Sliding cover?

This week I masterminded a simple pulley system to make a light dim itself. (ok, with the help of my engineer brother and the techs in the shop). Then i watched this video and it put me to shame. This home makes me think that really anything is possible.

A man in Suffolk UK built this incredible glass house, with a slide-over cover, it will blow you away! and the design is quite nice. I especially appreciate how he maintained the shape of typical Suffolk homes, and also I think the important part is that his brief wanted to have the house value the surroundings and not just be for the sake of being.
