Sustainable construction isn’t about compromise, it’s about building smarter. At Build Nine, we focus on materials and methods that support energy efficiency, durability, and health, all while delivering elegant, design-led spaces.
Insulation is a key component. Traditional fibreglass or foam often isn’t suitable for heritage homes. We opt for natural insulation like Steico wood-fibre, which is breathable and effective, especially when paired with lime plaster and natural paints. This system maintains airflow, prevents condensation, and contributes to a healthier indoor environment.
We also prioritise responsible sourcing. Timber is FSC-certified, stone is often locally reclaimed, and finishes like Edward Bulmer paints are chosen for their environmental credentials. These choices not only reduce carbon impact but also align with the aesthetic of older homes.
Energy performance is enhanced through thoughtful systems. We regularly install underfloor heating, high-performance glazing, and smart controls that optimise comfort while cutting energy use. Airtightness, often overlooked, is improved through careful detailing, especially in roof and wall junctions.
But sustainability isn’t just about materials, it’s about lifespan. Our work is built to last, reducing the need for frequent renovations. When we design and build, we consider future adaptability, reducing waste over time.
For clients across the South East, a sustainable home is now a realistic and elegant option. With Build Nine, it’s possible to honour the past and build for the future, beautifully.
