On one of Avondale's most admired streets, this extraordinary St Johns Avenue estate stands as a true expression of luxury living in a historic setting. Featured in Jacksonville's Architectural Heritage, this remarkable residence is recognized as a prominent landmark and a celebrated example of Mediterranean Revival design. Designed by architect Jefferson D. Powell shortly after his return from Venice, the home draws direct inspiration from the palaces lining Italy's Grand Canal and was originally built for Max Knauer, a prominent Jacksonville hardware dealer. Just moments from the Shoppes of Avondale, it commands attention with architectural distinction, presence, and a sense of arrival that feels both grand and deeply rooted in place. The Venetian influence is unmistakable. The projecting two story entrance pavilion features a dramatic ogee arch and a star wheel motif inspired by the Palazzo Contarini Fasan. Arched windows of varying forms, columns, stylized leaded glass, brick and cast stone ornamentation, and crenelated parapets define the exterior. Even the chimneys are adorned with arched openings, all beneath a mission tile roof that completes the authentic Mediterranean profile. This is architecture with intention, artistry, and lasting significance. The main residence offers four bedrooms, a dedicated office, two full baths upstairs, and a gracious powder room on the main level. A finished basement provides additional living space with an additional bedroom and a full bathroom, ideal for guests or extended stays. Connected by a covered walkway, the private casita apartment includes its own full bath and thoughtful upgrades, creating a refined retreat that feels both separate and seamlessly integrated. Inside, every space reflects the careful stewardship of the current owners. The kitchen anchors the home with Sub Zero refrigeration, Wolf double ovens and a six burner gas range, Fisher and Paykel dishwasher, a built in pantry, and elevated finishes that balance performance with quiet elegance. Lighting has been curated throughout, systems thoughtfully enhanced, and modern functionality introduced with respect for the home's architectural integrity. Outdoors, the property unfolds into a private resort setting. The grounds have been completely reimagined with professional landscaping, extensive landscape lighting, upgraded drainage, and a reengineered irrigation system that keeps the property pristine year round. A striking pool and spa serve as the centerpiece, complemented by a custom summer kitchen, paver entertaining areas, and a natural gas fire pit. Integrated audio, app controlled pool features, and seamless indoor outdoor flow create an environment designed for both grand entertaining and everyday enjoyment. Behind the scenes, the home is equally impressive. Newer air conditioning systems, upgraded electrical, a dedicated communications closet, enhanced security, a water softener, and meticulously maintained roof and mechanicals reflect a level of care rarely seen. Improvements were completed by respected local professionals, reinforcing confidence in both the beauty and performance of the home. Celebrated in Jacksonville Magazine and featured on the RAP Home Tour, this is not simply a luxury home in Avondale. It is a landmark residence of architectural importance, thoughtfully elevated for modern living while honoring the character and craftsmanship that make it truly irreplaceable. A genuine jewel on St Johns Avenue, ready for its next steward.
