Sandwich Para 79

The design of this house explores an interesting characteristic of other buildings in the vicinity, where the principal facade is simple, discreet and devoid of detail, while the rear elevations are more elaborate and expressive.

This characteristic along with the buildings south facing orientation helps to maximise the the properties solar gain and allows for more dramatic architecture, when viewed from the private rear garden.

Seen from the road, north of the building, the form of this Para 79 dwelling is simple and reminiscent of any peg tiled agricultural barn. Moving around the site, these simple distortions create sculpted drama and cleverly resolve the inside and outside spaces.
