We are perhaps best known for developing an excellent cost/performance type of timber frame technology called AvalonTM Closed Structural Insulated Panel System, link to SIPS diagramsa closed panel SIPS, used in such houses as the Stirling Home on Grand Designs.

'Closing' the panels mean we finish both sides of the wall in the factory with the service conduits and electrical back boxes preinstalled. This takes complexity, labour and time away from the uncontrolled building site environment which saves money and mistakes.

It also allows us to put up a 1000 sq ft a week using 2 people - saving even more money. So, an average house is up in 2 weeks to a better quality than can usually be achieved on-site.

Our philosophy is to try to keep the best parts of a 1000 year old technology and improve it with new technology where it the cost/performance equation merits it.

Consequently, as well as developing the AvalonTM Structural Insulated Panel System (SIPS), we work with a range of traditional and advanced building methodologies, often combining the two.

Our continuing R&D program has developed variants of the Avalon SIPS Timber Frame:


AvalonTM Über SIPS

a very high tech content in our eco-friendly panels; the fasted build methodology as the panels are made off-site closed with the services already in, and do not need plastering. This saves a lot of money and time.


AvalonTM Hempcrete SIPS

essentially, the Über SIPS panel modified to take a hemp/lime mix which has structural and insulative properties.


AvalonTM Bale SIPS

similar to the Hempcrete, but with treated, highly compressed straw bales.


Other types of Timber Frame

    Post and Beam (with our partners North Woods Joinery of Vermont, USA)

    Green Oak

    Log Cabin ( with our partners Riverbend Log Homes, Canada)


Our expertise and products currently cover (we are trying new things all the time) the following traditional build methodologies:


Traditional Products

    Cob (cay and chalk)

    Rammed earth


Extreme Products

    Rubber tyres & Garbage - a particular hero of ours, see architect Michael Reynolds' work at http://life.gaiam.com/gaiam/p/Garbage-Warrior-Turns-Trash-Into-Houses.html
