Hi Sppirya, Did you use glass flooring in your space? Looks great here:

Nowadays builders from Delhi and NCR are shifting to places like alwar and bhiwadi for apartment construction, as delhi and NCR are not vacant for construction. So, the building materials charges have increased comparatively. Even if you save 5000 or 10000 in design fee, it won't make any difference. As, ultimately you have to bear contractor charges and building materials.

my house is also going through the construction stage from past six month's I used clay red bricks instead of using cement blocks & bricks as my architect & structure engineer both adviced red bricks keep 3 to 4 degrees temperature down in summer & plastering of wall is more convenient & long life on red bricks, comparing to cement bricks , cement bricks are easily available nice in size ,shape, strong & sturdy hence there is very low waste comparing to other materials

Sajeesh, From our experience, Century and Greenply are good. But they are atleast 20 percent costlier. Kitply is also reliable brand. Anyways always buy from company authorised distributors. There are a lot of duplicates being sold for plywoods. You can expect 80-90 per sqft for a decent ply. Cheaper ones would start at 45 per sqft. Thanks, Nitin Cornerstone Designs Bangalore.
