Denver Tech Center luxury penthouse owned by developer hits market for $3M
The Luxurious Penthouse of Denver Developer John W. Madden Jr. Goes on the Market for $3 Million
Renowned Denver developer John W. Madden Jr.’s penthouse, where he lived for decades, has been relisted for sale at the price of $3 million. The 5,500-square-foot residence, located atop the office building at 5700 S. Quebec St. in Greenwood Village, offers a unique glimpse into the personal sanctuary of the man who played a significant role in shaping the Denver Tech Center skyline.
This penthouse, possibly the only one of its kind in the Denver metro area built atop a commercial office building, features three bedrooms, four bathrooms, and nearly an acre of private outdoor space with stunning Front Range views.
Listing agent Anne Dresser Kocur of LIV Sotheby’s International Realty describes the property as “very special” and “one of a kind,” offering a feeling of being on top of the world while being in the heart of Greenwood Village.
John W. Madden Jr., who passed away in 2024 at the age of 94, had previously attempted to sell the penthouse for $6.8 million in 2021. He had built the office building in the late 1970s and added the residential penthouse as an afterthought during construction.
The current space, with no load-bearing walls, presents a perfect canvas for potential buyers to unleash their creativity and imagination. Features include skylights, hardwood floors, Italian travertine tilework, antique doors with etched glass, marble fireplaces, and a walk-in wine locker.
With mixed-use zoning allowing for residential, commercial, or combined use, the penthouse awaits a special buyer who can fully appreciate its unique attributes. The standout feature is its expansive rooftop deck, perfect for hosting various events or creating a private retreat.
Unlike typical condominiums, the property has no homeowners association dues, potentially saving owners thousands of dollars each month. The John Madden Trust has already completed extensive due diligence and permitting for an additional private elevator, offering the next owners a head start on their vision.
John W. Madden Jr.’s legacy is deeply ingrained in the property, as he was responsible for developing numerous projects in Colorado, including the iconic Fiddler’s Green Amphitheatre. His emphasis on art and landscaping has left a lasting impact on the Denver Tech Center’s architectural landscape.
