What Replaced Blueprints for Houses?

For many decades, blueprints for houses were used by architects and builders to create a 2-dimensional design for a house. The term blueprint generally refers to the detailed and precise version of the house plan. Some architects still use blueprints, preferring the tradition of technological skill in drawing high-quality blueprints.


Traditional blueprints for houses involved using a centuries-old process which meant exposing a mixture of chemicals to very strong light, converting them to a compound known as Prussian Blue. These blueprints were also printed on a range of materials aside from paper, including linen and imitation vellum.

These traditional methods of making blueprints for houses have all but been eliminated by a range of technologies. The original blueprint was replaced by white-print (blue lines on white paper) in the 1940s, and this process is more easily replicated by modern printing. Computer-aided printing allows the machine to create the perfect blueprint for houses.

Computers have also replaced blueprints for houses through the use of digital design. It is now no longer necessary for architects to print their blueprints for houses onto paper: instead, they can display it through a digital image, which can then be transferred to builders and other designers as required. The term blueprint, however, is still used to refer to this type of image.
