The fair-faced concrete lower floor of this Passive House on a Buckinghamshire hillside is nearing completion. The timber framed superstructure is due for delivery and erection towards the end of September and will be watertight and draught free a couple of weeks later.

This will be a super-comfortable and cheap to run all-electric house. It does not rely on ideal southerly orientation for solar gains, illustrating the fact that Passive House buildings can be tuned to work for any site. Although connected to the electricity grid, it is being designed with sufficient solar photovoltaic panels to supply its tiny total energy needs throughout the year, illustrating how the dream of a truly zero carbon future is within our grasp.
