At 1-Altitude Coast, every celebration feels like a dream unfolding by the water. Perched atop The Outpost Hotel in Sentosa, our rooftop venue brings together golden sunsets, soft ocean breeze, and an intimate setting perfect for saying “I do.”
Picture exchanging vows on our floating water stage — gentle waves beneath you, the open horizon ahead, and your closest loved ones gathered around. As night falls, the celebration continues under the stars with heartfelt toasts, shared laughter, and fireworks illuminating the Sentosa sky. From romantic solemnisations to sunset receptions and late-night after-parties, we’re here to bring every moment of your wedding day to life with warmth, care, and effortless coastal charm.
-Sea-kissed Vows: Say “I do” with sweeping views of the Singapore Straits — intimate, elevated, and breathtaking.
-Floating Water Stage: A magical, one-of-a-kind aisle that lets you walk (almost) on water.
-A Night to Remember: End your night with fireworks across the Sentosa skyline and toast to your new forever.
There’s something timeless about standing above the water, surrounded by sky, breeze and the soft glow of Sentosa. Our rooftop venue gives your wedding a sense of calm and romance — a beautiful space where every moment feels lighter, brighter, and full of promise.

"A big thanks to Joan and team at 1-Altitude Coast for the wonderful wedding experience! The wedding turned out to be everything we hoped for, absolutely recommended!"
"We had a great experience hosting our wedding at 1-Altitude Coast. Loved the innovative idea of having a mock wedding so we can experience how our guests might experience our wedding. The food was great and there was also a complimentary wine and live station tasting. One of the determining factors that drew us to the venue is the option of having a water stage which we absolutely loved although we did have a lot of anxiety because it is subjected to weather conditions. But overall the venue and ambience was great and we felt that it was almost the perfect wedding that we were envisioning. Of course, it was possible thanks to Joan and her team who were with us throughout the journey. Joan herself also stayed late into the night of the wedding to help us out. Much thanks again to helping us create such a dreamy wedding!"
