The park block, the mansard roof, and the top-floor suite.

Fort Greene grew up around its hill. When Olmsted and Vaux redrew the park in the 1860s — over the crypt of the Prison Ship Martyrs, later crowned by Stanford White's granite column — the blocks that faced it filled in with the best brownstone Brooklyn was building: Italianate and Neo-Grec rows through the 1870s, a run of French Second Empire houses with mansard roofs and dormered top floors, brick and stone standing shoulder to shoulder down Washington Park, South Portland, Carlton and Adelphi. Much of it has been protected as the Fort Greene Historic District since 1978. The houses carry tall parlor ceilings, plaster medallions and deep window casings, and, in the pattern of their era, almost nowhere to hang a coat.

The renovation most of these houses have already had, or are about to have, is the top-floor primary suite: the old servants' and children's rooms under the roof opened into one owner's floor with a bedroom, a bath, and — if it is planned rather than improvised — a dressing room. That top floor is where we do our best work in Fort Greene. We build furniture-grade casework that stands on the floor and loads the floor rather than the century-old plaster, scribed to walls that have not been plumb since the houses were new, with panel heights taken off the existing door heads. Given a spare corner under the roof, it becomes a proper dressing room with an island that reads as part of the house rather than something set down inside it.

The mansard is the catch, and the opportunity. A Second Empire top floor slopes: the ceiling breaks toward the eaves, the dormers cut the wall into odd widths, and the knee-wall behind the slope is dead space until someone measures it. This is the honest place to say where a made-to-measure shop earns its keep — a boxed catalog system such as California Closets is engineered around square, plumb, full-height openings, and a mansard bedroom offers none of those, so its parts either stop short of the slope or leave the best storage empty. We draw and cut each piece to the wall in front of us, running drawers and hanging into the knee-wall and following the rake of the ceiling, which is the difference between a fitted floor and a room full of gaps. Below the suite, the same logic gives reach-in systems in the secondary bedrooms and a stair-landing press in the half-story of nothing between floors.

Working inside the historic district shapes the brief in a useful way. Landmarks governs the exterior — the cornice line, the stoop, the mansard slates that give these blocks their rhythm — and leaves the interior to you, but the interiors deserve the same restraint, because the medallions, the pier mirrors and the original window trim are the reason these rooms are worth the trouble. We match profiles rather than approximate them and treat original woodwork as something to continue, not cover. If your house still carries its 1870s detail, the pre-war joinery approach is the whole game: read the existing millwork first, then make new work a guest assumes was always there.

Geography helps. Our workshop is in the Bronx — every piece is drawn in 3D, milled in-house at 382 Canal Place in Mott Haven, dry-fit on the bench, then installed by our own crew, never subcontracted. For a house where a family is already living around the renovation, that means short install windows that do not turn the top floor into a construction site for a season, and a single shop standing behind the result: the cabinetry is guaranteed for twenty-five years, and we have done only this since 2008. The designer who measures your suite works down the hall from the people who cut it.

Budgets cover the range these houses ask for. A fitted-out reach-in or a single landing press begins around $3,500; a full top-floor dressing room reaches into the tens of thousands, and we publish how the pricing works before you ask. If you want to see the rest of the borough first, the Brooklyn overview is a good place to start. The first conversation is sixty minutes, at the house or at the workshop, no charge — bring the floor plan, or just the slope of the roof.
