Summary for 3300 6TH AVE / Parcel ID 1327300012 / Inv # 0

Historic Name: United Terminals Common Name: Alaskan Copper Works
Style: Modern - International Style, Other - Utilitarian Neighborhood: Duwamish
Built By: Year Built: 1956

Plat: Canal Waterway, Block: 13-16, Lots: All

Although not completely intact and utilitarian in terms of style, this building appears much as it did in an early photo from 1956, when it was first completed. It was built as an office building and, early on, was leased to United Terminals Incorporated. The architect is listed as H. T. Long. The building now houses the Alaska Copper Works, which is housed in several other buildings in the near vicinity.


This is a very simple concrete box with a rectangular plan. The main elevation include  six punched rectangular window openings, each originally fitted with a double light window, (probably a slider). Currently many of the window openings have a mechanical air conditioning unit in place of one of the window panes. An entrance is placed asymmetrically on the façade. It is located to the north of two window openings on the south end. The entrance includes a double door with transom and sidelights, set in aluminum frames. The entrance is also topped by what appears to be an original metal awning, set at an exact 90 degree angle to the façade. Another feature is a fairly hefty, but original roof addition, topped by a brick chimney, set on its north side.
