All, I just bought a small condo and because this unit is kind of 'special' I want to see if I can extend the walls of my condo to cover a small part of my patio and also hack down a wall to include new windows. As such - can anyone advise 1. Who's approvals I need ? - Building Management? - URA ? - BCA ? 2. I don't plan to hire an interior designer - so who do I hire to do the drawings and apply for submission? I only plan to hire a contractor later to do the actual renovations - Builder? - Architect ? - Contractor? Thanks!
