Tucked in a convenient downtown location at the Pine Street shopping center in Morristown, Interiors at 40 Main has become a destination for customers throughout New York and New Jersey, says co-owner Nancy Casse. In 2002, Casse, an interior designer, and partners Marilyn DiColo and Julie Koza, who specialize in custom window treatments, opened their first location at 40 Main Street in Succasunna. A decade later, the trio has retained the name for their newly renovated 2,800-square-foot space, where furniture was recently added to the mix of fabrics, rugs, drapery hardware and other samples.

What makes Interiors at 40 Main different from other design firms in the area? “We’re fabulous,” says Casse. “And fun,” adds DiColo.

“We are user friendly. We listen to our clients’ needs,” says Casse. With a workroom on site, clients can view the progress of custom products throughout the design process. “Our industry is known for being pushy and not listening to the homeowner,” she says. “That’s the biggest complaint when we get a job from someone who has worked with a designer.”

The first appointment, explains Koza, takes place in the client’s home. That’s where the most important question is asked: What has to stay? Answers have ranged from rugs to plates. In fact, this team has designed a room around a single plate.

At the time of our interview, the designers were busy completing a renovation for a long-time client. After the loss of a family member, he wanted to surprise his wife with a unique gift when she returned from a two-week respite—a home makeover. The project included new draperies, blinds, painting, millwork, custom furniture and flooring. Despite the deadline, the partners were undaunted by the scope of the work. “We are good under stress,” Koza says.
