This is a competition-by-invitation project to replace Changi’s Budget Terminal. DPA partnered with Pascall+Watson from UK. The terminal is envisioned by Changi to be a boutique terminal with an interior ambience similar to the other 3 terminals. Changi wants it to be part of the Changi Experience which is stress-free, personalized, people-focused and efficient. The design brief is very retail-focused where Changi derives a large chunk of income. The brief required optimum operational cost savings such as a single passport control and security zone while not sacrificing quality. The brief specified in detail areas and what they envision as a smart premium terminal.
DPI’s proposal is based on a structural grid of 18/36m which is a function of the optimum distance between check-in counters. The large spans mean that there are fewer columns and therefore more visibility across large expanses of space. The column design is a tree-structure that branches out to support a square roof module similar to the modular arrangement that has been done at Stansted Airport, UK. This tree structure differs from Terminal 3 which is a post and truss structure
The circulation is carefully planned so that passengers have to pass all the main retail frontages on their departure journey. The style of the architecture took inspiration from the rain forest. The columns are fluted and gently twisted to evoke sinuous trunks and the roof filters the daylight through carefully positioned panel leaves. The architectural expression is both grand and bold, light and airy.
