Waha Land, the property arm of Abu Dhabi-based Waha Capital, has said that work on the second phase of the Dhs12bn ($3.3bn) Al Markaz development project in Abu Dhabi could begin earlier than planned to meet increased demand for affordable housing and industrial units, Reuters has reported. "The start of phase two will overlap before phase one is completed. We are expecting phase one by the end of 2011," Hazem al-Nowais, CEO of Waha Land told the news service.
