Three types of balconies are typically used for multi-dwelling properties: stacked, hung, and cantilever. Stacked balconies are the most common due to their simplicity; they’re a separate structure supported by vertical pillars or posts. Hung balconies are supported by stainless steel cables that are attached to the building and a large plate. Lastly, cantilever balconies sick out of buildings without any visible supports – they’re built into the original design.
