A narrow room?

My next project is to turn a long and narrow living room to look spacious and light. This client has a beautiful garden with a large pool. My plan is placing a huge mirror opposite the big patio slidning doors - this will bring both natural light and bring the beautiful greenary and pool into the living room but also the the mirrors will appear to create more space and reflect a lot of light into the room. The first picture is from my Marbella apartment which is very narrow and long so these huge mirrors didmagic to the room. Can´t wait to share the result with you!
