Welcome to The Cottle House, a mid-century modern masterpiece in Arapaho Hills. Originally designed by Bruce Sutherland and beautifully "retrovated" by Retrovations LLC, this home blends iconic 1960s style with modern-day comfort. A private atrium sets the tone, featuring custom walnut paneling, the original planter, and sculptural staircase. The dramatic roofline flows from the garage, over the atrium, and into the living space, where warm Douglas fir tongue-and-groove ceilings and refinished cork floors make a big statement. Floor-to-ceiling south-facing glass walls create a seamless indoor-outdoor vibe and flood the space with light. New energy-efficient aluminum and glass windows honor the original aesthetic while boosting performance. Custom cabinetry and wood paneling by Cream Modern give the kitchen and living areas a fresh yet timeless feel with colorful, yet modern Bespoke appliances, including an induction cooktop. The brick fireplace wall extends outdoors, connecting you to the patio, the best place for sunset cocktails and weekend hangs. The serene primary suite opens to the patio and features a stunning, newly designed ensuite. Head downstairs to the walkout basement with flagstone floors, a vintage Majestic fireplace, oversized flex space, and a bright office that makes work inspiring. Extras include a one-car garage with EV hookup, new AC and water heater, 40k in new windows, plus hidden storage for bikes and gear. Located in a 56-home MCM neighborhood eligible for the National Register of Historic Places - think historic tax credits and be part of the cool architecture club!
