Corporate Profile
With a track record of almost 40 years 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.
Partnering our clients in their race to the top, ONG&ONG now offers a complete 360o solution - i.e. a parceled 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). Engineering 360o offers civil, structural, electrical, mechanical and plumbing. Management 360o 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 and Malaysia. 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. To grow our international reputation, ONG&ONG has now set up an office in New York, USA.
Corporate Philanthropy
The spirit of philanthropy is deeply embedded in the culture of ONG&ONG. Education is a key component of ONG&ONG"s philanthropic effort, centering on the architectural community. The ONG&ONG Travelling Fellowship was first established in 1997 with the objective of allowing gifted undergraduates the opportunity to pursue the knowledge and experience of the built environment through independent travel. In 2000, the Ong Siew May Professorship was set up to pave the way for world eminent practitioners to lecture at the National University of Singapore"s Department of Architecture. This exchange and transfer of knowledge is elemental in grooming the architects of tomorrow. ONG&ONG also sponsors the BCA-Industry Built Environment Scholarship.
In addition to our commitment in supporting design excellence, ONG&ONG established a Preceptorship Programme with Rice University since 2000 and Internship Prizes with UC Berkeley, Harvard University and Pontificia Universidad Javeriana in Bogota, Columbia.
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 600 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.) Ltd, TSP Architects & Planners Pte Ltd, KD Architects, DLQ Design and SCA Design have also joined us to establish the current ONG&ONG Group."
