The iconic Capitol Theatre will open its doors again in the second quarter of next year, almost 17 years after it screened its last movie in 1998.

The theatre is part of the 542,000 sq ft Capitol Singapore integrated project on North Bridge Road, which will start welcoming visitors slightly earlier at the end of this year.

Its developer Capitol Investment Holdings, a joint venture comprising Perennial Real Estate Holdings' President Pua Seck Guan, Pontiac Land Group's Kwee Liong Seen and Osim's Ron Sim, said the project's building structure has been completed after two and a half years.

"By the end of this year, majority of these components will be operational. This brings us a step closer towards achieving our vision of creating an unparalleled first class integrated development that will drastically change the landscape of Singapore's civic and cultural district," said Mr Pua at a topping out ceremony at Capitol Singapore on Thursday.

The value of Capitol Singapore is expected to be at least $1.1 billion, he added.

When completed, Capitol Theatre's opening act "Singapura The Musical" will be staged by The 4th Wall Theatre Company. The act will centre on former Minister Mentor Lee Kuan Yew's journey as he built Singapore.

As for Capitol Singapore's retail mall, luxury hotel The Patina and residential component Eden Residences Capitol, they will be ready by the end of 2014.

Mr Pua told reporters that shoppers can expect new-to-market retail and food and beverage brands, but declined to comment on how much rental rates would be for retailers leasing space at the development.

On the residential front, Mr Pua let on that one more unit had been sold to a "business associate". The 3,400 sq ft unit was transacted at "over $11 million".

He added that the firm was "not really" holding back sales of its residential units following the multiple rounds of property cooling measures. "Our main business is not the residential component," he said.
