About Us
With a track record of more than four decades in the industry, ONG&ONG has earned an unparalleled reputation for integrating skilled architecture, clever interior design, creative environmental branding and sensitive landscape design. Paramount to our success lies in our insistence on servicing our clients with creativity, excellence and commitment. We continually strive to uphold our mission to be the designer of our age – a premier design practice both locally and in the region. Currently operating in twelve cities, we are managing projects in 18 countries spread over three continents.

Partnering our clients in their race to the top, ONG&ONG now offers a complete 360º solution – i.e. a parcelled cross-discipline integrated solution, encompassing all aspects of the construction business. We offer a three-pronged 360º solution; namely 360º Design + 360º Engineering + 360º Management. 360º Design encompasses urban planning, architecture, landscape, interiors and environmental branding (graphics). 360º Engineering offers civil, structural, electrical, mechanical and plumbing. 360º Management provides development, project, construction and place management.

In addition to projects in Singapore, ONG&ONG has also completed large-scale developments regionally. This has prompted the setting up of offices in China, Vietnam, India, Malaysia, USA and most recently in Indonesia, Mongolia and Abu Dhabi. In-depth knowledge of the local context, culture and regulations allow us to better understand our clients’ needs. We are an ISO14001 certified practice and consistently strive to meet and exceed our clients’ expectations.

Corporate History
Founding partners, the late Mr. Ong Teng Cheong and Mrs. Ong Siew May, established Ong & Ong Architects in 1972. Since its humble beginnings, the firms’ staff strength has grown to almost 900 over the past four decades. Going from strength to strength under robust and exceptional leadership, the organisation was incorporated in 1992.

2003 and 2004 marked the years when we ventured into interior and landscape design respectively. In 2005, our first overseas office was set up in Vietnam, closely followed by our China, Malaysia and India offices a year later.

2007 saw our integration with ECP Architects International while ADT and AT‐ii joined us in 2008. In that same year, our project management arm, Project Innovations was formed as well. Finally, as of 2011, SCE Consultants (Pte.) LtdTSP Architects & Planners Pte LtdKD ArchitectsDLQ Design and SCA Design have also joined us to establish the current ONG&ONG Group.
