A structurally glazed two-storey front on Frost Street and a curved ribbon storefront on three floors at 2 Bushwick Avenue. North Brooklyn builds in glass.
North Brooklyn builds in glass, and the two Williamsburg projects show the range. 24 Frost Street is a structurally glazed two-storey curtain-wall front — no visible frame on the outside, the glass bonded to the mullions — with Everest windows and an entrance door on a mixed-use building. 2 Bushwick Avenue at the corner of Metropolitan is a continuous curved ribbon storefront and curtain wall on all three floors in a custom grey Alutech finish. Both are corner buildings, both are retail below and residential above, and both wanted the glass to be the architecture.
The rest of the Williamsburg and Greenpoint work is the same building type at smaller scale: a new four- to eight-storey building with a storefront on Bedford, Grand or Manhattan Avenue and aluminum windows above, or a converted loft with big steel-look units. Bushwick adds the warehouse conversions with industrial-style divided lites.
Williamsburg, East Williamsburg, South Williamsburg, Greenpoint, Bushwick, Ridgewood border.
Mostly new construction under DOB with the architect of record; the Greenpoint and Williamsburg waterfront rezonings set the building types. The Greenpoint Historic District and the Fillmore Place district in Williamsburg are Landmarks-reviewed. See curtain wall systems and structural and frameless glass.
Converted lofts and factories along Kent, Wythe and the side streets off Metropolitan: big steel-sash openings, brick-to-brick replacements, and a choice between steel-look aluminium that keeps the industrial line and a modern system that gives up the muntins for glass. Tilt-and-turn in Cortizo or Reynaers is the usual answer, with divided lites where the building is landmarked.
New condos and rentals on the North Side and along the waterfront: window wall, curtain wall, balcony doors and storefront below, usually in one system so the elevation reads as designed — Everest, Alutech or Cortizo fabricated in our shop, as on 24 Frost Street.
Retail and restaurants on Bedford, Grand, Driggs and Metropolitan: storefront replacement with the whole facade in play — the curved ribbon front at 2 Bushwick Avenue is the extreme case — and the hardware and glass a public entrance needs.
Row houses and small multifamily on the South Side and in the Italian and Polish blocks: whole-building replacements on uPVC or American aluminium, and the occasional wood-window restoration where a house is landmarked.
The Williamsburg waterfront is exposed to the East River wind, and the towers along Kent Avenue are designed to pressures that a street-side walk-up never sees. Windows and doors there are specified to the wind load on the drawings, with compression seals rather than sliding brush seals on the upper floors, laminated glass on balconies, and sill pans under every terrace door. On the inland blocks the issue is water rather than wind: the older masonry moves, and a replacement window is only as good as its flashing into the wall.
Survey and photographs; a proposal that names the system, glass and hardware and prices the budget, standard and premium options; shop drawings; DOB and, where the block is landmarked, LPC filings; fabrication in our Staten Island shop; installation by our crews, floor by floor with tenants in place where the building is occupied. Storefront replacements are scheduled around the tenant’s trading hours, often at night. Lead times run three to twelve weeks depending on the line. To start, send photographs of the openings with rough sizes, the address, and the name of the architect, board or manager if there is one; we reply with a range the same week and a survey date.
Yes. 24 Frost Street in Williamsburg is a structurally glazed two-storey curtain wall with no visible exterior frame.
Yes; 2 Bushwick Avenue is a continuous curved ribbon storefront on three floors.
Yes, and we repair them; we tell you which you need.
Yes: brick-to-brick replacement of steel sash in converted factories and lofts, with steel-look aluminium divided lites where the building is landmarked or a modern system where it is not.
Usually: we schedule the swap outside trading hours, often overnight, and keep the opening secured between phases.
