Plat: South Seattle Addition, Block: 9, Lots: 1-6

This very altered wood frame shop building, whose unofficial address is 4045 7th Avenue South, predates February 2, 1964. Drawings from that date indicate that the building already existed. Like other neighbors on the same parcel, it may actually date from as early as 1906, although this is not at all certain and, if so, the building has been seriously altered. A photo from the 1930s indicates that at that time, the main façade included several double-hung windows. Based on the 1964 drawings by consulting engineer Sigmund Ivarsson, at that time, new ceiling joists were added to beef up the ceiling just below the trusses, as well as solid blocking at supports. At that time, the building was owned by the Seattle Brass Company, which owned other buildings in the vicinity.


 This is a simple frame shop building located slightly south of the southwest corner of 7th Avenue and Andover St. Its central portion is two stories in height and topped by a gable roof over repeated trusses. There is also an additional shed roof to each side of this central space. The exterior of the building is clad in wood. There is little fenestration on the main façade along 7th Avenue South. Currently, there is one window on the north side of the façade. There is a service entry with a sliding wood door on an overhead track, as well as a second service doorway. The north wall adjoins a brick building. The south wall is mostly obscured by a variety of containers and other objects, but appears to have several window openings.
