The Arbor House, a distinctive property type in the UK, has piqued the interest of home buyers and investors alike. Known for its unique construction and design, the Arbor House offers a blend of historical charm and modern practicality. This article delves into the essential aspects of the Arbor House, providing a detailed overview of its construction, typical characteristics, potential hazards, and inspection tips. Whether you’re considering purchasing an Arbor House or simply curious about this architectural gem, this guide will equip you with the knowledge you need.

Historical Context and Manufacturing Background

The Arbor House, also known by alternative names such as Appleyard, Lexington, Lexington Super, and New England, was manufactured by E Appleyard Ltd. This property type was predominantly built between 1965 and 1975, with approximately 1,000 units constructed during this period. These houses are typically found in suburban areas across the UK, offering a unique blend of architectural styles and construction techniques.

E Appleyard Ltd, the manufacturer behind the Arbor House, was known for its innovative approach to construction during the mid-20th century. The company focused on creating homes that were not only aesthetically pleasing but also structurally sound and energy-efficient. The Arbor House is a testament to this vision, combining traditional design elements with modern construction methods.

Typical Characteristics of the Arbor House

The Arbor House is characterized by its distinctive architectural features and construction techniques. These properties are typically bungalows or two-storey detached houses, making them suitable for a variety of living arrangements. The medium pitch gable roof, covered with interlocking concrete tiles, is a hallmark of the Arbor House design, providing both aesthetic appeal and practical benefits.

External walls of the Arbor House are often rendered with brick, horizontal plastic weatherboarding, tile hanging, or shingles, either throughout or in combination. Some houses also feature a single-storey pitched roof extension to the gable wall, adding to the property’s versatility and charm.

Construction Details

Understanding the construction details of the Arbor House is crucial for potential buyers and investors. The substructure consists of reinforced concrete (RC) perimeter beams and a concrete slab, providing a solid foundation for the property. A damp-proof course (DPC) is also included to prevent moisture ingress, ensuring the longevity of the structure.

The external walls are constructed using a platform frame method, with storey-height timber frame panels sheathed externally with plywood. This is overlaid with asphalt-impregnated breather paper and separately clad with brick or stone to the first-floor level. The walls are lined with plasterboard backed with a polyethylene vapour control layer, with insulation quilted between the frame studs. The first floor is typically clad with tile hanging or horizontal boarding, adding to the property’s visual appeal.

Partitions within the Arbor House are made of timber stud lined with plasterboard, providing a lightweight yet sturdy internal structure. The ground floor consists of chipboard on polystyrene on concrete, while the first floor features timber boarding on timber joists. Ceilings are finished with plasterboard, offering a clean and modern look.

The roof of the Arbor House is constructed using timber trusses, bituminous felt, and interlocking concrete tiles. This combination provides excellent weather resistance and durability, ensuring the property remains in good condition for years to come.

Potential Hazards and Risks

While the Arbor House offers many benefits, it’s essential to be aware of potential hazards and risks associated with this property type. One of the primary concerns is the potential for timber decay, particularly in areas where moisture ingress is a risk. Regular inspections and maintenance are crucial to prevent and address any issues related to timber decay.

Another potential risk is the presence of asbestos in some older Arbor Houses. Asbestos was commonly used in construction during the mid-20th century, and its presence can pose significant health risks if disturbed. It’s essential to have a professional survey conducted to identify and manage any asbestos-containing materials within the property.

Defective Premises Act Considerations

The Arbor House is not classed as defective under the Defective Premises Act. However, it’s essential to ensure that any property you consider purchasing meets current building regulations and standards. A thorough survey conducted by a qualified professional can help identify any potential issues and provide peace of mind.

Inspection Tips for Arbor House Buyers

When inspecting an Arbor House, there are several key areas to focus on to ensure the property is in good condition. Here are some tips to guide your inspection:

1. Roof Inspection: Check the condition of the interlocking concrete tiles and bituminous felt. Look for any signs of damage or wear, such as cracked or missing tiles, and ensure the roof is watertight.

2. External Walls: Examine the cladding materials, whether brick, weatherboarding, or shingles, for any signs of damage or deterioration. Pay particular attention to areas where different materials meet, as these can be prone to moisture ingress.

3. Timber Frame: Inspect the timber frame for any signs of decay or damage. Look for areas where moisture may have penetrated, such as around windows and doors, and ensure the timber is in good condition.

4. Insulation and Vapour Control: Check the insulation and vapour control layers within the walls. Ensure they are intact and functioning correctly to prevent heat loss and moisture ingress.

5. Asbestos Survey: If the property was built during the period when asbestos was commonly used, have a professional survey conducted to identify any asbestos-containing materials.

6. Foundation and Substructure: Examine the RC perimeter beams and concrete slab for any signs of cracking or movement. Ensure the damp-proof course is intact and functioning correctly.

7. Internal Partitions and Ceilings: Check the condition of the plasterboard linings and ceilings. Look for any signs of damage, such as cracks or water stains, and ensure they are in good condition.

8. Flooring: Inspect the ground and first-floor materials for any signs of wear or damage. Ensure the chipboard, polystyrene, and timber boarding are in good condition and free from moisture damage.

Typical Defects in Arbor Houses

While the Arbor House is generally well-constructed, there are some common defects to be aware of. These include:

• Timber Decay: As mentioned earlier, timber decay is a potential risk, particularly in areas where moisture ingress is a concern. Regular inspections and maintenance can help prevent and address this issue.

• Asbestos: The presence of asbestos in some older Arbor Houses can pose significant health risks. It’s essential to have a professional survey conducted to identify and manage any asbestos-containing materials.

• Moisture Ingress: Moisture ingress can lead to a range of issues, including timber decay, mould growth, and structural damage. Ensuring the property is watertight and well-maintained can help prevent these problems.

• Roof Damage: The interlocking concrete tiles and bituminous felt on the roof can become damaged over time, leading to leaks and water ingress. Regular inspections and maintenance can help identify and address any issues.

• Insulation and Vapour Control Issues: Poor insulation and vapour control can lead to heat loss and moisture ingress. Ensuring these elements are intact and functioning correctly is crucial for maintaining the property’s energy efficiency and structural integrity.

Conclusion

The Arbor House is a unique and appealing property type that offers a blend of historical charm and modern practicality. Understanding its construction, typical characteristics, potential hazards, and inspection tips can help you make an informed decision when considering a purchase. By being aware of the common defects and taking steps to address them, you can ensure your Arbor House remains a safe and comfortable home for years to come.
