ENGLISH Partnerships has caved in to industry pressure and extended the deadline for its £60,000 house competition by two weeks.
All 33 bidders now have until July 15 to come up with designs for the competition following a change of heart from the agency.
Deputy Prime Minister John Prescott is the driving force behind the scheme at Oxley Park in Milton Keynes.
House builders including Persimmon, Westbury and Linden all complained that the short tendering period would affect the quality of their bids.
Persimmon northern region chairman David Broadbent said: 'The decision has been very well received here.We could have made the deadline but it was the quality of the submission we were concerned about.'
English Partnerships corporate strategy director Trevor Beattie said: 'It is meant to be a challenging competition but we want good quality submissions.'
Bidders were initially given only five weeks to work up their plans.
