Malaysian eaglet,
Can you please provide a reference which confirms that hour-building must be "structured"? It may be the case for an integrated course (I'm not sure, I don't know very much about integrated courses) but it's certainly not the case for a modular course.
Obviously, flying around the circuit for 100 hours is no use to anyone. And neither is flying return trips to an airport 50 miles away which you know well over and over again. There is certainly a lot to be said for applying some structure to your hour-building. The long cross-country that's required for CPL issue must be completed. If you don't have a night qualification by the time you complete your hour-building you'll have to do the night qualification as part of the CPL. The merits of doing an IMC course during this time are being discussed on another thread. But there is no formal requirement to have any particular structure to your hour-building.
