Maybe, maybe not. Don't risk it.
You will be putting a cable in for power. Put a duct or exterior grade network cable in at the same time (fibre if you are feeling fancy). The materials aren't expensive and there is little extra work.
Any idea what this would cost and anyone recognise design? It's 3.0m x 2.5m.
Looks like these guys are quoting around £14k inc foundations and installation for same size: https://www.gardenstudio.co.uk/products-and-prices/garden-workshop/
