A remarkable opportunity to build a fully realized 2,826 sqft architectural masterpiece envisioned by principal architect Semone Kessler, AIA RA of Matter Studio. Perfectly sited in romantic Castellammare on an unbelievable ocean-facing parcel directly above the coastline, where you can hear the waves, watch whitewater dissolve into endless blue horizons, and feel the ocean mist from your future living spaces. This offering includes beautifully developed plans for a three-bed five-bath two-level Spanish-inspired modern residence, complete with interior architecture and design. The main level features a luxurious primary suite, vaulted and beamed ceilings, sculptural stonework, and expansive glass walls that open to a private courtyard, ocean-view terraces, and sweeping coastal breezes. The design blends the romance of old California with refined modern detail, creating a serene, light-filled residence conceived to feel as though you are floating above the sea. Just beyond the property, the historic footbridge provides beach access, offering an effortless connection to the sand and shoreline. Significant preliminary work has already been completed, including a favorable professional geologic report and key early planning steps, saving significant time and uncertainty. This is an extraordinary opportunity to realize a signature Matter Studio home in one of the world's most coveted seaside enclaves, where architecture, landscape, and the rhythm of the ocean come together in perfect harmony. And the sunsets are other-worldly.
