Summary

Ruth and Mark bought this site in 2013, with existing permission to convert the cowshed and

outbuildings to residential. However, the design was ugly and unworkable, so they collaborated with local architect Sally Williams to produce a design for a far more practical  and handsome new build timber building to the highest standards of sustainability. Despite oppostion from the planners, support from neighbours and the inspirational design won over the planning committee and building eventually began in March 2016.

 


The site is just south of Plumpton racecourse overlooking the South Downs and the house has

been designed to be very low energy, both in the energy needed to run it and embodied in its

construction. The building uses mainly natural materials and has a 500mm thick heavily insulated walls with an I-beam structure, which is infilled with loose woodfibre insulation and clad externally with woodfibre board insulation beneath the attractive

oak finish. Even the roof uses natural materials, with its cedar tiling.

 

Heating also uses natural resoures, being supplied by a ground source heat pump

extracting heat from two deep boreholes. The electricity used to run this is largely offset

by the 4kW of solar panels on the roof, which generate over 4000kWh pa.

 

Eventually the house will switch to its own well water which can be easily treated to meet all

needs.
