Toronto Skyline

Reaching New Heights in Sustainable Design

We're not just drawing buildings anymore - we're crafting vertical ecosystems that actually give back to the city.

About Halcyon Spire

Building upward, thinking forward

Over the past decade, we've learned that the best high-rises aren't just tall - they're smart. Every tower we design is a chance to rethink how people live, work, and connect in dense urban spaces.

Started in Toronto's core, we've watched this city grow vertically at breakneck speed. That's pushed us to stay ahead of the curve - mixing residential, commercial, and public spaces in ways that actually make sense for how folks want to live today.

What We Do

Services that scale with your vision

From sketches on napkins to ribbon-cutting ceremonies, we're with you through every stage.

Residential Tower Design

Creating homes in the sky isn't easy. We focus on getting light right, maximizing views, and designing amenity spaces that people actually use - not just fancy renderings.

Mixed-Use Development

Live, work, shop, play - all in one place. We've spent years figuring out how to stack different programs vertically without anyone getting in each other's way.

Sustainable Architecture Consulting

Green washing? Not here. We'll help you hit LEED targets, reduce energy loads, and design passive systems that actually work in Canadian winters.

Urban Planning & Master Planning

Zooming out to see the bigger picture. We'll help you understand site potential, navigate zoning, and create development frameworks that cities actually approve.

Building Performance Analysis

Numbers don't lie. We run detailed simulations on energy use, daylighting, and thermal comfort before anything gets built - saves headaches later.

Heritage Building Restoration

Old doesn't mean obsolete. We've gotten pretty good at breathing new life into heritage structures while respecting what made them special in the first place.

Sustainable Design
Our Approach

Sustainability isn't optional anymore

Let's be real - every building we design today needs to perform better than the last. Climate targets aren't getting any easier, and energy costs sure aren't going down.

Energy modeling from day one

We don't wait until schematic design to start thinking about performance - it's baked into our process from the first sketches.

Materials that make sense

Low embodied carbon, local sourcing when possible, and durability that actually lasts. We're done with stuff that looks good for five years then falls apart.

Future-proofing everything

Buildings we design today need to adapt to how people will work and live in 30 years. Flexible floor plates and redundant systems go a long way.
