If you are sure it is non supporting then all you have to watch for are pipes and cables that may run through it.Removal is dead easy. Remove the plasterboard and then either cut it up into manageable pieces to carry off or just take a large hammer and enjoy yourself.!!!!!
I hope you're really sure that it isn't supporting anything.
Sometimes studwork walls are supporting floor joists, trimmers staircases or roof members. Most of the 30s semis round where I live have original studwork holding up the Queens holding up the Purlins. Removing just a door frame (I mean the frame, not the lining) without moving the load could bring half of the roof down.
If the wall is lath and plaster, expect plaster dust everywhere.
Yup - it was just a stud. Due to some confusion with building control a small smoke lobby was built which cut out a large corner from the room. We were in the process of buying the place and were keen to get permission to remove the wall which only went up about a year ago. The guy at the council couldn't think why he'd asked for it to go up in the first place and gave us permission to take it down. Which we did, quite easily. Now we've taken it down and tidied up the where it joined the remaining wall and you'd never know it was ever there
