A showhome built to promote a prize-winning home design has had more than 1500 visitors in a matter of weeks.

The Christchurch showhome is The Cantabrian, built from a design intended as suitable and affordable to build on TC3 land.

The design was chosen when state-owned Southern Response, set up to handle claims for collapsed AMI Insurance policyholders, held a design contest with the New Zealand Institute of Architects last year.

The winner was a design by Nelson-based architect Richard Sellars. His design has now been built for the first time as a showhome open for public viewing in the suburb of St Albans.

The Cantabrian has been approved to be built anywhere in the country with only consents for site-specific foundation and services needed.

House building companies are already looking to launch their own version of the house. All homes carrying The Cantabrian brand will need to be endorsed by Southern Response.

One company, Jennian Homes, has already developed its own version of the house and will build the first in the Christchurch suburb of South New Brighton.

Southern Response chief executive Peter Rose expects other housing companies will follow.

"What began as a technical response to building on vulnerable land has developed into very real solution for safer, smarter and more secure houses for Cantabrians," Rose said.

"To see a building company so enthused by the concept to commercialise it, is just fantastic."
