Concrete Fins
Concrete fins: vertical or angled cast-concrete blades used as sunshading, screening and facade rhythm on buildings.
Concrete fins are projecting vertical or angled blades of cast or precast concrete attached to a building facade. They shade glazing from low-angle sun, screen views and give a repeated rhythm to otherwise flat elevations. Designers use them to balance daylight, privacy and visual character without relying on mechanical shading.
Community work under this topic looks at how fins are spaced, angled and deepened across different sites, from dense urban commercial blocks to residential and campus-scale projects. Contributions also examine how fins interact with neighboring buildings, streetscapes and landscape settings.
