1. Introduction: Extending Sustainably for a Net Zero Future
Home extensions remain one of the UK’s most popular renovation projects—but sustainability is now essential.
At Synergy Group, we help homeowners design and build energy-efficient, low-carbon extensions that comply with modern building regulations and enhance long-term value.
2. Step 1: Start with Sustainable Design
A good design integrates efficiency from the outset. Consider:
- Orientation – maximise natural light and minimise overheating.
- Fabric-first design – focus on insulation, airtightness, and moisture control.
- Renewable integration – plan roof layouts for solar PV or heat pumps early.
Our design team models each extension under Part L, F, and O to ensure compliance.
3. Step 2: Choose the Right Materials
Sustainable materials reduce embodied carbon and improve durability.
We recommend:
- Timber or steel frames from certified sources
- Recycled insulation (wood fibre, hemp, or mineral wool)
- Low-VOC finishes for indoor air quality
4. Step 3: Ensure Energy & Ventilation Balance
Insulation without ventilation leads to condensation.
We balance your extension’s thermal envelope with efficient mechanical ventilation systems, ensuring comfort and air quality in line with Part F.
5. Step 4: Plan for Compliance and Certification
Synergy manages planning permissions, Building Regulation approvals, and PAS 2035 documentation to keep your project compliant from start to finish.
We handle everything from U-value calculations to as-built energy modelling for EPC certification.
6. Step 5: Build for the Long Term
Our construction partners deliver extensions built to Net Zero-ready standards—integrating renewable systems, high-performance glazing, and smart controls.
The result: lower bills, increased comfort, and enhanced resale value.
