Advice needed for building a compact terrace shed with my brother
My bro and I are planning to build a small terrace shed on our apartment rooftop to improve storage and create a small usable space. Without making the area feel cramped or difficult to move around in. We are both beginners in construction. So we are trying to keep the design as simple as possible. Though still making sure it can handle basic outdoor conditions like sun, light rain and occasional wind. The idea is a lightweight frame using either treated wood panels or thin metal sheets. Depending on what offers the best balance between durability, cost and ease of assembly. We have been comparing different materials and frame styles online, including some eBay, Amazon and Alibaba listings. But it is clear that similar-looking options can vary a lot in thickness, coating and load capacity. Which makes choosing harder. Our main concern is building a stable base so the structure does not shift or weaken over time. We are also trying to avoid complex methods since we only have basic tools and limited experience. We are unsure whether a raised metal frame or simple concrete footing makes more sense for a rooftop setup. What would you prioritize first when planning a project like this?
