Set on 35 scenic acres in an area called Lemon Gulch in Castle Rock, this 6,500-square-foot residence reflects the personality, passions and lifestyles of the young owner couple.

Perched on a bluff to best capture sweeping 180-degree views, the home is a study in contrast—robust in structure with its rusted steel, concrete, plaster and wood exterior, yet intimately scaled inside to feel comfortable and livable. It celebrates the surrounding landscape while reflecting the owners’ individual lifestyles.

A little backstory: The owners moved to Colorado almost 10 years ago while they were at the beginning stages of their careers as doctors. To accomplish the design of the home, the couple enlisted the help of architect Greg Jones, founder and managing principal of Greg Jones Architecture, based in Placerville, California. “We contacted him very early on in the process and said, ‘Why don’t you fly out and have a little visit and we will look at property together?’ and so he did,” recalls the wife.

Jones, who happens to be the husband’s brother and specializes in new residential work, was the perfect fit. Establishing that the couple wanted an industrial-style, mostly single-level house that brought the outside in, he went through his process of hand-sketching some ideas. “They were iterations of sketches that were later refined down to the final floor plan,” Jones says.

Kitchen and Dining Area The kitchen and dining areas feature complementary finishes, including terrazzo floor tiles and colored plaster walls. Cabinetry is vertical- grain white oak by builder Mark Person. Island pendants are by Visual Comfort; counter chairs by CB2. | Photo: David O. Marlow

From the beginning, the “big concept” was to establish a large, linear exterior wall with a faux concrete finish that defined the edge of the living space and separated the private and public spaces. Outside, a butterfly-style roof over the entry and main living spaces angles up from a central point over the front door and over a large wall of windows with 180-degree views at the back.

“It’s my favorite part of the project, a unique feature that pulled the whole house together and gave it a very modern aesthetic,” says Jones. Builder Mark Person of Mark D. Person Homes in Parker helped bring the project to fruition.

For help with the interior design, the couple consulted with Marybeth Norton, design principal of Norton Design Approach in Palm Springs, California. “We took a few trips to California with her to pick out things like materials and countertops, and then we chose color schemes for the individual rooms, which actually just kind of evolved,” says the wife. “Marybeth also came out here several times to oversee progress and optimize design. She helped us to accumulate furnishings over time, always keeping us in mind.”

Says Norton, “The couple envisioned a residence that not only celebrated the Colorado landscape but also reflected their individual lifestyles.” She also helped choose finishes in certain rooms, such as the concrete-finished walls in the entry and living room and the terrazzo floor tiles in the kitchen. Items that the couple brought back from their travels provided finishing touches.

After living in the house for several years, the wife sums up their feelings about it: “It’s our dream house. It came together really quickly, and we really can’t imagine anything better. It reflects our lifestyle, our personalities and what we desired in our house. We love it.”
