Where the patio used to be,
the best room in the building
A new high-end Brooklyn condominium needed an amenity that would set the building apart on the market. We took the back patio — twelve weeks of usable space a year — and turned it into a year-round glass room with motorized guillotine windows, sliding glass, and integrated climate. Square footage you can show twice on a listing tour.
Twelve weeks of patio. Twelve months of room.
The condominium itself was already done — modern, light-filled, every floor a clean architectural statement. The back patio was the one piece that didn't pull its weight. In Brooklyn, a backyard runs maybe three months of real use a year. Spring rain ruins furniture. Summer humidity pushes you back inside. Winter snow turns it into storage. The garden stayed beautiful — but only through the kitchen window.
The brief, in one line: turn this patio into a room residents actually use in February — without losing the view or making it look like a sunroom bolted onto a brownstone.
Same square footage. Different building.
This is what the patio looked like the day we walked the site — and what it looks like every weekend now. Same footprint. Same view of the garden. Twelve months of usable room where there used to be three.
Three systems. One continuous interior.
The room had to read as part of the condominium, not an add-on. Three premium systems were layered so the boundary between house and garden could move — wide open in spring, sealed warm in January — without ever looking like a compromise.
Insulated Glass Roof
A structural glass canopy with sealed thermal panels overhead. Rainwater runs through channels routed into the frame, snow loads up and slides off, and the sky is visible from every seat in the room.

Floor-to-ceiling glass that lifts vertically on motorized tracks. Open the room fully to the garden on a clear evening; seal it tight against winter wind. All on a single remote.

Connects the residence to the new room without a doorframe in the way. Slide it open and the two spaces become one continuous interior — no threshold, no draft, no visual break.

Components were fabricated to spec, shipped to site, then installed and tied into the building's electrical and HVAC. A mini-split heat pump runs the climate. Permits filed and finalled. Site swept clean.
See it come to life
From bare patio to glass conservatory — captured on site.
Built once. Built right.
Triple-sealed glazing. Powder-coated structural aluminum. Drainage routed through the frame so rainwater leaves the building, not stains its facade. The mini-split disappears into the corner. The kind of detail that costs a little more on day one and stops costing forever after.
