The planning applications generally contain two kinds of records:
1. Plans for the structure proposed to be built or altered in drawing, blue or white paper;
2. Letters from the architect or builder submitting the plan and listing the construction materials to the Local Government Board.
The plans are hand drawn and some are coloured with watercolours. They can be complemented by a block plan, which is a sketch, coloured or not, of the property location in the area. The block plan may be in a corner of the same sheet of the main plan. They may be signed or stamped by the architect and are typically marked approved or disapproved by the Local Government Board with a signature and date.
The plans and letters are folded and enclosed in numbered envelopes in ascending order. The envelopes also contain a brief title identifying the type of plan, the requester and if it was approved or not.
After plan 596, inclusive, the Local Government Board began adding a sticker to the back of the plans which was completed with the date the application was submitted, inspected and approved or not.
Some plans in this series predate the timeframe of planning applications as an administrative function.
