In multi-family residential architecture, balconies are often seen as simple additions—extensions of the floor plate that check a box for outdoor space. But when you step back and look at them as part of the building envelope, livable square footage, and long-term operational performance, they become far more consequential.

With evolving climate demands, stricter energy codes, and increasingly discerning occupants, how you approach balcony design can have real implications—not just on comfort, but on cost, durability, and return on investment.

So how do traditional open balconies compare to glazed systems like Lumon? Let’s take a closer look.

The Role of the Balcony Is Evolving

Balconies are expected in mid- and high-density developments. Buyers and renters often see them as non-negotiable. Yet despite their desirability, they’re typically the first to be value-engineered out of performance conversations.

But in today’s regulatory and market environment, outdoor spaces need to do more. It should contribute to energy efficiency, durability, and occupant satisfaction—not just provide a view.

Traditional Balconies: Simpler, But Not Necessarily Smarter

At first glance, traditional open-air balconies seem like the obvious choice: they’re straightforward to design, familiar to contractors, and meet basic occupant expectations. But in the broader context of high-performance building design, they often introduce more challenges than they solve—particularly when it comes to durability, energy efficiency, and occupant comfort.

Glazed Balconies: Flexible, Functional, and Resilient

Glazed balcony systems like Lumon are frameless, retractable glazing systems that convert traditional balconies into flexible outdoor rooms. Glazing protects the space without fully enclosing it as an interior area—preserving the outdoor experience while extending its usability.

Key Takeaways for Architects and Developers

Balconies are often overlooked in early design decisions—but that’s precisely where their potential lies. Here’s what to keep in mind when evaluating whether traditional or glazed balconies are the right fit for your next multi-family project.

• Don’t design the balcony last: Treat it as part of the envelope and living space strategy—not just an exterior appendage.
• Plan early: Successful integration of glazed systems depends on early coordination between architects, structural engineers, and façade consultants.
• Think long-term: Traditional balconies may reduce costs upfront, but glazed balconies reduce operating costs and improve value over time.
