In Millburn, our full-service practice designs homes and commercial interiors with equal attention to appearance and use. Residential work includes kitchens, suites, and living spaces; business projects include offices, reception, and shared areas. Space planning, materials, lighting, furnishings, documentation, and project coordination are developed around the individual brief.
Bring a new direction to your home with rooms that feel connected, comfortable, and distinctly yours.
Create a complete interior, from a new home to rooms that need a thoughtful update around pieces you love.
Express your organization’s identity in spaces that welcome visitors and support the people who use them every day.
Kitchen and bath design — Layouts, cabinetry, lighting, and finishes designed as part of the home.
Workplace interior design — Offices, meeting spaces, reception areas, and shared interiors.
Healthcare interior design — Medical and dental interiors planned for patients, staff, and daily use.
We start by identifying what you value in the existing interior and what no longer works. That may mean retaining woodwork and a dining table while changing the seating arrangement, storage, or lighting. New selections are developed around those decisions.
In a professional office, reception and meetings should not disrupt private work. We plan the routes visitors use and the space staff need for concentration and storage, then select furnishings and materials that reflect the business.
The JR Cruz headquarters in Holmdel uses height-adjustable desks, reclaimed barn wood, and industrial lighting in a converted bank branch.
Every project moves through the same five steps: initial consultation, design development, project & construction management, final walkthrough, client satisfaction check-in. Read the five steps.

I've had the privilege of working with Beth Insabella on several homes throughout the past 25+ years. Beth has impeccable taste and with her talented team, each project was a testament to her firm's creativity, expertise, attention to detail and professionalism. Whether starting with a blank slate or repurposing existing furnishings with new fabrics and colors, INSABELLADESIGN delivers stunningly beautiful, yet highly functional spaces, specifically tailored to the client's needs. I look forward to our next collaboration!
I must say it's been my pleasure to have had the opportunity to work with Beth and her team at Insabella Design. My boss has been a long time client of Beth, over 25 years. And over those many years I was fortunate enough to work with Beth directly. She is extremely attentive and knows exactly what needs to be done. She has designed numerous major renovations and reconstruction projects for us. She has always been a pleasure to work with from the beginning of the projects to the very end. If I ever needed something in a pinch she always makes it happen. I would be completely lost without her and her support in keeping my boss comfortable and happy. Thank you Beth, to you and your team for your excellent services.
As an architect with considerable experience with differing project types, working with Beth and her staff has been a pleasure. Beth's team brought a fresh approach to the tired-looking interior of a subsidized housing midrise project built in the 1970s. Insabella Design is a highly skilled, motivated, and reliable firm that can be an asset to any interior design project. She and her team are dependable and committed to achieving excellence in their work. I look forward to working with Beth on our next project.
Yes. We review the layout, architectural details, and furnishings you want to retain, then identify the changes that would improve comfort and everyday use. That discussion helps set the scope before new materials or furniture are selected.
We discuss the users, purpose, existing conditions, and priorities for each space. From there, you know which rooms and services are included and who the interior work has to be coordinated with.
The rooms involved, extent of renovation, custom work, product availability, building requirements, and installation needs all affect the project. Share your priorities and anticipated investment at the initial consultation; a detailed proposal follows that conversation.
Yes. We coordinate the agreed interior design scope with the relevant project professionals. Design, engineering, construction, and approvals have different responsibilities, which should be established for the individual project.
