A Design-Focused Architecture Practice with Emphasis on Modularity and Sustainable Design

Our Origins

STE-AD is an architectural practice founded by Sean T Ellis, AIA in 2021 in Hong Kong.

Having gained experience working for several prominent, international Architecture firms in New York City and Hong Kong, STE-AD was founded to prioritize a few key elements of Architecture:

  • Sustainability
    To focus effort and research on reducing carbon footprint within Architecture and the built environment
  • Modularity
    To make components of Architecture repeatable, yet customizable, to reduce cost and potentially benefit Sustainability
  • Design
    To push design further and to create beautiful and provocative places and objects will always be at the forefront of what we do

Our Experience

Nearly 20 Years of experience working in large international firms in New York and Hong Kong will be put to use in the formation of STE-AD.

That experience includes working on a wide range of high profile commercial, residential, and cultural projects throughout Asia, Europe and the USA.

Our Focus

At STE-AD we emphasize on engaging design with the intent of creating simple, yet provocative experiences.

We do not wish to be interesting, we wish to be good. We provide services in Architecture as well as several fields of design.
