Room Additions in Andover
A New Room for Your Andover House
In Andover, a room addition can join an older house near the historic center, a mill-era home in Shawsheen Village, or a colonial or cape in the newer neighborhoods farther out. We plan the new room around that particular house, from the foundation extension and framing to the systems and finishes, so it reads as part of the original.
Typical room additions in Andover:
- Bedroom additions on Andover capes
- Family rooms behind colonials
- Home offices with data wiring
- New bathrooms tied into existing plumbing
- Additions matched to mill-era homes

Where a New Room Meets an Andover Home
An older house near Phillips Academy can have floor heights and framing that a new room must follow closely, while a newer home off I-93 or I-495 can be simpler to match. Either way, zoning and setbacks are checked before design, and we confirm how much the panel and HVAC can take on.
Where the new room meets the house:
- The floor height of the existing house
- The existing roof the new roof ties into
- Existing framing the new walls fasten to
- Panel and HVAC capacity
- Siding and trim to match
Clear signs an added room may fit your home:
- You want one more bedroom or a second bathroom
- Your home lacks living and storage space
- Rearranging rooms will not add the square footage you need
- You need a private suite with a bathroom
- Working from home calls for a real office
We measure the lot and the house on the first visit and confirm zoning and setbacks before design, so the new room is designed around what the lot allows and how the existing house is framed.

FAQ
Room Additions in Andover: Common Questions
Here are answers to the questions Andover homeowners ask most about adding a room. We cover permits and zoning, how the addition ties into the house, the types of rooms you can add, and how to start. Something else on your mind? Give us a call and we will explain.
Do I need a permit to add a room in Andover?
Yes, you do. Building a room addition calls for a building permit and, in most cases, a zoning review for setbacks and lot coverage, since the house grows. ML20 General Construction files the applications, books the inspections of the foundation, framing, systems, insulation, and final work, and keeps each phase ready for the inspector.
How does a new room connect to my Andover house?
Four points matter most. The new floor lines up with the existing floor because the foundation is set to that height; the addition walls attach to the old framing; the roofs join under flashing that keeps water out; and a header takes the weight above the doorway into the house.
What types of rooms can you add?
Most everyday rooms can be added. We add bedrooms for growing families, home offices for remote work, bathrooms, bigger living rooms, and master suites that combine bedroom, bath, and closet. The type you choose shapes the systems, the layout, and the cost, so we compare the options together at the first visit.
What is the first step for adding a room in Andover?
Step one is a no-cost in-home estimate. Book it online or call (978) 917-9072. We look at the house and the lot in Andover, go over the room you have in mind, look at zoning and setbacks, and follow up with a clear written estimate before any design work. No obligation applies.
