I applied initially to MPK for renovation via submission of new BP. Ended up it was put on hold due to changing from 1 storey to double storey, so a KM/DO is required that took me additional 5 months.

Renovation submission or BP is quite fast, if every supporting letter is in place, it would be approved within 1 week.

Cheers
