Passive House Plus, Kent

One of the UK's most ecologically advanced houses. An all-electric, timber-framed Passive House Plus.

A comfortable, healthy, 3-phase all-electric family home designed to meet the ecological imperative of our time, with low embodied carbon construction and extraordinarily low operational energy use.

With fundamentally the same shell and operating system as our completed PH+ in Hertfordshire, including concealed automated solar shading and active cooling if required. It is designed to be extremely efficient, and to contribute more energy to the wider community than it imports from the national grid each year.

Enhanced resilience is achieved by an 18 cubic metre rainwater harvesting tank, together with 12.8 kWp solar array and 3-phase battery storage. 

The house is carved into its site to meet a planning requirement to minimise its visual impact in the landscape. The cost of this requirement is greatly reduced, compared to Lark Rise, because the retaining wall is a garden wall rather than integrated into the construction. Thus reinforced concrete is not required in the construction of the walls.

The kitchen, living spaces and principal bedroom are on the first floor to take advantage of the views. The first-floor dining space opens on to a bridge leading to an outdoor terrace and upper level of the garden. There are three / four further bedrooms and ancillary accommodation on the lower floor.

This is the third in a series of high-performance, timber-framed, ecological, all-electric houses, with several more currently on the way. It is expected to be completed in spring 2022.
