Historical Context and Manufacturer Background

The Northern Ideal Homesteads house, a product of Northern Ideal Homesteads Ltd under the Land & Developments Group, represents a significant chapter in the history of British housing. These properties were constructed in 1966, a period marked by a surge in the demand for affordable and quickly built homes. The design and construction of these houses were driven by the need to address the post-war housing shortage, leveraging industrialised building techniques to expedite the process.

Northern Ideal Homesteads Ltd, known for its innovative approach, collaborated with designers to create homes that were not only quick to build but also aimed to provide a comfortable living environment. The houses were also known by alternative names such as Bracpress, Ideal, and Ideal Industrialised, reflecting their industrialised construction methods.

Identification Characteristics

The Northern Ideal Homesteads houses can be identified by several distinct features. These properties are typically bungalows or two-storey semi-detached and terraced houses. They feature a medium pitch gable roof covered with interlocking concrete tiles, which is a common characteristic of homes from this era.

The front and rear walls of these houses are constructed from timber frame panels, complete with door and window units on the ground floor. The first floor level features aggregate-faced glass reinforced plastics spandrel panels, with timber frame panels and windows above. The gable walls are entirely made of aggregate-faced glass fibre reinforced plastics panels, providing a unique aesthetic and structural characteristic.

A notable feature is the timber frame flat canopy on tubular supports over the front door, adding to the distinctive look of these homes. The separating walls between properties are covered with aggregate-faced glass reinforced plastics panels, ensuring a degree of uniformity and structural integrity.

Construction Details

Substructure

The substructure of Northern Ideal Homesteads houses includes reinforced concrete (RC) edge beams and a concrete slab, providing a solid foundation. A concrete plinth and damp-proof course (DPC) are also integral parts of the substructure, ensuring protection against moisture ingress.

Frame

The main frame consists of 20 RS lattice stanchions, with some single-storey variations. The perimeter beams are made of 4 RSJ (Rolled Steel Joist), and there is one RSJ floor support beam along with 8 RS lattice trusses. The entire frame is galvanised, offering protection against corrosion and enhancing the longevity of the structure.

External Walls

The external walls are a combination of timber frame panels and aggregate-faced glass fibre reinforced plastics panels. The front and rear walls feature timber frame panels with door and window units on the ground floor, and aggregate-faced glass fibre plastics spandrel panels at the first floor level. The gable walls are entirely made of aggregate-faced glass fibre reinforced plastics panels, providing a distinctive look and structural integrity.

Separating Wall

The separating wall between properties is a block cavity wall lined with plasterboard. This construction method ensures sound insulation and fire resistance, contributing to the overall safety and comfort of the living environment.

Partitions

Internal partitions are made of Stramit (strawboard) panels, a material known for its insulating properties and ease of installation. These panels are backed with bituminous paper, providing additional moisture resistance.

Floors

The ground floor consists of tongue and groove (T&G) boarding on timber joists, while the first floor features T&G boarding on steel lattice joists. This combination of materials ensures a sturdy and durable flooring system.

Ceilings

Ceilings are constructed from plasterboard, a common material that provides a smooth finish and can be easily decorated to suit individual tastes.

Roof

The roof structure includes counter battens, bituminous felt, and interlocking concrete tiles. This combination provides a robust and weather-resistant roofing system, ensuring the longevity of the property.

Typical Hazards and Risks

While Northern Ideal Homesteads houses were innovative for their time, they do come with certain hazards and risks that potential buyers and investors should be aware of.

Structural Issues

The use of timber frame panels and aggregate-faced glass fibre reinforced plastics panels can lead to structural issues over time. Timber, if not properly treated and maintained, can be susceptible to rot and insect infestation. The glass fibre reinforced plastics panels, while durable, can become brittle and prone to cracking with age.

Moisture Ingress

The concrete slab and plinth, while providing a solid foundation, can be prone to moisture ingress if the damp-proof course (DPC) is compromised. This can lead to damp issues within the property, which can be detrimental to both the structure and the health of the occupants.

Insulation and Energy Efficiency

The construction materials used in Northern Ideal Homesteads houses, such as Stramit panels and bituminous paper, may not meet modern insulation and energy efficiency standards. This can result in higher energy bills and a less comfortable living environment.

Fire Safety

While the separating walls provide a degree of fire resistance, the use of timber and Stramit panels in the construction can pose a fire risk. It is essential to ensure that fire safety measures, such as smoke alarms and fire doors, are in place and regularly maintained.

Defective Premises Act

The Northern Ideal Homesteads houses are not classed as defective under the Defective Premises Act. However, it is crucial for potential buyers and investors to be aware of the typical defects and risks associated with these properties. Regular inspections and maintenance are essential to ensure the safety and longevity of the property.
