With a combined total floor of approximately 31,000 square metres, it is the second largest museum in Southeast Asia. Plus, this world- class museum aims to be the main centre for Borneo Heritage Collection by 2030.

A familiar structure that Borneo Cultures Museum has is its distinct golden arched roof, which complements the architecture of the Sarawak State Legislative Assembly (DUN) building across the Sarawak River. There is also a presence of historical and cultural influences incorporated in the architecture of the museum. The silhouetted panels stacked onto one another is inspired by Sarawak’s traditional motifs of woven rattan mats and songket. Meanwhile, the panel wall claddings are designed in abstract reinterpretation of Sarawak’s weavings that simultaneously refers to museum’s role as the state’s cultural heritage guardian. In the centre of the elevation, glass panels forming the façade allow natural daylight to penetrate into the indoor gallery spaces and brighten up public circulation areas.
