After several architects were unable to meet expectations for the building's façade, Yong assumed responsibility for the interior design and architectural concept.

[4] According to Yong, he immediately had an inspiration and sketched the iconic lion head, the pyramid and roughly how the building facade would look like after meeting with Sunway's chairman, Tan Sri Dr. Jeffrey Cheah.

ft. From October to December 2011, the 'Canopy Walk Extension Phase 3' project improved the northeast dining zone, now known as Oasis Boulevard East.

The lower ground section, 'Oasis Avenue' (which replaced the former AEON supermarket) currently houses new dining establishments such as DIN by Din Tai Fung, TORII Teppanyaki, Dandy, VCR, Burger King, and The Coffee Bean and Tea Leaf, as well as the Jaya Grocer anchor tenant (the supermarket was previously located at the basement level).

The area is directly linked to the shopping mall through multiple entrances, elevators, and escalators, providing seamless access.

The Canopy Walk links the mall directly to most nearby landmarks, thus eliminating the need for pedestrians to cross the road or drive to get to places in the city.

The mall is also directly accessible from Sunway Pyramid Hotel and Sunway Resort Hotel via The Link, a retail and dining zone completed in 2022 which contains esteemed restaurant franchises such as Din Tai Fung and Haidilao Hot Pot (which replaced the area formerly occupied by Taste Enclave, a food court[17]).
