Cornerstone Buildings 3D builder rebuild
Cornerstone Buildings
The challenge
Cornerstone's customers design and price their own sheds, garages and outbuildings through a 3D builder before ordering. The tool was built on legacy .NET Framework with full-page postbacks, which made every configuration change feel sluggish and made it increasingly hard to maintain across their four regional storefronts.
What we built
We rebuilt the 3D builder from the ground up as a React application, keeping their existing product API as the source of truth and redesigning the data-loading layer around it. The rebuild was rolled out region by region over six months with no downtime to any live storefront.
Results
- Product data now loads in 1.2 seconds, replacing the postback-driven .NET frontend
- Rolled out across all four regions (US, Canada, UK, Germany) with zero storefront downtime
- Full migration delivered in 6 months
