The Grand Hyatt Singapore offers a distinctive blend of design and ambiance across its 699 rooms, which are divided into two uniquely styled wings. The Grand Wing, featuring 407 rooms designed by STRICKLAND, embraces an urban and heritage-inspired aesthetic. These rooms incorporate open-concept layouts and comfortable sofa areas that transition smoothly from workspaces to social zones. Design elements include Peranakan-inspired details and modern geometric patterns, complemented by Patagonia stone bathrooms. Throughout the Grand Wing’s corridors, an octagonal motif pays homage to the building’s original architecture, connecting the contemporary restoration with the hotel’s historical roots.

In contrast, the Terrace Wing presents a more tranquil, resort-like atmosphere with 292 rooms crafted by Grant Associates. This section is enveloped in lush tropical greenery, with koi ponds and waterfalls designed to evoke the Japanese practice of shinrin-yoku, or forest bathing. The rooms emphasize calm with their neutral color palettes, ice-green marble accents, and wooden furnishings. Many accommodations in the Terrace Wing include window alcoves fitted with daybeds, offering guests a relaxing space to enjoy the scenery. Although the hotel overlooks Orchard Road, the inviting environment within the Terrace Wing encourages guests to remain immersed in its serene surroundings rather than venture outside.
