Two ways. Kelli's suggestion is one. Frame the windows with wood and build the greenhouse around them. Or build the greenhouse out of wood with openings for the windows.
It is very important to make a good foundation and solid walls. I think the best variant is to hire a supervisor who will be able to advise you on this matter and regarding the choice of materials and work. Some years ago we were searching for our new housing and we decided to construct all ourselves. But the specialist who helped us, advised using https://houseseek.com.au/ where you can choose ready-made housing for the more affordable money.

This greenhouse is stunning, I want one too :). I was looking for nice models of greenhouses for my elderly mother and I like very much what I see here. With my dad gone she feels very lonely during the working days of the week when I barely have time to come by. I do my best in order to spend as many weekends as I can with her but I still think that she still needs something that will keep her busy. She is a huge fan of flowers and I think that such a greenhouse will make a perfect gift, plus it looks very good as a decoration too.

You will need to establish a waterproof, level, and durable supportive base for your greenhouse, so that the building itself is off the ground.
Without this being in place first, any structure that you try to create will soon sink, shift, rot, and disintegrate.
