Sustainability at stonewood

Whether it’s through meticulous design, focused social landscaping or internal company processes, sustainability is central to what we do.

Sustainability Built In

We build beautiful homes that are not only light and spacious with a contemporary feel, but are inherently sustainable.

Apt for modern living, our homes are fit for the future and don’t compromise on style. Energy efficient, renewable technologies and modern methods of construction are utilised across our developments as standard and combine to build carbon-conscious spaces, promoting a greener lifestyle for our new residents.  

A Fabric First Approach 

All our homes adopt a fabric first approach, meaning high performing fabrics are put at the forefront of the construction process, prioritising performance, comfort and longevity before the addition of sustainable technologies. This modern method of construction is an essential aspect of energy efficient design: the well-insulated, airtight building envelope acts as a barrier to heat loss and gain, reducing the home’s energy demand and therefore minimising operational carbon emissions.

Investing in quality is core to our housebuilding approach; constructing with attention to detail and high-quality fabrics that stand the test of time, whilst reducing maintenance requirements, contribute to the enduring, futureproofed aspect of our homes.

Many of our developments are built using responsibly sourced timber frames. These frames are precision-made in a controlled factory environment to maximise airtightness. This renewable building material locks carbon away in the bones of your home, instead of releasing emissions into the atmosphere. Timber has the lowest embodied carbon of all structural building materials, dramatically reducing the carbon footprint of our homes.

Our developments also incorporate triple glazing which further helps to reduce heat loss from our homes.

Mechanical Ventilation Heat Recovery

Our highly insulated, airtight homes require effective, efficient ventilation systems. MVHRs continuously work away in the background, seamlessly extracting stale air for replacement with incoming, fresh, filtered air. The filtration process removes harmful pollutants and irritants, such as mould, humidity, pollen, dust, carbon dioxide and infections – offering welcome respite for individuals with health vulnerabilities, such as those suffering with allergies or respiratory issues.

The inflow and outflow system includes a heat exchanger that recovers around 90% of the heat from the extracted air for redistribution into the living spaces, perfectly balancing the temperature from room to room and reducing demand on the space heating system.

The MVHR provides superior air quality,  supreme thermal comfort and exemplar energy efficiency to our homes.

Heating & Hot Water

Air source heat pumps are used in all of our developments instead of fossil fuel boilers. The technology compresses air from outside to extract heat to transfer to the inside of the home, even when temperatures outside are cold. This heat is used in the underfloor heating and hot water system. Underfloor heating spans a broader area than traditional radiators, meaning they’re heated to a much lower temperature and have a far lower energy demand.  Supplying this system with green energy means heating our homes can be carbon neutral.

Solar Panels

Renewable electricity generation is possible in all our homes with the inclusion of solar panels. Batteries are available as optional extras, offering flexibility over when this energy is used. By harvesting energy from the sun, reliance on the grid is reduced, offering more protection from unstable fuel prices.

Electric Vehicle Chargers

Charging facilities for EVs are included across all our sites, supporting future home-owners in the shift from petrol and vehicle cars.


Building Lasting Communities

A Stonewood Homes development puts people at its core. Thoughtfully designed landscaping offers social spaces that promote neighbour connection, enabling and promoting community and individual wellbeing.
Communal and recreational areas are strung together with well-placed access points, seamlessly linking the new community to the surrounding area.

Our developments offer an array of housing styles that are in keeping with the local area, giving character and a real sense of place to the new neighbourhoods.

Sustainable Drainage

Water is a precious resource, so managing water sustainably in our schemes is a top priority. Sustainable Urban Drainage Systems are incorporated into the landscapes of our schemes as standard and work to alleviate issues relating to stormwater, such as flooding, erosion and pollution.

Building a More Sustainable Stonewood

At Stonewood, we design, build and craft beautiful places and spaces that leave a lasting legacy. Our mission is to be the most sustainable developer, creating beautiful buildings that are highly sustainable and positively enhance the environment and people we serve now and into the future.

As well as building future-proofed, energy efficient homes, we’re working hard in the background to become a more sustainable business. Find out more about our approach to sustainability.

Energy Efficiency in Our Homes

Our EPC Miniguide

Energy Performance Certificates are mandatory documents that accompany homes built, sold or rented within the UK. The certificates are designed to provide homeowners and buyers with an energy efficiency rating from A (most efficient) to G (least efficient) using a simple 100-point scale.
These simple guides rate the building’s energy efficiency based on the cost of heating and lighting, with a rating for likely carbon dioxide emissions also considered.

Recommended efficiency improvements to achieve a better rating are also included. All our homes are built to be EPC A rated.

EPCs offer a comparable scale between all house types and are a useful initial benchmark for efficiency, however there are some issues with these simplistic tools.

The methodology used to certify homes often leads to variable results, as well as large gaps between reported and actual energy performance.

The calculations prioritise energy costs over carbon emissions, meaning results can often be misleading in terms of the home’s environmental impact. For example, gas boilers are cheaper to run due to the low unit price for gas, so rank higher in the EPC despite the carbon emissions they produce.

Our AECB Miniguide

The AECB Standard has been produced in the UK to promote sustainable, high-performing buildings. The Standard focuses on minimising environmental impact by reducing carbon emissions and promoting energy efficiency through a fabric-first approach as well as renewable energy technologies. AECB estimates that carbon emissions of certified homes can be reduced by 70% compared with average UK homes.

The Standard requires certain key performance metrics to be achieved for the building to be certified.

Airtightness: < 1.5 m3/m2.h

Space heating demand: < 40 kWh/m2.a

Evidence must be provided to the certifiers from throughout the construction process, such as images of building materials used, key thermal bridges and insulation thickness. This ensures the homes are built to the quality they’ve been designed to which reduces the performance gap between designed and built homes.

This Standard sits just below Passivhaus – the world’s leading energy efficiency standard – and can offer huge savings to homeowners on their energy bills.

Our Passivhaus Miniguide

Passivhaus is the world’s leading energy efficiency standard and takes a holistic approach to sustainable homes. Homes are meticulously designed through rigorous modelling that balances insulation, airtightness, and form and orientation with renewable energy, producing a building that uses 90% less energy for temperature regulation.

The Standard sets very tight performance metrics that can only be achieved through high-quality construction with particular attention to detail.

Airtightness: < 0.6 m3/m2.h

Space heating demand: 15 kWh/m2/.a

Similarly to AECB certified homes, photographic evidence needs to be submitted and approved along with an airtest certificate before homes can be certified, to guarantee quality and close the design and as-built energy performance gap.

These homes are Net Zero Ready and save homeowners thousands of pounds on energy bills each year.
