How does the cost of flagstone compare to other paving materials?
In general , an entrance or patio constructed of natural flagstone on concrete costs more than the same design built using interlocking brick, or concrete pavers, usually about 30%-40% more. In some instances the price gap closes, such as when there are many steps required. Interlocking-type pavers require walls to be built to create steps and in that situation, the price can be quite close.
