Houseplans, The House Plan Shop and The House Designers are good sources for simple house plans. Each of these companies has websites that offer customizable design and pricing options.
All three sites allow visitors to customize house plans by square footage and architectural style. Houseplans includes options by structure type and desired price range. The Houseplan Shop customizes according to number of levels, bedrooms and bathrooms. The House Designers includes these search filters plus options for width, depth and garage preference.
Small house plans are typically designs for easily constructed homes of less than 2,000 square feet of living area. Ideally a simple house plan provides a comfortable home that requires a minimal monthly mortgage.
