This past Saturday, IEC & WhiteSpace Architects collaborated for the 21st Annual CANstruction Honolulu. It was a blast working alongside teams from across the island to transform thousands of canned goods into incredible structures at the Central Pacific Bank atrium, all to support the Hawai‘i Foodbank .

In honor of AIA Hawaii’s 100th anniversary, this year’s theme, “CANtennial: Designs of the Decades,” challenged us to bring history to life. Our giant retro roller skate build embraced the nostalgic, high-energy spirit of the 1980s.

The structures are officially open for public viewing at the CPB Downtown Branch! Stop by this week to check out the builds in person, support the cause, and vote for your favorite sculpture.
