About This Property

Rarely does a property come to market with a story this layered. Harper's Topiary Garden at 3547 Union St is a Mission Hills landmark. A 1939 single family home with a 1914 casita, set on 13,142 sq ft of terraced grounds featuring a decades-old topiary garden tended by the same family for generations. Featured in San Diego Magazine, Hidden San Diego, and viral across social media, this is one of San Diego's most beloved private spaces. The garden's legacy includes a dedicated caretaker whose knowledge of these grounds spans decades. Step through the gate and discover a secret garden world sculpted topiaries cascading down the hillside, a tranquil koi pond, a shimmering pool, and sweeping ocean and bay views that stretch to Point Loma, Coronado and beyond. The main house offers 2 bed/1 bath with hardwood floors and a finished basement. The detached casita at 3549 Union St adds 2 bed/1 bath and 1,084 sq ft with its own address. Detached 2-car garage. A property for the buyer who understands that certain things cannot be built, only inherited.
