Perched among the treetops of coveted Northwest Hills, this meticulously preserved mid-century modern residence delivers the clean lines, honest materials, and indoor-outdoor connection that define the genre at its best. Vaulted beam ceilings, floor-to-ceiling glass, and clerestory windows throughout draw the tree canopy in from every angle, while a commanding native limestone fireplace anchors the expansive living space. Flagstone flooring runs continuously through the entry, kitchen, den, and dining areas - grounding the interior with texture and warmth - as hardwood takes over in the living room. The kitchen is thoughtfully outfitted with walnut cabinetry, a substantial center island with built-in oven and microwave, professional stainless appliances, and open shelving, flowing naturally into the den and media area without interruption. Stone walls and vaulted beam ceilings carry through both spaces, maintaining the home's architectural integrity at every turn. A private courtyard patio brings the outdoors in and extends the living space beyond the walls. The lower level offers an additional conditioned studio and storage space accessible via a private exterior entrance on the north end of the property - ideal for a workshop, creative studio, or expanded storage. Spanning 3,000 square feet across 4 bedrooms and 2.5 baths on a prime corner lot measuring nearly half an acre (.485 acres), this is a substantive home with genuine architectural character - a rare opportunity to own a true piece of Austin modernist history. Zoned to Highland Park Elementary, Lamar Middle, and McCallum High School.
