The Annex Building, located within the CSMT Heritage Precinct, reflects the historic architectural character of the area through its original façade, proportions, and ornamental detailing. The project involves systematic recording and conservation of the structure to safeguard its historic fabric while allowing it to remain actively used. Guided by sustainable heritage conservation principles, the approach prioritizes the retention of existing materials and sensitive integration of necessary interventions. The initiative contributes to the long-term preservation and holistic development of the heritage precinct, reinforcing its cultural and architectural significance.
