The consortium has been named preferred partner by Barnet council, beating off an Ealing Family Housing Association/PRP Architects team and a bid from Community Housing Association and architect John Thompson & Partners.
A source close to the bidding process said the HTA scheme proposes to demolish all the existing housing in the Marsh Lane estate and build 2000 new homes. The estate now comprises about 500 homes.
John Thompson's plan was similar, but involved the construction of fewer homes, whereas PRP recommended the retention of some housing for refurbishment.
The selection was made after a series of presentations by the shortlisted bidders to the council and residents earlier this month. They submitted their plans at the end of May.
The West Hendon scheme is part of Barnet council's wider regeneration drive. Last month it placed an advertisement in the European Union's Official Journal looking for a registered social landlord partner for its £200m Dollis Valley housing estate scheme.
In the advertisement, the council said demolition, new-build housing and refurbishment were on the agenda. Works on the scheme will start next year.
The HTA consortium declined to comment on the West Hendon scheme. An official announcement confirming the appointment is expected later in the summer.
PRP will work with the local Design Institute to design 450,000 m2 of residential space in Changzhou. The site will include 3000 homes, a school and a kindergarten.
PRP and the local institute were selected to work together because of their different approaches to design. PRP director Andy von Bradsky said: "[The government] decided to mix the best of local practice with an international flavour."
The scheme would be worth around £350m in the UK but in China is likely to be valued at one-tenth that amount.
