More about Bank Flats

“When you select Build SMART to supply your next project, you’re not settling for just another producer of prefabricated ‘Wall Panels.’ We do much more than cut and nail your framing together. Build SMART is an off-site extension of your entire build team.”

– David Boyer, President/CEO
