Understanding the Elementhus House

The Elementhus house, a distinctive type of system-built property, emerged in the UK during the 1960s. Designed by Lennart Bergvall and manufactured by AB Bostadsforskning, these homes are a testament to the innovative architectural approaches of their time. As a prospective homebuyer or investor, understanding the unique characteristics and potential challenges of Elementhus houses is crucial. This guide will delve into the construction, typical features, and considerations for purchasing such a property.

Historical Context and Manufacturing

Elementhus houses were primarily constructed in the 1960s, a period marked by a housing boom and a demand for quick, efficient building methods. AB Bostadsforskning, a Swedish company, spearheaded the production of these homes, leveraging prefabrication techniques to meet the growing need for affordable housing. The design by Lennart Bergvall focused on creating functional, durable homes that could be assembled rapidly on-site.

Typical Locations and Numbers Built

While exact numbers are elusive, Elementhus houses were predominantly built in suburban areas across the UK. These homes were part of a broader movement towards system-built housing, which sought to address post-war housing shortages. Their presence is more common in regions that experienced significant urban expansion during the 1960s.

Architectural Characteristics

Elementhus houses are typically detached bungalows, identifiable by their unique construction features. They often feature steep, medium, or shallow pitch gable or flat roofs, covered with bituminous felt or metal sheets. The front and rear external walls are composed of vertical storey-height prefabricated slabs, faced with stove-enamelled aluminium sheets. Gable walls are clad with vertical timber boarding, adding to their distinctive appearance.

Construction Details

The construction of Elementhus houses is a fascinating blend of prefabrication and traditional building methods. Here’s a detailed look at their construction:

• Substructure: These homes rest on narrow concrete strip foundations, providing a stable base. A damp-proof course (DPC) is typically included to prevent moisture ingress.

• External Walls: The walls are constructed from 200 mm x 200 mm storey-height prefabricated hollow box section timber panels. These panels are packed with sawdust and compressed wood shavings, set on horizontal box section prefabricated beams and metal sills. Externally, they are sheathed with stove-enamelled aluminium sheets.

• Gable Walls: Directly clad with timber boarding, these walls contribute to the house’s aesthetic and structural integrity.

• Partitions: Internal partitions are made from 100 mm x 100 mm prefabricated hollow box section timber panels, also packed with sawdust and compressed wood shavings.

• Ground Floor: Similar to the walls, the ground floor consists of prefabricated hollow box section timber panels.

• Ceilings and Roof: The ceilings are constructed from timber soffit panels, while the roof is supported by timber trusses carried on box section ceiling units. The roof covering can vary, offering flexibility in design.

Potential Hazards and Risks

While Elementhus houses offer unique architectural appeal, they also come with potential hazards and risks that buyers should be aware of:

• Moisture Ingress: The use of sawdust and compressed wood shavings in the construction can lead to moisture retention, potentially causing rot or mould if not properly managed.

• Thermal Insulation: The original design may not meet modern insulation standards, leading to higher energy costs. Retrofitting with modern insulation materials can mitigate this issue.

• Structural Integrity: Over time, the prefabricated panels may experience wear and tear, affecting the structural integrity of the home. Regular inspections are essential to identify and address any issues early.

Defective Premises Act Considerations

Elementhus houses are not specifically classified as defective under the Defective Premises Act. However, due diligence is necessary when purchasing any older property. Engaging a professional surveyor to conduct a thorough inspection can help identify any potential defects or areas of concern.

Inspection Tips for Surveyors

When inspecting an Elementhus house, surveyors should focus on several key areas:

• Foundation and Substructure: Check for signs of subsidence or movement in the narrow concrete strip foundations. Ensure the damp-proof course is intact and effective.

• External and Internal Walls: Inspect the prefabricated panels for signs of moisture damage, rot, or structural weakness. Pay particular attention to the condition of the aluminium sheathing and timber boarding.

• Roof and Ceilings: Examine the roof trusses and covering for signs of wear, leaks, or damage. Ensure the timber soffit panels are in good condition.

• Thermal Performance: Assess the insulation levels and identify opportunities for improvement to enhance energy efficiency.

Variants and Adaptations

Elementhus houses come in several variants, primarily distinguished by the roof design. Buyers may encounter homes with steep, medium, or flat roofs, each offering different aesthetic and functional benefits. Understanding these variants can help buyers make informed decisions based on their preferences and needs.

Modern Considerations for Elementhus Houses

In 2024, the housing market is increasingly focused on sustainability and energy efficiency. Elementhus houses, with their unique construction, present both challenges and opportunities in this regard. Retrofitting these homes with modern insulation, energy-efficient windows, and renewable energy systems can significantly enhance their performance and reduce environmental impact.

Sustainability and Energy Efficiency

Improving the sustainability of an Elementhus house involves several key steps:

• Insulation Upgrades: Retrofitting with modern insulation materials can improve thermal performance and reduce energy costs. Consider using eco-friendly insulation options to align with sustainability goals.

• Window and Door Replacements: Upgrading to double or triple-glazed windows and energy-efficient doors can enhance thermal efficiency and reduce heat loss.

• Renewable Energy Systems: Installing solar panels or heat pumps can further reduce the home’s carbon footprint and provide long-term energy savings.

Legal and Financial Considerations

When purchasing an Elementhus house, buyers should be aware of potential legal and financial considerations:

• Mortgage Availability: Some lenders may be cautious about providing mortgages for system-built homes due to perceived risks. It’s essential to work with a mortgage broker experienced in dealing with non-standard construction properties.

• Insurance: Securing insurance for an Elementhus house may require specialist providers familiar with the unique construction methods. Ensure comprehensive coverage that addresses potential risks.

• Renovation and Maintenance Costs: Factor in potential renovation and maintenance costs when budgeting for an Elementhus house. Regular upkeep is crucial to maintaining the property’s value and structural integrity.

Community and Lifestyle Benefits

Despite the challenges, Elementhus houses offer several lifestyle benefits that appeal to modern buyers:

• Unique Design: The distinctive architectural style of Elementhus houses sets them apart from conventional homes, offering a unique living experience.

• Spacious Layouts: As detached bungalows, these homes often provide generous living spaces, ideal for families or those seeking a more open living environment.

• Community Appeal: Many Elementhus houses are located in established communities with access to amenities, schools, and transport links, enhancing their appeal to families and professionals alike.

Future Prospects and Market Trends

As the UK housing market evolves, Elementhus houses continue to hold potential for buyers and investors. Their unique design and historical significance make them attractive to niche markets, while modernisation efforts can enhance their value and appeal.

Investment Potential

For investors, Elementhus houses offer several opportunities:
