Gigabay — SpaceX Starship Integration Facility, Starbase

Gigabay is the building that turns Starbase from a prototype yard into a production line. Starfactory next door makes the parts; Gigabay stacks, tests and prepares full Starship and Super Heavy vehicles for rollout. The primary structure topped out in August 2026.

Project Scope

About 700,000 sq ft, roughly 380 feet tall, enclosing something on the order of 46.5 million cubic feet, which puts it among the largest industrial structures on Earth by volume. Inside are 24 discrete work cells and cranes rated to 400 US tons, sized for vehicles up to 266 feet. The Texas Department of Licensing and Regulation filing puts the job at $250 million with a July 2025 start and a December 2026 completion, and lists HDR as design firm. No general contractor appears in the public filings; SpaceX self-performs a substantial share of its own construction at Starbase.

Why It Matters

The interesting thing about Gigabay isn’t the size, it’s the type. This isn’t a hangar and it isn’t quite a factory. It’s a fixed-cadence assembly hall for vehicles that are 30 feet in diameter, and that building type essentially doesn’t exist in aerospace at this scale. Twenty-four work cells implies a throughput assumption, not a storage assumption.

SpaceX filings have cited up to 1,000 vehicles a year by the end of the decade. Take that as an aspiration rather than a forecast. But the crane ratings, the cell count and the volume are all real, permitted numbers, and they describe a facility built for a build rate no launch provider has ever attempted. A second Gigabay is planned at Roberts Road in Florida.
