Residential Architects and Interior Designers in Charlestown, MA

Make your Charlestown home really feel like yours.

Hi, we’re JtA.

We design homes in Charlestown that people love to live in—spaces that feel right the moment you walk in, and keep feeling right for years after. From the Navy Yard to Monument Square, we listen first and design second, working closely with homeowners so the final space reflects your taste and how you actually live. After all, it's your home—it should feel like it.

But above everything else, we're genuine, down-to-earth people who pride ourselves on designing in a very personal, hands-on, and service-focused way.

What Charlestown homeowners usually want to know.

Do I need an architect to renovate a house in Charlestown?
Generally speaking, if a permit is required for general construction, you’ll need an architect’s stamp. If you’re looking just to replace finishes or fixtures, you may only need electrical or plumbing permits and might not need an architect. Charlestown permitting runs through Boston Inspectional Services. Most housing in Charlestown is attached—rowhouses share party walls, sit on small lots, and take daylight from two ends only. That changes what's structurally possible, what your neighbors are entitled to, and how the work has to be sequenced. We’ll help you understand all of this before getting started.

Is my house in a Charlestown historic district?
There are several historic districts in Charlestown, and they each do different jobs—National Register of Historic Places, Neighborhood Design Overlay District, and Boston Landmarks District.

The National Register districts in Charlestown include Monument Square, Town Hill, and the Navy Yard. National Register listings are essentially honorary. They carry tax incentives for some qualifying rehabilitation work, and do not restrict what you do to your building.

The Neighborhood Design Overlay District covers most of central Charlestown, and includes sub-districts: Town Hill, Monument Square, Breed’s Hill, Union Street, and Bunker Hill. Within these districts, zoning is regulated and there are specific design guidelines for exterior changes.

Lastly, the Boston Landmarks Commission has been studying whether Monument Square should become a designated landmark district, which would be Charlestown's first. If that goes through, the BLC would review proposed changes to your exterior.

Can I add a roof deck or change my windows?
The Neighborhood Design Overlay District guidelines cover exactly the things Charlestown homeowners most want to change—rooflines and window patterns. A roof deck, a headhouse, a dormer, or a change to the size or arrangement of front windows all land within the guidelines’ scope, and what's workable depends partly on what's visible from the street.

Will my project trigger Boston's demolition delay?
It’s likely it could. Boston Zoning Code includes a demolition delay policy called Article 85, which applies to neighborhood buildings at least 50 years old, and separately to any building inside a Neighborhood Design Overlay District regardless of age. Most of Charlestown sits inside a Neighborhood Design Overlay District, so the demolition delay may apply to your project if the scope of demolition work triggers review.

Inspectional Services won't issue a demolition permit without a determination or an exemption. So this step is an important part of the process to plan for. The upside is that the delay is short. If the Landmarks Commission determines that demolition delay applies, the delay runs 90 days from the close of the hearing—considerably less than several neighboring communities impose.

Do I need an interior designer as well as an architect?
Interior design is an incredibly important part of residential design projects. Finishes, fixtures, millwork, lighting, in addition to furniture and decor, are all key parts of home design. That’s why our team consists of both architects and interior designers who work collaboratively with you to create holistic and complete spaces. A Charlestown rowhouse can have a demanding interior. Houses are narrow, deep, and attached on both sides, so daylight arrives from the front, back, and sometimes the roof. Everything in the middle depends on how you handle openings, sightlines, and where light is allowed to travel. Built-in storage stops being a nice extra and becomes the reason the house works at all.

Our team includes both architects and interior designers who work together on your project from the start. It also makes your life easier, since our designers handle material, finish, and fixture selection and sourcing. And it's all through one partner, us, so there's less to manage, fewer surprises, and smoother communication.

We share party walls with our neighbors. What does that mean for a renovation?
A few things worth raising early. A party wall is a shared structure, so anything that loads it, cuts into it, or alters it becomes a conversation with your neighbor as well as with the city. Sometimes this is a legal question about rights recorded on the deed, which is a discussion for a real estate attorney. Fire separation between attached dwellings is a code requirement, and older rowhouses often don't meet current standards until someone opens a wall and finds out.

What makes Charlestown, Charlestown.

Charlestown was settled in 1629, a year before Boston. On June 17, 1775, during the Battle of Bunker Hill, the British burned almost all of it in a single afternoon. What stands now went up afterward, largely in the few decades that followed. That's why Charlestown is so charming and desirable. Monument Square, Town Hill, Breed’s Hill, Thompson Square, City Square: about a square mile, walkable end to end, and remarkably consistent architecturally.

That consistency is what the rules here are built to protect. Most of central Charlestown sits inside a Neighborhood Design Overlay District, setting guidelines for things like rooflines and window patterns. Several National Register districts also exist. And the Boston Landmarks Commission has been studying whether Monument Square should become Charlestown's first designated landmark district.

That's a lot going on in one small Boston neighborhood, and it's a reason to work with architects and interior designers who know Charlestown well. We’re based next door in Somerville and we know how to work with exactly this housing stock. The middle room with no window in it. The garden level that's been used for storage for forty years. The roof with a harbor view you can't get to.

Charlestown rebuilt itself once already, from almost nothing. Adding to it carefully is an important job, and we'd like to help with yours.
