Casa Alta presents an extraordinary opportunity to own two separate, side-by-side ocean view parcels in the heart of Olde Del Mar, totaling just over half an acre. One parcel houses a brand-new custom 4,725 sq ft residence of exceptional architectural caliber, while the adjoining north lot offers remarkable flexibility for a future second home + ADU, sport court, expanded grounds, or other complementary use - creating the perfect family compound! The new residence itself is a testament to patience, precision, and an unwavering commitment to architectural excellence. In a landscape as protected and storied as Olde Del Mar, a home of this caliber, conceived by renowned local architect Brian Church and constructed by Joshua Herbst, represents a rare achievement that transcends the typical luxury build. Perched above the village on a private, lushly wooded parcel, Casa Alta enjoys beautiful panoramic views of the Pacific while maintaining an exceptional sense of seclusion. The setting evokes a sophisticated coastal tree house, where sweeping ocean vistas are framed by mature heritage trees and the natural surroundings create a timeless sense of place reminiscent of Montecito or Pebble Beach. With endless opportunities on the north lot, this double parcel property presents a rare invitation to invest in the best part of town! Designed for elevated coastal living, the home features five bedrooms, multiple covered decks, a private office, elevator access to all levels, and the latest smart-home technology. Outdoor amenities include a stunning lap pool, outdoor kitchen, fire pit, dedicated pool bathroom, turf lawn, lush landscaping, citrus trees, and multiple spaces for entertaining and relaxation. Every material and finish has been thoughtfully curated, with interiors designed by John McCulley, known for his refined coastal-modern aesthetic. The result is a residence that feels sophisticated yet effortless, with exceptional attention to detail throughout. Perfectly positioned in the hills of Olde Del Mar, the property is within walking distance to the beach, village restaurants, boutiques, and attractions while sitting above the activity below. The combination of panoramic ocean views, brand-new custom construction, more than half an acre across two separate parcels, and the extraordinary potential of the adjoining north lot creates an offering rarely available in one of San Diego’s most coveted coastal communities. Do not miss this exceptional opportunity to own a newly completed architectural residence together with a valuable neighboring parcel in one of Del Mar’s most desirable settings.
