Aldar Properties, Abu Dhabi’s biggest property developer, plans to build 272 apartments and 75 villas and townhouses in the sheikhdom’s capital, Chief Executive Officer John Bullough said.

Aldar has already sold the apartments, Bullough said in a telephone interview today, without identifying the buyer. The other homes will be put on the market at a later date.

“Now we are pressing ahead with working up the construction program for the project and the anticipated completion date is August 2012,” Bullough said.
