PB hotel design editorial

Planted on a five-acre peninsula where the Atlantic meets the Gulf of Mexico in Marathon, Florida, Isla Bella Beach Resort arrived in 2018 as a rare attempt to give the Middle Keys a resort of genuine architectural ambition. The low-rise buildings draw on the vernacular of traditional Florida coastal construction — white-painted clapboard cladding, deep wraparound verandas stacked across three floors, X-pattern balustrade panels, and cedar-toned deck stairs stepping directly onto the sand — producing a massing that suggests a well-established fishing community rather than a purpose-built resort. Blue-painted window surrounds and louvred details tie the exterior palette to the water on both sides. Inside, the interiors strike a balance between crisp resort white and the saturated blues of the surrounding sea. Rooms are furnished with lacquered white case pieces, silver-glazed ceramic lamps, and deep navy geometric carpet, while floor-to-ceiling curtains in a bold indigo palm-tree print — a pattern that recurs across roman blinds and scatter cushions — carry a confident tropical personality without tipping into kitsch. The pool pavilion, capped with a ribbed pyramidal roof, sets wicker chaise longues in geometric-patterned cushions against limestone-toned pool decking, blue-and-white striped umbrellas completing the nautical register. The waterfront restaurant opens its walls entirely to the bay, rattan armchairs and encaustic-patterned floor tiles grounding the dining room in a vernacular that feels closer to the Florida Keys' own material culture than to generic resort hospitality.

"Best resort we've been to in years. Family friendly, great rooms with balconies and fantastic views of the Gulf!, Multiple pools, great beaches, activities for kids. Mahina restaurant was awesome.. Great place to relax and secluded from the hustle and bustle of the world. Relatively new and no expense was spared when this resort was designed and constructed. Don't miss the opportunity to enjoy this island like experience!"

"Check in was great. Very informative and welcoming. Our 2 bedroom first level was what I expected stepping out on the white sand and great view. The Mahina Restuarant was great. The service from Garth, Lamont & all the staff couldn't have been better. I'm a Foodie and Wine lover and was great. I would have liked another chicken breast choice is my only small comment which is pretty impressive. I think they could do away with the giant Chess board as it was mostly kids throwing the chess pieces around. I wish parents were more respectful and watched their kids better. A Bocce ball court seems to make more sense for the setting. Just my 2 cents. I would highly recommend this Resort."
