Barrenger Road, London.

Designed by Tate Harmer Architects, this new buildingmeets the Passivhaus design criteria, working within the restrictions of a tight suburban site by introducing substantial glazing to the rear of the property whilst maintaining the look of the existing faade on the street. A central lightwell will ensure that there is excellent daylight and natural ventilation within the deep plan, without overlooking to the surrounding neighbours. This energy efficient new-build home will be a subtle but unique additional to the area.

Beacon View - Dundon Passivhaus

Set at the foot of a wooded hill the house has been designed to make the most of the fantastic views across the Somerset levels. The windows frame different views creating an experiential richness that extends the domain of the interior into the surrounding landscape.The form of the house relates to nearby agricultural buildings rather than the suburban houses in the village. A gently sloping roof extends beyond the building envelope on three sides to create sheltered outdoor spaces that blur the distinction between house and garden. This welcoming, sheltering gesture works in harmony with the energy strategy by providing summer shading to the large windows.Green oak columns support the roof, tied back to the main timber-framed structure which is clad in green oak. The wall construction is vapour permeable to moderate humidity and create a healthy internal atmosphere.

Bourne Lane

Built on an urban infill site in Tonbridge, this high quality, low energy dwelling takes inspiration from the towns brickmaking past, reflecting patterns and details of dark clinker bricks used in some of the town's historic buildings. Sections of Siberian larch add further architectural interest. The design and layout respond to the slightly sloping site, with the house nestled below the main parking area. A large roof window perfectly frames the view of a protected lime tree. An air source heat pump provides heating and hot water and 4kw of solar panels provide electricity. The measured air tightness is 0.34 ACH at 50Pa and fresh filtered air is brought into the building by a Paul Novus 300 MVHR. The structure is a highly insulated (Warmcell) timber frame sitting on an Isoquick 300mm-deep insulated slab. Natural and low/zero VOC materials, such as zero-added formaldehyde Smartply, keep the house healthy as well as comfortable. The zinc roof is 100% recyclable at the end of its life.

Bowmans Lea

A 1978 mid-terrace townhouse in London has become the first certified step-by-step EnerPHit retrofit in the UK. The 3-storey property is both home and project of architect Harry Paticas, of PHT member Arboreal Architecture.Step-by-step EnerPHit is designed to facilitate long-term deep retrofit projects, by planning measures from the outset which will lead ultimately to achievement of all the usual EnerPHit targets, however many years the project may take to complete. Once the first step in the plan has been successfully accomplished, and demonstrable energy savings of a minimum of 20% (easily surpassed in this case) have been achieved, the whole project can be pre-certified.
