Rebuild and extensive extension of a Victorian house in Brighton to Passivhaus principles achieveing an airtightness test result of 0.35 ACH.

Low energy renovation & extension, Rottingdean
Low energy renovation of a bungalow in Rottingdean including loft conversion and side extension. The existing roof was transformed by stripping back to the frame to utilise all internal space, adding deep rafters alongside the existing to super insulate with 300mm of Warmcell (cellulose insulation). High performance airtightness, windtightness and triple glazed rooflights complete the building envelope.
Roof lights have been located to maximise solar gain and bring light into the stairwell and make the most of the views to the sea and downs. The extension has a similar specification with a garden room and the existing ground floor has been extensively remodelled to improve every space in the house.
Overall significant energy savings and dramatically improved comfort for decades to come.

Sustainable Renovation in East Drive, Brighton
Every room in this Edwardian house in the Queen’s Park Conservation Area of Brighton & Hove, Sussex has been sensitively reworked to provide a home suitable for the 21st century while maintaining the architectural detail and period feel.
A rear extension provides a large kitchen diner with two walls of folding doors onto the garden. The top two floors have been altered in such as way that the visitor is unaware of the changes to the layout, but the changes have dramatically improved the internal spaces, such as the addition of two rear dormers to the top bedrooms.
Sustainability was at the heart of this renovation and measures include high levels of insulation, airtightness detailing, green sedum roof, solar hot water, refurbished sash windows with super thin double glazing and passive solar design. Any risk of overheating is avoided by a timber brise soleil (sun shade), internal blinds within the glazing and high thermal mass along with night time ventilation.
The project was a great success at the Brighton and Hove Eco Open House Event.

‘The flat is fabulous. Many thanks again for making it all happen.’ Trevor, Brighton
Sustainable renovation including rear extension and loft conversion in Shoreham
The ground floor was transformed by knocking through the small kitchen and rear reception rooms and extending to the rear/side to provide a large open plan living space. A fully glazed roof and folding doors flood the space with light.
The loft conversion provides a welcome additional bedroom and was squeezed in by dropping the first floor ceiling and benefits from high levels of insulation and airtightness.
Other sustainable features include triple glazing to the folding doors, under floor heating and a bathroom fan with heat recovery all contributing to improved comfort and lower energy bills. Lime plaster and natural breathable paints to the ‘bungeroosh’ walls ensure the 19th century walls continue to ‘breathe’
“We are delighted with the way our house has been remodelled and are very happy that we chose Jim.” Peter Riley, Shoreham-by-Sea
Eco Remodelling in Brighton
Rear extension & Basement Conversion in Brighton
The shallow curved roof maximises the space within the extension while minimising the visual impact to the neighbours at the eaves and the pre-weathered zinc mimics lead thus blending in with the surrounding Georgian buildings.
Excavation of a new basement level will provide two bedrooms and an en-suite while the new ground floor will provide an open plan kitchen diner. Retaining the existing patio down to the basement level will allow light into all rooms and the ground floor will have a huge roof light over the internal stair well and kitchen.
Low Energy Renovation Brighton
Options being considered include solar PV, solar thermal, wood burning stove and MVHR in conjunction with high levels of airtightness.
