Historical Context and Manufacturing Details

The Herald house, also known as the Page-Johnson house, was manufactured by Page-Johnson Construction Ltd and designed by Page-Johnson Design Ltd. These properties were predominantly built during the 1960s, a period marked by a significant demand for affordable housing solutions in the UK. The exact number of Herald houses built remains unclear, but they were a common sight in various parts of the country, particularly in suburban areas.

Typical Locations

Herald houses are typically found in suburban neighbourhoods, often forming part of larger housing estates. These properties were designed to cater to the growing middle-class population, offering a blend of affordability and modernity. They are commonly seen in areas that experienced rapid urban development during the 1960s, such as the outskirts of major cities and towns.

Manufacturers and Designers

The manufacturers, Page-Johnson Construction Ltd, were known for their innovative approach to housing construction. They collaborated closely with Page-Johnson Design Ltd, the designers behind the Herald house. This partnership aimed to create a property that was not only cost-effective but also aesthetically pleasing and functional for the average family.

Characteristics of the Herald House

Understanding the typical characteristics of the Herald house is essential for potential buyers and investors. These properties come with distinct features that set them apart from other housing types.

Architectural Design

Herald houses are available in two main configurations: bungalows and two-storey terraced houses. Both types share several common architectural elements, including:

• Shallow Pitch Hipped Roof: The roof is covered with interlocking concrete tiles, providing durability and a distinctive appearance.
• External Walls: The front and rear external walls are clad with vertical timber boarding up to the first-floor level, with shiplap timber boarding or tile hanging above. This design choice adds a rustic charm to the property.
• Flank Walls: The flank walls are typically finished with textured concrete, with exposed ends or faced with light-coloured stone bricks.

Construction Details

The construction of Herald houses involves several key components, each contributing to the overall stability and functionality of the property.

Substructure

• Concrete Ring Beam: This forms the foundation of the property, providing structural support.
• Concrete Slab: The ground floor is constructed using a concrete slab, ensuring a solid base.
• Damp Proof Membrane (DPM): A DPM is incorporated to prevent moisture ingress, protecting the property from damp-related issues.

External Walls

• Timber Frame Panels: The front and rear walls are constructed using timber frame panels, directly clad with vertical timber boarding backed with bituminous felt up to the first-floor level.
• Shiplap Boarding: Above the first-floor level, shiplap boarding is used, adding an extra layer of protection and aesthetic appeal.
• Foil-Backed Plasterboard: The internal lining of the walls consists of foil-backed plasterboard, enhancing insulation and fire resistance.

Flank Walls

• Lightweight Aggregate Concrete: The flank walls are constructed using 8-inch lightweight aggregate concrete, providing strength and durability.

Separating Walls

• Dense Aggregate Concrete: The separating walls between properties are made of 8-inch dense aggregate concrete, ensuring sound insulation and fire resistance.

Partitions

• Timber Stud Partitions: Internal partitions are constructed using timber studs lined with plasterboard, offering flexibility in interior design.

Floors

• Ground Floor: The ground floor is made of concrete, providing a solid and stable base.
• First Floor: The first floor consists of chipboard on timber joists, supported by 2-inch by 1/4-inch mild steel straps and a timber wall plate.

Roof

• Timber Rafters and Binders: The roof structure is made of timber rafters and binders, covered with interlocking concrete tiles, ensuring weather resistance and longevity.

Typical Hazards and Risks

While Herald houses offer several advantages, they also come with potential hazards and risks that buyers and investors should be aware of.

Structural Issues

One of the primary concerns with Herald houses is the potential for structural issues, particularly related to the timber frame and concrete components. Over time, timber can be susceptible to rot and insect infestation, while concrete may suffer from cracking and spalling.

Damp and Moisture

Despite the inclusion of a damp proof membrane, Herald houses can still be prone to damp and moisture issues, especially if the DPM is damaged or improperly installed. Moisture ingress can lead to mould growth, wood rot, and other related problems.

Insulation and Energy Efficiency

The insulation in Herald houses, particularly in the external walls, may not meet modern standards. This can result in higher energy bills and reduced comfort levels. Upgrading the insulation can be a worthwhile investment to improve energy efficiency.

Fire Safety

While the use of foil-backed plasterboard enhances fire resistance, it is essential to ensure that all fire safety measures are up to date. This includes checking the condition of fire doors, smoke alarms, and other fire safety equipment.

Defective Premises Act and Classification

The Defective Premises Act 1972 is a crucial piece of legislation that aims to protect homeowners from defects in their properties. Under this act, a property is considered defective if it fails to meet the required standards of safety and habitability.

Classification of Herald Houses

Herald houses are not universally classified as defective under the Defective Premises Act. However, due to their age and construction methods, they may be more susceptible to certain defects. It is essential to conduct a thorough inspection to identify any potential issues and address them promptly.

Inspection Tips for Herald Houses

Conducting a detailed inspection is vital when considering the purchase of a Herald house. Here are some key areas to focus on during the inspection process:

External Walls

• Check for Rot and Insect Damage: Inspect the timber cladding for signs of rot or insect infestation. Pay particular attention to areas where the timber meets the ground or is exposed to moisture.
• Examine the Concrete: Look for cracks, spalling, or other signs of deterioration in the concrete components. These issues can compromise the structural integrity of the property.

Roof

• Inspect the Tiles: Check the condition of the interlocking concrete tiles on the roof. Look for any missing, cracked, or damaged tiles that may need replacement.
• Assess the Timber Rafters: Examine the timber rafters and binders for signs of rot, warping, or other damage. Ensure that the roof structure is sound and secure.

Floors

• Check for Moisture: Inspect the ground floor for signs of moisture ingress, such as damp patches or mould growth. Ensure that the damp proof membrane is intact and functioning correctly.
• Examine the First Floor: Look for any signs of sagging or unevenness in the first-floor chipboard and timber joists. This could indicate structural issues that need addressing.

Insulation and Energy Efficiency

• Assess the Insulation: Check the insulation in the external walls and roof space. Consider upgrading the insulation if it does not meet modern standards.
• Evaluate Energy Efficiency: Look for opportunities to improve energy efficiency, such as installing double-glazed windows or upgrading the heating system.

Fire Safety

• Check Fire Safety Measures: Ensure that all fire safety measures are in place and up to date. This includes checking the condition of fire doors, smoke alarms, and other fire safety equipment.

Typical Defects in Herald Houses

Understanding the common defects in Herald houses can help you identify potential issues and take appropriate action.

Timber Frame Issues

• Rot and Insect Infestation: Timber components, particularly those exposed to moisture, can be susceptible to rot and insect infestation. Regular inspections and maintenance are essential to prevent these issues.
• Warping and Splitting: Timber can warp or split over time, especially if it is not adequately protected from the elements. This can compromise the structural integrity of the property.

Concrete Deterioration

• Cracking and Spalling: Concrete components, such as the ring beam and slab, can develop cracks and spalling over time. These issues can weaken the structure and require prompt repair.
• Carbonation: Carbonation is a chemical reaction that occurs in concrete, leading to the corrosion of embedded steel reinforcement. This can compromise the strength and durability of the concrete.

Damp and Moisture Issues

• Damp Proof Membrane Failure: If the damp proof membrane is damaged or improperly installed, moisture can penetrate the property, leading to damp and mould issues.
• Condensation: Poor insulation and ventilation can result in condensation, particularly in colder months. This can lead to mould growth and other related problems.

• Inadequate Insulation: The insulation in Herald houses may not meet modern standards, resulting in higher energy bills and reduced comfort levels. Upgrading the insulation can improve energy efficiency and reduce heating costs.
• Single-Glazed Windows: Many Herald houses still have single-glazed windows, which are less energy-efficient than double-glazed alternatives. Replacing single-glazed windows with double glazing can enhance energy efficiency and reduce heat loss.

Variants of the Herald House

While the standard design of the Herald house is well-documented, there are several variants that potential buyers and investors should be aware of.

Upper Storey Cladding

In some variants of the Herald house, the upper storey of the front and rear external walls is clad with tile hanging instead of shiplap boarding. This design choice can affect the property’s appearance and maintenance requirements.

Flats

The Herald house system was also used for flats, offering a similar construction and design approach. When inspecting these properties, it is essential to consider the same potential hazards and risks as with the standard Herald house.
