prioritize those required hacking/drilling first

carpentry normally the last then move in your furniture

i assume you staying condo?

i install the grill in later stage because they are not that messy to install and also can avoid some dents/scratches/dust during renovation

In project planning some stuff can be done in parallel. Main door grille can go independently. The windows or yard grille after aircon ODU fixed is better.

Wiring for concealed points need hacking. Suggest to add more especially TV, bedroom, PC room and kitchen. Might even take the opportunity to inspect all existing sockets and switches because sometimes they don’t even screw in the cable properly. Loose connection cause 🔥
