Unlike the speculative building and existing building markets, the build-to-suit market is driven by a company with facility requirements deriving from a variety of market and business conditions as well as economic factors. Market conditions affecting the decision to build are the lack of availability in the existing building market, (including speculative construction, the cost of land building materials, and the competitive building packages offered by the design-build industry). Business conditions, such as unique business operations which require specific building attributes, consolidation, expansion or relocation of business operations, are also considered when a company determines to build a new facility.
