Integrated Residential Projects
A selection of projects where integrated energy systems were designed as part of the building from the outset.
📍 New Build — New Milton, Hampshire
High-performance new build achieving net-zero annual energy cost
A high-performance residential new build designed to minimise energy demand while maintaining excellent internal comfort. High levels of insulation and MVHR reduce heat losses and improve indoor air quality. Extensive solar PV enables the home to achieve a net-zero annual energy cost.
The design includes adaptable internal layouts with movable walls allowing spaces to be reconfigured to suit occupancy. Ceiling heights of 3 metres enhance the sense of space and natural light. Underfloor heating is cast directly into the main structural slab, increasing thermal mass and enabling stable internal temperatures with long-lasting heat retention.
📍 New Build — Lymington, Wiltshire
Future-proofed home managing grid costs and summer temperatures
The client required a future-proofed home capable of managing rising energy costs and increasing summer temperatures, while significantly reducing reliance on the electricity grid. A ground source heat pump supplied by boreholes provides low-temperature space heating in winter and active cooling in summer.
The system is powered primarily by on-site solar PV, with battery storage maximising self-consumption. Surplus electrical generation is automatically diverted to preheat domestic hot water and the heating buffer, increasing overall system efficiency and reducing operating costs.
📍 Listed Refurbishment — Salisbury, Wiltshire
Near-zero energy bills in a listed property with column radiators
This listed property underwent a comprehensive refurbishment replacing the existing heating system. The use of high-temperature heat pumps enabled the retention of column radiators while still meeting the full heating demand of the property — aligning with the architectural character of the building without compromising performance.
Both heat pump units were carefully screened from view, meeting the aesthetic and planning requirements of the listed building while maintaining system accessibility. A coordinated system combining heat pumps, solar PV and battery storage has resulted in energy bills reducing to near zero.
📍 New Build — Shaftesbury, Wiltshire
Net-zero operation serving house and swimming pool
A large new-build designed with the objective of minimising long-term energy demand and achieving net-zero operation. MVHR reduces the overall heating load while a suitably sized ground-mounted solar PV array provides renewable electricity to support year-round operation including a swimming pool.
A key design challenge was the extended distance between system components. Pipework, cable routes and thermal losses were carefully accounted for within the design to ensure system efficiency, responsiveness and long-term reliability across the site.
📍 Refurbished House — Blandford, Dorset
Stone-built property with heating and summer cooling
This traditional stone-built property underwent a comprehensive refurbishment replacing the oil-fired heating system with a heat pump solution. High-temperature heat pumps capable of delivering flow temperatures up to 85°C were selected, allowing column radiators to be retained alongside underfloor heating while meeting the higher heat losses associated with solid stone walls and floors.
The system was also designed to provide active cooling to selected rooms on the most exposed, south-facing elevations, improving summer comfort without compromising the overall heating strategy.
📍 Refurbished Cottage — Shaftesbury, Wiltshire
Lake-source ground source heat pump for a stone-built cottage
This stone-built cottage, located adjacent to a large lake, was refurbished using the lake as the energy source for a ground source heat pump. Heat extraction is achieved via ground loop pipework floated across the lake before being carefully weighted and positioned on the lake bed.
A critical factor in the success of this approach was the assessment of water flow into and out of the lake. Adequate circulation is essential to ensure heat extraction does not exceed the lake's ability to replenish energy naturally — protecting both the system's reliability and the lake environment.
📍 Existing House — Studland
Cascaded heat pumps for house and indoor swimming pool
This existing residential property required a future-proofed solution to manage the heating demands of both the main house and a large indoor swimming pool. A cascaded air source heat pump arrangement was selected to share the heating load efficiently, ensuring balanced run hours and improved system longevity.
The heat pump cascade is configured to distribute demand evenly across all units, maintaining similar operating hours and providing redundancy during periods of high demand. Solar PV generation further reduces operating costs and supports EV charging, helping to offset both heating and ancillary energy consumption.
