground floor slab, providing a solid foundation. The external walls are composed of tray-like storey-height steel panels, bolted together through flanges. These panels are complemented by timber framing tied to the panels with metal straps and lined with asbestos cement sheets.

The separating wall consists of double cavity timber stud frames lined with asbestos cement sheets, with a central leaf of storey-height steel panels. Partitions are made of timber stud lined with asbestos cement sheets, with steel panels in the kitchen and coal store area.

The ground floor is constructed of concrete, with living room T&G boarding on timber battens bedded in concrete. The first floor features T&G boarding on flitched timber joists, while the ceilings are lined with asbestos cement sheets. The roof is supported by RSA ties and steel panels, with some variants featuring RSA purlins, timber rafters, and plain clay tiles.

Common Defects in Telford Houses

Despite their historical significance, Telford houses are not without their flaws. Common defects include:

• Corrosion: As previously mentioned, corrosion of steel panels and fixing bolts is a prevalent issue. This can lead to structural instability if not addressed promptly.

• Bowing Wall Panels: The steel panels may bow over time, compromising the structural integrity of the property.

• Rot in Timber Framing: Timber framing is susceptible to rot, particularly in areas exposed to moisture. This can weaken the overall structure and lead to further issues.

• Cracked Concrete Kerbs: Cracks in the concrete kerbs and aprons can indicate underlying structural problems and should be investigated thoroughly.

• Asbestos Concerns: The presence of asbestos cement sheets in the construction poses a potential health risk if disturbed. Proper handling and disposal are essential during any renovation work.

Variants and Modifications

Over the years, some Telford houses have undergone modifications to address these common defects. For instance, some properties have been re-roofed with interlocking concrete tiles, providing a more durable and weather-resistant covering. Additionally, the use of concrete slab foundations has been implemented in some variants to enhance stability.

Investing in a Telford House

For investors, the Telford house presents both opportunities and challenges. The unique design and historical significance of these properties can make them attractive to buyers seeking a distinctive home. However, the potential for structural issues and the need for ongoing maintenance should be carefully considered.

When investing in a Telford house, it is essential to conduct a thorough inspection and engage a professional surveyor to assess the property’s condition. This will help identify any defects and inform your investment strategy. Additionally, consider the potential for renovation and modernization to enhance the property’s value and appeal.

Renovation and Modernization Tips

If you decide to invest in a Telford house, renovation and modernization can significantly enhance its value and appeal. Here are some tips to consider:

1. Address Structural Issues: Prioritize addressing any structural issues, such as corrosion, bowing wall panels, and rot in timber framing. This will ensure the property’s long-term stability and safety.

2. Upgrade Roofing: Consider re-roofing with interlocking concrete tiles for improved durability and weather resistance. This can also enhance the property’s aesthetic appeal.

3. Asbestos Management: If asbestos cement sheets are present, ensure proper handling and disposal during renovation work. Engage a professional to manage this process safely.

4. Modernize Interiors: Update the interior spaces with modern finishes and fixtures to enhance the property’s appeal to potential buyers or tenants.

5. Energy Efficiency: Consider incorporating energy-efficient features, such as improved insulation and double-glazed windows, to reduce energy costs and increase the property’s value.

Conclusion

The Telford house is a unique and historically significant property type that offers both opportunities and challenges for home buyers and investors. Understanding the construction, typical characteristics, and potential defects of these homes is essential for making informed decisions. By conducting a thorough inspection and considering renovation and modernization options, you can unlock the full potential of a Telford house and ensure a sound investment.
