Except for very few cases, built improvements on the land have a lifespan. Ultimately, the improvements on the land are wasted, either economically, physically, or functionally. When this happens, the land will be redeveloped. Theoretically, it will be redeveloped into its Highest and Best Use.
This process is described as the Real Estate Lifecycle.

All residential development has one thing in common, land. You cannot build a building without having somewhere to put it! The first stage of development is to identify a parcel of land.
Rather than starting with a vacant parcel of land, most development involves taking a parcel of land with existing improvements such as an office building or industrial building, then demolishing it and developing a new building on the land. Typically, developers will look for existing buildings where the land is not being utilised at its Highest and Best Use.
The developer assembles a team of development professionals to plan what type of development is to be delivered. This consists of several core activities:
The building will perform the function for which it is designed. The longer that this process can be extended, the greater the return relative to the initial cost. Eventually the improvements on the land will become obsolete; this could occur for several reasons, including:
For whatever reason, other than in some unique circumstances, this process will take place and the development cycle will begin again.
