Missouri House Plans collection includes floor plans purchased for construction in Missouri within the past 12 months and house plans created by Missouri architects and designers. Please note that some locations may require specific engineering and/or local code adoptions. Be sure to check with your contractor or local building authority to see what is required for your area. If you find a home design that's almost perfect, but not quite, call 1-800-913-2350. Our house plans can be modified to fit your lot or unique needs.
