Four floors, one stair, and a century of beautiful storage debt.

North of Central Park, the brownstone is not a type, it's a civilization: Strivers' Row's McKim flats, Convent Avenue's Romanesque piles, Mount Morris Park's Italianates. Many survived the twentieth century as rooming houses, and the renovation wave restoring them to single-family life inherits both glory — mahogany newels, pier mirrors, pocket doors — and a complete absence of closets, because 1890 dressed out of armoires.

Whole-house projects organize by floor. The parlor floor stays ceremonial: storage there hides in paneled walls and window-seat drawers, profiled to the original wainscot so the room keeps its 1895 face. The bedroom floors take the wardrobe walls — full-height, often a dressing room claimed from the smallest bedroom, which is the single best trade in a four-story house. The garden floor wants the working program: mudroom at the under-stoop door, laundry that folds, sports gear in lockers.

The stair is the spine and its underside is treasure. A brownstone stair descends through four floors, and the triangle below each run — a coat closet's worth per floor — usually holds a water heater's ghost and some paint cans. We build drawer banks shaped to the stringer, deepest drawer at the bottom, and recover what amounts to a small room across the house.

Original fabric rules the detailing. We have color-matched cerused oak to a shellacked 1888 newel, profiled new panel molding from a surviving parlor door, and hung closet fronts on the house's own restored pocket-door hardware. In the landmarked districts — Mount Morris Park, Hamilton Heights — interiors are yours to shape, but the spirit of the house audits everything; work that fights it cheapens both.

Budgets run the spread of the houses themselves: a single bedroom wardrobe wall starts where our pricing essay says reach-ins do; a four-floor program is a season of work and prices like one. Either way the survey comes first — a brownstone that has carried a century of renovations needs its true dimensions on record before anyone's cabinetry pretends otherwise.

We are a Bronx workshop; Harlem is our neighbor, ten minutes down the Harlem River Drive. The trucks are short and the affection is real — come see the floor.
