Along the serene edge of Maria Sanchez Lake lies one of downtown St. Augustine’s most alluring hidden treasures. Beyond a graceful brick archway, this private sanctuary reveals itself — a home so captivating that every guest departs inspired and eager to return.
A study in balance and beauty, the residence blends European refinement with a soulful, worldly aesthetic. Its design nods to the understated elegance of Belgian estates, the timeless sensibility of Darryl Carter, and the calm minimalism found in Asian influence. Every surface and texture — from ancient Burmese teak and reclaimed oak to artisan brickwork — was chosen with intention, creating an enduring home rooted in craftsmanship and character. The main level was envisioned for effortless entertaining and connection. Folding glass walls blur the line between indoors and out, opening completely to the front courtyard and rear lake terrace. A masterfully built summer kitchen by a local craftsman anchors the courtyard beside a peaceful plunge pool and spa-style bath. Inside, the chef’s kitchen delights with a statement Viking range, open shelving, and dramatic marble slabs that extend seamlessly up the walls. Generous dining and living areas flow naturally toward the lakefront, where gentle breezes and daily scenes of herons and egrets create a living masterpiece.
Originally a 1920s cottage, the home’s historic essence now mingles with bold modern lines. Just off the main living area, a refined study framed by an antique arched window captures glimmering lake reflections and sunlight by day, and candlelit warmth by night.
Upstairs, the lake becomes your morning view. The primary suite and an adjoining guest suite  currently used as a sitting retreat  each open to private balconies beneath a graceful old tree. Both baths are finished in marble with curated lighting and high-end fixtures. Along the south side, a screened porch invites lingering conversation or afternoon reading and transitions beautifully to a sunlit terrace ideal for herbs or climbing roses.
“The Little Nest,” a third-floor hideaway, crowns the home with panoramic vistas that stretch across the historic skyline to the Intracoastal. Vaulted ceilings, reclaimed beams, and marble accents create an inspiring space for writing, resting, or simply dreaming.
Across the brick courtyard, the detached garden studio offers a charming bonus retreat  with its own entrance, vaulted ceilings, reclaimed-beam details, and a small kitchenette and bath. Originally permitted as a shed and not counted in the home’s total living area, this stylish escape offers flexibility for guests, creative work, or quiet reflection.
Timeless, tactile, and transporting  153 Washington Street is more than a residence. It’s a rare experience of historic St. Augustine living, where cobblestone streets and shimmering waterways frame a lifestyle that feels both centuries old and utterly new.
