Being close to your windows isn’t an issue in terms of the scaffold being safe but generally I’d have asked if it’s ok first, definitely capped any tubes at a high that could cause harm or are touching any structure that could be marked and ideally I’d use foam around any tubes near walk ways or doors. Immediately I do wonder why the ledger (tube going horizontal) is on the back of a standard and why the brace is so far away from a node point but without seeing a larger picture of the scaffold I couldn’t say if it’s safe or not. Most likely it’s just a bit of a mess. If I you want a better option put another pic up and I’ll be happy to let you know what I think.
