Chelsea-Warren Construction has served as the general manager during the construction phase of more than six NCC housing developments, including high-rise apartment buildings for seniors, family townhouses and single family homes.

The entity played a key role providing project management services for the multi-million dollar housing rehabilitation of the Manor properties in Newark, which resulted in major home improvements for more than 500 low- income residents, as well as rehabilitating four other Newark properties: Commons, Douglas Homes, Gardens and Roseville.
