Understanding the Scano Type II House

The Scano Type II house, a unique architectural gem, stands as a testament to the innovative spirit of early 20th-century British construction. Designed by the London County Council and manufactured by Scanhouse Ltd, these houses were built in 1925. Only two of these distinctive properties were ever constructed, making them a rare find in the UK property market. Known alternatively as LCC Timber or simply Scano, these houses are a fascinating study for home buyers and investors alike.

Historical Context and Manufacturing Details

The Scano Type II house emerged during a period of experimentation in building techniques and materials. The post-World War I era saw a surge in demand for housing, prompting architects and builders to explore new methods of construction. The London County Council, a key player in urban development, collaborated with Scanhouse Ltd to create these innovative homes. The aim was to provide affordable, durable housing that could be quickly assembled, a necessity in the rapidly expanding urban landscape of the time.

Architectural Characteristics

The Scano Type II house is a three-storey detached property, characterized by its steep pitch gable or mansard roof covered with tiles. The external walls are rendered with pebbledash, featuring inband-outband quoins that add a touch of elegance to the structure. One of the two houses boasts a shallow pitch dormer window above the central front door, a distinctive feature that sets it apart.

Construction Details

The construction of the Scano Type II house is a marvel of engineering for its time. The substructure consists of concrete strip footings and a concrete perimeter basement wall that extends two feet above ground level. A damp-proof course (DPC) is incorporated to prevent moisture ingress.

The external walls are built using a platform frame construction method. Storey-height timber frame panels are sheathed externally with tongue-and-groove (T&G) horizontal timber boarding, overlaid with bituminous paper. This is directly clad with render on wire mesh, supported by timber battens on T&G vertical timber boarding, and lined with plasterboard.

Internally, the partitions are made of timber stud lined with plasterboard. The ground and first floors feature T&G boarding on timber joists, while the ceilings are finished with plasterboard. The roof structure comprises timber rafters, T&G timber boarding, timber battens, and tiles.

Potential Hazards and Risks

While the Scano Type II house is a remarkable example of early 20th-century construction, it is not without its potential hazards and risks. As with many timber-framed houses of this era, issues such as wood rot, insect infestation, and structural movement can arise. The use of bituminous paper in the wall construction may also pose a risk of moisture ingress if not properly maintained.

Defective Premises Act Considerations

The Scano Type II house is not classified as defective under the Defective Premises Act. However, given its age and unique construction, it is essential for potential buyers and investors to conduct thorough inspections to identify any underlying issues. Engaging a professional surveyor with expertise in timber-framed houses is highly recommended.

Inspection Tips for Surveyors

When inspecting a Scano Type II house, surveyors should pay close attention to the following areas:

1. Substructure and Damp-Proof Course: Check for signs of moisture ingress or structural movement in the concrete strip footings and perimeter basement wall. Ensure the DPC is intact and functioning effectively.

2. External Walls: Inspect the render for cracks or damage that could allow moisture penetration. Examine the timber frame panels for signs of rot or insect infestation.

3. Roof Structure: Assess the condition of the timber rafters, boarding, and battens. Look for any missing or damaged tiles that could compromise the roof’s integrity.

4. Internal Partitions and Floors: Check for signs of movement or damage in the timber stud partitions and T&G boarding. Ensure the plasterboard linings are secure and free from moisture damage.

5. Overall Structural Integrity: Evaluate the overall structural integrity of the house, paying particular attention to any signs of settlement or movement.

Common Defects in Scano Type II Houses

Despite their robust construction, Scano Type II houses can suffer from several common defects. These include:

• Wood Rot and Insect Infestation: Timber components are susceptible to rot and insect damage, particularly if moisture ingress occurs.

• Moisture Ingress: The use of bituminous paper in the wall construction can lead to moisture ingress if not properly maintained.

• Structural Movement: As with many older properties, structural movement can occur over time, leading to cracks and other issues.

• Roofing Issues: Missing or damaged tiles can compromise the roof’s integrity, leading to leaks and other problems.

Maintaining a Scano Type II House

Proper maintenance is crucial to preserving the integrity and value of a Scano Type II house. Regular inspections and timely repairs can help prevent minor issues from becoming major problems. Homeowners should focus on the following areas:

• Moisture Control: Ensure the DPC is functioning effectively and address any signs of moisture ingress promptly.

• Timber Preservation: Regularly inspect timber components for signs of rot or insect damage and treat as necessary.

• Roof Maintenance: Keep the roof in good condition by replacing missing or damaged tiles and addressing any leaks promptly.

• Structural Monitoring: Monitor the property for signs of structural movement and address any issues as soon as they arise.

Investing in a Scano Type II House

For investors, the Scano Type II house represents a unique opportunity to own a piece of architectural history. However, due diligence is essential to ensure a sound investment. Consider the following factors:

• Historical Value: The rarity and historical significance of the Scano Type II house can add value to the property.

• Potential for Renovation: With the right approach, these houses can be renovated to modern standards while preserving their unique character.

• Market Demand: Assess the demand for unique, historical properties in the area to gauge potential resale value.

• Professional Guidance: Engage a professional surveyor with expertise in timber-framed houses to conduct a thorough inspection and provide guidance on any necessary repairs or renovations.
