Another approach is to consider building a wilderness shelter instead of hackspace. There are many shelters in BC - I’ve been to most of the ones between Vancouver and Joffre Lakes and quite a number on the sunshine coast. A significant number of them are either on crown land or in provincial parks.
Examples:
Keith’s Hut
Elfin Hut
Mt. Steele Cabin
Lake Lovely Water Cabin
Brew Hut
Burton Hut
Each shelter is upkept by different organizations: BC parks board, Alpine Club of Canada, Varsity Outdoors Club etc. A few are also maintained by more private organizations (I think Keith’s Hut falls under this category).
I don’t know the exact requirements necessary to build wilderness cabins on government land, but I assume there is a permit process. If you can demonstrate that building a cabin in a certain location will be a benefit to the public, I bet you would have a shot. You might need to call up the government (provincial or federal, depending on who owns the land) in order to figure out the process.
