If you’ve ever driven past the Savannah/Hilton Head International Airport, you’ve seen the sprawling footprint of a global giant. It is massive. But tucked away within that complex web of hangars and high-tech labs is Gulfstream Aerospace Corporation Bldg Z, a facility that is a lot more than just another warehouse. It’s where some of the most advanced business jets in the world actually take shape.
Honestly, it’s easy to get lost in the alphabet soup of corporate campuses. Building X, Building Y, Building Z—it sounds like a secret government site. But for the folks in Savannah, Building Z is the heartbeat of a $150 million expansion strategy that has basically redefined how private jets are built.
Why Building Z Is a Big Deal for Savannah
Let’s be real: when most people think of manufacturing, they think of greasy assembly lines and loud, clanking machinery. Building Z is the opposite of that. It’s a 425,000-square-foot behemoth that feels more like a tech laboratory than a factory.
Managed during its construction by the experts at Orr Partners, the facility was designed with one goal: efficiency. You've got about 280,000 square feet of clear-span manufacturing space. That means there are no giant pillars in the middle of the room getting in the way of a wing or a fuselage. It’s wide open. This allows Gulfstream to run two simultaneous production lines for their best-in-class jets.
It’s not just about the planes, though. The building houses 70,000 square feet of office space, paint areas, and a central utility plant. It’s a self-contained ecosystem.
Breaking Down the Specs
- Total Square Footage: Approximately 425,000.
- The Foundation: This is the wild part. The soil in this area is notoriously soft. To keep the building from sinking, engineers had to install nearly 5,000 controlled modulus columns (CMCs) going up to 60 feet deep.
- The Slab: On top of those columns sits a three-foot-thick stone load transfer platform.
- The Purpose: Primarily focused on precision manufacturing and support for next-generation models like the G400, G500, and G600.
The Secret Sauce: Commonality and Robotics
One thing that makes the Gulfstream Aerospace Corporation Bldg Z unique is how they handle different plane models. Usually, a factory is built for one specific type of aircraft. If you want to build a different one, you have to tear everything down and start over.
Gulfstream got smart.
They designed the G400, G500, and G600 with "commonalities." Basically, these planes share enough DNA that the robotic bonding techniques and 3D model designs used in Building Z can be adapted quickly. If demand for the G600 spikes, they can pivot.
Precision is the name of the game here. We are talking about stainless steel trenches lining the floor with infrastructure tolerances within eighths of an inch. If a bolt is off by a hair, the software knows. It’s that level of intense detail that justifies the price tag of a jet that can cost upwards of $70 million.
What Most People Get Wrong About Building Z
People often confuse Building Z with the new Service Center East or the older Building X. While they are all part of the same Savannah family, Building Z is the "maker" space.
While the Service Center East (which just opened and added another 200 jobs) focuses on maintenance and repair—like a high-end Jiffy Lube for billionaires—Building Z is where the "birth" of the aircraft happens. It’s the precision manufacturing hub.
Also, it isn't just a shed. It’s a LEED-certified-adjacent mindset. They’ve invested heavily in energy-efficient lighting and advanced climate control. When you’re dealing with the specialized materials used in a G700 or G800, temperature and humidity aren’t just about comfort; they are about the integrity of the carbon fiber and alloys.
How to Actually Get There (If You Have a Reason To)
You can't just wander in. Security is tight. The address is technically part of the 500 Gulfstream Road complex, but Building Z is specifically located near 104 Airways Ave in Savannah, GA.
If you are a vendor or a new hire, you’ll likely spend a lot of time in the 70,000 square feet of office space attached to the production floor. The transition between the "suits" and the "boots" is almost seamless there.

Actionable Insights for Aviation Pros and Job Seekers
If you're looking to get into the aerospace industry or you're a local resident wondering what all that construction was about, here is what you need to know:
- Watch the G400/G500/G600 lines. Building Z’s future is tied to these specific models. As Gulfstream ramps up deliveries for the G400 (their first "small" jet in two decades), Building Z will be the center of the action.
- Brush up on automation. The days of manual riveting are fading. If you want to work inside Building Z, you need to understand robotic integration and 3D modeling.
- Check the Savannah Technical College pipeline. Gulfstream partners heavily with local schools. If you want a foot in the door of a facility like Building Z, their specialized aviation programs are the fastest route.
- Monitor General Dynamics earnings. Since Gulfstream is a subsidiary of General Dynamics, their quarterly reports often mention capital expenditures. That’s where you’ll hear about the next "Building Z" before it even breaks ground.
Building Z is a testament to the fact that American manufacturing isn't dead—it just got a lot smarter and way more expensive.
