The largest is the £16.4m contract for Bell Green, located in Sydenham, Lewisham, which will see Willmott Dixon design and build 156 apartments and commercial space.
The housing will be completed in July 2012 and includes 85 homes for social rent and 71 for shared ownership.
This scheme is part of a multi-phase redevelopment programme on the former Bell Green gas works site that will create new homes, businesses and employment within Lewisham.
The second scheme, Gosterwood Street in Deptford, is worth £6m and consists of 38 flats available for affordable rent and will be completed in August 2011.
This site is immediately adjacent to a £13m development of 89 flats and commercial units built for Circle Anglia in May 2010.
Willmott Dixon is also working with Circle Anglia to transform Mardyke estate in Rainham into Orchard Village, replacing several large 1960s-built blocks of flats with new living accommodation and recreational space.
