The narrow row, the half-story above it, and the storage nobody drew.

Windsor Terrace is the part of western Brooklyn that never got grand. It sits in the notch between Prospect Park and Green-Wood Cemetery, and it was built mostly between the 1890s and the 1920s for the people who worked in both — modest two-story rows on Windsor Place, Sherman Street, Howard Place and Seeley Street, brick and frame, sixteen to twenty feet wide, many of them semi-detached with an alley or a driveway slipped between pairs. There are limestone rows on the blocks nearest the park and a handful of prewar apartment houses along Prospect Park Southwest facing it, and there are postwar co-op buildings out along Fort Hamilton Parkway and the streets the Prospect Expressway cut through in the 1950s. What there is very little of is the wide, deep, high-ceilinged brownstone the rest of the borough gets written about. The houses here are the compact version, and the storage question follows from that.

The plan is honest about what it gives you. A parlor floor with the stair on one side, two or three bedrooms above, a finished basement or a garden-level rental below, and a closet count you can hold in one hand: a coat alcove near the front door, maybe a shallow press on the upper landing, and one two-foot recess per bedroom, sized for a household that owned a winter coat and a Sunday suit. The trim is plainer than a Park Slope row — painted pine, simple casings, an occasional bit of oak on the newel — which is a relief in one way and a constraint in another. Matching profiles is easy. Finding the inches is not. When a bedroom is eleven feet across, every closet you add has to give back more than it takes, and that is a drawing problem before it is a cabinetry problem.

The half-story under the roof is the move that makes these houses work. Almost every one of these rows has a pitched or shallow-mansard roof with an attic behind knee walls — the low triangular runs where the rafters meet the joists, usually reached by a small hatch, usually holding a century of nothing. Opened up properly, that band becomes the best storage in the house: drawer towers set into the knee wall on full-extension runners, hanging on the one wall that reaches full height, seasonal boxes on pull-out carriages that ride out from under the slope instead of being crawled after. The ceiling rakes, so the cabinetry rakes with it, each unit drawn to the actual rafter angle rather than stopped short at a safe height. Done well it takes the pressure off every bedroom below, which is the whole point in a house this size.

Downstairs the work is smaller and more surgical. A bedroom reach-in rebuilt properly — double-hung rods, a drawer bank instead of a floor of shoes, shelving to the ceiling rather than the one shelf and one pole the builder left — routinely doubles what a closet holds without moving a wall. At the back door, which in these houses is the door the family actually uses, a mudroom run for coats, boots, strollers and the bicycles that come out of the basement in April. On the landing, a linen press in the wall stub beside the stair. And in the co-ops along the parkway, where the rooms are postwar and square but the closets are still shallow, a wardrobe wall drawn to the ceiling line and a hall closet reworked into something that earns its footprint. Park Slope is four blocks and a different price per foot away; the work we do there is the same work at a larger scale.

This is where a made-to-measure piece and a configured system part company. Those systems are built on fixed increments and assume a plumb, square, full-height wall, and in a newer building they do respectable work. A frame rowhouse from 1912 offers none of those things — a run can lose half an inch across nine feet, the floors have settled toward the party wall, and a knee-wall attic has no full-height wall to hang a standard panel on at all. When the ceiling rakes, the dimensions have to come off the measured room, which is why we draw and mill every piece to the house. Each project is designed in 3D, milled at our own workshop at 382 Canal Place in Mott Haven, and dry-fit on the bench before it ships, so the install is measured in days. The crew that surveyed the house is the crew that sets it; we have never subcontracted a job, we have worked this way since 2008, and the cabinetry carries a twenty-five-year guarantee. Windsor Terrace is not a historic district, so interior joinery here answers to the house and to nobody else.

Cost follows the room. A rebuilt bedroom reach-in starts around $3,500; a knee-wall attic fitted end to end runs several times that, depending on how much of the slope you use; a full dressing room in a converted top floor reaches into the tens of thousands, and we publish how the pricing works rather than making you ask. Plenty of these houses are still two-family, so we are often drawing two programs at once — an owner's floors and a rental that has to stay simple and hard-wearing. The borough page for Brooklyn collects the neighboring guides. The first conversation is sixty minutes, at the house or at the workshop: $350 flat, credited to your project. Bring the floor plan if you have one, and tell us whether anyone has been up in the attic lately.
