Understanding the Forfar Borough House

The Forfar Borough house, a distinctive architectural design from the mid-20th century, stands as a testament to the innovative construction methods of its time. Built in 1965, these properties are primarily located in the UK, with a total of 100 units constructed. Designed by the Forfar Borough Architect, these homes are a unique blend of style and functionality, offering a glimpse into the architectural trends of the 1960s.

Manufacturers and Designers

The Forfar Borough house was a product of collaboration between skilled manufacturers and visionary designers. The Forfar Borough Architect played a pivotal role in shaping the design, ensuring that each home met the aesthetic and functional needs of the era. The construction was carried out by local builders who adhered to the specifications laid out by the architect, ensuring consistency across all units.

Typical Characteristics of the Forfar Borough House

These properties are easily identifiable by their two-storey terraced design. The medium pitch gable roof, covered with concrete tiles, is a signature feature. The front and rear external walls are rendered throughout, with a granite composite brick pier at the separating wall. The gable wall is also constructed from granite composite bricks, adding to the structural integrity and aesthetic appeal of the house. A single-storey flat roof entrance lobby provides a welcoming entry point to the home.

Potential Hazards and Risks

While the Forfar Borough house boasts a robust design, it is not without its potential hazards. One of the primary concerns is the risk of interstitial condensation, which can lead to moisture build-up within the walls. This can cause structural damage over time if not addressed promptly. Additionally, the differential movement at first-floor windows and the bridging of the damp-proof course (DPC) by render are issues that require careful monitoring.

Defective Premises Act Considerations

Under the Defective Premises Act, properties must meet certain standards to ensure the safety and well-being of occupants. The Forfar Borough house, while not inherently defective, does present some challenges that need to be addressed to comply with modern safety standards. Regular inspections and maintenance are crucial to identifying and rectifying any potential issues before they escalate.

Inspection Guide for Surveyors

When inspecting a Forfar Borough house, surveyors should pay close attention to several key areas. Start by examining the first-floor windows for signs of differential movement. This can indicate underlying structural issues that need to be addressed. Check the render for spalling, which can compromise the integrity of the external walls. Additionally, inspect the DPC to ensure it is not bridged by render, as this can lead to moisture ingress.

Typical Construction Features

The construction of the Forfar Borough house is a fascinating blend of traditional and modern techniques. The substructure consists of concrete strip footings with a vented block underbuilding. The external walls are of balloon frame construction, with eaves height timber frame panels overlaid with building paper. These are separately clad with rendered brick at the front and rear walls and with granite composite brick at the gable wall. The walls are lined with foil-backed plasterboard, providing additional insulation and moisture resistance.

The separating wall is an 11-inch cavity block wall lined with plasterboard on timber battens, ensuring sound insulation between units. Internal partitions are constructed from timber stud lined with plasterboard, offering flexibility in interior design.

Flooring and Ceilings

The ground floor features chipboard on timber joists, with concrete in the fuel store for added durability. The first floor also uses chipboard on timber joists, providing a consistent aesthetic throughout the home. Ceilings are made from plasterboard, with foil-backed plasterboard used in the roof space to enhance insulation.

Roof Construction

The roof of the Forfar Borough house is constructed using timber trusses and timber sarking, covered with bituminous felt and concrete tiles. Mineral fibre insulation is installed at ceiling level, ensuring energy efficiency and comfort for occupants.

Common Defects in Forfar Borough Houses

Despite their robust construction, Forfar Borough houses are susceptible to certain defects. Spalling of render is a common issue, often caused by moisture ingress or freeze-thaw cycles. This can lead to unsightly damage and potential structural concerns if not addressed. Differential movement at first-floor windows is another common defect, often resulting from settlement or thermal expansion and contraction.

Addressing Interstitial Condensation

Interstitial condensation is a significant concern in Forfar Borough houses. This occurs when warm, moist air penetrates the building envelope and condenses within the wall cavity. Over time, this can lead to mould growth, timber decay, and structural damage. To mitigate this risk, ensure that the building envelope is properly sealed and ventilated. Installing vapour barriers and improving insulation can also help prevent condensation.

Maintaining the Damp-Proof Course

The damp-proof course (DPC) is a critical component in preventing moisture ingress. In Forfar Borough houses, the DPC is often bridged by render, which can lead to moisture penetration. Regular inspections and maintenance are essential to ensure the DPC remains effective. If bridging is detected, remedial work should be carried out promptly to prevent further damage.

Enhancing Energy Efficiency

While the Forfar Borough house was designed with energy efficiency in mind, there are several modern upgrades that can further enhance its performance. Installing double-glazed windows and doors can significantly reduce heat loss, while adding additional insulation to the roof and walls can improve thermal performance. Upgrading to energy-efficient heating systems and appliances can also reduce energy consumption and lower utility bills.

Preserving the Architectural Integrity

When undertaking renovations or repairs on a Forfar Borough house, it is important to preserve its architectural integrity. This includes maintaining the original design features, such as the medium pitch gable roof and granite composite brickwork. Any alterations should be sympathetic to the original design, ensuring that the property retains its historical and aesthetic value.

Navigating Planning Permissions

Before undertaking any major renovations or extensions, it is important to check whether planning permission is required. The Forfar Borough house, being a historical property, may be subject to specific planning regulations. Consulting with local planning authorities and obtaining the necessary permissions can help avoid potential legal issues and ensure that any work carried out is compliant with local regulations.

Investing in a Forfar Borough House

For investors, the Forfar Borough house presents a unique opportunity. These properties are not only a piece of architectural history but also offer potential for capital growth. With the right renovations and maintenance, a Forfar Borough house can be a valuable addition to any property portfolio. However, it is important to conduct thorough due diligence and inspections to ensure that any potential issues are identified and addressed before purchase.

The Role of a Professional Surveyor

Engaging a professional surveyor is crucial when purchasing a Forfar Borough house. A surveyor can provide a detailed assessment of the property’s condition, identifying any defects or potential issues. This information is invaluable in making an informed purchasing decision and ensuring that the property is a sound investment.

Conclusion

The Forfar Borough house is a unique and historically significant property type that offers both challenges and opportunities for home buyers and investors. By understanding its construction, potential defects, and maintenance requirements, you can make informed decisions and ensure the longevity and value of your investment.
