What do you get when you combine renewable energy technology with good, centuries old building techniques? A zero-carbon building – that’s what.

Developed by University of Cambridge architects (and recently featured on Channel 4’s Grand Designs program in the UK) as a prototype for future living – the ‘arch’ is based upon a 600 year-old design that retains heat from the sun while cooling naturally in the summer.

Solar panels on the roof and a woodchip boiler provide for extra energy needs. The dome-like design is based upon a medieval technique, originating in Spain, known as timbrel vaulting.

The four-bedroom eco-house cost around $800,000 to build however, with the price of renewable energy set to fall, it could be a more affordable option for the future.

The building materials include timber sourced locally and recycled newspaper for insulation. It’s makers claim it is easy to build as the arched house is a single vault spanning 65ft, covered on the outside with earth and plants to help it blend in with the rural surroundings.

I don’t know about you – but I quite like the look of it myself  (although I half expect the Noo-Noo to appear from behind at any minute!)
