Restoration is defined as the process of reestablishing a self-sustaining habitat that closely resembles a natural condition in terms of structure and function. In simpler words, building restoration is a process of renewal and refurbishment of the fabric of a building.
This covers a wide span of activities, from cleaning of interior or exterior of a building, removal of layers of paint and cleaning and repair of the exterior walls.There are three main types of restoration:
Building Cleaning – This is mostly cleaning the external facade of a building.
Major Repair – This is done when stonework affected by acid rain and other pollutants, and which has weathered or decayed to a structurally unsound or aesthetically displeasing condition.
Rebuilding – Rebuilding to replace severely damaged or missing parts of a building. Here, in all cases, a balance is to be struck between recreation of the original building using materials and techniques similar to the original construction.
Renovation is the ability to restore existing old structure to an earlier condition, but in better structural and aesthetic beauty, as by repairing or remodeling the existing structure to perfection. In simpler words, to renovate means to impart new vigor or to revive its hidden beauty.
