ESB Design + Build Favicon

ESB Design+Build is an experienced Arizona general contractor, prefab builder, modular building manufacturer, and woman-owned small business. Unlike typical modular builders, we construct completely custom buildings in a fraction of the time and cost of conventional construction. Our most popular commercial construction is our slab-on-grade, floorless steel-frame modular buildings that look anything but modular.

ESB Design+Build is licensed, bonded and insured to perform all work associated with the site and building for your building project. We offer time savings, reduced costs, reduced site disturbance, higher quality, and greater quality control, among other advantages.

We’ve mastered designing to your budget and value engineering, and we take pride in building top quality modular buildings while providing enjoyable, personal service.

Types of projects ESB Design + Build works on

We have decades of experience building facilities for education, child care, animal care, healthcare, government, administration, religious, and private business uses. Our most popular offering is our slab-on-grade, steel frame modular building. ESB also performs planning and design services for our building projects; however, this typically is not a service that we offer separately from performing the construction phase. If you already have, or if you would like to use another design contractor, we are happy to work with whoever you choose.

As a general note, if you choose ESB for planning and design – turnkey construction – you get your best value we can offer!

What will my building cost?

Since each building ESB erects is custom designed, we do not have a catalog from which we can immediately tell you a price estimate. We take great care in pricing projects, because we know it is important to avoid surprises and cost overruns. Please call us, or you can fill out the Contact Form or Project Inquiry Form on our website and we will call you! We will never sell or give away your information to anyone – we solely use it to return your correspondence.

How long will my building project take?

The construction timeline we would devise for you depends on a few things. First, it depends on the size of the building or project. Second, what has been completed so far? Third, when is your target date for occupying your building(s)? Finally, we will have to fit your project into our operations. The first three items can be provided in the Project Inquiry Form that you can submit online, or you can give us a call! Our staff would be happy to help you understand how soon a project can be completed and steps to move forward. For more information about what working with ESB looks like, please see our Process page.
