Tucked at the end of a quiet cul-de-sac near Chautauqua Park, 705 Willowbrook is a rare architectural treasure in one of Boulder’s most sought-after enclaves. Originally designed by Hobart “Hobie” Wagener in 1957 and expanded in the late 1960s by celebrated architect Tish Papachristou, the home is a stunning example of mid-century vision integrated with its natural surroundings.

A bridge over a serene stream leads you to custom double wood doors and into the heart of the home. Just to the right, the main-level family room makes a dramatic impression with soaring wood-paneled ceilings, tall windows that invite in the landscape, warm parquet floors, and a wood-burning stove. Built-in cabinetry includes a wet bar, a hibachi grill, and a custom corner seating area—offering a one-of-a-kind space for entertaining or relaxing. To the left of the entry, the spacious living room features beamed ceilings, floor-to-ceiling windows, and another wood-burning fireplace. The adjoining dining room is wrapped in glass, with views of lush greenery all around, and connects directly to a classic kitchen defined by walnut cabinetry, a pantry, bookshelves, and vintage tile flooring. A powder room completes the main level.

Upstairs, the Papachristou-designed addition forms a private and light-filled retreat. A wood-railed landing overlooks the family room below and leads to an office with built-in bookshelves, pine flooring, and wood-beamed ceilings. The primary suite is spacious and serene, featuring a private balcony, reading nook, window seat, and multiple closets—including a walk-in with built-in vanity and shelving. A window framing the first Flatiron offers a daily reminder of Boulder’s natural beauty just beyond. The en-suite bathroom and treehouse-like feel make this space truly special.

The lower level offers incredible space for guests or long-term stays, with three bedrooms and two bathrooms. One of the bedrooms opens directly to the outdoors through sliding glass doors, blending indoor comfort with the home’s serene natural setting. A large family room with a fireplace creates a secondary living space, while a wine cellar, expansive laundry area, and ample storage add everyday functionality. Additional features include a two-car garage, a large sunny studio tucked beneath the primary suite—ideal for creative or functional use—and an adjacent storage area that makes space for everything you need.

Set on a beautifully landscaped lot, the outdoor spaces are just as captivating as the interiors. A large wrap-around deck, main-level curved patio with built-in seating, and meandering walkways create quiet moments of connection with nature. A spiral staircase offers an alternate entrance to the main level, while the stream, mature trees, and thoughtful plantings add a sense of privacy and tranquility that’s rare to find so close to Boulder’s best trails, open space, and the historic Chautauqua Dining Hall and Auditorium.

With just three owners since it was built, this home holds a special draw–rich with architecture, intimate with nature, and ready to embrace the next people who call it home.
