We take into account many factors when future-proofing our homes, including economics and affordability, design expectations, changing demographics and household composition. Future-proofing our homes also means managing climate change risks, such as flooding, overheating and water shortage.
Flooding is the major climate change risk in the UK, whether from surface water runoff or from river and coastal floods. In line with legislation, we undertake flood risk assessments and prepare appropriate flood and water management plans on all our developments. In 2015, we introduced Sustainable Urban Drainage Systems on 53% of our developments. We work closely with our partners, consultants, and contractors to develop effective mitigation and protection measures.
The measures we designed to protect homes at Bath Western Riverside underwent the best possible test early in 2015 when torrential rains hit the South West. The flood compensation scheme we put in place did exactly what it was designed to do and protected the development when the Avon rose over its banks. The specially designed area called ‘the Scoop’ allowed the excess water to collect safely before gradually subsiding back into the river without threatening homes and buildings.

As temperatures slowly rise in the UK the risk of overheating in homes becomes more serious, especially in well-insulated new homes. While airtightness and low energy bills from highly insulated new homes are good news for customers, we must balance this with a design and features that ensure our customers can still enjoy a well-ventilated, comfortable living environment.
100% of our homes are assessed for the risk of excessive solar gain. We also carry out a full dynamic heating analysis on relevant sites to understand the risks of overheating. These two assessments enable us to incorporate different features to help reduce the risk of overheating in the home, by for example, changing the solar transmission of the glazing or using man-made and natural shading. Our detailed evaluation of the five low-carbon AIMC4 homes we built at Noble Park, Epsom, showed that we’re getting the balance right between how airtight the homes are and the fresh air quality. The occupants found their new homes are spacious and pleasant to live in, while also being comfortable in all seasons.
Water shortage is a growing issue worldwide, made worse in some regions due to changes in the global climate. It’s vital that homes are designed with features to help occupiers use water wisely. Almost 100% of our new homes meet a very high standard of water efficiency (105 litres per person per day) by incorporating A-rated appliances and other water-saving products such as dual flush toilets, mixer taps and water butts.
