At Oak, an Accessory Dwelling Unit is designed with the same intention and craftsmanship as the main home it lives beside. Every material, every detail, every finish is chosen to reflect a standard that is instantly recognizable to anyone who sees it. This is not an addition. It is a statement.
A beautifully designed Accessory Dwelling Unit does something remarkable to a property. It elevates everything around it. Whether it becomes a private guest retreat, a creative sanctuary, or simply the most admired feature of your grounds, Oak builds it to be something you will never stop appreciating.
Your Accessory Dwelling Unit should look like it was always meant to be there. We design each structure from the ground up, shaped around your property, your architecture, and your vision. The result is a space that feels considered from every angle, because it was.
Oak has spent years building luxury homes across the South Shore for clients who expect more. When those same clients decide to add an Accessory Dwelling Unit to their property, they come back to us. Because they already know what happens when craftsmanship and vision meet, and they are not willing to settle for anything less.
An Additional Dwelling Unit is more than an extra building. It is a way to create meaningful space that blends seamlessly with your home and elevates how you live.
At Oak, an Additional Dwelling Unit is never an afterthought. It is a thoughtfully designed extension of your property, built with care and attention so it feels like it belongs from the very first day.
Every Accessory Dwelling Unit is a balance of creativity, function, and compliance. Our process makes the journey smooth while delivering a finished space that feels right at home on your property.
We start by learning how you want to use your ADU, whether for family, guests, or rental purposes, and the style that inspires you.
Together, we create a plan that makes the most of your space, selects materials, and ensures the design blends seamlessly with your main home.
We guide you through the requirements for building an ADU in your area, including Massachusetts guidelines for Accessory Dwelling Units, so you can move forward with confidence. This includes any site plans or engineering needed to assess your land for the option of an ADU.
Before construction begins, we handle approvals, order materials, and prepare the site to protect and respect your property.
Our skilled team manages construction from start to finish, focusing on quality, precision, and keeping the project on track.
We review every detail together, ensure the ADU meets your expectations, and leave you with a fully finished space ready for its purpose.
An Additional Dwelling Unit can be designed for so much more than extra space. It might be a serene retreat for visiting friends, a dedicated place for aging parents, a creative studio for your work, or a rental that generates steady income. Each project begins with understanding how you want the space to function and how it can enhance your property for years to come.

Yes! Certain ADU buildings may not qualify if it has a bedroom. Every system is rated for a specific number of bedrooms. If your home has maxed out your septic capacity a bedroom will not be allowed in the ADU if you do not remove one in the main house. We have extensive experience navigating this specific topic and can walk you through all the questions and complexities around it.
Your Accessory Dwelling Unit should be more than extra square footage. At Oak, every ADU project is an opportunity to build it better, creating a space that blends naturally with your property while serving your goals. From guest houses to pool houses, in-law suites to creative studios, we design and build for both beauty and purpose, giving you a place that works for today and adapts for tomorrow.
