About ATO Architects

Getting to know who we are

The Beginning.

A.T.ONAJIDE ASSOCIATES came into being in 1987 when it won a competition for the design of the largest recreational squash court complex in West Africa for the Ikoyi Club 1938.

In 1996, it became incorporated as A.T.Onajide Architects Limited and subsequently ATO Architects Limited.

Our vision at ATO Architects is global.  We have always been at the cutting edge of project and service delivery, especially using every tool that information and technological advancements avail us.  We continue to strive to provide the very best architectural and management services promptly, accurately and professionally, and deliver these services better every time.


With a solid operational base in Nigeria, ATO Architects is also registered to practice in the United Kingdom and in South Africa.  We have been invited to submit proposals for a number of key developments in Cameroun, Ghana and Liberia and besides Nigeria, have completed projects in South Africa and in the Republic of Benin.

We continue to strive to provide the very best architectural and management services promptly, accurately and professionally.

The range of project types that we have designed and managed to completion is very broad and includes work in Oil and Gas, Aviation, Education, Ecclesiastical, Banking and Finance, Corporate development, Hospitality, Healthcare, Recreation, Residential and Housing, Commercial and Retail.


In our bid to provide the very best architectural services to our clients, ATO Architects Limited has formed bilateral professional partnerships across borders with architectural firms in the United States, Egypt and France to compete for work on an international level. In 2010, partnering with a firm of architects from Louisiana, USA, we created the winning entry on a major design competition for an international oil and gas conglomerate.

We are confident of our ability to offer our services to individuals and corporations in other countries either in our own capacity or as part of a multidisciplinary group and are also proud of our proven ability to represent international firms locally on selected projects.


At the core of everything we do is the visualization of possibilities along with our Clients and helping them turn possibility into reality.  We recognize at all times our corporate responsibility to always help to protect the environment and do not take this lightly.
