These blueprints, drawn by the Wellington architect W. P. Maule, show proposed modifications to the Palmerston North Chief Post Office building. These changes included the addition of a power house, relocation of doors and fireplaces and installation of steel columns, beams and girders. The plans were prepared in 1914, but it is unclear when the work was completed. A report in the Manawatū Standard stated: "The plans for the proposed additions have been prepared, and the work will be put in hand immediately." However, it was also "anticipated that owing to the war and the consequent difficulty in procuring the necessary materials" there may be delays in realising these developments (1 March 1916, p.5).

The original plans are held by Archives New Zealand as part of the Public Works Department - Maps and plans (Series / 22541).

This plan is for the commercial premises of Brick & Pipes Ltd in Featherston Street. The brick building featured an office and storeroom near the street, with a storeroom and garage behind. Today only a portion of the front part of the original building remains. This is owned and maintained by the Hoffman Kiln Trust.

Brick and Pipes Limited formed in 1919 and ceased trading in 1983.
