FreeWoodWorkingPlan.com provides a long list of free, downloadable kitchen island building plans, as of June 2015. A variety of styles and types are available, including angled islands, rustic islands and butcher block islands. Kitchen island plans range from basic, easy-to-build designs, to complex plans with multiple island features.
Alternatively, Build-Basic.com provides in-depth, step-by-step instructions for building a kitchen island.
Pre-made kitchen islands can be expensive, as the cost often includes delivery and installation fees. In contrast, self-built kitchen islands can be much cheaper, because materials are relatively inexpensive and most homeowners already have the necessary tools for building and installation.
