Our Vision
Three Squared is a Detroit-based, award-winning infill architectural design firm specializing in efficient residential and commercial prefabricated design.
We believe better housing isn’t just possible—it’s necessary. At Three Squared Inc., we’re leading the shift toward smarter, faster, and more sustainable buildings.
With every modular steel project we deliver, we challenge outdated systems, cut timelines, and design for what cities and communities truly need—today and tomorrow.
Balancing Upfront + Long-Term Value
Our architecture is built for speed, precision, and real-world permitting. Whether you're a developer, city agency, or modular fabricator, we design with your endgame in mind: reduced delays, fewer surprises, and high-performance buildings that meet code the first time.
Endorsed by Experience
With ICC-backed systems and decades of proof, our builds are trusted from the ground up.
Designed to Last
Steel-framed systems deliver durability that surpasses wood by decades.
Lifetime Cost by Design
We weigh upfront costs against operating and maintenance savings to deliver buildings that outperform in the long run.
Engineered for Excellence
Every module is fabricated in a controlled environment for flawless execution.
A Clear Path From Idea to Occupancy
From feasibility through delivery, our approach integrates prefabrication, coordination, and performance at every step.
What is Prefabrication?
"Prefabrication," often shortened to "prefab," is the process of manufacturing building components or complete assemblies in a factory or other off-site location, then transporting them to the construction site for final assembly.
