The Collins-Wellington Estate | Spanish-Revival Masterpiece on 8 Private Acres – Mills Act Designated Step into timeless grandeur at the Collins-Wellington Estate, a one-of-a-kind Spanish-Revival castle nestled atop 8 secluded acres in the heart of San Diego. This historic 1928 architectural marvel was envisioned by H.A. Collins and later cherished by the prestigious Wellington family—famed for hosting soirées attended by Southern California’s elite. A gated, tree-lined drive welcomes you with a quarter-mile of privacy and anticipation, leading to a majestic 5,766 sq ft residence rich in heritage and soul. Listed on the Historic Register and benefitting from significant tax savings under the Mills Act, this estate is truly a legacy property. Inside, every corner tells a story—original peg-and-bowtie curly oak floors, hand-painted ceiling designs, inlaid onyx flooring, and soaring 18-foot cathedral ceilings blend seamlessly with the intricate wrought iron and arched motifs that define authentic Spanish architecture. Enter through a regal double-height stone foyer with gilded detailing and a stunning wrought-iron staircase lined with hand-painted Spanish tiles. The 35’ x 25’ grand ballroom—once alive with the sounds of live musicians serenading from the balcony above—is a crown jewel of old-world glamour. The estate offers four expansive bedrooms, each with en-suite baths and space for additional sitting areas or home offices. A charming upstairs loft overlooks the ballroom and can function beautifully as a study or fifth bedroom. Highlights Include: - Iconic 1928 Spanish-Revival architecture - 8 acres of gated, private land - 5,766 sq ft of luxurious living space - Grand ballroom with cathedral ceiling & balcony - Historic designation with Mills Act tax benefits - Curly oak floors, inlaid onyx, artisan tilework, and hand-painted ceilings - Architectural details rarely found in modern construction - Ideal for entertainers, history lovers, or legacy homeowners Rarely does such a majestic estate become available.
