Greencore homes combine contemporary design with exceptional sustainability. Designed to align with Passivhaus standards, each home is naturally comfortable and remarkably efficient, with rooftop solar generating enough clean energy over the year to match what our homes use – delivering Net Zero in operation.

We also cut carbon in construction by using natural materials that quietly store carbon.

By measuring and reducing the carbon impact of every home we build, we go beyond conventional housebuilding creating future-ready homes that are better for people and the planet.

Overall B Impact Score

In 2025, Greencore Homes Ltd became one of the first housebuilders to be B Corp certified. Based on the B Impact assessment, we earned an overall score of 114.5. The median score for ordinary businesses who complete the assessment is currently 50.9.

  1. Roof-Mounted Solar PV We target 100% of energy from renewables
  2. Air Tightness Homes are built to be very airtight reducing heat loss
  3. Well-Insulated Building Envelope Low U-Values for floors, roof and walls, External biond wall panel, Triple-glazed windows
  4. Mechanical Ventilation & Heat Recovery Homes are ventilated and the air is filtered. Heat is recovered from the expelled air
  5. Air Source Heat Pump and/or Electric Heating Efficient, low-carbon heating solution using no fossil fuels
  6. Post Occupancy Evaluation Sensors installed to evauate energy in use
  7. Optimised Orientation & Window Proportions Balance between energy efficiency, overheating and daylight
  8. Optimised Building Form Simplified building shape to reduce heat loss areas and complex junctions

Our Biond Panel System

Our Biond panel is an innovative closed timber frame panel insulated with hemp, lime and natural wood fibre. The panels form the structure of our homes. All of the timber is sourced from sustainable forests. A typical external wall panel locks up over 30kg of CO2e per square metre. Our Panels are BOPAS (Build Offsite Property Assurance Scheme) accredited.
