Revere Wood Flooring has been installing, sanding and finishing wood-flooring in Somerville for more than twenty years, and a steady share of that work now lands in buildings that did not exist ten years ago. A backyard cottage is a complete small dwelling with one floor to get right, not a room bolted onto an older house. The scale changes what makes sense underfoot, and it changes how the job has to be sequenced.
We price a cottage the way we price a unit, by the finished footprint, the stair and the transitions, rather than by shrinking a whole-house number until it looks reasonable. On a plate this small there is nowhere to hide an awkward seam, a second lot of boards that runs a shade off, or a species that reads badly in the light the windows actually give. Every run is visible from every corner of the room.
What follows is how we work on a new small building here: what the floor has to carry, how it should relate to the house standing in front of it, and what we need settled before any material is ordered.
Floors for a New Somerville Backyard Cottage
Somerville rewrote its zoning ordinance on December 12, 2019, its first overhaul in thirty years, and that ordinance allows backyard cottages, including tiny houses. A September 2022 amendment made them buildable by right, dropping the site-plan review and the neighborhood meeting the 2019 version had attached. That side of the project belongs to the owner and the designer, and we take no part in it; our work starts at the subfloor, once the shell is closed in and the building can hold a steady interior climate.
The dimensions shape everything we order. A Somerville backyard cottage is capped at a 576-square-foot ground-floor plate plus a half-story loft, on 1.5 stories, with 3-foot side and rear setbacks. That is a floor we can lay in a short run of days, and a floor where a single bad decision is on show for the life of the building.
Laying out a 576-square-foot plate
Under six hundred square feet, plank direction stops being a default and becomes a design decision. We set the run along the longest sightline in the building, carry it unbroken through any doorway rather than dropping a threshold in the middle of the floor, and hold the expansion gap at the perimeter where baseboard and quarter round will cover it.
A small order is also a fragile one. Two hundred square feet of red oak pulled from a second lot can shift far enough in color and grain character to catch the eye across a room this size, so we buy the cottage as one lot with the waste factor already in it. Offcuts stay on site rather than going back, because the first repair this floor ever needs will want boards from the original run.
The half story above
A story and a half means a stair, and a stair is its own piece of work rather than a line folded into a square-foot number. We quote treads and risers by the piece, count the nosings separately, and say up front how the stair will meet the loft floor, because that junction takes the hardest wear in the whole building.
Lofts under a sloped ceiling carry less foot traffic than the main plate but sit closer to the warm air. We often run the same species up there in a narrower board, or a prefinished engineered floor where the knee walls make a site finish awkward to buff out cleanly. Whatever goes down, we measure the engineered wear layer first, because a thin one settles the question of whether that floor can ever be sanded.

Matching the Cottage Floor to the House in Front of It
Almost every cottage owner asks us the same first question: should the new floor match the main house? It is worth answering deliberately, because the two floors will rarely be seen in the same glance, and because the older floor is usually the one with the constraints.
Somerville’s housing stock is old by any measure. Of 37,756 housing units in the city, 22,264 were built in 1939 or earlier, which means the house at the front of the lot is often carrying early oak, old-growth pine, or a parquet border under decades of shellac finish that has gone orange with age. A new floor can be built to sit beside that, or built to be plainly its own thing.
Reading the old floor before promising a match
When the plan is to refinish the main house and lay the cottage to suit, we read the existing floor before quoting either. We check remaining thickness on old pine and early oak, because a floor that has already been sanded four times has very little left to give, and we identify what is actually down there: red oak, white oak, eastern white pine, or a mix where a radiator or riser came out and someone patched it.
Matching is then done with samples, not from memory. We put stain samples on the sanded floor itself, water pop where the species needs it to take color evenly, and let the owner look at them in daylight and at night before anyone commits. Sheen level gets chosen the same way, and we work within the Massachusetts coating limits, which are tighter than the federal ones and quietly rule out some products a national spec sheet will still list.
When not matching is the better answer
A century-old main-house floor and a brand-new one will never age together, and chasing a match usually means staining a new white oak floor dark enough to hide it. If that is not what the owner wants to live with, the honest move is contrast: a lighter, cleaner floor in the cottage that reads as a new building rather than a failed imitation.
That choice also frees the cottage to be specified on its own merits. Board width, grade and finish can then follow how the small building will actually be used rather than what the front house happened to be built with in 1910.
When the Cottage Is the Third Unit on the Lot
A backyard cottage that becomes a third dwelling unit on a Neighborhood Residence lot is permanently affordable. That is a condition on the unit rather than a specification for the floor, but it changes what we would recommend, because a permanently affordable unit is a long-horizon rental and the floor in it should be planned for years of tenancies rather than one.
The same 2019 ordinance set a citywide inclusionary requirement of 20 percent of new units affordable, so planning a small unit as a durable rental floor is ordinary here, not a special case. We would rather have that conversation before the order than after the first turnover.
A floor built for turnover
With one entry door and a single main room, foot traffic concentrates into narrow traffic lanes that will show first. We lean toward white oak for its tighter grain and higher Janka hardness, and toward a finish system that takes a maintenance coat well rather than the hardest possible film that has to be sanded off when it finally fails.
Site-finished waterborne polyurethane gives a seamless floor with no micro-bevels for grit to sit in, and it can be screened and recoated later without touching the boards. Hardwax oil is the other sensible answer for a small unit, because a scuffed area can be repaired in place instead of refinishing the whole plate. We explain the maintenance each one asks for, since the choice outlives the tenancy that prompted it.
Turning a unit around between tenancies
A vacant unit is a deadline as much as a job. We schedule vacant rental floors to finish inside the window before the unit is signed off and re-let, which usually means a screen and recoat with a fast return to service rather than a full resand that the calendar cannot absorb.
When a full sand is genuinely needed, we say so early enough for the owner to plan around it instead of discovering it the week before a lease starts. Pet urine stains, water stains around an old radiator location and hollow spots in the subfloor are the three findings that most often turn a recoat into a real refinish.
Planning a Small-Unit Floor Project in Somerville
Somerville is the most densely populated municipality in New England at 4.12 square miles, and a back yard reached past a house on a narrow lot is a logistics problem before it is a flooring problem. Most of what makes a cottage floor go smoothly is decided in the week before we arrive.
Getting material through the yard
With 3-foot side and rear setbacks, there is no backing a truck to the door. Material is carried down the side of the main house by hand, which sets how much can be staged at once and makes the delivery window part of the schedule rather than an afterthought.
That route runs past the finished floors of the house in front, so we protect them before the first bundle moves. Dustless sanding with a HEPA vacuum matters more than usual on a lot this tight, because the sander is running a few feet from a neighbor’s windows and our own path back out.
Acclimation and moisture
We meter the subfloor and the boards before anything is fastened, and we do not start while the two readings disagree. A new small building needs its heat running and its interior finishes dry first, or the floor that goes down flat in month one shows board gapping by the first winter and cupping the following summer.
Acclimation in a 576-square-foot building is quick compared with a whole house, which tempts people to skip it. We would rather hold the start by a few days than fasten a floor to a moisture condition that is still moving.
If the new unit is inside the existing house instead
Some owners decide the extra unit belongs in the house they already own rather than in the yard. In a two-family we work one floor at a time, so whoever lives on the other floor stays in the house while the sanding runs, and we sequence the noisy days where they do the least damage to a working week.
In any house of that age we read the build year and the painted surfaces before the sander is switched on, because Massachusetts runs its own lead-safe renovation rules on homes built before 1978 and the Massachusetts Lead Law is not something to discover mid-job. On a lot where the front house is from the 1920s and the cottage behind it is new, those two floors are effectively two different projects, and we quote and schedule them that way.
