A stunning mid-century modern home at 617 Grizzly Peak Boulevard in Berkeley has hit the market, representing the finest example of post-war residential design that emphasizes openness, simplicity, and harmony with the natural environment. The property, known as the Colbie House, captures the essence of mid-century architecture while seamlessly integrating modern upgrades that enhance both sustainability and livability. The home will be featured in a Twilight Tour co-hosted with BAHA on Friday, October 3, from 4:30-6:30 p.m., followed by open houses on Saturday and Sunday, October 4-5, from 2-4 p.m.

"This home is a wonderful example of how thoughtful renovations can preserve the spirit of the original design while making it even more livable for modern families," said Megan Micco, the listing agent with Compass. "It's rare to find a property that maintains its mid-century character and also delivers the level of care this home has received."

Built in 1953 by architect Morgan Shaw for Dr. and Mrs. K.S. Colby, the house represents a significant piece of Berkeley's architectural legacy. Shaw was among several Bay Area architects who, during the post-war building boom, embraced a forward-thinking vision for residential design featuring seamless indoor-outdoor flow, expansive windows, and warm natural materials. The home showcases walls of glass that display sweeping views of San Francisco Bay, stretching from Marin County to San Francisco and down the Peninsula. Much of the interior features redwood paneling with clean, minimalist lines that define the mid-century aesthetic.

Over the decades, enhancements by renowned architects Bill Glass and Bennett Christopherson have brought new depth to Shaw's original vision while remaining faithful to its timeless design principles. "From the moment you walk in, you can tell this home was designed to celebrate light and landscape," Micco explained. "The views are simply breathtaking, and the flow between the indoor and outdoor spaces makes it feel incredibly tranquil."

The most significant transformation occurred in 2016 when the kitchen, bar, and dining area underwent a complete reimagining by designer Mason St. Peter, whose work has been featured in Abode magazine. The resulting chef's kitchen honors the home's mid-century aesthetic while offering state-of-the-art features for contemporary living. Throughout the home, custom millwork was meticulously crafted by renowned woodworker Nobuto Suga of Small Works, whose exceptional attention to detail elevates every room. A vintage Poul Cadovius wall unit serves as both a striking design centerpiece and versatile display space for books, records, and art.

Additional renovations included a complete remodel of the lower-level bathroom and the addition of a custom solid oak dressing room to the primary suite. Updated LED lighting was installed throughout the home, significantly improving both energy efficiency and ambiance. The front windows were replaced with double-pane, low-E glass to enhance insulation, and a life-extending protective roof coating was applied to ensure long-term durability.

"The sellers approached these renovations with incredible care," Micco noted. "Every decision was made to enhance the home's livability without sacrificing its original architectural integrity."

Sustainability has become a guiding theme in the evolution of this remarkable property. The home features a comprehensive solar energy system that provides clean, renewable power while reducing environmental impact. The electrical system was completely overhauled and upgraded to 200 amps to support modern energy needs. Dual Tesla Powerwalls were installed for energy storage and grid resilience, while a 240V electric vehicle charger was added to the garage for convenient EV charging.

Even the entertainment system was designed with intentional discretion – a hidden projector and retractable screen disappear seamlessly into the living space when not in use, preserving the home's clean, minimalist aesthetic that defines mid-century design.

In 2020, the backyard underwent a complete transformation under the expert direction of landscape designer Heather Reid. The comprehensive redesign includes a custom Ipe hardwood deck, new stairs and entry gate, retaining walls, raised planters, and a sophisticated four-zone irrigation system designed to improve water-use efficiency. The outdoor living space is anchored by a Galanter & Jones heated bench and a plumbed Lumacast fire pit, creating an inviting atmosphere for year-round enjoyment.

The mature landscaping features a stunning Japanese maple tree, various fruit trees, and a well-maintained vegetable garden that adds seasonal variety and natural beauty. The home's exterior was recently repainted by Arana Painting, ensuring a fresh and polished appearance that complements the architectural integrity.

"Outdoor spaces are so important here in Berkeley, where we enjoy mild weather most of the year," Micco emphasized. "The backyard at 617 Grizzly Peak feels like a private sanctuary, perfect for quiet mornings or lively gatherings with friends."

Beyond its exceptional design and premium features, the home's prime location near Tilden Regional Park significantly adds to its appeal. Situated atop the Berkeley Hills, the Colbie House offers a peaceful retreat surrounded by nature while maintaining convenient access to UC Berkeley and the vibrant shopping and dining districts of North Berkeley and Solano Avenue. This unique positioning provides residents with the best of both worlds – urban convenience and natural tranquility.

"If you are seeking architectural pedigree with 21st century sustainability and ease of living," Micco said, "this home checks all the boxes."

As the Bay Area real estate market continues to evolve, properties like 617 Grizzly Peak Boulevard become increasingly rare and valuable. At 2,650 square feet, this three-bedroom, three-bathroom home sits on a generous 5,140-square-foot lot, offering both indoor comfort and outdoor privacy. Its exceptional combination of architectural pedigree, breathtaking panoramic views, and carefully planned modern upgrades sets it apart from other properties currently available on the market.

"The Colbie House is more than just a mid-century home," Micco concluded. "It's a significant piece of Berkeley's architectural story, ready for its next chapter with new owners who will appreciate its unique blend of historical significance and contemporary functionality."
