One more room,with all the questionsof a whole addition.
A single-room addition is smaller than a wing, but the setbacks, the foundation, the tie-in and the permit are the same conversation. Getting that clear early is what keeps it small.
Small in floor area. Not small in process.
People expect a single-room addition to be a fraction of the effort of a large one, because it is a fraction of the square footage. It is not, and the reason is that most of the work is fixed cost regardless of size.
You still need a foundation designed for your soils. You still need the roof tied into the existing one so it does not leak in ten years. You still need the new structure connected to the old, the services extended, the envelope sealed where new meets existing, and the whole thing drawn, engineered and permitted. None of that halves because the room is half the size.
What that means practically: the cost per square foot of a small addition is higher than a large one, and it is worth sanity-checking whether the room you want could instead come from replanning space you already have. Sometimes it can. Often it cannot, and then this is exactly the right project.

Six fixed costs, whatever the room size.
Setbacks & coverage
Whether the footprint is available at all. Answered by the parcel, before anything is drawn.
Foundation
Designed for your soils and frost depth. The same engineering whether the room is 200 or 600 square feet.
Roof tie-in
Where new roof meets old. The single most common source of leaks on additions done badly.
Structural connection
New framing tied into an existing wall that was not built anticipating it.
Services extension
Electrical, heating and often plumbing run from a system sized for the house as it was.
Drawings & permit
A full permit set and a review cycle, identical in process to a much larger addition.
Before you price a room addition, price replanning. If reworking the existing floor area gets you most of what you want without a new foundation, a roof tie-in and a permit cycle, that is worth knowing first. We will tell you if it does.
Six steps, and the first one is a phone call.
Discovery call
A short call to understand the project, the property and whether we are the right fit.
Job walk
We look at what is actually standing — structure, services, access.
Design
Drawings worked through with you, so you approve a plan rather than imagine one.
Engineering & permitting
Structural engineering and the permit set, handled by us.
Construction
One project manager, and a job site kept clean because you usually still live here.
Walkthrough
We finish the list you write, not the one we think is left.

Tell us what the room is for.
Not just how big — what it needs to do. That decides where it should go, and occasionally reveals you do not need to build it at all.
