Fletcher Building is proposing to build temporary accommodation for extra workers and displaced households in Christchurch.
The company says it has submitted proposals to the Government about temporarily housing extra workers and displaced households while the rebuilding is done.
Infrastructure chief executive Mark Binns says the company would build up to three makeshift villages to house up to 900 workers sent to Christchurch to fix damaged properties.
He says Fletcher Building is also proposing to build up to 350 temporary homes for displaced residents.
Mr Binns says the Government needs to make sure planning is a priority to ensure a smooth rebuilding process.
Fletcher Building estimates rebuilding the city will cost $5 billion more than Treasury's recent forecast of $15 billion, though Mr Binns says it is still too early to put a concrete figure on the final bill.
