What We Build
Designed for Living Together
Families end up needing an in-law suite for all kinds of reasons. A parent moving in after living alone got harder. A grown child staying for a while as they figure out their next step. Or simply wanting everyone close without everyone tripping over each other in one kitchen.
Whatever the reason, the goal is the same: real, separate living space that doesn’t feel bolted onto the house as an afterthought.
That’s not a finished basement with a mini fridge in the corner. It’s a suite built with its own entrance, its own kitchen, and genuine privacy, designed into the home’s architecture rather than wedged into whatever space happened to be available. Done right, it doesn’t read as a compromise. It reads as its own home.
How It Works
What We Think About When Building
The things that determine whether an in-law suite works are rarely visible in a rendering. You notice them months later, once someone is actually living there.
Does the kitchen get used, or does it just look good in photos? Is there enough storage that things don’t end up in boxes? Do sounds carry through the shared wall? Does getting to the suite mean walking through someone else’s living room?
Here’s what we build around:
- A private entrance, with real separation from the main house
- Sound isolation that actually holds, not just drywall over a shared stud wall
- A kitchen sized for daily cooking, not just reheating leftovers
- Natural light, since a windowless suite reads as institutional no matter the finishes
- Storage built in from the start, since these spaces tend to become long-term homes
- Accessibility considerations if aging in place is part of the picture. If that’s the main driver, our accessibility design page covers what universal design looks like in more depth.
DC rowhomes don’t leave much room for error. Narrow lots, shared walls, neighbors close on either side. We know where the real constraints are in this city, and how to design around them so the finished space doesn’t look like a workaround.
Why Blue Star
The Right Team Makes All the Difference
Most in-law suites fail for the same reason: the entrance still runs through someone else’s kitchen, or the walls carry every sound from the room next door. Fixing that after the fact is expensive and often impossible. Getting it right means thinking about separation and privacy before a single wall gets framed, not after.
That’s where having one team handle both design and construction matters. Our architects and builders work from the same plan from day one, which means privacy isn’t something we retrofit once the layout is already set, it’s baked into the layout itself. Everything comes back to three things: Lifestyle Driven Client Design, Craftsmanship with Architectural Details, and a Transparent Process.
Lifestyle Driven Design
An in-law suite starts with understanding how your household actually lives, today and going forward. We design around your family’s specific needs, your home’s existing layout, and how much independence the suite needs to offer, so the finished space works for everyone in it without feeling like a converted afterthought.
Craftsmanship & Quality Details
The goal is a suite that feels like its own home, not a modification of someone else’s. A kitchen sized for daily use. A private entrance that actually feels private. Sound isolation you can’t hear through. We are deliberate about every detail that determines whether the finished space feels designed or repurposed.
A Transparent Process
In-law suite projects in DC can involve zoning considerations, DOB permitting, and in historic districts, preservation review. We manage all of it and keep you informed at every step. You will know what your project requires, what the timeline looks like, and what drives the budget before any work begins.
Let’s Figure Out What’s Possible
Consultations with us don’t involve a sales pitch. We spend most of the time asking questions, about your household, how the space needs to function, and what’s realistic for your specific home before we ever talk numbers.
Some homeowners already know exactly what they want. Others just know something needs to change and aren’t sure what that looks like yet. Either way works. By the time we’re done, you’ll have a clear sense of scope, a realistic timeline, and whether any DC funding programs apply to your project.
If an in-law suite has been on your mind and you don’t know where to start, that’s exactly what this conversation is for.

Happy Clients
Blue Star’s best trait is their attitude. Everyone is unfailing polite, even when things got hard. And when things went wrong, which I fully anticipated would happen, you guys did the right thing every single time.
When you buy from Eric and his team, you can rest assured that they will address problems your inspectors couldn’t see.
The craftsmen used were excellent. We were impressed with their work and attitude and ability to creatively work around issues. The addition seamlessly integrates into the rest of the house and it’s hard to believe that the new spaces haven’t always existed as part of the original home.
Blue Star loved the architectural and design challenges I handed them, and each time I came up with a new idea, they were driven to figure out the best way to deliver.
I was very pleased with my experience with Blue Star. The reason for the top 5-star rating is three fold- the quality of the work, the prices they obtained for materials and the design elements. I did a large renovation (kitchen, 3 bathrooms, HVAC, plus knocked down some walls) which took about 4 months.
Blue Star came in on budget and ahead of a very, very tight and critical schedule. We highly recommend them to anyone considering a renovation.
