A paver supporting apparatus is provided and includes a pedestal and a modular grid. The pedestal includes a top plate with a plate extender and a plurality of male lock pins positioned around a circumference of the top plate. The modular grid is positioned and secured on the top plate such that the top plate supports the modular grid in an elevated position and connects with one of the plurality of male lock pins. The modular grid includes a lattice extending generally between perimeter edges of the modular grid and defining a plurality of lattice.

An expandable structure has an expansion section with side wall panels that can stack into and be deployed from a wall enclosure central housing. A track can be deployed on the wall enclosure for facilitating the movement of wall panels into and out of the central housing. This innovative configuration not only enables efficient and accurate storage of each wall panel within the central enclosure but also concurrently serves as the foundational support structure for the cabin. After the wall panels are deployed and the structure is fully expanded, the wall panels can be tightened together to provide sound and weather protection.
