hey, i am looking to build a decent size shed/workshop at the house ive just moved to, but am running into a few issues. The site where it needs to go has easement for gas running underneath, it's already paved so an ideal base but upon reading deeds and online info i run the risk of them needing access to the pipes one day... So my potential solution is to build the shed strong enough to be moved by a forklift if it ever needs... Will it be strong enough (gonna build it solid myself not a flimsy online one)? the dimensions will be 3.5m x 2.2m so pretty big, could a forklift do this? im assuming the base being solid is the key thing for it to be lifted? any advice most welcome.

I have a Four Seasons Sunroom that is 13 years old. There have been no problems or leaks. It is conservatory style with aluminum frame and vinyl. I recently had someone from the company come out to look at a door that I wanted replaced. While he was here he suggested I have the entire structure re- caulked, including the roof glass which was never caulked, even when it was installed. It just has the rubber weather stripping. He insists its the right thing to do to keep the windows from losing their seal due to water and ice buildup in the winter. These sunrooms are notorious for leaking. I am leary about having him up there fixing something that's not broken, and am afraid that he has a better chance of breaking a windows seal than the winters ice ever would. I can't find any other professional to advise me if I should do this. I would love any wisdom or experience anyone is willing to share.
