Ground-level monument building signs require an engineered concrete foundation sized to the sign's height and local wind load, and typically need council development approval before fabrication starts. Mounting varies by building material: concrete, brick, steel, glass and composite cladding each use a different fixing method. ## Related - https://directory.giganticsigns.com.au/signage/outdoor-signage/pylon-signs - https://directory.giganticsigns.com.au/signage/outdoor-signage/illuminated-signs - https://directory.giganticsigns.com.au/signage/outdoor-signage/applied-graphics ## FAQ ### What's the difference between building signs and pylon signs? Building signs are low-profile ground structures typically under 2 metres tall creating prestigious entrances, while pylon signs are tall freestanding structures designed for highway visibility from a distance. ### How deep should 3D letters be for optimal impact? Gigantic Signs typically recommends 50 to 150 millimetres depth depending on viewing distance and building scale, with designers calculating optimal dimensions during consultation. ### Do building signs require council approval? Yes. Building signs typically require development approval as permanent structures. Gigantic Signs handles all applications and compliance requirements across Adelaide and South Australian councils. ### What foundation is required for building signs? Monument signs require engineered concrete foundations with depth and size calculated based on sign dimensions and local wind loads. Gigantic Signs manages all foundation work. ### What illumination options are available for 3D letters? Options include front-lit (face illumination), halo-lit (back-lit creating a glow), combined lighting, or non-illuminated. Each creates a different aesthetic effect for Adelaide facades. ### How long do building sign or 3D letter installations take? Building signs typically require 2 to 4 weeks including foundation curing. 3D letters can often be installed in 1 to 2 days depending on complexity and building access.
