Seven kilometres is the number to hold on to. That is the length of unbroken white-sand beach attached to the El Cuyo Estate, a 140-hectare peninsula on the northern edge of the Yucatán, listed through Beauchamp Estates at US $115 million (£86.66 million).
Contiguous private shoreline at that scale has effectively stopped existing in the Gulf basin. The Riviera Maya was parcelled decades ago; what remains trades in hundreds of metres, not kilometres. El Cuyo is the exception because it sits somewhere nobody was allowed to build.

What is being sold, precisely, is land and permission. There is no palace on this site, but here is a masterplan, a set of designs, and – per the vendors – and consent to execute either of two schemes: a 64-villa residential resort with a 40-suite hotel, projected at $530 million gross development value (GDV), or a single private domain of up to 340,000 square feet, projected at $345 million.
Both figures describe what a buyer might spend and recover. The $115m is the only number currently attached to an asset.
The an island-style site of ecologic significance
El Cuyo lies at the eastern end of Yucatán state, roughly two and a half hours from Cancún by road and considerably less by air or water. The estate occupies an island-style peninsula: Caribbean on one flank, and on the other the lagoons and wetlands of the Ría Lagartos Biosphere Reserve. That reserve is not incidental scenery.
It covers 60,348 hectares, holds UNESCO Man and the Biosphere designation, was listed under the Ramsar Convention in 1986, and is the only nesting site for the Caribbean flamingo. Some 20,000 birds arrive annually.

Nearby, the Las Coloradas lagoons run bubblegum pink – a genuine effect of halophilic microorganisms and brine shrimp, occurring in what are also working salt-evaporation ponds. The photographs are real. The wilderness framing is partial.
For context on the asking price: the previous benchmark for Mexico was El Cielo 2, a 2.43-acre oceanfront homesite at Maravilla, Los Cabos, listed at $90m in 2022. El Cuyo clears it by $25m and does so on 142 times the land.
A costal estate with potential $345m GDV
The designs are by Casa E Progetti, the London super-prime design house whose hotel work includes schemes for InterContinental and Sheraton.
The resort scheme divides the peninsula into 64 beachfront villas, each with 100 metres of private shore and plots running from one to 2.8 hectares. Each villa reaches 5,000 sqaure feet across three floors: reception rooms and a flexible fifth suite at ground level, four VIP suites above, a vaulted top floor for a playroom or teenage lounge.
The architecture is the most interesting thing in the file. Casa E Progetti has worked in Mayan vernacular – oblong and apsidal footprints, pole-and-frame construction, stone feature walls, pitched palm thatch.
The rounded ends are not decorative; Apsidal plans shed hurricane-force wind rather than presenting it a flat face, and steep thatch sheds rain fast. Open-air layouts and vaulted roofs handle the cooling. This is one of the few super-prime schemes where the heritage reference and the engineering brief have endured from the same document.
The hotel at the centre takes its cue from Palenque, and specifically the palace complex of K’inich Janaab Pakal, who ruled there from 615 to 683. Linked great houses, central atriums, grand courtyards, the whole under a single vast thatched roofscape, with lodges arranged in the grounds as Pakal’s were. Interiors run to stone columns, beam ceilings, murals, and bespoke joinery.

For a single owner, that hotel becomes the palace: 40 bedrooms, two kitchens including a professional one, library, cinema, gym, salon, and indoor and outdoor pools, with the lodges converted to guest accommodation, family office, staff, and security. Arrival is by yacht, helicopter, or private aircraft – the estate has a jetty and land designated for a helipad and runway.
Beauchamp’s own framing is Mustique. Gary Hersham, the firm’s founding director, describes a trophy estate suited to “a Mustique style residential resort of luxury beachfront villas on generously sized landscaped plots, or for a billionaire to own a private palace estate.”
The terms and conditions to factor in
Mexican coastal ownership carries structural conditions that no masterplan removes, and a buyer at this level should have them priced before viewing.
Foreign nationals cannot hold direct title within 50km of the coast. Ownership is routed through a fideicomiso – a renewable bank trust – or a Mexican corporation. This is standard, well-trodden, and non-negotiable.
The 20-metre strip above the high-tide line is federal maritime-terrestrial zone. It is held by concession, not owned. Seven kilometres of beach is exclusive in practice and public in law.

Consent itself is layered. Mexican development approval runs through municipal land use, state authorisation, and a separate federal environmental process administered by SEMARNAT. Any buyer should establish which of those are in hand and how they are dated.
The reason to be precise about this is that enforcement in Ría Lagartos is live. In mid-2026, PROFEPA and CONANP closed five sites across the Celestún and Ría Lagartos reserves for environmental damage, part of a wider peninsula-wide programme covering thousands of hectares.
Investor notes: who are the buyers?
Beauchamp put demand for luxury Mexican beachfront with buyers from the United States, Canada, Mexico City, and Monterrey, with a smaller cohort from the UK and Western Europe. Purchasers skew towards families in their thirties and forties and early-retiring American baby boomers, increasingly supported by US lenders now writing mortgages on Mexican residential stock.
On the resort economics, Kay Louise Smith, super-prime sales broker at Beauchamp, states a model returning at least 2.5 times capital invested, with villas achieving over $2 million per unit against local comparables of around $4,400 per square metre.
The palace may be a drawing but resort remains line items on a spreadsheet. What is actually for sale is seven kilometres of Caribbean coastline that exists in this condition because it was protected, held for three decades, and never subdivided.
