Rooftop Alfresco Deck (Poolside)

The Rooftop Alfresco Deck is an alfresco, open-air venue set beside the property's pool, meaning it is exposed to outdoor conditions. Weather contingency options — such as tent or marquee coverage, or an indoor backup space — should be discussed directly with the 1-Altitude Coast team when planning an outdoor event on Sentosa Island.

Capacity figures for the Rooftop Alfresco Deck have not been independently confirmed. Guests numbers can also vary depending on the event format — a cocktail-style reception typically accommodates more people than a seated dinner. The 1-Altitude Coast events team is the best contact for confirmed capacity numbers in the layout relevant to your event.

The poolside alfresco setting, with its coastal Sentosa backdrop and open-sky atmosphere, is well-suited to wedding solemnisations and outdoor ceremonies. 1-Altitude Coast should be contacted directly to confirm ceremony packages, licensing considerations, and available setup configurations for weddings.

Catering arrangements, including whether in-house catering is provided or external vendors are permitted, should be confirmed with the 1-Altitude Coast events team. Details such as menu options, dietary accommodations, and beverage packages are best discussed during the initial inquiry and site visit.

Outdoor events in Singapore, including those on Sentosa Island, are subject to noise regulations and may have curfew requirements for amplified music. The specific rules applicable to the Rooftop Alfresco Deck — including permitted sound levels and end times — should be confirmed with 1-Altitude Coast before finalising entertainment arrangements.

Sentosa Island is accessible by road via Sentosa Gateway, by the Sentosa Express monorail from VivoCity/HarbourFront, and by cable car. The island is approximately 15 to 20 minutes from Singapore's central business district under typical traffic conditions, making it reachable for most guests without requiring an overnight stay.

Sentosa Island has parking facilities, but specific parking arrangements for 1-Altitude Coast events — including valet options, designated lots, and any associated fees — should be confirmed directly with the venue team when planning your event.

As a poolside alfresco space, the deck can generally be styled with florals, lighting, and thematic décor, though there are likely safety guidelines around installations near the pool area. The 1-Altitude Coast team can advise on what is permitted, recommended suppliers, and any restrictions that apply to the space.

AV setup requirements for outdoor events differ from those of indoor ballrooms, and the Rooftop Alfresco Deck's specific AV provisions — including sound systems, screens, and lighting — should be discussed with 1-Altitude Coast directly. They can advise on in-house equipment and whether additional rental suppliers are needed.

Whether 1-Altitude Coast offers on-site overnight accommodation should be confirmed with the property directly. Sentosa Island has a wide range of hotels and resorts in the immediate vicinity for guests who wish to stay overnight after an evening event.

The deck's open-air, poolside setting on Sentosa Island gives events a destination resort character that a standard indoor banquet hall cannot replicate. Guests benefit from natural coastal surroundings, evening breezes, and a backdrop that is visually compelling especially at golden hour and into the night — all of which reduce the reliance on heavy internal décor to create atmosphere.

The Rooftop Alfresco Deck is well-suited to corporate events where a relaxed, out-of-office environment is desired — including product launches, client entertainment evenings, and team appreciation functions. The island location adds a destination quality that distinguishes such events from those held in conventional city-centre venues.

Availability and pricing for the Rooftop Alfresco Deck can be explored by contacting the 1-Altitude Coast events team through the official website at 1-altitudecoast.sg. It is advisable to provide your event date, approximate guest count, and event type to receive the most relevant information.

Booking terms, deposit requirements, and cancellation policies vary by event type and date, and are determined by 1-Altitude Coast at the time of contracting. Prospective clients should review these terms carefully with the events team before confirming a booking.
