Carlton Hotel is located at a major pedestrian and vehicular cross-section in Singapore’s downtown. This extension project includes a horizontal expansion of the hotel’s podium topped by a new 16-storey guestroom tower to complement an existing 26-storey block built in the 1990s.
The project establishes a host of new functional connections between Carlton Hotel and the site’s surroundings, strengthening the presence of the building within its urban framework by means of a ground level entrance rotunda and colonnaded canopy. The double-height canopy unifies new programme with that of existing building and sidewalks, and the corner rotunda houses a civic plaza to address the site’s major street junction. The latter mirrors an existing rotunda located at the opposite end of the site, thereby balancing form and function of the hotel’s ground floor. These new elements are clad in granite to match that of the existing hotel.
While the extension responds formally and materially to the original hotel, the design expresses a clear merger of old and new. As an expression of difference, the new L-shaped tower is clad in spandrel glass, and its block form is broken at one corner to reveal a convexly curved, segmented curtain wall — this comprehensive use of glazing on the facade contrasts with the heavy granite face of the original building, while articulated bay windows establish a complementing pattern. At the fifth level, the new guestroom block is lifted 12m to make way for a sky terrace — an extension to the existing pool deck that opens up views to the city.
The extension holds 287 guestrooms and increases the hotel’s overall room count to 900, supplementing the original 26-storey block and its 16-storey extension also designed by DP Architects in 2001. Additional program spaces include a reception lobby, lounges, ballroom, meeting rooms, gym, and spa.
