The benefits of building a house using moulded concrete blocks were many. The process would include the ability to manufacture on-site the exact number of blocks that were needed for each house, so the issue of materials shortages would not arise. Additionally, individuality in exterior design could be made by changing the order, design and placement of the type of blocks on each house.
The fireproof properties of concrete were promoted as an advantage, and the ability of using one main building material – concrete – and getting the maximum amount of variation from the same material was an added bonus. In slow times, the small contractor could manufacture blocks and sell them for additional profit.
When completed, houses built with this method – and finished with wood interior and roof construction – were attractive and distinct additions to existing neighbourhoods.
The flexibility of the moulded construction method of the blocks gave the builder an ability to show inventiveness and design by using “specials”. The colour of the concrete itself could be adjusted, allowing for colour differences ranging from the usual warm grey to a near white, giving the impression of marble or a finer stone.
Other ways of adding variety to the building was by using different coloured mortar in the usually half-round convex mortar joints. Mortar could be in the matching warm grey of the concrete blocks, or a distinctive dark grey/black, or even a dark red colour, which could relate to other colours on the house – possibly the paint colour of the sash, or brick used elsewhere on the building.
