Positioned on the white sands of Siesta Key, 8250 Sanderling Road is more than a residence; it is a bold statement in modern architecture, masterfully envisioned by renowned architect Guy Peterson, FAIA. Set on 1.54 private acres with 150 feet of Gulf-front beach and 150 feet of lagoon frontage behind the gates of the exclusive Sanderling Club, this estate is a rare fusion of design innovation, artistic expression, and coastal tranquility. Widely recognized as one of Florida’s most iconic modern beach residences, the property has received top honors including the AIA Florida Test of Time Design Award, AIA Florida Gulf Coast Honor Award and the AIA Florida Excellence in Architecture Award, and has been featured in The Wall Street Journal, HGTV’s Homes Across America, Robb Report, Florida Design, Sarasota Magazine and more. It is also prominently included in Four Florida Moderns and 50 US Architects Residential and Planning, placing it among the most significant architectural achievements in the country. The home was designed as a series of four interconnected pavilions anchored in concrete and glass. It was reimagined in 2014 by the original architect, Guy Peterson, alongside Michael K. Walker and Richard Geary. The result is a striking architectural clarity that elevates the original design while introducing refined modern comforts. The sculptural façade is defined by bold horizontal lines, artful cutouts, and a seamless blend of poured concrete, steel, and sanded glass. A shell stone path leads to a dramatic entry, where the residence begins to unfold like a gallery of light and form. Inside, the interiors echo the clean geometry of the exterior. A soaring multi-level foyer acts as a central spine of the home, where light, shadow and structure interplay like a living installation. The custom-designed bar, lit by an onyx countertop, is functional and atmospheric. The dining room is framed by concrete columns and translucent glass, revealing a cinematic view of the Gulf beyond. The kitchen, anchored by warm teak millwork, features dual islands, Miele and Wolf appliances, and honed marble surfaces, creating a space as elegant as it is functional. The owner’s suite offers a peaceful retreat with a sitting area, private terrace, and coffee bar, while dual baths evoke spa-like tranquility with stone finishes and minimalist detailing. A private office with panoramic Gulf views inspires focus, while additional guest suites offer comfort and privacy with en-suite accommodations. Outside, a sprawling terrace connects indoor and outdoor living, ideal for intimate reflection or entertaining against the sound of waves. Residents of The Sanderling Club enjoy access to a private marina and beach plus 24-hour guard-gated enclave celebrated for its discretion and architectural legacy. With its distinguished pedigree and timeless design, 8250 Sanderling Road is a coastal sanctuary that honors the past, elevates the present, and secures its place among the most architecturally significant homes in on Florida’s Gulf Coast.
