Croxley Green Station

In the Autumn of 2008 we carried out the Refurbishment & New Service Installation works to a large Flat owned by TFL over Croxley Station. With our alternate heat source specialist Greentech we installed an air source heating system for the property.

The Tree House, Clapham

Well insulated, air tight timber framed two-bedroom house on 6.6m wide site with access restricted by the eponymous tree. The design strategy aimed to achieve a 'zero carbon' performance and the house was built to stringent standards. This included high performance windows and whole house mechanical ventilation. The energy systems include rain water recycling, photo-voltaic generation of electricity and a system of hot water generation that combines a solar thermal panel with a vertical ground loop heat pump.

Sunnyhill Primary School

27th April 2011

This exciting project is a 250m2 School Extension for Lambeth Education.
A piled Foundation solution proved a highly cost effective solution combined with our off-site Powerwall Space Frames technology.

We have supplied and installed the building using off-site volumetric pods. The installation of the pods successfully took place in 2 days on the 21st & 22nd April.
