Squarehouse Studios was formed as collaborative partnership between Mary Flo Ouellette, Allied ASID and Steven Santosuosso to create timeless and curated interiors that tell the story of our clients. We provide complete design services for residential and commercial spaces.

Community work is also at the heart of our mission as we strive to provide sustainable and responsible design through our work with local artisans and trusted suppliers.

We'd love to hear your story!

It’s funny to think that I arrived with nothing, and we created this beautiful apartment that feels so much like me.

Mary Flo and Steve are a pleasure to work with, planning and designing every detail of our project. They conceived a plan that completely overhauled the space from floor to ceiling and created a flow to it all. It’s become a place where we all want to live.
