Tucked behind a private bridge where the creek flows beneath a canopy of mature trees, 639 Hightree Road is one of two rare undeveloped lots in beloved Rustic Canyon available individually or together with neighboring 641 Hightree Road. Each sits off quiet Hightree Road, embraced by hillsides once home to a 1920s open-air amphitheater that echoed with poetry readings. In 1979, Ray Kappe envisioned a soaring mid-century masterpiece here plans approved but never built leaving today’s dreamer a remarkable blank canvas. Build ~5,000 sq ft on a single lot, or up to 10,800 sq ft across both. 641 offers 16,796 sq ft; 639 offers 16,184 sq ft32,981 sq ft total. A chance to create an enduring work of art in one of L.A.’s most storied settings.
