Hey Harsha, yeah the bevelled mirrors look gorgeous, and blow the budget of a room on that. haha! You could also opt for back painted glass, or tinted mirrors, that way you'll add some flair of a reflective surface, but you won't need to spend too much on making the mirrors themsleves a quirky characteristic!

Veneer with White PU is a great Option. Alternatively you can go with Duco which is slightly cheaper than PU. Laminates always have a sharp edge unless done with the right expertise. Fabrics, if going with white, should be scotch-guarded. Mostly, white PU will work on table tops too, but if you want to use a sturdy option, go for white lacquered glass or White marble.

Sonam, This finish can be achieved on multiple surfaces. Ask about distressed finish to your designer they will be able to help you. Thanks, Nitin CORNERSTONE DESIGNS Bangalore

There is nothing special about Kerala climatic conditions that require anything special (yes, I have several years experience with kitchen cabinets there). You can use BS 710 or 303 plywood with laminate on them with excellent results. Several interior firms also use HDF/MDF with laminate without much complaints from their clients.
