How it works?

step 1: Choose a Model

Browse pre-designed, pre-engineered plans — or let us help you pick. Click here to see the floor plans.

step 2: Select Your Finishes

The most exciting part of designing your project is figuring out all of the features, styles, fixtures and color selections that come together to create your home. We begin with a standard selection package which you can customize to reflect your style. Our expert design team works with you to explore the options and upgrades that are available and help you fit it within your budget. We have options available that can provide beautiful features but still keep the costs reasonable. We will walk you through every step of the process, so relax and enjoy!

step 3: Structural Engineering

Once the plans are approved and all changes have been made, they will be submitted to engineering. The state licensed engineer will perform the load calculations, determine the buildings structural requirements and provide the roof framing plan, floor framing plan, truss layout, foundation plan and structural detail (roof load, seismic elements, wind exposure & soil conditions (Geo-tech soils report & topo map must be provided in advance by the customer.) The final foundation detailed plan with footing sizes, widths, stem wall height, etc. will be determined during the engineering process.

step 4: Permitting and Approval

Each project must go through a State Approval Process and a Local Building Department Approval in order to obtain your building permit. (Not required in Utah or Wyoming.) Irontown will handle the modular portion with the State Division, we can also handle your local department if you would prefer. Irontown will also prepare any Rescheck or Title 24 (energy conservation report) that may be required.

step 5: Off-Site Factory Construction

Whew! It may sound overwhelming to finally get to this stage, but a lot of the process happens without you even knowing about it. We have so many details that have to be decided prior to construction so that once production has begun your project can be constructed as quickly as possible. Once construction begins, we will be in constant communication with you on the progress. During construction, we will have inspections and payment draws that will occur and you are welcome to visit the factory any time you wish. We do require a final walk through at the completion in the factory.

step 6: Delivery and On-site Setup

Throughout the factory construction process, your general contractor can be working to prepare your project’s site. Upon factory completion, your modules are shipped to your site and craned into place. Once your in place, all the site work and stitching can be completed in just weeks by your general contractor.
