Luxury homebuyers searching for a move-in-ready residence in the Florida Keys have a limited number of opportunities, especially within newly completed waterfront communities. Developed by Coral Gables-based Constellation Group in partnership with local Ironwood Venture Group, SeaGlass Cove is helping meet that demand with just 14 luxury residences overlooking the Atlantic Ocean in Marathon.
With homes starting at $3 million, the newly completed community pairs British West Indies-inspired architecture with contemporary coastal elements, private beach access and resort-inspired amenities in a location that has become increasingly attractive to both second-home buyers and investors. Throughout the community, an unusually high level of attention was given to the architecture, design and material selections, creating homes that feel far more custom than conventional developer product. That elevated level of design and finish is immediately apparent upon entering the residences and has become one of SeaGlass Cove’s defining characteristics.
Three of the currently available residences are fully furnished by D’Asign Source, the renowned Florida Keys architecture and interior design firm, while a fourth is now being delivered as the community’s model residence in collaboration with the world-renowned Interiors by Steven G., further expanding SeaGlass Cove’s turnkey offerings.
A Professionally Designed Oceanfront Residence
The furnished model residence spans more than 5,200 square feet of thoughtfully designed indoor and outdoor living space. Expansive walls of glass frame unobstructed Atlantic Ocean views while creating a seamless connection between the home’s interior and its waterfront setting.
The open-concept floor plan is designed for entertaining, with generous gathering spaces flowing onto oversized terraces that capture ocean breezes throughout the day. Contemporary finishes and refined materials create an elevated yet relaxed “barefoot-luxury” atmosphere inspired by the home’s coastal surrounding, while Interiors by Steven G. is bringing its signature design perspective to the model residence through a curated furnishings and interiors program.
The remaining homes are ready for immediate occupancy, eliminating the lengthy timelines often associated with furnishing and customizing a luxury waterfront property.
Private Beach Living with Resort Amenities
SeaGlass Cove delivers many of the amenities typically associated with a luxury resort while maintaining the privacy of a boutique residential community.
Residents enjoy access to a private white-sand beach, a resort-style pool overlooking the Atlantic Ocean and a pickleball court, along with other waterfront amenities designed to maximize the oceanfront lifestyle. Each residence also includes its own private cabana with ample space for entertaining family and guests. The intimate scale of the community allows homeowners to enjoy resort-caliber experiences without the crowds found at larger developments.
The combination of direct waterfront access, expansive views, resort-style amenities and carefully curated outdoor spaces creates an environment equally suited for quiet relaxation or social gatherings and entertaining.
Weekly Rental Flexibility Adds Investment Appeal
One of SeaGlass Cove’s distinguishing features is its allowance for weekly rentals, offering owners flexibility that is difficult to find among luxury residential communities in the Keys.
That opportunity appeals not only to buyers seeking a second home but also to those interested in generating income when they are away. As luxury travelers increasingly seek spacious, private accommodations rather than traditional resorts, professionally designed turnkey residences have become particularly attractive within the vacation rental market.
For buyers, the ability to enjoy the home personally while maintaining rental flexibility adds another layer of value beyond the waterfront location itself.
Marathon Emerges as a Luxury Destination
While Key West and Islamorada have long dominated conversations about luxury real estate in the Florida Keys, Marathon and the surrounding Middle Keys are experiencing growing interest from affluent buyers looking for a more relaxed waterfront lifestyle.
Improved amenities, new luxury developments and increased demand for private coastal retreats have helped elevate Marathon’s profile over the past several years. Buyers are discovering that the area offers many of the experiences associated with the Upper and Lower Keys while maintaining a quieter atmosphere and convenient access to boating, fishing, diving and waterfront recreation.
Communities like SeaGlass Cove reflect this evolution, introducing a higher level of residential design and amenities that appeal to today’s luxury buyers.
With only 14 residences and a limited number of homes remaining, SeaGlass Cove represents one of the few opportunities to purchase a newly completed oceanfront residence in Marathon that combines designer interiors, private beach access, resort-style amenities and flexible ownership options. As the Middle Keys continue attracting luxury buyers from around the country, opportunities like this are becoming increasingly scarce.
