We support self-builders; designing, obtaining planning permission, demonstrating compliance with building regulations, preparing construction documentation and helping with project management.
We carry out buiding performance modelling using PHPP (Passive House Planning Package) and thermal bridge modelling of construction details using THERM.
Many projects we embark on have planning permission already; we assist with taking them through the remaining stages, to completion. Sometimes we are asked to assess a design for compliance with the Passivhaus standard, and often it is possible to bring them up to the standard with minimal amendment.
Much of our new-build work is with Touchwood Homes and Williams Energy Design, forming an unique integrated team achieving consistently high-performing homes, many to Passivhaus standard. Our favourite form of construction comprises engineered timber frames with cellulose fibre insulation in a 'breathable' structure. This combination of materials is very robust due to its vapour permeability and has a very low environmental impact.
We also have considerable experience of renovating and extending old buildings, in particular the Victorian building stock that makes up much of London.
Since 1993 the company has been involved with over 200 projects. Most of them are Over 80 of these have been built, or are now under construction.
