first thing first.. renovation to add new power point, plug, wire route.. with condition current distribution wiring capable to support. whole house will be hack here and there..

u need to think of aircond fixture.. fans power point .. some old room only have 1 point for light.. same goes to kitchen area.. wifi and router ..

later on to add cctv power point, smart home..
mean better u settle this first..

once this wiring plan well, then u can think about light feature, smart home, fans, aircond.. additional plaster ceiling..
