SAN DIEGO (FOX 5/KUSI) -- “This house was intentionally built like a superyacht with luxurious marine-grade materials," said global real estate advisor Rande Turner. "The goal is to spend your time using it, not maintaining it.” He's talking about an oceanfront estate in Del Mar that is now on the market. It's the most expensive listing in the city as of November 2024, with a $75 million price tag. The 30,491-square-feet abode sits on a rare beach lot located at 2920 Camino Del Mar.

For instance, it has a DaVinci Shake roof and a seawall to safeguard the property.

It boasts a main house, two guest houses, as well as a space for "privacy, family connection and relaxation," the real estate advisor explained. “Ocean House is about lifestyle per square foot. You have this flexibility as a gathering place to activate the beach lifestyle, and then privately retreat from it," said Turner. "The house is a true expression of quiet luxury and the quest for anonymity.” The estate was designed as indoor/outdoor retreat space. It has 75-foot beachfront deck, a pool and spa, along with an expansive lawn that offers space for gatherings. There's also an interior courtyard that includes a ping-pong pavilion, grill area and fire pit against a backdrop of ocean views. Ocean House Del Mar is one of 83 oceanfront properties along the city's pristine stretch of coastline. It was originally acquired by a California family in the 1930s and now stands as one of the last oceanfront estates in the area. “This property is one of one. It took over 12 years from concept to completion and current replacement cost is aligned with the list price if one ventured down this path today," Turner continued. "We are extremely confident in the depth and demand of the North County coastal market in 2025. Ocean House is a legacy property; once sold it may not be available for generations to come.”
