Wow! Super lucky to have the luxury of extra space! I can't tell you what to do exactly with your space, but I would suggest to change out your garage door. I love this idea, and I would really like to utilize it when I build! If I can't have it...I'll just be happy that someone else is enjoying it in the meantime!

Photos of the exterior would be helpful.

Hello Neetu, UPVC, is a polymer material. Its windows are good for window frames and shutters. Usually they are used with toughened glass panes on the exterior areas of the homes. They will offer you long life and low maintenance as a product. Thanks, Nitin Cornerstone Designs Bangalore

Hi Deepak, Neighboring noises can be annoying, especially night. I would advise the same, go for u-PVC windows, that will help in maximum noise reduction. As I can see in image, a full-length curtain indicating probable full window or door. You should go for u-PVC window/door for that too. The noise will be reduced to a minimum. -Thanks, -Neelam -Lines and Profile
