Recent projects in Bromley and Orpington
On Lancaster Close in Bromley (BR2) we were main contractor on a whole-house energy upgrade of a detached home: external wall insulation with a silicone render finish, an air source heat pump, solar PV and a Baulogic KNX smart home system. The house now has an EPC rating of B (89) and an A environmental impact rating. Read the Lancaster Close case study.
In Petts Wood, Orpington, we built a complete new-build house, from groundworks and structure through to the finished home.

Building on Bromley, Beckenham, Chislehurst and Orpington homes
The borough has a wide mix of homes: Victorian and Edwardian houses in Beckenham, Shortlands and around Bromley town centre, large detached houses on generous plots in Chislehurst, and 1930s semis and detached homes across Orpington and Petts Wood. These houses suit big rear and side extensions, hip-to-gable loft conversions, new builds on larger plots and whole-house energy upgrades. Parts of Chislehurst, Beckenham and Petts Wood are conservation areas, with rules on extensions, roofs and materials. We plan for these from the start: party wall notices, structural design, and planning or permitted development with Bromley Council.
