"ICF homes can be designed in any style, and will accept any traditional finish including vinyl or wood siding, stucco and brick. Because custom angles and curves are easily created, it's simple to build in bows, bays, and radiuses (sic). And ICF systems accomodate any of today's most popular design features, such as tall walls, large openings, long floor spans, and cathedral ceilings."
