Abstract: A system of tracks, brackets and containers, typically empty beverage cans, assembled and used for temporary storage, temporary emergency shelters, toys, or other uses involving inexpensive and light weight building materials. The system is implemented by releasably attaching the containers to the tracks, then releasably attaching the tracks to each other either horizontally, vertically, or both to form structural elements such as beams, columns, or panels. The rigid tracks are made from a material which allows for apertures in the tracks to be sized to resiliently snap onto portions of the containers. The track may be formed in a variety of different shapes, such as straight, angled, curved, T-shaped or cross-shaped. Additionally, the brackets may be formed in a variety of different shapes to attach the track assemblies to each other in various orientations.
