Raised decking supported by scaffolding

Good afternoon Jane! Ultimately if the scaffolding is erected correctly and the decking/scaffold boards are tied in (secured to the scaffolding) then it should be fine. Obviously decking is usually laid on a sub-frame as using a base structure like scaffolding would simply be more expensive. Needless to say if the timber is old and rotted then you will have to replace it. I hope this helps.

The scaffolding while supporting the decking is not very attractive and not suitable. A wooden support system with posts concreted into the ground would be what I would recommend. Paint the bottom of the posts with bitumen to give added protection.

Scaffolding is only anywhere a temporary measure.Not knowing the full picture I would secure decking from the ground up with substantial structure posts that are post mixed to hole in ground.Then batten between upright posts to conceal

Need to go on a sup frame
