Drawings of residential and commercial buildings in Brisbane and regional Queensland.

The collection contains tracings, drawings, blueprints and linen plans for residential and commercial buildings in Brisbane and regional Queensland. Also includes work of Alexander I Trewern, younger brother of E P Trewern. Includes 38 photographs (20 x 26 cm or smaller), nine oversize photographs (most on paper mounted on board) of buildings by Trewern, including his own house; specifictions for St. Matthew's Anglican Church and the Upper Mt. Gravatt Methodist Church; three envolvopes from the American Face Brick Association with plates for houses; publications relating to houses by G. L. Sutcliffe; and journal cuttings.

Much of the material in this collection was prepared for a series of residences and plans to be published in the Sunday Mail. Little material can be positively identified. Some of these items have numbers on the reverse which appears to signify that these were plans for actual jobs undertaken by Da Costa. A distinct Spanish influence can be discerned in many of the houses. Many of the plans bear the initials A or B, A meaning wooden construction and B denoting brick construction.
