A better way to build on Cape Cod, Martha’s Vineyard, & Nantucket
M. Duffany Builders delivers a refined Design-Build process that brings clarity, coordination, and accountability to complex residential projects. By integrating design, planning, and construction under one disciplined approach, we streamline decision-making, control costs, and execute each build with precision from start to finish.
Building or renovating a home should be inspiring, not overwhelming. Our Owner’s Representative Services ensure your vision, budget, and schedule are protected at every stage—from planning and team selection to quality assurance and project completion. We act as your advocate, managing details so you can focus on enjoying the process.
Budget Control: Set budget, avoid scope creep, provide financial clarity.
Schedule Oversight: Track timelines, anticipate delays, keep things moving.
We do it all when it comes to improving your home, from bulkhead replacements, outdoor showers, windows, doors, and decks to expanded outdoor living. Maybe your home suffers from signs of old age, like rot? Our technicians have the know-how and experience to fix rot issues both common and unique to coastal structures. M. Duffany Builders understands the intricacies of building and maintaining a home on the water.
From morning routines to bathing, laundry or applying makeup before a night out, you spend a lot of time in your bathroom. Shouldn't you enjoy it? We can help design your dream bathroom and choose custom cabinets, lighting fixtures, hardware, tile and flooring, bath options, counter tops, and every other detail that you can (and can't) imagine. Then we will professionally install it all and get you back to living your life.
As your family grows and changes, what you need from your home changes too. From garages to finished basements or additions, we can help you get the most from your home's available space.
Your kitchen is much more than a place to cook food. It is a gathering place for your family and friends. A place for conversations. Stories. Laughter. It is the heart of many homes. We can help you design and build a custom kitchen that complements your style with modern features and comforts.
Summer and Fall Seasons seem all too short on Cape Cod & Martha's Vineyard. We can help you enjoy these cherished seasons by designing and installing the outdoor living space you need to entertain family and guests.
