This tranquil, picturesque, mostly level, one-acre property nestled at the entrance to one of Marin County's most beloved trailheads at Baltimore Canyon Open Space Preserve was designed by award-winning, mid-century modern architect, Ian MacKinlay. Known for using glass to create wide open vistas that blur the distinction between inside and out, this home features towering walls of south-facing glass imbuing the residence with an ethereal quality as if suspended amidst the surrounding forest. The original owners, pioneering outdoor enthusiasts, esteemed for their pivotal role in preserving the Marin Headlands from development, selected this location to build their family home due to its proximity to open space. While the home retains much of its original character and charm the recently updated kitchen/great room is modern, bright and chic with quartz counters, s/s appliances, hardwood floors and an adjacent laundry room. Designed for indoor/outdoor living the kitchen opens directly to the expansive backyard, a private and serene wonder with level lawns, a pool, garden beds and outdoor dining and gathering areas. Now, more than 60 years later, this magical property is available.
