New York City’s first new mass timber buildings in nearly a century are on the rise in Williamsburg, and the first of the two buildings is expected to wrap in June this year, according to 6sqft.

Field Condition recently stopped by the two construction sites; the three-story structure at 320 Wythe Avenue has topped out and is now covered in tarp. Meanwhile foundation work is underway on the five-story building at 360 Wythe Avenue, which will be complete later this year.

The project, which is developed and designed by Flank, was first announced in November last year. The building at 320 Wythe Avenue will have 4,000 square feet of retail on the ground floor, and 11,000 square feet of office space above that. At 360 Wythe, there will be 18,000 square feet of retail, 46,000 square feet of office space, and 27 apartments.

For the project, Flank is using nail-laminated timber that is made from Canadian black spruce trees, according to the Commercial Observer. This particular timber is specially created and treated so that it’s fire-resistent and more dense. Once the wooden frames are complete, the building will be clad in brick, to make it blend in better with the commercial and industrial buildings in the neighborhood.
