What do we do

3 Fields of expertise


1- Design Management

2-Site Management

3-Project Management


T20 Studio consider that being in control of the design and construction phases of a project is the key to successful completion.

Design Management:


Our projects must adapt to new ways of living and working, incorporating technical innovations designed to make their use easier and better. Users’ well-being, capacity for transformation/ reversibility of spaces, energy management, can no longer be ignored when undertaking a project. It is our capacity for anticipating requirements, and providing expert advice and pertinent recommendations, that leaves us convinced of having the right approach.

Site Management:


The Architect is the true conductor of the operation. It is our central position and the knowledge collected that allows us to be often in the best position to determine the most cautious adaptations to adopt during the worksite.

The site is the result of collective work; it is crucial to clarify the final details of the project. The presence of the architect during this key phase will ensure respect for the essence of the project.

Project Management:

Planning, initiation, execution, monitoring and closing the project are our expertise. We ensure projects are designed and built on time and to budget while protecting the integrity of the design and respecting its quality.
