The prolific and talented Brooklyn architect Montrose Morris was known for designing some of the first multi-unit apartment buildings in the borough. This is one of them, at 109 South 9th Street. Built in 1890, the Williamsburg building is decorated with stone, brick and terra cotta alongside oversized, bracketed cornices. Inside is a massive, four-story space with nine bedrooms and eight bathrooms. To make the whole building look good, it’s going to require a big renovation from any buyer.
