Quarters A and Quarters B are Federal period houses with later additions. Other houses range in style, from Quarters H, an asymmetrical Gothic Revival building, to Quarters R, a Colonial Revival house built in 1900. Except for Dahlgren Avenue and Parsons Avenue which is one block east of Dahlgren Avenue, the streets in the yard do not follow the layout of city streets. Streets run perpendicular but do not form a grid pattern as most are not through streets. The effect is almost like a maze.
Railroad tracks run through a number of streets adding to the district's industrial character.
There are a number of open spaces besides Leutze Park. The Commandant's Office is located in Montgomery Square. Unfortunately this square is now covered with asphalt as is Trophy Park which was located between the Commandant's Office and the river. South of Sicard Street along the west waterfront is Admiral Willard Park, a triangular area with grass and displays of ordnance surrounded by parking lots. Most of the industrial buildings in the district were built between 1850 and 1919.
