This is a row of townhouses built in 1910 by the Burns Brothers, five brothers who also built the Burns Brothers Carriage Factory on Green Street in the 1890s and other buildings in town during the first decade of the 20th century.

The buildings were framed using a method known as balloon framing, which means there are no interior bearing walls—all the bearing weight is on the exterior walls. The exterior is a distinctive textured concrete block manufactured in Havre de Grace. The plant that produced the blocks closed in 1913.

The Burns brothers built many such houses during this same time period. Similar houses exist at 566-568 and the 700 block of Green Street, and in at the 600 block of Fountain Street.
