A 20x20 island is a different kind of project than an inline. At about 400 square feet open on every side, there is no back wall to hide behind, so the structure has to work as a piece of architecture: visible from four aisles, balanced from the ceiling down, and built so several trades can sequence cleanly during move-in.
Islands of this size live at the Greenville Convention Center campus, where the TD Convention Center anchors 280,000 square feet of exhibit space and large expos sell island blocks. Those shows generally require a general contractor for booth furnishings, and food-and-beverage on the campus runs through SAVOR Catering by ASM, which holds exclusive distribution rights and requires prior written approval for exhibitor samples. An island with any hospitality element has to plan around that.
Buyers go to a 20x20 when they need command of the floor, controlled hospitality, or enough room for demos and meetings to run at once. The smarter question is not only how the island looks, but what install sequence and what venue approvals it sets in motion.
Execution priorities
- Design for all four sides. An island has no back, so sightlines, branding, and a center anchor have to read from every aisle.
- Resolve structure, hanging sign, and electrical drops before creative is locked, because those decisions drive the install order.
- Sequence flooring, scenic, graphics, and technical installs in the exact order the convention-center floor requires.
- Plan any food, beverage, or hospitality around SAVOR Catering by ASM's exclusive rights and written-approval process on the convention-center campus.
- Build the island for modular reuse so a 400-square-foot footprint can travel to Spartanburg, Anderson, or beyond on the same calendar.
Floor rules that shape a 20x20 island
A 20x20 in a hall like the TD Convention Center is governed by the building before it is governed by the design. Hanging-sign height, rigging points, electrical drop locations, and forklift access all sit inside the venue's published process, and the island gets planned against that.
Venue rules, utility orders, security, and catering vary by property and show organizer, so execution plans are built venue by venue. For the convention center specifically, that means exhibitor-appointed-contractor coordination, floor-plan review, and event-manager alignment, plus the SAVOR food-and-beverage approval step for anything served in the booth.
20x20 island trade show booth planning questions
Why is a 20x20 island harder to plan than an inline?
Because it is open on four sides and usually carries a hanging sign, rigging, and multiple trades. About 400 square feet with no back wall means structure, electrical, and traffic flow get resolved before the creative, and the install runs in a strict sequence.
Do you work at the TD Convention Center?
Yes. The TD Convention Center is the branded name for the main exhibit hall within the Greenville Convention Center campus at 1 Exposition Drive, and it carries the core island-sized floor space. Projects there are planned against its specific floor rules and general-contractor requirement.
How does catering work if our island has hospitality?
On the convention-center campus, SAVOR Catering by ASM holds exclusive food-and-beverage distribution rights and requires prior written approval for exhibitor samples. Any tasting, bar, or catered moment in a 20x20 is planned around that exclusive rather than brought in independently.
Who runs a 20x20 install on-site?
One named show-site lead carries the floor plan and punch list from crates to doors, sequences the trades, and reports up once a day. On an island, that single point of accountability matters because several installs overlap.
How much lead time does a 20x20 need?
Custom islands run best with 16 to 20 weeks. A modular or rental 20x20 takes 10 to 14 weeks. Work inside a month is possible but raises cost and narrows structural and rigging options sharply.
Can a 400-square-foot island travel to another city?
Yes, when it is built for it. Islands are designed for modular reuse unless single-use scenic is required: same structure, swappable graphics, standard crates. A Greenville program that rolls to Spartanburg or out of state on the same calendar gets handled end to end.
What information starts a 20x20 brief?
The show, the venue, the booth number, the dates, whether a hanging sign is allowed, and a budget range. From those, an initial island concept and a realistic cost come back within a few days.
