The Sunskeeme house is typically a two-storey terraced house, easily identifiable by its distinct architectural features. Here are some key characteristics to help you recognize a Sunskeeme house:

• Roof: The house features a shallow pitch gable roof covered with tiles.
• External Walls: The front and rear walls are clad with asbestos cement panels up to the ground floor window sill level. Above this, the walls are covered with horizontal timber boarding, aluminium sheets, or tile hanging. The gable wall is constructed of brick throughout or up to the first floor level, with tile hanging above.
• Canopy: A flat canopy over the front door, accompanied by slatted timber side panels, is a common feature.

These characteristics make the Sunskeeme house stand out among other property types, providing a unique aesthetic appeal.

Construction Details

Understanding the construction details of the Sunskeeme house is essential for assessing its structural integrity and potential risks. Here is a breakdown of the typical construction elements:

Substructure

The substructure of the Sunskeeme house consists of concrete strip footings and a concrete slab. A damp-proof course (DPC) is also incorporated to prevent moisture ingress.

External Walls

The front and rear walls are constructed using storey-height timber frame panels directly clad with asbestos cement panels up to the ground floor window sill level. Above this, the walls are covered with horizontal timber boarding. The gable wall is made of brick, with a cavity and reinforced concrete (RC) elements.

Separating Wall

The separating wall between terraced houses is constructed using reinforced concrete (RC), providing structural stability and sound insulation.

Partitions

The ground floor partitions are not well-documented, but the first-floor partitions are made of concrete, ensuring durability and fire resistance.

Floors

The ground floor is constructed using concrete, while the first floor features an RC slab cast monolithically with the gable and cross walls to form H-frames. This construction method enhances the overall structural integrity of the house.

Ceilings

The ceilings are made of concrete slabs, providing additional strength and fire resistance.

Roof

The roof is prefabricated and sectional, covered with tiles. This design allows for quick assembly and provides adequate weather protection.

Typical Variants

While the basic design of the Sunskeeme house remains consistent, there are some variants in the external cladding of the upper storey walls. These include:

• Tile Hanging: Some Sunskeeme houses feature tile hanging on the upper storey external walls.
• Aluminium Sheets: In other variants, the upper storey external walls are clad with aluminium sheets.

These variations do not significantly impact the overall structure but may influence the aesthetic appeal and maintenance requirements.

Typical Hazards and Risks

As with any property type, the Sunskeeme house has its share of potential hazards and risks. Being aware of these issues can help you make an informed decision when considering a purchase.

Asbestos Cement Panels

One of the primary concerns with Sunskeeme houses is the presence of asbestos cement panels on the external walls. Asbestos was commonly used in construction during the 1960s and 1970s due to its fire-resistant properties. However, it is now known to pose significant health risks if disturbed. When inspecting a Sunskeeme house, it is crucial to check the condition of the asbestos cement panels and ensure they are not damaged or deteriorating.

Reinforced Concrete Durability

The durability of reinforced concrete (RC) elements is another critical factor to consider. Over time, RC can be susceptible to corrosion, especially if exposed to moisture. The following resources provide valuable guidance on inspecting and assessing the durability of reinforced concrete:

• Corrosion of Steel in Concrete (BRE Digest 444, Pts 1–3)
• Repair and Maintenance of Reinforced Concrete (BR 254)
• Carbonation Depths in Structural-Quality Concrete (BR 19)

These resources offer insights into identifying and addressing potential issues with reinforced concrete, ensuring the long-term stability of the property.

Moisture Ingress

Moisture ingress can lead to various problems, including mould growth, structural damage, and deterioration of building materials. The presence of a damp-proof course (DPC) in the substructure helps mitigate this risk. However, it is essential to inspect the DPC and ensure it is functioning correctly.

Structural Integrity

The overall structural integrity of the Sunskeeme house is generally robust, thanks to the use of reinforced concrete and prefabricated components. However, it is essential to inspect the property for any signs of structural damage, such as cracks in the walls or floors. These issues could indicate underlying problems that require further investigation.

Defective Premises Act

The Defective Premises Act 1972 imposes a duty on builders, developers, and landlords to ensure that properties are constructed and maintained to a reasonable standard. While the Sunskeeme house is not specifically classed as defective under this act, it is essential to be aware of any potential issues that could impact the property’s safety and habitability.

Inspection Tips for Surveyors

When inspecting a Sunskeeme house, it is crucial to follow a systematic approach to identify any potential issues. Here are some useful tips for surveyors:

External Inspection

• Roof: Check the condition of the roof tiles and ensure there are no missing or damaged tiles. Inspect the shallow pitch gable roof for any signs of sagging or structural issues.
• Walls: Examine the asbestos cement panels for any signs of damage or deterioration. Check the horizontal timber boarding, aluminium sheets, or tile hanging for any signs of wear and tear.
• Canopy: Inspect the flat canopy over the front door and the slatted timber side panels for any signs of damage or decay.

Internal Inspection

• Floors: Check the condition of the concrete ground floor and the RC slab on the first floor. Look for any signs of cracks or structural damage.
• Walls: Inspect the internal walls for any signs of moisture ingress, cracks, or structural issues. Pay particular attention to the reinforced concrete separating wall.
• Ceilings: Examine the concrete slab ceilings for any signs of damage or deterioration.

Moisture and Dampness

• DPC: Ensure the damp-proof course (DPC) is functioning correctly and there are no signs of moisture ingress.
• Mould: Look for any signs of mould growth, which could indicate moisture issues.

Structural Integrity

• Cracks: Check for any cracks in the walls, floors, or ceilings, which could indicate structural problems.
• Corrosion: Inspect the reinforced concrete elements for any signs of corrosion or deterioration.
