This interior architecture project reimagines an 1875SF conjoined ‘corner APT’ within a repurposed 1911 NYC Factory Building overlooking Madison Square Park. Our client discovered this ‘diamond in the rough’ down the street which was perfectly suited for their extraordinarily eclectic ART and Furniture collection. Our design approach, as always, was to ‘maximize space within constraints’, whilst ‘pushing the envelope’ where possible and impossible are in equilibrium. Here, that meant celebrating the ‘conjoined-corner-APT-ness’ of the found condition by dissolving most interior walls to create ‘one corner room’ amplifying the ‘abundant diagonal light and views’, NE to Madison square Park and north, east, SE to water towers. A recent glass pencil tower (due north) perfectly reflects south sun deep into ‘the room’ in wintertime. The kitchen was divorced from plumbing stack, with its ‘kitchen island waste and vent’ set at absolute limit within shallow existing floor. Private bedroom / bath is tucked behind a split-curve shelf-wall, per Client’s absolute requirement for ‘not sleeping in the living room.’ Irregular factory-rehab geometries and mechanicals were absorbed into a continuous, slightly rotated corner bench all around ‘the room’: seat, hearth, hidden storage, kitchen counter, desk. Custom perforated details, pencil-line light tracks, and celadon-dusted structural frames extend Manhattan Grid and Broadway Diagonal inside and thru ‘the corner APT.’ Privacy glass partitions / folded clerestory screen, and back-painted-glass columns further multiply light, views and connection to ‘the urban rooms beyond.’ The result: a lived experience deeply tied to site, history, and discovery – continuing an upcycling of Flatiron Heritage.
