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.
