Understanding the Macrae Plus House

The Macrae Plus house, a distinctive property type in the UK, offers a unique blend of architectural design and construction methodology. Developed by Hugh Macrae & Sons Ltd in the 1970s, these homes are a testament to the innovative building techniques of their time. As an expert surveyor, I will guide you through the essential aspects of these properties, from their construction characteristics to potential hazards and inspection tips.

Historical Context and Manufacturing Details

The Macrae Plus house emerged during a period of rapid housing development in the UK. In the 1970s, the demand for affordable and quickly constructed homes led to the rise of system-built properties. Hugh Macrae & Sons Ltd, a prominent manufacturer, responded to this demand by producing approximately 200 Macrae Plus houses. These homes are primarily found in suburban areas, offering a mix of semi-detached bungalows and two-storey semi-detached and terraced houses.

Design and Construction Characteristics

The Macrae Plus house is characterized by its unique design elements and construction techniques. These homes typically feature a shallow or medium pitch gable roof covered with tiles. The external walls are constructed using harled glass fibre panels, which include a wide surround to the windows. Notably, the upper panels of these homes project slightly over the lower ones, adding a distinctive architectural flair.

Construction Details

• Substructure: The specific details of the substructure are not well-documented, but it is likely to be consistent with the volumetric box construction method.
• External Walls: The walls are made from storey-height timber frame units clad with GRP (Glass Reinforced Plastic) textured finish panels. This construction method provides a lightweight yet durable exterior.
• Separating Walls and Partitions: Information on the separating walls and partitions is not readily available, but they are likely to follow standard practices of the time.
• Floors and Ceilings: Details about the ground and first floors, as well as ceilings, are not specified. However, they are expected to align with typical construction methods of the era.
• Roof: The roof construction details are not explicitly known, but the use of tiles suggests a conventional approach.

Potential Hazards and Risks

When considering a Macrae Plus house, it is crucial to be aware of potential hazards and risks associated with this property type. While these homes are not classed as defective under the Defective Premises Act, they may present certain challenges:

• Timber Frame Deterioration: As with many timber-framed houses from this period, there is a risk of timber deterioration due to moisture ingress or pest infestation. Regular inspections and maintenance are essential to mitigate these risks.
• GRP Panel Degradation: Over time, the GRP panels may degrade, leading to potential structural issues or water ingress. It is important to assess the condition of these panels during inspections.
• Thermal Efficiency: The construction materials and methods used in Macrae Plus houses may not meet modern thermal efficiency standards. Upgrading insulation and windows can improve energy efficiency.

Inspection Tips for Surveyors

Inspecting a Macrae Plus house requires a thorough understanding of its unique construction features. Here are some key points to consider during an inspection:

• Timber Frame Assessment: Examine the timber frame for signs of rot, decay, or pest damage. Pay particular attention to areas where moisture may accumulate, such as around windows and doors.
• GRP Panel Condition: Inspect the GRP panels for cracks, warping, or other signs of degradation. Ensure that the panels are securely attached to the timber frame.
• Roof and Guttering: Check the condition of the roof tiles and guttering system. Look for any signs of leaks or water damage that could affect the structural integrity of the property.
• Thermal Performance: Evaluate the insulation and glazing to determine the property’s thermal efficiency. Consider recommending upgrades to improve energy performance.

Common Defects in Macrae Plus Houses

While Macrae Plus houses offer unique architectural features, they are not without their potential defects. Understanding these common issues can help buyers and investors make informed decisions:

• Moisture Ingress: Due to the construction materials and methods, these homes may be susceptible to moisture ingress. This can lead to timber frame deterioration and other structural issues if not addressed promptly.
• Panel Degradation: The GRP panels, while durable, can degrade over time. This may result in cracks or warping, compromising the property’s exterior integrity.
• Thermal Inefficiency: As previously mentioned, the thermal performance of Macrae Plus houses may not meet modern standards. Upgrading insulation and windows can enhance energy efficiency and reduce heating costs.

Enhancing the Value of a Macrae Plus House

For buyers and investors looking to enhance the value of a Macrae Plus house, several strategies can be employed:

• Renovation and Modernization: Updating the interior and exterior of the property can significantly increase its market value. Consider modernizing the kitchen, bathrooms, and living spaces to appeal to contemporary buyers.
• Energy Efficiency Improvements: Investing in energy-efficient upgrades, such as improved insulation, double glazing, and energy-efficient heating systems, can enhance the property’s appeal and reduce utility costs.
• Regular Maintenance: Consistent maintenance is key to preserving the structural integrity and aesthetic appeal of a Macrae Plus house. Regularly inspect and address any issues with the timber frame, GRP panels, and roofing.

Navigating the Buying Process

Purchasing a Macrae Plus house involves several steps, each requiring careful consideration and due diligence:

• Property Search: Begin by identifying available Macrae Plus houses in your desired location. Work with a knowledgeable estate agent who understands the unique characteristics of these properties.
• Survey and Inspection: Engage a qualified surveyor to conduct a thorough inspection of the property. This will help identify any potential issues and provide a basis for negotiation.
• Financing and Legal Considerations: Secure financing through a mortgage lender familiar with system-built properties. Additionally, consult with a solicitor experienced in property transactions to ensure a smooth legal process.
• Negotiation and Offer: Based on the survey findings, negotiate the purchase price with the seller. Consider any necessary repairs or upgrades when making your offer.
• Completion and Handover: Once the offer is accepted, complete the legal and financial processes. Arrange for a final inspection before taking possession of the property.

Conclusion

The Macrae Plus house represents a unique opportunity for home buyers and investors in the UK. With its distinctive design and construction features, this property type offers both challenges and rewards. By understanding the potential hazards, conducting thorough inspections, and implementing strategic improvements, buyers can maximize the value and enjoyment of their Macrae Plus home.
