Historical Context and Manufacturing

The Farrans No-Fines house, a notable example of post-war British architecture, emerged in the 1960s as a solution to the housing crisis. These properties were primarily constructed by Farrans Construction, a company renowned for its innovative building techniques. The term “No-Fines” refers to the unique concrete mix used in the construction, which excluded fine aggregates like sand, resulting in a porous yet robust material.

These houses were predominantly built in urban and suburban areas across the UK, with approximately 1,000 units constructed during this period. The design aimed to provide affordable, durable housing quickly and efficiently, addressing the urgent need for homes in the post-war era.

Identifying Characteristics

Farrans No-Fines houses are typically two-storey terraced properties. They feature a medium-pitch roof covered with tiles and external walls rendered throughout. The absence of fine aggregates in the concrete mix gives the walls a distinctive texture, making these houses relatively easy to identify.

Key Features:

• Two-storey terraced design
• Medium-pitch tiled roof
• Rendered external walls with a unique texture

Construction Details

Understanding the construction details of Farrans No-Fines houses is crucial for potential buyers and investors. These properties have several unique characteristics that set them apart from traditional brick-and-mortar homes.

Substructure

The substructure of Farrans No-Fines houses is not well-documented, which can pose challenges during inspections. However, the primary focus should be on the condition of the concrete and any signs of structural issues.

External Walls

The external walls are constructed using no-fines concrete, a mix that excludes fine aggregates. This type of concrete is porous, allowing for better insulation and moisture control. However, it can also be more susceptible to certain types of damage, such as cracking and spalling.

Separating Walls and Partitions

Details about the separating walls and internal partitions are not well-documented. During an inspection, it is essential to assess these areas for any signs of structural weakness or damage.

Ground and First Floors

Information about the ground and first floors is limited. Inspectors should pay close attention to the condition of the flooring, looking for any signs of wear, damage, or structural issues.

Ceilings

The construction details of the ceilings are not well-documented. Inspectors should check for any signs of sagging, water damage, or other issues that could indicate underlying problems.

Roof

The roof of Farrans No-Fines houses typically consists of timber purlins, rafters, and tiles. Inspectors should assess the condition of the roof, looking for any signs of damage, wear, or potential leaks.

Typical Hazards and Risks

While Farrans No-Fines houses were designed to be durable and affordable, they are not without their risks and hazards. Potential buyers and investors should be aware of these issues to make informed decisions.

Structural Issues

The unique no-fines concrete used in these houses can be prone to cracking and spalling. Over time, this can lead to structural weaknesses that may require significant repairs.

Moisture and Insulation

The porous nature of no-fines concrete can lead to moisture ingress, which can cause dampness and mould issues. Proper insulation and ventilation are crucial to mitigate these risks.

Roof and Timber Decay

The timber components of the roof can be susceptible to decay, especially if they have been exposed to moisture. Regular inspections and maintenance are essential to prevent significant damage.

Defective Premises Act

Farrans No-Fines houses are not classified as defective under the Defective Premises Act. However, potential buyers should still conduct thorough inspections to identify any issues that may require attention.

Inspection Guide for Surveyors

When inspecting a Farrans No-Fines house, surveyors should follow a systematic approach to ensure all potential issues are identified and assessed.

External Inspection

1. Walls: Examine the external walls for any signs of cracking, spalling, or other damage. Pay close attention to the texture of the no-fines concrete.
2. Roof: Inspect the roof for any signs of damage, wear, or potential leaks. Check the condition of the tiles, timber purlins, and rafters.
3. Windows and Doors: Assess the condition of the windows and doors, looking for any signs of wear, damage, or poor insulation.

Internal Inspection

1. Walls and Partitions: Check the internal walls and partitions for any signs of structural weakness or damage. Look for cracks, dampness, or other issues.
2. Floors: Examine the ground and first floors for any signs of wear, damage, or structural issues. Pay close attention to the condition of the flooring materials.
3. Ceilings: Inspect the ceilings for any signs of sagging, water damage, or other issues that could indicate underlying problems.
4. Moisture and Insulation: Assess the property for any signs of moisture ingress, dampness, or mould. Check the insulation and ventilation to ensure they are adequate.

Additional Considerations

1. Structural Integrity: Pay close attention to the overall structural integrity of the property. Look for any signs of significant damage or wear that may require repairs.
2. Maintenance History: Review the maintenance history of the property, if available. This can provide valuable insights into any past issues and repairs.
3. Compliance with Building Regulations: Ensure the property complies with current building regulations and standards. This is especially important for older properties that may not meet modern requirements.
