Room Options

Three Rooms a Wellesley Basement Can Hold

Pick one or combine two, the plan follows your use.

A Home Office Away From Noise

Below grade, the house goes quiet. We plan outlets, network runs and task lighting around the desk, so a video call stays professional.

An In-Law or Guest Suite

Space for visiting parents or grown kids, with a bedroom, plumbing for a bathroom and a layout that gives both floors some privacy.

A Gym or Playroom That Lasts

Tough flooring and open space for weights, a rower or a kids' play area that can turn into a teen hangout a few years down the road.

Wellesley Rules Worth Knowing Early

Two town bylaws shape what a finished basement can become in Wellesley, MA.

Wellesley measures home size for its Large House Review as Total Living Area plus Garage, or TLAG. A basement counts only in proportion to how much of its outside wall sits above ground, and not at all below 25%. The town’s review rules also say that finishing existing basement space without altering the foundation is likely exempt.

Either way, the Building Department makes the final call, not the contractor. If an in-law apartment is the goal, Zoning Bylaw Section 5.13 governs accessory dwelling units and calls for a separate entrance that meets state building code for safe egress. The town’s latest ADU amendments took effect on April 15, 2025.

Quality Craftsmanship

What Goes Behind the Walls and Underfoot

Basement air acts differently than the floors above, so each layer is chosen for it.

Drywall Built for Basements

Standard paper-faced drywall can grow mold in a humid basement. We hang mold-resistant board instead, and we check the walls for moisture check the walls for moisture before anything gets closed in.

A Vapor Barrier Behind It

Between the concrete and the framing, a vapor barrier keeps ground vapor out of the insulation and studs. Nobody sees it once the room is done, yet it decides how long the room stays fresh.

Vinyl Plank Floors That Last

Luxury vinyl plank looks like hardwood but will not swell or cup on a concrete slab the way wood can. It shrugs off a spilled drink, a wet dog or a sticky July without lifting.
