Steel Frame Pergola for outdoor kitchen

Looking at building and outdoor kitchen/seating area in my backyard. I don't really want to have pour a full slab so thinking about using something like this as a base rather than a traditional wooden pergola, i can just lay modwood or something directly onto the frame. https://bespokemodularliving.com.au/products/3m-x-6m-skillon-roof-frame Has anyone used a kit like this? Anything i should be concerned about? I will probably need to pour some footings to bolt it into but that should be easier than having to lay a whole new base for it. (the back part will be over dirt the front over existing pavers)
