The World's Largest Overwater Villas (2026)

Why it leads: named for the Astor who built the original St. Regis in New York, the estate keeps faith with that grand-hotel lineage at a scale the founder could not have imagined. Marriott publishes it at 1,726 square metres — the largest single overwater figure we can attribute to a named source. The three bedrooms occupy two floors above the lagoon, served by a 92 sqm pool, two further plunge pools, a private gym, a home cinema, a show kitchen and three dedicated staff rooms, all of it watched over by the house's signature St. Regis butler.

Who it suits: a multi-generational family or a principal travelling with staff, for whom the estate functions less as a suite than as a private wing of the resort.

Honest note: the title rests on a published figure, not an audited survey, and the margin over second place is a single room's worth of floor. Read 1,726 sqm as “the largest we can document,” not as a settled world record.

Why it's here: for years the standard answer to the question this page asks. Gili Lankanfushi — an enduring barefoot grande dame of the Maldives, its villas built almost entirely of timber and rope — sets The Private Reserve adrift on its own, roughly half a kilometre from the main island and reachable only by boat. The resort markets it as the world's largest overwater villa at about 1,700 square metres, with an infinity pool, a couples' spa pavilion with sauna and steam room, an air-conditioned gymnasium, a private cinema, a bar and a slide that delivers you straight into the lagoon.

Who it suits: the traveller for whom seclusion outranks square footage — nothing else on this list places you so far from a neighbour.

Honest note: the “world's largest” banner is the resort's own, and at 1,700 sqm it sits just shy of the St. Regis figure. The isolation that is the villa's glory also means every excursion, spa visit and dinner ashore begins with a boat ride.

Why it's here: set at the very end of the boardwalk in a UNESCO Biosphere Reserve, this residence trades a third bedroom for sheer breadth of deck. Anantara publishes it at 1,500 square metres (16,140 square feet), with each ensuite bedroom at opposite ends of the villa, an infinity pool perched over the reef, glass viewing panels for the turtles below, a private gym and an in-villa spa room. For a two-bedroom villa to rank this high on a size list is itself the story.

Who it suits: two couples, or a couple who simply want the most water and the fewest walls, with the resort's celebrated underwater restaurant a short walk away.

Honest note: with only two bedrooms it sleeps fewer than the larger estates above it, so the per-guest cost of all that space runs high.

Why it's here: the largest of Soneva Jani's celebrated overwater reserves, published at 1,421 square metres over two floors. It is the family entry on this list, with four bedrooms sleeping nine, a private gym, a steam and sauna room, a large kitchen and a retractable roof over the master bedroom for sleeping under the stars — and, of course, the curved slide that drops from the upper deck into the lagoon. Soneva's house style, all reclaimed timber and barefoot ceremony, lends the scale an unexpected warmth.

Who it suits: a family or two who want the most usable space rather than the single largest number, with the children's club and observatory a short cycle away.

Honest note: Soneva's own beachside Island Reserve runs larger still at 1,788 sqm — proof that the moment you allow dry land, the size record leaves the water entirely.

Why it's here: the Waldorf Astoria name has stood for the grand urban hotel for more than a century; in the Maldives the house translates that pedigree into a 1,113 sqm overwater residence, the largest in its villa range. Three bedrooms, two infinity pools, glass-floored dressing rooms over the reef and a dedicated concierge come with a complimentary private-yacht transfer on arrival — a quietly aristocratic touch in keeping with the marque.

Who it suits: a family that wants brand-name service and a spread across three islands of dining, with the villa as a calm overwater base.

Honest note: the resort's most famous overwater villa, the boat-access Stella Maris, has been withdrawn, so this three-bedroom is now the genuine top of the published range — do not book the older, larger figure you may still see quoted on third-party sites.

Why it's here: it earns its place not on pure floor area but on geometry no rival can match. The Muraka, Dhivehi for “coral,” is the world's first undersea residence: roughly 700 square metres above the water and a further 100 below it, its master bedroom set about five metres beneath the lagoon under a 180-degree acrylic dome. Opened in 2018, the rate includes a private chef, butler and boat. It is the only villa on this list where part of the house sits beneath the sea.

Who it suits: the once-in-a-lifetime occasion, where the experience of sleeping under the ocean outranks any tally of square metres.

Honest note: by floor area alone it is the smallest entry here; you are paying for the undersea suite, not for sheer size. Confirm the rate carefully, as it swings widely by season.
