The Fast + Epp „Concept Lab“ is a collection of web apps that give architects the tools they need to visualize their schemes at the early stages of design. Use the calculator to determine member depths of various structural components, and the material gallery to get a sampling of how those materials would look exposed.

Concept is also available as a free iPhone app. Acting as a structural engineer at your fingertips, architects can explore the aesthetics of wood, concrete, and steel, and to determine each material’s feasibility and depth. The application combines the creativity of architecture with the practicality of engineering.
