The Sarawak Energy Berhad (SEB) Headquarters by Jurubina Unireka is a 9-storey sustainable office complex situated on a 4.4-acre site within the Isthmus Master Plan. Designed as a low-energy building and later upgraded to achieve a Certified Green Building Index (GBI) rating, it accommodates 1,500 occupants and integrates innovative environmental strategies such as a central atrium, photovoltaic panels, and rainwater harvesting. The building’s facilities range from offices, meeting and executive spaces to public amenities including a cafeteria, exhibition area, and landscaped roof garden.

A run-down waterfront shop-lot on the embankment of the Miri River was given a new lease of life as corporate offices by James Sie & Associates.
