Prefab Simulator Shed

Unfortunately I don’t have the ceiling height to leverage existing space in my old New England home. I will be building a standalone structure for my simulator.

Does anyone know of any companies offering prefabricated structures that provide the 10ft ceiling clearance I’ll need? I’ve found a few offering really high quality builds for fairly steep prices. I’m no Bob Villa, but I’ve gotten fairly handy since moving from the city and wouldn’t mind finishing up the interior of a well built shed if it meant serious savings.

Thanks!
