They call it “The Stack”

The Stack at 1133 Melville in Vancouver’s unique exterior design features 4 four stacked boxes throughout the building, making it stand out amongst a crowd of surrounding skyscrapers.

RWC Systems was selected to construct the exterior and interior walls and ceilings of this building. This included specialty exterior soffits assemblies, a two-floor lobby and interior acoustical ceilings for this commercial high-rise. This project used a significant amount of custom and alternative materials.

Ledcor selected RWC Systems because of its reputation for delivering complex, large-scale projects with a high degree of quality and due to RWC’s previous projects with Ledcor. 


The design for 1133 Melville featured an extension of the building at a high floor. This meant the soffits that needed to be installed under this floor needed to be extremely durable as access to these soffits was almost impossible post-construction.

  • Exterior Soffit Installation

    The building’s rotational design created a challenge as the floor of the building shifts on floors 5, 11, 18 and 26. To install the soffits underneath these floors, a series of scaffoldings needed to be constructed underneath. This posed a challenge on the 26th floor as the scaffolding in that area was extremely high.

  • Custom, durable, corrosion-resistant materials

    Aluminum’s corrosion resistance made it the ideal choice over steel stud framing materials. This material change decision removed the need for future maintenance checks while lasting the lifetime of the building. This also meant that access to inspect these areas were not required.

  • Rooftop Patio

    The stack has an exceptional rooftop for all its tenants to enjoy. A significant amount of scaffolding was needed to frame large panels at the peak of the building’s rooftop core. Along with scaffolding, high-end acoustic ceilings were created at the stairwell entrance of the rooftop.

  • Two-Floor Lobby

    The two-floor lobby was constructed using high-end finishes and specialty installation drywall products in conference rooms for sound deadening. Once the installation was complete, a layer of specialty paint was applied to give off a fine textured appearance on the conference room ceilings.
