Wooden garden room, 2019 vintage. All fine until the recent weather seems to have slightly disorted the building or the base it sits on, causing the doors to stick. I should be able to adjust that out by the hinges (see second pic), but at least one of the Allen-headed screws has nearly rounded off. The suppliers say they import these rooms as kits and don't supply hinges separately, but will check to see if their fitters have any left over. In the meantime I have scoured the web for direct replacements or something suitable instead, to no avail. I want whatever goes on to be adjustable as this may not be the last time there is movement. The closest I can find is https://tinyurl.com/ywedw55f but those would need a bit of woodworking to bring frame level with door. Grateful for any advice.
