Bunnings is expanding its range of flat-pack homes, 72 of the structures are now up throughout New Zealand and a list of 21 approved builders has been released.

A Bunnings spokesperson said demand was growing for the products, starting from $69,000 for the Clever Living Co. product, not including the land, connections to services, site works, landscaping or other costs.

In May, Bunnings said around 50 housing packs had been sold, rising to 72 now and "many more under

"It's particularly popular among retirees and first home buyers with young children," he said of that layout where the bedrooms are on the sides and the kitchen/living/dining area is in the middle.

Consumers could not necessarily buy and build one of the places, the spokeswoman said.

"People can't drive up to their local Bunnings with a trailer to buy one. Instead, this is a high-quality design and materials package. Bunnings Trade sells the design and materials packages to approved Clever Living builders which we have authorised to build our Clever Living designs," the spokeswoman said.

"It's the builders themselves that provide the price to customers, with costings dependant on site, and the price comes as a complete build and design package," she said.

But one building consultant, Alan Light of A L Building Consultants in Auckland, challenged Bunnings' claim that people could not build the Bunnings houses.

"DIY is alive and well," he said. Non-licensed non-builders could put up their own Bunnings flat-packs under certain conditions including if they intend to reside there, did the building work themselves or used unpaid friends - barring developers from using the loophole.

A clause in the law allowed for owner-builders to be exempt on restricted building work, meaning they could carry it out without being supervised by a licensed building practitioner, Light pointed out.

In May, a Bunnings spokesperson at the chain's Melbourne headquarters said the products had been built in Northland, Auckland, the Waikato, Taranaki, exported to Rarotonga, Palmerston North, Gisborne, Hawkes Bay, the Bay of Plenty, Tauranga, Wellington, Central Otago, central South Island, Otago.

Prices range up to $113,541 plus GST for the four-bedroom 106sq m not including land or services such as power, stormwater and water.
