Master Renovation

A good friend's mom recently asked me to help her fix her house....her whole house! Luckily, her husband is a contractor and is completely down with doing the work! While the fun stuff (furniture, fabrics, accessories) will come later, here is an image of my proposed idea for structural changes to the back half of her house!

Currently she has a really long an narrow room adjacent to the master that acts as a study and music room. I am proposing two different ideas, both of which will make the spaces more functional and will add value to the house!
