EXTERNAL ENVELOPE
Beyond the facade, balconies have become integral elements in aesthetically appealing, mixed-use developments. However, integrating these features seamlessly into a building’s structure, especially in high-rise or unusually shaped buildings, presents significant engineering challenges. Engineered balcony connector solutions
address these challenges head-on and their correct specification is crucial for ensuring structural integrity, thermal efficiency, and fire safety. Balcony connectors are that critical link between the balcony and the building structure, transferring loads and accommodating movement.With continuous innovation, thermal connections allow architects to design balconies that appear to be natural extensions of the building’s form, rather than afterthoughts.
A case study with curve appeal Folkestone’s Shoreline development showcases how innovative engineering solutions can bring complex architectural visions to life. The project’s distinctive curved design, featuring convex and concave elements and a glazed white brick facade, presented unique challenges for masonry support and balcony integration.
Custom-designed support systems were crucial in realising the building’s curved structure. Engineers developed bespoke brackets and channels to support the masonry and precast brick soffits, carefully coordinating with window locations at every level. Special fabrications were created for acute corners, for seamless integration with the unique geometry.
Non-standard brackets were designed to connect steel balconies to the curved concrete frame, navigating potential clashes with reinforcement in the congested slab edge. This demanded close collaboration between design and production teams. Another important consideration was material selection for structural components. Due to the coastal location, grade 316 stainless steel was chosen to withstand the high salt content of the sea spray in this harsh coastal environment. The project demonstrates how early engagement and close collaboration between engineers, contractors, and manufacturers can overcome complex design challenges.
