Changi Airport’s upcoming terminal’s first phase is set to be completed mid-2030s and will bring together Singapore Airlines and Scoot under one roof
Changi Airport has officially begun construction on Terminal 5 (T5), marking its most ambitious expansion to date and setting a new benchmark for sustainable, future-ready air travel.
The groundbreaking ceremony, officiated by Prime Minister Lawrence Wong on May 14 at the Changi East site, signals the start of a decade-long project that will reshape Singapore’s aviation landscape.

The new terminal will be built in two phases, with the first phase scheduled for completion in the mid-2030s and set to handle about 50 million passengers a year. T5’s design will draw inspiration from the nation’s lush landscapes and urban sophistication, with natural light filtering through public spaces and vertical gardens in the baggage hall. The upcoming terminal will also be a Green Mark Platinum Super Low Energy Building and powered by clean energy.

First announced in 2013, the T5 project was paused for two years during the Covid-19 pandemic. Its design was subsequently revised to address post-pandemic travel needs, including sub-terminals and contactless touchpoint systems.
One of the key milestones upon T5 opening is the consolidation of Singapore Airlines (SIA) and its budget arm Scoot under one roof for the first time. Currently, the airline operates across three terminals.
By bringing together their operations, the SIA Group aims to streamline processes and enhance operational synergies. This includes check-in and baggage handling to aircraft turnaround and passenger transfers.
The project is part of the broader Changi East development, which spans 1,080 hectares and includes a new urban district and industrial zone, further reinforcing Singapore’s status as a global air hub.
