About The Vendor:

With over 30 years in our industry, Arizona-based Eastern Style Builders, Inc. dba ESB Design+Build is an experienced design-build general contractor, custom offsite and modular builder and woman-owned small business.

To us, modular is not a type of building; it is a way of building. We take pride in our unique construction technology; it is significantly faster, safer, more sustainable, and more efficient, improves quality control and is more cost effective.

The reason our construction technology is greener, with fewer carbon emissions, is the same reason we are able to save you time and money; it all boils down to reduced waste. ESB's simultaneous construction reduces time and labor on site, which cuts the individual costs of being on site, such as travel time, renting temporary toilets, security, temporary fencing, among other things. Framing your building in our factory reduces the amount of work needed for staging materials on site and lessens risk of loss due to theft or inclement weather. The result of ESB's work - your building - is a less expensive, stronger, higher quality structure completed in a fraction of the time.
