the glass at the front of the home in your picture at your price is at least 2 grand, maybe more, there´s 4mt wide and at least 4mt high, there´s 16mt2 and the 2 panels on each side, there´s another 4 to 5 mt2, and obviously the front at the top, it´s specially cut to fit angles.
so there´s your 1500 even at your prices, but in reality, the front glass alone is as I say, at least 4 or 5 grand of glass and fitments.

now the windows and double glazed doors around the side and rear, when you have finished your project without glass, then we can re-evaluate this
