The use of standardized components, such as windows, doors and roof trusses, reduces costs by allowing factory production and eliminating much labor at the building site. Factory-produced components are cheaper because they can be mass produced with specialized tools, the workers shed need not be dismantled (as in a building site), workers can be provided cover from bad weather, heat and light, and expensive skilled labor can be replaced by machines. In addition, the reduction in variety eases the stocking problem, while interchangeable spares make repair jobs cheaper.

Standardization of components can be carried on further by dimensional co-ordination, through a systematic method of relating the size of the components to facilitate their use together. It is based on a module of chosen dimensions, which, in multiples or sub-multiples, provides the required sizes of all components, e.g., bricks, breeze blocks, windows, doors, panels and floor slabs, in a logical progression.

The advantages of dimensional co-ordination (which took a big step forward with metrication) are a reduction in the number of components, the elimination of wasteful cutting, and higher productivity through factory production and quicker assembly on site. The leading Builders in Kerala have made a name for themselves by incorporating concepts and practices that are able to improve productivity to a greater extent.

In recent times the concept of green housing is gaining ground with an increasing number of customers demanding this type of apartments and villas. Thus the construction industry in the state is now racing ahead to match the developments in the developed world.
