About This Home
Presenting the iconic Collins-Wellington Estate, a historic Spanish Revival masterpiece originally built in 1928 by visionary H.A. Collins and gracefully set atop approximately 8 secluded acres in the heart of National City. Rich in architectural significance and timeless elegance, this extraordinary Mills Act-designated estate offers a rare opportunity to own one of San Diego County’s most treasured legacy properties. A gated, tree-lined drive creates a dramatic approach to the stunning 5,766 sq ft residence featuring 5 bedrooms, 4 baths, and remarkable old-world craftsmanship throughout. Inspired by authentic Spanish castle architecture, the home showcases soaring 18-foot cathedral ceilings, hand-painted beam ceilings, original peg-and-groove hardwood floors, intricate wrought-iron details, imported Spanish tile, repeating arches, and rare inlaid onyx accents rarely seen today. Designed for both grand-scale entertaining and luxurious living, the estate offers expansive formal rooms, a dramatic ballroom, multiple fireplaces, and an upstairs loft overlooking the impressive main living area—ideal for a home office, library, studio, or retreat space. Every detail reflects the artistry and craftsmanship of a bygone era while offering the scale and privacy desired for modern estate living. The sprawling grounds provide exceptional privacy, mature landscaping, and endless possibilities for multigenerational living, luxury entertaining, boutique hospitality, or creative retreat use. Conveniently located near downtown San Diego, waterfront attractions, shopping, dining, and major freeways while offering the charm and prestige of a private historic estate. Mills Act designation may provide significant property tax savings for qualified buyers. A truly once-in-a-generation offering where history, architecture, and opportunity converge.
