For nearly 30 years, Masters Touch Design Build has helped Westwood, MA homeowners add space, comfort, and value to the homes they love. If you are looking for a home addition contractor in Westwood, we design and build additions of every kind, from a single-room bump-out to a full second story, alongside kitchens, bathrooms, and whole-home renovations. One team handles design, permitting, and construction, so your project stays on budget and on schedule from the first conversation to the final walkthrough.
Home Additions in Westwood
A well-planned addition is one of the smartest investments you can make in your Westwood home, especially when moving is not the answer. We design home additions in Westwood that look like they were always part of the house, matching rooflines, siding, and trim so the new space feels seamless inside and out.
Common Westwood additions we design and build:
- Family room and great room additions
- Kitchen expansions and bump-outs
- Primary suite and second-story additions
- Mudrooms, entryways, and home offices
- In-law suites and accessory dwelling units (ADUs)
- Garage additions and bonus rooms above
Because we are a design-build firm, you work with one team from concept through completion. We establish a realistic budget range early, usually within a tight margin, before any detailed design work begins, so there are no surprises later.
Building an Addition in Westwood: Permit Requirements
Nearly every home addition in Westwood requires a building permit from the Town of Westwood Building Division at 50 Carby Street. Projects that change your home’s footprint also require a certified plot plan. A typical submission includes two sets of construction plans, an energy compliance form, a Workers’ Compensation affidavit, and a signed homeowner’s authorization. Permit review can take up to 30 days. Accessory or in-law apartments carry an extra step: they require a Special Permit from the Westwood Zoning Board of Appeals. We prepare and file all of this for you and build the review time into your schedule.
(Requirements current as of 2026; we confirm the latest rules with the Town on every project.)

Featured Westwood Projects
Project Briar III
A full first-floor remodel and addition that finally gave this Westwood family the room they’d long wanted, including a spacious new kitchen, walk-in pantry, powder room, laundry room, sunroom, and mudroom. What was once cramped and short on storage is now an open, organized home built to enjoy for years.
Project High
This 1700s Westwood antique was full of character outside but dark and closed-off within, with a small, low-function kitchen. Two additions opened it up with a vaulted family room off a brighter new kitchen, while interior wood beam accents and reclaimed pine floors keep the home’s historic charm intact.
Project Greenacre
This Westwood home had sat vacant for years, frozen in time down to a 2004 calendar still on the wall. We reworked it throughout, removing walls, reconfiguring windows, adding interior square footage, and updating every finish to create an interior that feels brand new.

Home Addition FAQs for Westwood Homeowners
Do I need a permit for a home addition in Westwood, MA?
Yes. Any addition that changes your home’s footprint or adds an upper level requires a building permit from the Westwood Building Division. A typical submission includes two sets of construction plans, an energy compliance form, a Workers’ Compensation affidavit, and a signed homeowner’s authorization. Permit review can take up to 30 days. Masters Touch prepares and files everything for you and builds the review time into your schedule.
How long does a home addition take in Westwood?
Most additions take roughly six to twelve months from design through completion, depending on scope and permitting. Because Westwood permit review can take up to 30 days, we start the approval process early and reserve a placeholder in our construction schedule so your project keeps moving.
Do I need an architect for an addition, or can Masters Touch handle the design?
You do not need to hire a separate designer first. As a design-build firm, Masters Touch handles design, engineering, permitting, and construction under one roof with a single point of contact. That keeps your budget in the conversation from day one and closes the gap between a plan that looks good on paper and what it actually costs to build.
Can I add an in-law suite or accessory apartment in Westwood?
Often, yes. Accessory or in-law apartments in Westwood require a Special Permit from the Zoning Board of Appeals in addition to a building permit. We evaluate your lot, zoning, and goals up front and manage the approval process so you know what is possible before you commit.
What areas of Westwood does Masters Touch serve?
We serve homeowners throughout Westwood, including Islington, the University Station area, and Westwood Center, along with neighboring communities such as Dover, Medfield, Needham, and Norwood.
