Emperor International Holdings plans to spend HK$500 million developing, the Lido Complex, a retail project at Repulse Bay.
Executive director Tony Tse Wai-chuen said the project could go ahead at full speed now that ownership of the site was finally unified.
Many shops in the commercial and shopping complex had different owners and it took the developer more than five years to acquire them all individually.
The last shop was bought from the McDonald's group for HK$36.8 million two months ago.
Mr Tse said the final property transaction would be completed at the end of November, meaning ownership of the entire site would then be in the developer's hands.
Two years ago the company received Town Planning Board's approval to build a three-storey retail mall on the site.
Mr Tse said the project would still need some amendments in relation to its appearance and designs.
