Construction of type-planned houses began in Finland in the 1920’s. In addition to the building plan, the builders were given a simple job description and building material calculations, so houses were fairly easy to build. After the wars, the most common newly built house was a 1½ storey, with board-on-board cladding. There were many designs, but they were very similar to each other.
In addition to the house plan, the card image includes a saw, a wooden folding ruler, a carpenter’s pen, a bricklayer’s rectangle, a hammer and nails.
