National Council for Interior Design Qualification Certificate # 28 Dennis Duffy is the Principal of Duffy Design Group, Inc.

He began his design career in the Miami Design District, while
taking a break from his intended path to medical school and
having completed an undergraduate curriculum in Chemistry. Finding the world of interior design intriguing, Dennis moved to
New York City, and enrolled in a certificate program at Parsons
School of Design. “Being trained in science my entire life, but

1989, he opened his own design studio. He focused on both
residential and commercial projects, both in New York and
San Juan, PR. In 1996 he transitioned to Boston and joined

certification, as well as accreditation as a LEED Professional. He has served on the board of directors for the New England
Chapter of IIDA (International Interior Design Association) and

Atlantic Ocean views take center stage in this Gloucester, Massachusetts residence, where architectural integrity, natural beauty, and everyday comfort exist in perfect balance.

The interiors were thoughtfully designed to complement the home's strong architectural framework while reflecting its exceptional coastal setting. A refined palette of muted taupes, soft grays, creamy whites, and nature-inspired accent tones creates a sophisticated yet relaxed atmosphere throughout.

Natural materials, layered textures, and carefully curated furnishings bring warmth and livability to every space, reinforcing the home's seamless connection to the waterfront landscape beyond.

Great conversation at the latest B/A/D Talk!
Thanks to moderator Kyle Hoepner, and panelists Payam Bakhshi, PhD, PE , Catherine Truman, , and Jim Youngblood, for leading a thought-provoking discussion on the realities of competitive bidding and project estimating.
One of the biggest takeaways for me was the tremendous amount of time, expertise, and resources that architects, builders, designers, and subcontractors invest in preparing project estimates, often with limited information and no guarantee of being awarded the work. The conversation challenged attendees to think about why this model has become the industry standard and whether there are better alternatives.
I especially appreciated the discussion around client education and the importance of helping homeowners understand the value behind the preconstruction process. Accurate estimating requires collaboration, experience, and careful planning long before a project ever breaks ground.
These B/A/D Talks always spark meaningful conversations, and this one was no exception. It was great to hear diverse perspectives from both the panel and audience on how our industry can continue to evolve. And, great catching up with friends!

ROWES WHARF, BOSTON ✨
With front-row views of and Boston Harbor, this Rowes Wharf residence underwent a complete transformation. Unchanged since the building's completion in 1987, the unit was taken down to the studs and thoughtfully reimagined for modern waterfront living.
Originally a 2-bedroom, 2.5-bath home, the renovation included relocating the kitchen to the main living area to maximize functionality, add a third bedroom, and take advantage of the spectacular harbor views. A stunning renovation that combines contemporary comfort with one of Boston's most iconic waterfront settings.

As I sit listening to the celebratory fireworks for this 250th birthday of our country, I reflect on how we fought so bravely then to free ourselves of tyranny and despotism. When and why did we trade our ideals for cynicism and the “art of the deal”?!

A visit to the Met’s Costume Institute is always surreal—but this one hit differently. From Andy Warhol’s haunting wounded chest imagery to the meticulous craftsmanship stitched into every seam, the exhibit felt like a dialogue between vulnerability and spectacle. Fashion at this level isn’t just clothing—it’s narrative, identity, and cultural memory layered into fabric. Every piece told a story you could almost hear if you stood still long enough.
Grateful for the reminder that design, at its best, doesn’t just decorate—it reveals.

A Weekend in New York: Stepping Into “Eternal Nature”
A couple of truly inspirational moments from a recent weekend trip to New York perfectly captured the magic of the city—and one of the highlights was visiting the .
Tucked into the energy of NYC, the ARTE Museum offers something completely unexpected: nature, reimagined through digital immersion. Their exhibition, “Eternal Nature,” is more than something you simply look at—it’s something you step into.
From the moment you enter, you’re transported beyond imagination. Waterfalls seem to crash and cascade around you, not just visually, but in a way that feels almost tangible. You can stroll through fields of endlessly blooming flowers, their colors shifting softly with light and motion. The gentle whisper of the ocean follows you from room to room, blending seamlessly with a symphony of sound, light, and even scent.
What makes the experience so powerful is the way it invites you to slow down. In a city that moves fast, ARTE Museum creates a quiet space for reflection and wonder. It’s not just art—it’s a full sensory journey that reconnects you with nature in a modern, almost dreamlike way.
For me, it was one of those rare moments where time felt suspended. Just walking through these digital landscapes—surrounded by beauty, light, and sound—was both calming and energizing at the same time.
If you’re planning a trip to New York, this is one experience that truly stands apart.

House Tour 🏡✨ | York Harbor, Maine
A modern revival of a 1910 seaside gem. Once part of a Gilded Age summer colony, this oceanfront home was taken to the studs and thoughtfully reimagined—preserving its historic soul while embracing a clean, contemporary aesthetic.

A perfect balance of heritage, craftsmanship, and coastal ease. 🌊
