The International Builders' Show, rebuilt every year
A trade show site is not a website that gets redesigned every few years. It is a product with a fixed annual deadline, an audience that turns over between editions, and tooling thousands of exhibitors depend on. We build the registration site, the microsites and the rest of the digital experience for the National Association of Home Builders, and have done for about two decades.

The problem
What they were dealing with
Most websites are rebuilt when they start to feel old. A trade show site is rebuilt because the show happens again.
The International Builders' Show is the largest annual light construction show in the world. Every edition brings a new floor plan, a new education program, a new set of exhibitors and a new deadline that does not move. The site has to be ready before registration opens, and it has to carry three audiences at once: attendees planning which sessions and booths to visit, exhibitors buying and managing booth space, and the association's own staff keeping thousands of records current without calling a developer.
The association represents more than 140,000 members, and the show has to serve all of them at once — builders and remodelers, multifamily developers, designers, exhibitors, media, and international delegations, each arriving with different goals. The content those audiences need is spread across four separate systems, none of which was built to hand a visitor a single schedule. Combining them into one experience, without leaving staff to reconcile them by hand, is most of the work.
The trap in work like this is that an annual rebuild quietly becomes an annual rewrite. Each year's site is built to that year's brief, the tooling underneath gets forked rather than extended, and by year five nobody can change the exhibitor flow without breaking the search. The brief is never just "build this year's site". It is "build this year's site without making next year's harder".
Constraints
What made it hard, and what we did about it
- Challenge
- A deadline fixed by an event, not a project plan
- What we did
- Run the site as a product with a yearly release, so the annual work is scoped against a stable platform rather than a blank page.
- Result
- An unbroken run of 23 consecutive shows on this site. The 2027 show's site shipped in September 2026, seven months after the 2026 show closed.
- Challenge
- Thousands of exhibitors needing to transact, not just read
- What we did
- Build exhibitor application and booth management into the site — purchasing space, booth size and location, payment options and contracts.
- Result
- Exhibitors manage their own listings and bookings rather than routing changes through association staff.
- Challenge
- Attendees planning at a desk, then navigating on foot
- What we did
- Rebuild the Show Planner responsively and ship a mobile view aimed at people already on the floor.
- Result
- The same plan works before the show and during it, on whatever device an attendee has with them.
- Challenge
- Twenty years of accumulated tooling
- What we did
- Periodically overhaul the back end rather than layering another year on top — most recently for the 2024 show.
- Result
- The platform is still the one being extended, not one being worked around.
How it ran
The sequence
Treat the show site as one long-lived product with an annual release, not as a series of projects that happen to share a name.
The scope
The whole digital experience, not a brochure site
Registration, the microsites that carry individual programs and awards, exhibitor application and booth management, education and event search, the show planner, and the content tools NAHB staff run it all with. The show's digital presence is not a site with systems bolted to it; it is the systems, with a site over the top.
Every year
Ship the edition
A new design and content structure for the coming show, built against a deadline set by the event rather than by the project. The 2012 site introduced tools for community sponsorships, special events and featured exhibitors. The 2013 site expanded search across exhibitors, events and education, and added managed virtual booths.
As the audience moved
Follow attendees onto the show floor
A mobile version of the 2013 site focused on what matters to someone already at the show, including a Happening Now view of activities underway. The Show Planner was rebuilt in 2015 so attendees could track education sessions, events and exhibitors from a phone while walking the floor, rather than planning only in advance.
Recurring
Give the work back to the association
Exhibitor application and booth management, so exhibitors buy space and manage their own listings. Content tools so NAHB staff manage the homepage, education and event data themselves. Each year the share of the site that needs a developer gets smaller.
2020
Build for a show that might change shape
The focus for that year's site was a flexible design that could absorb changes to the content and format of the show as the pandemic altered how the industry met. Performance and accessibility were worked on at the same time.
2023
Overhaul what is underneath
A complete rebuild of the back-end content management and admin tools for faster performance and easier maintenance — the periodic repayment that keeps an annual release cadence from accruing debt indefinitely.

The 2026 show closed on February 19 with more than 75,000 attendees. That is the load the site carries: every one of them planning a schedule, finding a booth, or booking a session against a deadline set by the event.
The show it carries is the largest annual light construction event in the world: more than 78,000 registrants and industry professionals from over 100 countries, more than 1,700 companies and brands, and over 120 education sessions in a single program. Twenty-three consecutive shows have gone out on this site.
The relationship runs wider than the show. It has taken in the association's main site search, a mobile site, e-commerce, the Multifamily Pillars of the Industry awards program, The New American Home, and in 2024 the National Housing Center.
What the client gained
Beyond the numbers
A release cadence, not a rescue cycle
The site has not needed to be started again from scratch. Each year extends the platform rather than replacing it.
Work that moved to the association
Exhibitor self-service and staff content tools mean the parts of the show that change most often are changed by the people closest to them.
Institutional memory
Two decades on one system means the people building this year's edition already know why last year's decisions were made. That is the part a procurement cycle cannot buy.
How the site works
One site, several audiences, four source systems
The site runs on Lighthouse, our own content platform, so association staff manage it themselves, with the show's other systems tied in behind it. That is what lets the site be rebranded and extended each year as the show adds programs and on-site experiences, rather than rebuilt from the beginning.
Centrals pages, one per industry segment.
Staff pick a topic — Remodeling, Multifamily, Design — and the page assembles itself, pulling matching education sessions, courses from the association's own database and CMS-managed events onto one schedule. A new segment is configuration rather than custom development, so the pattern carries from one show year to the next.
Exhibitor self-service.
Exhibitors manage their own profile pages through a dedicated portal, which keeps more than 1,190 listings current while association staff keep oversight of what is published.
Registration for international delegations.
Dedicated tools handle registration for the international groups that attend the show.
