Countryside Properties said it expects to deliver 500 modular timber-framed homes this year after its factory in Warrington went into full production last month.
The housebuilder said the plant's production capacity would be up to 1,500 homes a year.
In a trading update ahead of the group reporting its half year results on 16 May, chief executive Ian Sutcliffe said that with the factory now operational Countryside was in a good position to expand beyond its main locations of outer London, the south east, the north west of England, Yorkshire and the Midlands.
Thanks to last year's £135m acquisition of Westleigh, Countryside said it had ramped up house completions by 42% to 2,362. Excluding Westleigh this growth figure was a more conservative 8%.
Its private average selling price dipped 4% to £377,000, due to what Countryside said was an increased contribution from its regional businesses, following the Westleigh deal.
Westleigh boosted Countryside's partnerships division, which completed 1,889 homes, up 61%.
Housebuilding delivery was marginally down at 473 units from 483 a year ago.
Total completions for the year are forecast to be around 5,700 units.
