210 units of new housing will rise on the site of the former Brooklyn Heights Railroad Co. trolley barn at Manhattan between Box and Clay. The building (Crain’s says it’s a “tower”, but the R6A puts a 7-story cap on the whole thing) will have half the units set aside middle- and low-income residents, with the other half being market rate. I’m not sure if the income splits are exactly the same, but this mixed affordable/market-rate development scenario is a very similar set up to 11 Broadway.
