Echo Barn  Para 55

Completed in 2017 this large family home, adjacent to listed farm buildings, was built on a disused agricultural plot in the Kent countryside. The veil of louvres wrap around the main house and give the sense that this may still be an agricultural barn.

Two single storey timber and mathematical tiled barns define a public courtyard on entering the site and a private courtyard on the south east side of the house.

The PV-T panel mounted on the roof harness solar energy as electricity and heat. The heat is extracted and dumped beneath the Para 55 building into the Earth Energy Bank, inter seasonal heat store which will heat the house during the winter months.

The electricity is used on site and stored in a battery to be used during peak hours in the evening.
