Roxane Mosleh is a full-service interior design agency that works on myriad projects, including commercial, multi-family, hospitality, and high-end residential real estate. Mosleh’s credentials include interior designer designations of Allied ASID, Associate IIDA, and New York State Licensed Real Estate Agent with the luxury property brokerage Saunders & Associates, though she also has a Florida broker’s license.

Working with builder, Brett Poleshuk Construction, Mosleh helped transform a 1970s beach house in Shelter Island into a modern year-round masterpiece for its owner, a private investor. According to Mosleh, the multi-level, 3000-square-foot home underwent a complete re-facing and remodeling of its original structure, which required an excavation to add an egress on its lower level. To modernize the structure, a new standing seam steel roof was installed. New flooring, walls, kitchen, and bathrooms were designed and featured a mix of modern materials, such as lacquer paint on kitchen cabinetry and porcelain tile throughout. The kitchen features all Sub-Zero and Wolf appliances.

For design, cool and warm gray tones were used to project a contemporary interior design aesthetic. In addition to the general contractor, key subcontractors included Rockman Millwork, which provided all custom millwork, Westhampton Glass, which provided all windows and glass used in the project, and Ferguson, which provided fixtures for the kitchen, bath, and other rooms in the home.

In addition to building permits, the project required Department of Environmental Conservation approvals due to the property’s waterfront location. It also was necessary to install a new electric service and state-of-the-art “Reclaim our Water” wastewater treatment system in compliance with the local municipality’s current regulations.

The project, which began in the spring of 2018, was completed in January 2020.

Mosleh also has the distinction of being the owner of the first Missoni Home retail store and today continues to market its products, including the recently launched Missoni Home 2020 collection.

Mosleh, who resides in Southampton, New York, and Florida, is the wife of professional equestrian/jumper rider, Bobby Ginsberg, who is also a realtor with Saunders and owners the Riverhead-based Bobby Ginsberg Show Stables, a successful equestrian center. The couple has one young son.

We caught up with Mosleh to learn more about her high-end interior design work and where her work is taking her.

Roxane, do you work on the East End regularly?

Yes. I am based out of Southampton and I have many projects in the Hamptons, Shelter Island, and the North Fork.

How did you get into interior design?

My father was a builder, so I think it’s in my blood. I’ve always had a passion for interior design, architecture, and construction, and I formally studied interior design.

The renovation of this beautiful 1970s beach house involved transforming a traditional beach house to a modern home?

Yes, that’s correct. The home underwent a complete re-facing and remodeling of its original structure, which required an excavation to add an egress on its lower level to create a modern design.

Did you have to deal with preservation organizations considering it is a home from the ’70s?

No, but we did have to work with the Department of Environmental Conservation approvals due to the property’s waterfront location.

You worked with Brett Poleshuk Construction for the demo and build. Do you work with them and other builders regularly?

I work with other builders regularly, but this was my first project working with Brett Poleshuk. He was a pleasure to work with; a real wealth of knowledge and very prominent in Shelter Island.

How would you define your interior design style?

I favor a modern minimalistic style. However, each project and its unique architecture demands its own style.

For the renovation, what were some of your inspirations?

We reference the renowned Antonio Citterio. He is based in Milan and is a well-respected Italian architect, furniture designer, and industrial designer.

What were you happiest with in the design of this home?

We excavated the lower level of the structure to be able to put in full-length sliding doors. This, along with the color palette we selected, enabled us to transform a very dark interior to a natural light-filled interior.

As a designer, what resources do you go to for inspiration?

Art history, design history, travel – especially to Italy and other parts of Europe, as well as India. I am also inspired by technology and innovation and new materials.

If money were no object, what would you love to design?

I probably would love to design a modern equestrian farm environment, as so many farmhouses are traditional designs. I would love to create a modern farmhouse featuring newer materials in innovative ways on preserved lands and create a green, sustainable structure.

Do you have a favorite architectural and interior project anywhere in the world?

Not any particular project, but I do love the work of the architect Zaha Hadid. One of her more recent projects that was particularly impressive was the One Thousand Museum, a high-rise condominium in Miami. I also like the work of Frank Gehry, another architect who is known for very innovative and futuristic designs.

What are you currently working on?

I am currently working on renovating two beach houses; one in East Hampton and another in Southampton. I am also working on a new construction project.
