One Causeway, Three Water Sides
Brickell Key is an artificial island off downtown Miami. A single causeway carries every arrival and every departure. The Mandarin Oriental Hotel and Residences sits at 750 Claughton Island Drive, and the site faces water in three directions.
Floridian Development published the construction report on 2 September 2026.
The Hotel Side Holds 121 Rooms
The north tower rises 33 stories to 426 feet. It carries 121 hotel rooms, 66 residences and 28 hotel-branded residences. The south tower rises 66 stories to 850 feet and holds 228 homes. Kohn Pedersen Fox designed both.
The report counts the scheme at 294 units and 149 keys. The 294 units are the 228 homes and the 66 residences. The 149 keys are the 121 rooms and the 28 branded residences. The issued master building permit puts the build at $226 million and 1,286,326 square feet.
The Calendar an Itinerary Clears
Deep soil mixing began in September 2026. Groundbreaking is planned for October 2026. The towers start rising in 2027. Construction is expected to conclude in 2030.
No source names a month or a season for the first arrival date. A tour operator cannot book this property for the coming seasons. Clients routed through Brickell before 2030 stay on the mainland.
Distances a Day Plan Can Use
Straight-line distances from the Claughton Island Drive site: the Metromover station 766 metres, Brickell City Centre 856 metres, Mary Brickell Village 901 metres, Bayfront Park 1,164 metres, Miami International Airport 10,738 metres.
The causeway adds to each figure. No document in the set carries a walking time, a shuttle or a water-taxi landing.
A Half Day on Foot
Cross the causeway first. Run the shopping and dining block at Brickell City Centre, then take the Metromover into the downtown loop. Bayfront Park takes the late afternoon. The return leg is the causeway again.
That sequence holds for a client based downtown. A client on Miami Beach adds a separate transfer.
What the Island Lost
The island held 326 hotel rooms from 2000. Swire Properties closed the hotel in 2025. The building came down in a controlled implosion on Sunday 12 April 2026 at 8:30 a.m., and CBS News Miami covered the demolition. Road closures and an exclusion zone covered Brickell Key that morning.
The rebuilt house runs 121 rooms. A coach operator that sold the old property sold 326 rooms and will sell 121.
The Amenity Stack
The report lists outdoor spaces with views, pools, private waterfront cabanas, sports courts, a spa, a wellness deck and resident lounges. It names no restaurant, no bar and no spa operator. It publishes no suite count inside the 121 rooms, no room categories and no rate.
Commercial square footage and parking counts have not gone to public boards. Water access stays open as a question, because the site faces water on three sides and no document describes a marina berth, a beach or a boat landing.
What the Client File Carries Before 2030
Write the address, the 121-room count, the 2030 completion window and the causeway approach. Put the two towers in by height. Leave the rate blank until a sales office publishes one.
Then date the file. A 2030 opening puts this property in a forward plan, and the coming seasons run on the mainland.
