Sea Views • Rooftop Wedding Venue • Fireworks Display
At 1-Altitude Coast, your wedding feels like a dream unfolding by the water. Perched atop The Outpost Hotel in Sentosa, our rooftop venue surrounds you with golden sunsets, a soft sea breeze, and the kind of intimate, sky-high setting that makes saying “I do” feel truly unforgettable.
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 day to life with warmth, care, and effortless coastal charm.
Why couples love us:
Make your special day not just a wedding, but a memory woven with views, romance, and ease.

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.
Your ceremony deserves a setting as meaningful as the vows you’re making. Our floating water stage creates a dreamy, almost cinematic moment. A gentle shimmer of water beneath you, the horizon unfolding ahead, and all eyes on you for the most important walk of your life.

As the sun sets and your celebration begins, the atmosphere shifts into something magical — soft lights, warm laughter, clinking glasses, and a night sky waiting to sparkle. With fireworks lighting up the Sentosa coastline, your evening unfolds like a story worth remembering forever.
When the vows have been said and the sun has set, the energy shifts and the party begins. Celebrate into the night with poolside beats, ocean breeze, and the unmistakable thrill of your first party as a married couple.
