Make sure it's legal to build it where you plan to, there can be hidden restrictions and limitations on the height of a structure near say a fence in any contracts that passed on when the house was purchased.
Those kits, especially for that price, usually don't have great weatherproofing so won't look as good in a year or two, still the structure itself may outlive your desire to use it for VR. I'd also grab some carpet for inside too.
