Tomb Raider Anniversary - Croft Manor [Broken]

NOTE: This level took me over an hour to solve so I tried my best trimming it down and speeding certain parts up without cutting any important parts out, so I hope this is still watchable... After a long grueling adventure and saving the world from Natla and her Denizens, Lara Croft returns to her family home in the UK. But when she arrives she finds a note from her faithful butler Winston to tell her that a shipment of antiquities have arrived while she was gone and the water mains is switched off and a faulty security system?? Looks like Lara has one more job to do before she can get her well deserved rest...
