We're not your typical studio

Look, there's plenty of firms out there churning out buildings. We get it. But here's the thing - we've spent the last decade figuring out how to create spaces that don't just look good in photos but actually work with the environment, not against it.

Based in Toronto, we've tackled everything from converting old warehouses into modern homes to designing commercial spaces that actually reduce energy bills. Sustainable design isn't just a checkbox for us - it's kinda become our obsession.

What we actually do

Six core services that we've refined over the years. Each one's a bit different, but they all share the same DNA.

Residential Architecture

Your home shouldn't just shelter you - it should actually enhance how you live. We design spaces that fit your lifestyle, not the other way around.

Commercial Building Design

Offices and retail spaces that people actually want to be in. Plus they're efficient enough to make your accountant smile.

Interior Space Planning

Sometimes the exterior's fine but the inside? That's where the magic happens. We reconfigure interiors to unlock their full potential.

Sustainable Design Consulting

Already got a design? We'll show you how to make it greener without starting from scratch. Real solutions, not greenwashing.

Heritage Building Restoration

Old buildings have character you can't replicate. We restore them while adding modern functionality - best of both worlds.

Urban Planning & Development

Thinking bigger than single buildings. We help shape neighborhoods and developments that actually improve communities.

The sustainable thing isn't optional anymore

We started focusing on sustainable design back when it wasn't the trendy thing to do. Now? It's pretty much mandatory if you're building anything worth its salt.

Every project we take on gets the full treatment - passive solar design, material selection that actually matters, energy systems that pay for themselves. We've gotten good at balancing aesthetics with real-world performance.

It's not about being perfect. It's about making better choices at every step and creating buildings that'll still be relevant in 30 years.
