Dear client,
We proposed to access to your deck through a beautiful "serliana" windows in your living room, so you can enjoy the view of the surrounding nature from your home.
The "serliana" windows was an invention of Andrea Palladio architect during the Renaissance:

The use of this particolar windows gives to your space a classical and elegant character.

We place a big skylight in the center of the living room to change the intensity of the interior light and to give simmetry to the space.

This design gives you a nice idea of how you could utilize the space you have. Of course you can move forniture around and we would be happy to elaborate new ipotesis for you and continue the second part of your project.
