The length of the build process for a design build project can vary depending on the scope and complexity of the project and the preferences of the design build team and the client. In general, however, design-build projects tend to be completed more quickly than traditional design-bid-build projects because the design and construction phases are integrated. Typically, small remodels can take 2-6 months, medium remodels 6-8 months, and new builds 12-18 months.
