Every residential house construction starts with what is called a house plan or a blueprint. This is a set of drawings that acts as a kind of manual for building the structure. It helps to provide direction for construction workers and specify how the structure should be built.
A typical house plan contains of sub-plans that show each section or part of the house. This include plans such as the foundation, floor, roof and cross-sectional areas. It depicts the front and rear perspectives and elevations as well as show other important features of the structure.
All these includes where walls should be positioned and their dimensions. It tells where windows and doors as well as the various systems around the house should be located.
No house can be built without a blueprint. Attempting to do so will only result in a waste of time and resources. This is because there will be several errors and a need to chop and change the structure each time. A good house plan helps to minimize change to a building or avoid it altogether.
