Historical Context and Manufacturing

The Nuttall MK II house, a notable example of post-war British architecture, was manufactured by Nuttall Houses (Richmond) Ltd. Designed by Steane Shipman & Associates and A George & Associates, these properties were constructed in 1964. The Nuttall MK II houses were part of a broader initiative to address the housing shortage in the UK during the post-war period. These homes were built using system-built construction methods, which allowed for rapid assembly and cost-effective production.

Typical Locations and Distribution

Nuttall MK II houses are predominantly found in suburban areas across the UK. They were constructed as part of large housing estates, often in regions that experienced significant population growth during the 1960s. These properties can be found in both urban and rural settings, providing a range of housing options for different demographics.

Identification Characteristics

Nuttall MK II houses are easily identifiable by their distinct architectural features. They are typically two-storey detached, semi-detached, or terraced houses with a medium pitch gable roof covered with interlocking concrete tiles. The front and rear external walls are clad in shiplap timber boarding, while the gable walls are constructed from brick. These characteristics make the Nuttall MK II house a unique and recognizable property type.

Construction Details

Substructure

The substructure of the Nuttall MK II house consists of a concrete slab that is thickened around the perimeter. This design provides a stable foundation for the property and helps to distribute the load evenly across the ground.

Frame

The frame of the Nuttall MK II house is constructed from 19 RS hollow box stanchions, with three single-storey stanchions. The floor support beam is an RSJ, and the floor joists are lattice in design. The frame also includes double RSA mock perimeter beams, RSC perimeter beams, and roof trusses with lattice rafters and RSA ties. The protective coating for the frame is not known, which may be a consideration for potential buyers and investors.

External Walls

The front and rear external walls are constructed from shiplap timber boarding on timber battens, with a cavity and Stramit board on timber battens. The gable walls are made from cavity brick throughout. This combination of materials provides both aesthetic appeal and structural integrity.

Partitions

Internal partitions in the Nuttall MK II house are made from Stramit strawboard. This material is lightweight and provides adequate sound insulation between rooms.

Floors

The ground floor is constructed from concrete, while the first floor consists of plywood on timber battens. This design provides a solid and durable flooring system for the property.

Ceilings

The ceilings in the Nuttall MK II house are made from plasterboard, which is a common material used in residential construction for its ease of installation and finish.

Roof

The roof is constructed from bituminous felt, timber battens, and interlocking concrete tiles. This design provides a weather-resistant and durable roofing system for the property.

Typical Hazards and Risks

Structural Integrity

One of the primary concerns with Nuttall MK II houses is the potential for structural issues. The use of steel frames and timber cladding can lead to problems with corrosion and rot if not properly maintained. It is essential to inspect the condition of the frame and cladding regularly to ensure the structural integrity of the property.

Moisture Ingress

The design of the Nuttall MK II house includes cavities in the external walls, which can be prone to moisture ingress if not properly sealed. This can lead to issues with damp and mould, which can affect the health of the occupants and the overall condition of the property.

Insulation and Energy Efficiency

Nuttall MK II houses were built during a time when energy efficiency was not a primary concern. As a result, these properties may have inadequate insulation, leading to higher energy bills and a less comfortable living environment. Upgrading the insulation in the walls, roof, and floors can significantly improve the energy efficiency of the property.

Asbestos

As with many properties built during the 1960s, there is a possibility that asbestos-containing materials were used in the construction of Nuttall MK II houses. It is essential to have a thorough asbestos survey conducted before any renovation or demolition work is carried out to ensure the safety of the occupants and workers.

Defective Premises Act

The Nuttall MK II house is not specifically classed as defective under the Defective Premises Act. However, it is essential to be aware of the potential issues and risks associated with this property type. Regular inspections and maintenance can help to mitigate these risks and ensure the property remains in good condition.

Inspection and Assessment Guide

External Inspection

When inspecting a Nuttall MK II house, start with the external elements. Check the condition of the shiplap timber boarding on the front and rear walls. Look for signs of rot, warping, or damage. Inspect the brick gable walls for any cracks or signs of movement. Examine the roof for missing or damaged tiles and check the condition of the bituminous felt and timber battens.

Internal Inspection

Inside the property, inspect the condition of the Stramit strawboard partitions. Look for any signs of damage or deterioration. Check the condition of the plasterboard ceilings and ensure there are no signs of water damage or sagging. Inspect the floors for any signs of movement or damage, particularly in the plywood on timber battens on the first floor.

Frame Inspection

The steel frame is a critical component of the Nuttall MK II house. Inspect the RS hollow box stanchions, RSJ floor support beam, lattice floor joists, and roof trusses for any signs of corrosion or damage. If the protective coating is not known, consider having a professional assessment conducted to determine the condition of the frame.

Moisture and Insulation

Check for any signs of moisture ingress in the external walls, particularly in the cavities. Look for signs of damp or mould, which can indicate issues with the sealing or insulation. Assess the insulation in the walls, roof, and floors and consider upgrading if necessary to improve the energy efficiency of the property.

Asbestos Survey

Given the age of the Nuttall MK II house, it is essential to conduct an asbestos survey before any renovation or demolition work. Asbestos-containing materials may be present in the property, and it is crucial to identify and manage these materials safely.

Typical Defects and Maintenance

Timber Cladding

The shiplap timber boarding on the front and rear walls can be prone to rot and warping if not properly maintained. Regularly inspect the condition of the timber and treat it with a suitable preservative to protect against moisture and insect damage.

Steel Frame

The steel frame is susceptible to corrosion, particularly if the protective coating is not known or has deteriorated. Regular inspections and maintenance are essential to ensure the frame remains in good condition. Consider having a professional assessment conducted to determine the condition of the frame and any necessary repairs or treatments.

Roof

The bituminous felt and interlocking concrete tiles on the roof can be prone to damage from weathering and age. Regularly inspect the condition of the roof and replace any damaged or missing tiles. Ensure the bituminous felt is in good condition and repair any areas that show signs of wear or damage.

Insulation

Upgrading the insulation in the walls, roof, and floors can significantly improve the energy efficiency of the Nuttall MK II house. Consider installing modern insulation materials to reduce heat loss and improve the comfort of the property.

Moisture Management

Proper moisture management is essential to prevent issues with damp and mould. Ensure the cavities in the external walls are properly sealed and check for any signs of moisture ingress. Install adequate ventilation in the property to reduce humidity levels and prevent condensation.

Conclusion

The Nuttall MK II house is a unique and recognizable property type with distinct architectural features and construction methods. While these properties offer a range of benefits, including rapid assembly and cost-effective production, they also come with potential risks and hazards. Regular inspections and maintenance are essential to ensure the structural integrity and overall condition of the property.

When considering the purchase of a Nuttall MK II house, it is crucial to be aware of the typical defects and maintenance requirements associated with this property type. By conducting thorough inspections and addressing any issues promptly, you can ensure the longevity and comfort of your home.
