hello.. any suggestions would be of great help!! I am very confused right now

Looks like saltpetre which is leaching through the brick. You may hae waterproofed the outside but what about water leaching from the roof. Water will find a way.... Here is an interesting link... http://www.arcane-industries.co.uk/l1/p281-dampness-saltpetre-condensation.html

Hey Kriti, The wardrobes are white so any color/shade will match with it. so you can go for louvers paneling, add a mirror, carved limestone or you can go for cheaper option by adding beading with cnc corner to give a european kind of look. You can check that out in our projects for reference. Even a tropical or any other themed wallpaper might look nice based on the aesthetics of the room.

These are authentic bricks in the construct. You can buy brick cladding from almost any tiles shop or use brick texture, but let me give you a headsup, they wont come anywhere close to original bricks, unless you go for a high end one
