ARC 380 is a freehold, commercially zoned 16-storey mixed-use development completed in 2018. Retail and F&B occupy Level 1, offices span Levels 5 to 16, and two dedicated levels of lifestyle facilities sit on the 4th-storey Sky Terrace and the 17th-storey Roof Terrace. Cantilevered sky terraces feature on every office floor except Level 5. This page summarises the key technical attributes of Arc 380 Jalan Besar; for layouts see the floor plan, and for the grounds see the site plan.

High-performance, low-emissivity double-glazed curtain-wall panels minimise solar heat and noise for an optimal working environment. Full-height glass offers panoramic Kallang Basin and CBD views with maximum daylight, and the column-free, flexible layout makes it easy to combine multiple units. Every unit has an individual fully fitted bathroom with shower — suitable as an End-of-Trip facility — and there is a common accessible toilet on each office level.
Arc 380 Office is served by an efficient building security system with CCTV monitoring cameras on every floor, a state-of-the-art building automation system, and effective control and monitoring of building M&E services. A grand vehicular drop-off along Jalan Besar leads into a marble-walled office lobby equipped with a turnstile access-card system, concierge services and a visitor-management system.
Parking provision comprises 83 car park lots, 18 bicycle lots, 16 motorcycle lots and 2 accessible lots.
