High Bar Lane: Building the Next Generation of Climate-Positive Home
Across the UK, the demand for sustainable, energy-efficient housing has never been greater. Homebuyers are increasingly looking for homes that not only reduce their environmental impact but also offer long-term protection from rising energy costs.
At High Bar Lane, Thakeham, EARTHSTONE HOMES® and HEMSPAN® will demonstrate exactly what the future of housing can look like.
This exciting new development will deliver 28 climate-positive homes using HEMSPAN®’s innovative BIOHAUS® construction system, combining timeless British architecture with exceptional building performance, ultra-low embodied carbon and the potential for zero energy bills.
Traditional Homes. Revolutionary Performance.
From the outside, High Bar Lane feels perfectly at home within the Sussex landscape.
The homes reflect the character of traditional village architecture, sitting comfortably within the established community of Thakeham while benefiting from cutting-edge construction technology hidden beneath the surface.
This is the philosophy behind EARTHSTONE HOMES®
Beautiful homes shouldn’t require compromise. Nor should sustainability.
Instead, High Bar Lane proves that buyers can enjoy classic design alongside some of the highest-performing homes being built in Britain today.
Designed Around the Fabric First Principle
Rather than relying solely on technology to reduce energy use, High Bar Lane starts with the building itself.
Every home is constructed using the BIOHAUS® closed-panel system, creating an exceptionally well-insulated building envelope that dramatically reduces heat loss.
Key performance features include:
- Overall U-values of approximately 0.100 W/m²K
- Passive House-level thermal performance
- Breathable wall construction
- Ultra-low embodied carbon
- Around 1 tonne of CO₂ stored per square metre compared with conventional construction
- Faster off-site manufactured construction using Category 2 Modern Methods of Construction (MMC).
The result is a home that stays warmer in winter, cooler in summer and requires significantly less energy to operate.
Zero Bills by Design
Perhaps the most exciting aspect of High Bar Lane is its ambition to create homes with the potential for zero energy bills.
Each home has been designed to integrate renewable technologies and intelligent energy management from the outset.
This includes:
- Solar photovoltaic panels
- Battery storage
- Air source heat pumps
- Mechanical Ventilation with Heat Recovery (MVHR)
Working together, these technologies can dramatically reduce household energy demand while improving comfort throughout the year.
For homeowners, that means lower running costs, greater resilience against energy price fluctuations and a healthier indoor environment.
A Better Way to Build Communities
High Bar Lane is more than a housing development.
It demonstrates how sustainable communities can be delivered without sacrificing quality, affordability or place-making.
The development includes 28 homes, with 10 designated as affordable housing, helping meet local housing needs while maintaining the same commitment to high-performance, climate-conscious construction.
Located in the sought-after village of Thakeham, residents will benefit from:
- Excellent commuter links to London, Gatwick and the South Coast
- Access to the South Downs National Park
- A thriving village community
- Green open spaces and countryside
- Highly desirable family living.
Leading the Future of Low-Carbon Housing
The UK faces a significant challenge. We need to build more homes while dramatically reducing carbon emissions.
High Bar Lane demonstrates that these two ambitions can go hand in hand.
By combining bio-based materials, off-site manufacturing, intelligent energy systems and thoughtful design, EARTHSTONE HOMES® and HEMSPAN® are helping redefine what buyers should expect from a modern home.
Climate-positive construction is no longer an aspiration, it’s becoming reality.
