The kit includes labeled parts, stainless hardware, required tools, and step-by-step instructions, and Grandio provides official assembly videos.What foundation do I need?The included steel base kit creates a rigid perimeter frame that works on concrete, wood decks, or bare ground. Just pick the matching anchor option so the hardware fits your surface. Earth installations use L-bolt anchors, often set in concrete for extra hold.How does the Ascent differ from the Element?The Ascent is the step-up hobby line: a taller 7 ft 9 in peak, wider 8 ft footprint, wider doors, plus the steel base kit and snow load kit included as standard. The Element uses thicker 10mm panels in a smaller 6 ft wide format.Can it be used year-round?Yes. The twin-wall panels retain heat in cooler months, and the roof vents manage summer temps. Many owners add a small heater for frost protection and shade cloth in peak summer.
