Forest Road, E17 – Sustainable New Build with Balcony | IBEX BUILDERS®
A high-performance residential new build featuring Pavaflex wood fibre insulation, MVHR ventilation and a long-life zinc roof.










At IBEX BUILDERS®, we deliver high-quality new build projects that combine modern construction methods with long-term performance, sustainability and attention to detail. Our recent project on Forest Road, E17, demonstrates how careful design and material selection can create a durable, energy-efficient and comfortable home.
This project involved the construction of a new residential flat with a private balcony, built above an existing property, alongside a comprehensive renovation of the building below. From planning through to completion, the focus was on improving building performance, internal comfort and long-term value.
A Modern New Build Designed for Performance
The newly constructed flat was designed to meet the demands of contemporary living, with particular emphasis on thermal efficiency, ventilation and build quality. The inclusion of a private balcony enhances the living space by providing valuable outdoor amenity while strengthening the connection between internal and external areas.
High levels of insulation, airtight construction and modern mechanical systems were integrated throughout the build to ensure consistent comfort and efficient performance in everyday use.
Pavaflex Wood Fibre Insulation – Performance, Comfort and Wellbeing
A key feature of this new build is the use of Pavaflex wood fibre insulation, a high-performance natural insulation system chosen for both its technical advantages and its positive impact on occupant comfort and wellbeing.
Manufactured from natural wood fibres sourced from sustainable forestry, Pavaflex offers an environmentally responsible alternative to conventional synthetic insulation materials while delivering excellent real-world performance.
Its thermal resistance and high thermal mass help stabilise internal temperatures, reducing heat loss during colder months and limiting overheating in warmer conditions.
This improves energy efficiency and reduces reliance on mechanical heating and cooling.
Pavaflex is vapour-open, allowing the building fabric to breathe and helping regulate moisture levels within the structure.
This significantly reduces the risk of condensation, mould growth and damp-related issues, protecting both the building fabric and indoor air quality.
By supporting a balanced internal environment, wood fibre insulation contributes to healthier living conditions, particularly in modern airtight homes where comfort and wellbeing are closely linked to humidity control and air quality.
Mechanical Ventilation with Heat Recovery (MVHR)
To complement the airtight and insulated building envelope, the flat was fitted with a Mechanical Ventilation with Heat Recovery (MVHR) system. This system continuously supplies fresh air while extracting stale air, recovering heat in the process.
The MVHR system improves indoor air quality, reduces heat loss and ensures a consistent internal climate throughout the year, supporting both comfort and energy efficiency.
Interior Design and Structural Detailing
Internally, the flat features exposed structural rafters, adding character while highlighting the quality and craftsmanship of the build. Clean lines and modern detailing were used throughout to create a bright, functional and contemporary living space.
The layout was carefully designed to maximise natural light and create a strong connection between the interior and the balcony, enhancing the overall sense of space.
Full Renovation of the Existing Property
In addition to the new build above, the existing property below underwent a complete renovation. Works included upgrades to plumbing and electrical systems, along with the installation of new gas and electric meters.
These improvements enhanced the safety, efficiency and reliability of the building as a whole, ensuring that both the new and existing elements perform cohesively.
Zinc Roof – Durable, Low Maintenance and Long-Lasting
The new flat is finished with a zinc roof, selected for its durability, longevity and architectural quality. When correctly detailed and installed, zinc roofing can last 60 to 80 years or more, making it one of the longest-lasting roofing materials available for residential buildings.
Zinc is highly resistant to corrosion, UV exposure and harsh weather conditions, making it particularly well suited to the UK climate. Over time, it forms a natural protective patina that shields the surface from environmental wear and allows minor scratches to self-heal, further extending its service life.
Compared with many traditional roofing systems, zinc requires very little maintenance. It does not crack, warp or degrade in the same way as tiles or bituminous products, helping to reduce long-term maintenance and repair costs.
Zinc is also relatively lightweight, which is beneficial when building above existing structures, as it reduces structural load while maintaining excellent strength and performance. Fully recyclable and extremely durable, it also supports the sustainability objectives of the project and the long-term value of the property.
A Future-Focused New Build
This Forest Road project highlights how thoughtful design, sustainable materials and careful construction can deliver a high-performing residential new build. From insulation and ventilation to the balcony, structure and long-life zinc roofing, every element was chosen with long-term performance, comfort and durability in mind.
At IBEX BUILDERS®, we apply this same level of care and expertise to every new build project we undertake.
