Iron frame, with end walls and upper part of side walls in brick; hipped double roof with large slates of diminishing courses and some asbestos sheet replacement. PLAN: double-depth rectangular plan, truncated at S end; 7 bays survive of original 10 bays. EXTERIOR: Single storey elevations originally open to E and W sides with original strips of cast-iron small-paned windows above inserted rendered walling; 4-window N end, with arcade of recessed semi-circular arched windows with glazing bar sashes. INTERIOR: contains 2 trusses with wrought-iron tension members to flat cast-iron ties and braces, supported by an axial row of cast-iron columns, joined to perimeter T -section columns by cast-iron beams and a central valley beam; each of the internal columns has diagonal braces both parallel and at right angles to the trusses; iron laths to slates. HISTORY: originally a 10-bay open structure providing cover each for a pair of saw pits. The internal frame and external walls similar to those used by Edward Holl for the 1826 mast house (Building 26, qv). An example of the experimental iron construction developed by Rennie and Holl and pioneered in the dockyards. An important example of a free-standing iron frame, and forming part of a unique early C19 dockyard.

Description from record TQ 97 NW 1024:
Now office and store, built 1828 to design of William Miller. Iron-framed with end walls and upper part of side wall in brick. Hipped double roof with dimishing slate courses. Rectangular plan, truncated to south: 7 of original 10 bays survive. Outstanding example of experimental iron construction pioneered in dockyard and mill buildings of the period. Ironwork by R & F Salsbury, Dudley. (1)

Used to house saw-pits the building originally had eight bays containing two saw pits each.. The 1864 OS map shows that the north end bays contianing a fire-engine house rather than saw pits but it is not clear if this was originally part of the plan. Also the south end bay had also been partitioned off and used as a converter mould store. The adjancent bay still contained saw pits. The building was probably truncated in the mid-20th century and at the time of survey had recently been used as an engineering store but was currently unused. (2)
