Breaking away from conventional rectangular shed geometries, the Sphere 150ft Round Marquee is an architectural masterpiece featuring a 150-foot diameter radial steel dome. Engineered as an iconic circular conservatory and wedding rotunda, the building provides 17,671 sq ft of 100% column-free space with a majestic central lantern skylight and concentric perimeter glazing.
Radial Portal Frame & Compression Ring
The dome structure consists of 16 radial tapered steel arches converging at a central 12-foot diameter heavy-wall structural steel compression ring. This geometric arrangement balances gravity and lateral wind loads symmetrically, eliminating the need for massive tie-rods while creating an awe-inspiring ceiling vista.
Complete IFC Stamped Drawing Set & 3D WebGL Portal
Fusion Developers delivered a comprehensive Issued for Construction (IFC) documentation set: AR-101 (Concentric Seating & Layout Plan), AR-102 (Elevations), AR-103 (Cross Sections), AR-104 (Architectural Details), S-001 (Structural GA Framing), and M-001 (Radial MEP Layouts). The project also features an interactive 3D WebGL digital twin enabling clients to inspect the structure from any perspective.
