Our clients benefit from our expert knowledge of inclusive access standards and our project methodology.

Convinced that the concept of Universal Design is a key component to good architecture and design while facilitating social inclusion, we seek to achieve universal accessibility, where possible, by applying best practices standards through a user-centered approach.

This is in line with current national and international legislations that seek to move towards a more inclusive society, and place a wide range of duties on organisations to ensure that all people get the chance to participate fully in society.

Trained architects and new-technology experts, our access consultants offer a tailored access consultancy service to our clients, providing expert knowledge to design and client teams, at all stages of the project.

OKEENEA brings together the access expertise of EO Guidage, Access for All and Univaccess.

Our company OKEENEA relies on two founding principles : decrypting specific needs and developing inclusive digital solutions.

By reunifying the 3 entities under a single brand, the group of companies proposes to its clients, owners and facilities managers, highways engineers and public transportation systems managers, a global approach towards access. This implies services such as : access consultancy, consultation with the stakeholders of the project, the development of inclusive access solutions, its manufacture with or without implementation, in simple and complex projects.
