The developer of 139 terrace homes on Main Street, Mount Annan believes increased traffic will not be an issue around the site.
Sunland Group recently beat Camden Council in a lengthy court battle over the controversial site next door to Mount Annan Marketplace.
The Land and Environment Court decided to rule in the developer's favour.
Sunland Group managing director Sahba Abedian said early construction works on the project - called Montaine Residences - would commence in November, with the first residents expected to move into their new homes in 2021.
"No adverse traffic impacts are anticipated due the site's excellent proximity to public transport and local amenities, and improvements already under way to local infrastructure," he said.
"During the approval process, both the Land and Environment Court Commissioner and Camden Council's own traffic experts agreed that the development provides 'more resident and visitor parking than the [Development Control Plan] requires'.'
Mr Abedian said the original development application had been amended, reducing the number of homes from 143 to 139.
"Montaine Residences addresses 'the missing middle' in Sydney's south-west by providing high quality, diverse housing options to first home buyers and owner occupiers," Mr Abedian said.
"This site is also located in an environment which offers access to high levels of service and amenity in Mount Annan, with its proximity to two major shopping centres, local schools, and public transport.
"Importantly, our homes and our masterplanned environments are created in a way that they are connected to, and contribute to, community life through enduring design excellence and a significant investment in landscaping and open spaces."
A Sunland Group spokeswoman said more than 35 per cent of the total site area was dedicated to communal green space.
"The open space areas, which include two pocket parks complete with landscaped community facilities including picnic shelters and barbecues, will provide a range of recreation opportunities for residents," she said.
Residents and councillors expressed concerns throughout the lengthy approval process about traffic impacts, parking around the site, the character of the site, noise and water.
The 1-5 Main St, Mount Annan: Fairer Outcomes For All Facebook group has been campaigning against "over-development" of the site since 2014.
A spokeswoman took to the page to voice the group's disappointment with the court's decision last month.
"We all knew something would eventually get built on this site at some point, and after five years of hard effort by the community and council, we would have hoped it'd be something aligned to what sits around this key central part of our town," the post read.
"Best of luck to those fellow residents who live in and around the block, and to the rest of us who must pass by/park/shop next to it every day."
The final homes are expected to be completed in late 2022.
