Allen Jack+Cottier (AJ+C) has promoted David Nelson to senior associate.

Nelson has made a great contribution to AJ+C since joining the firm in 2005, taking on a wide spectrum of projects from high and medium density residential developments to adaptive reuse of heritage buildings and most recently, social housing projects.

“David has shown strong leadership and commitment to the job for the past four years,” said AJ+C’s CEO Reg Smith. “He is not afraid to take on new challenges and acquire new skills by embracing a wide variety of projects.”

Nelson has worked extensively on the firm’s residential projects, including Vinosa, a $23 million, 55-apartment project at the former Prince Henry Hospital site in Little Bay for Stockland and Pavillions on the Park in St Leonards, a $30 million 185 apartment block for Australand.

Nelson’s expertise also includes adapting heritage sites to new uses, having worked on Building 6 and 10 at Cockatoo Island, which was transformed from a heritage office and workshop into a contemporary office, hospitality and studio space for the Sydney Harbour Federation Trust.

He is leading the social housing projects won by the firm this year, which comprises 191 dwellings across 10 sites in southwest Sydney and is also working on Botanica, a conversion of the heritage-listed Lidcombe Hospital into nine apartments, which commences construction in 2010.
