What is a stacker balcony system?
A stacked or 'stacker' balcony is a self-supporting structure where each level sits atop the one below. The weight is carried vertically through steel support legs directly to a ground-level foundation, rather than hanging off the side of the building.
Can these be installed on any building type?
Stacked systems are incredibly versatile. They are the preferred choice for older masonry buildings, timber-frame structures, or any project where the existing wall strength is a concern or unknown.
When is a stacked balcony better than a bolt-on?
While bolt-on balconies are excellent for new builds with high-strength concrete frames, a stacked system is often the ideal choice for:
Existing Buildings/Retrofits: When you want to add balconies without opening up floors or walls to add internal reinforcement.
Older Masonry: For buildings where the wall strength may not be sufficient to support the "pull" of a cantilevered bolt-on.
Multi-Story Consistency: When you want a uniform, "floor-to-ceiling" vertical line that runs the entire height of the building facade.
Does the balcony attach to the building at all?
Yes, but only for lateral stability. The building keeps the balcony from swaying or moving sideways, while the steel legs handle 100% of the vertical weight. This prevents the structural strain and "facade pull" associated with traditional cantilevered designs

Which system is faster to install - stacker or cantilever?
On an existing building, a stacked system is often faster because it requires less structural preparation. Because we aren't "tying in" to the building’s internal steel or timber as heavily as a bolt-on requires, the on-site disruption to residents is usually minimal.
