Building a suite,
made simple.
Kasa Suites is the garden & laneway suite brand of Atena Construction — a family-run Toronto design-build team with 25 years of building experience across the GTA.
We started Kasa because building a backyard suite was harder than it needed to be: an architect here, a contractor there, permits somewhere else — quotes that never matched, and nobody owning the result. Kasa puts the whole path under one roof: one team, a curated line of nine proven models, fixed transparent pricing, and permits handled end-to-end. From the first site visit to the day we hand you the keys — faster, clearer and more complete, without the back-and-forth.
Why homeowners choose us
Every Kasa suite is built to a high-performance standard — engineered envelope, quality finishes from our published standards catalogue, and a fixed price agreed before construction starts. The suites in our gallery are real builds in real Toronto backyards — designed, permitted and built by the same team, start to finish.
Where we work
Toronto and the GTA — including Scarborough, North York, Etobicoke, East York and the downtown east and west — plus Mississauga, Hamilton and York Region.
