Tetra came into being in 1996 when four young architects, Derijanto Gani, Fritz Simatupang, Priliani and Reggy Widjaya were moved by an idealism to transform their know-how into creativity, beauty and functionality. Over the years Tetra has consistently demonstrated professionalism in accomplishing its assignments and transforming concept into reality. The Company had only six people to start with but this number has increased close to a hundred, to include professionals like architects, interior designers, civil engineers, mechanical and electrical engineers.

It is our ongoing commitment to make Tetra a professional, solid and efficient organization able to think global and act local. Prestigious projects like Telkomsel Head Office, Jakarta Financial Center Office Building, Centra Prima Bahari Head Office of GKBI Building, PT Sinar Rasa Kencana Head Office, Aqua Office and Main Office at Central Pertiwi Bahari, Lampung, Cyber 2 Office Building, Institution for Underprivileged Children by The United Nations-World Food Programme, Philips Cellular Center Indonesia, City Development Project of Essaouira Waterfront City - Morroco North Africa ( Development Concept and City Planning ), Project Plan of Mekar Sari Fruit Garden, Malioboro Hotel & Spa, General Hospital Omni International and Bangka Toboali Mosque is a manifestation of our commitment to play a significant role in the architectural society. Tetra has also taken part in a number of competitions both at home and abroad.
