You sound like a ID already, bet you did some serious research.
I know about those materials while working out with my contractor renovation on hdb where my parents are staying.
I call him contractor as there is no drafting, just discuss over photos and doing the measurement on the spot. I am also not too particular about outlook, the workman ship is good. Now of course is different cos my wife had higher expectation on outlook whereas i go for practical function.
The quote you had is around my estimate budget as i want to get a nice dinning table & sofa. As for appliances, fridge & tv i am using is still < 1 year so those are secondary, only need to get washing machine/dryer.
Considering only to have L-box on the sides with squarish down light, and to install a big ceiling fan, dont know if it will looks 'funny'.
Three of my colleagues took keys to their apt recently, all condos and all there had complained a lot about their IDs, maybe they had too much expectations. Or IDs are good at design but not at managing carpenters/electrical/painters. Hope your experience is better.
