There are many hovercraft plans available on the Internet, but the hovercraft design you choose should be selected after you consider the characteristics best suited to how you intend to use the hovercraft.
There are many homemade hovercraft on YouTube - Universal Hovercraft provide plans and hovercraft kits, but before you buy, consider the following points.
Hovercraft are weight sensitive - race hovercraft are incredibly lightweight, and not very durable, and not particularly good over water. What weight do you wish to carry? Are you hoping to take passengers? This is particularly important if you plan to start a hovercraft from an on-water start, since all hovercraft create a pressure wave known as Hump, and some hovercraft with smaller lawn mower engines have great difficulty getting over hump. Check the on-water payload, which is generally 50% less than the payload quoted for the hovercraft when it starts on land. Some suppliers are a tad economical with the truth about on-water capability, and are inclined to show images of 4 people flying over puddles in fields - remember, when starting the journey on land, the hovercraft picks up 50% more weight - but if for any reason you have to stop on the water, perhaps to top up the fuel, if you are over the on-water weight payload, you may have to swim home and abandon your hovercraft.
