There are many hosting businesses. The newest would be the expansion to heavier hobby facilities and tools with access to skilled instructors. (not necessarily certified but could be craftsmen with years of experience)
Now there are many hobbyist with no place to practice their hobby in todays environment where most persons live in multi tenanted dwellings or even rather small somewhat exclusive lateral dwellings.
So as such arises the need for space to just be able to work on that project, be able to leave in some what a ready to continue state till the next opportunity arises. Another good match is to provide tools on a lease or rent basis. Consumables such as fuses, blades etc can be bought on a need basis but the base tool could be rented to the hobbyist.
Along with that is to conduct trainings, guided project kits, mentoring and much much more. Even the sale of materials be it on order basis or ready of the shelf.
This kind of business would fall into the Share Facilities Business Segment. Much like the Virtual Office Business which is normally hosted along with a Shared Serviced Office Business.
Note that the Business Ideas segment is to give ideas and is just to encourage people whom are looking to start a business. Be it for additional income, just looking for change or opportunity. Information provided is just on a level of concepts generally, some level of detail may be provided as example only. It is best should an individual or group of individuals wishing to use the idea to do through research prior to implementing the ideas. Most of the ideas require adaptation and also further detailing to be even ready for deployment. Take it as a seed. The writers and the host platform is not responsible for any results arising from the use of any ideas that have been made available free of charge in seed form.
