is an Architectural Practice with a Studio in Montclair, New Jersey. Our work encompasses Architecture, Landscape Architecture, Professional Planning, Site Analysis, Master Planning and Sustainable Design. Our diverse Studio is made up of Architects and creative thinkers working with an understanding of our clients’ needs and their vision. Our staff is currently engaged in projects throughout New
Jersey and New York. Our in-depth knowledge of local markets is combined with a design history and expertise developed over more than 25 years in mixed use commercial developments, religious, residential, retail, healthcare and childcare, athletic, civic & government as well as a commitment to building green. A passion for designing and delivering buildings and site plans of the highest quality has been at the heart of Sionas Architecture since our beginning in 1985. This passion remains at the core of our practice today and award winning projects such as the recently completed Hillside Square (formerly the First Church of Christ Scientist) and Academy Square (formerly the Katherine Gibbs School) in Montclair are shining examples.
