Rare midcentury modern in Hilltop lists for $2.6M after renovations
Transforming Hilltop’s Tree House into a Modern Sanctuary
When Hilltop’s Tree House hit the market in summer 2023, Jon Troshynski and Eddy Doumas were concerned that the midcentury modern gem would be demolished by the new owner.
This 3,000-square-foot home in the 100 block of N. Dexter St., once showcased in a 1969 Life magazine article, was originally designed by Richard Quinn for Dr. Herbert Rothenberg.
Located near Cranmer Park on a 10,000-square-foot lot, the house, built in 1967, stands out for its unique wood siding, a departure from typical midcentury modern architecture.
Described as a charming time capsule, Troshynski, a realtor with Compass-Denver, and Doumas, the owner of Worth Interiors, purchased the property for $2.1 million in August 2023.
Together, they undertook a renovation project to transform the home into a modern, light-filled sanctuary while preserving its architectural integrity.
“Our goal was to elevate the home to a new level of excellence and bring it up to contemporary standards,” explained Troshynski.
Originally featuring four bedrooms and three bathrooms, the property now boasts a luxurious three-bedroom, four-bathroom layout.
The top-floor primary suite includes a sleeping room, an office, a custom walk-in closet, and “his-and-his” bathrooms, one of which features laundry and storage space.
The primary suite was designed with flexibility in mind, allowing the office to be converted back into a bedroom, offering the option for multiple bedrooms on the top floor, according to Troshynski.
Troshynski and Doumas revamped the compact 1960s butler’s kitchen and separate laundry room into an open kitchen with brand-new custom cabinetry, porcelain countertops, and built-in appliances.
They also transformed a screened-in porch into a sunroom, with plans for a future deck expansion.
Additional upgrades included replacing non-functional windows, applying fresh paint, installing a new roof, and updating the electrical and plumbing systems.

“The highlight of waking up in this treehouse is the journey through it,” shared Troshynski.
“Walking along the catwalks in all seasons feels like being one with nature— the fresh green of spring, the lush canopy of summer, the vibrant hues of fall. And in winter, witnessing a snowstorm swirling 360 degrees around you is truly magical— an experience I never imagined having in my own home.”
As they divide their time between Denver and Arizona, Troshynski and Doumas have decided to downsize their Denver residence and are offering the 3,000-square-foot home for sale at $2.6 million.
While acknowledging the bittersweet nature of their decision, Troshynski expressed hope in finding new owners who will cherish the home as they did.
“I am excited to pass on this masterpiece to its next owner,” Troshynski stated. “So they too can enjoy the beauty, comfort, and connection to nature that makes 145 Dexter truly extraordinary.”
