Better view for comparison...

The materials look nice and I'm sure it'll look great up close, but cuts a pretty grim figure against the rest of the Brooklyn skyline. Bummer!

Bummer indeed... to a discerning eye, just because "it is tall" doesn't automatically make it a great design. Aesthetics and a semblance of imagination in a design should count for some sort of quality besides height.

haha — i could see that.

i guess i don’t have that fear — i think the facade is pretty cool.

too bad about the tower design itself though.

now it looks like a bland office tower.

the base is pretty cool — or at least appropriate.

Alloy secures $500M for “world’s tallest” passive house building
Kayne Anderson, Vistria are providing $495M for energy-efficient Brooklyn project

Developers of what is poised to be the world’s tallest passive house building in the world secured $500 million to get the project off the ground.

Alloy Development on Monday closed on $375 million in loans from Kayne Anderson Real Estate for One Third Avenue, a 583-unit tower planned for Downtown Brooklyn. Additionally, Vistria Group, in its first ground-up development, is infusing $120 million in equity and taking a majority stake in the project as a limited partner. Alloy, as general partner, will continue to lead development and is kicking in $40 million.

According to Alloy, the 730-foot tower is slated to be the world’s tallest built to passive house standards, a design method aimed at cutting energy costs through extreme insulation. The project is the second phase of “Alloy Block,” which includes the city’s first all-electric skyscraper at 505 State Street and two public schools (also passive house) at 489 State Street.

One Third Avenue will include 143 affordable housing units, with monthly rents starting at $1,023 per month. These apartments will be reserved for tenants earning, on average, 60 percent of the area median income.

Residential space will span the 11th through 60th floors, and the tower’s podium will include 60,000 square feet of office space. Two buildings constructed in the 1800s on State Street and Schermerhorn Street will also be incorporated into the development, and house 30,000 square feet of retail space.
