Florida House Plans: The quintessential coastal Floridian house plan is derived from Spanish house plans and/or Mediterranean house plans. The massing in Florida house plans is bold and noble, and often includes a two-story entry flanked by columns. Low-slung rooflines clad with red-clay tiles are common, as is a stucco exterior. The interior is open and unhindered by walls, which allows for good air circulation. The "footprint" of Florida house plans often focuses on the backyard area, which usually includes a terrace, lanai, deck or patio that borders a pool. Exotic, elegant and energy-wise, coastal Floridian house plans boast a popularity that hasn't waned for decades.
