First, I would ask the builder to give you the dimensions of the furniture used in the plan. Since they've already done the legwork-you will know which pieces will fit. Many times folks go the the furniture store and end up with a huge sectional and it over powers the room. Second, just get what you love! You have to live there. Start to create an idea book in Houzz. You'll start to see a pattern. Then just find a sofa like the one in your pic that is in your price range. Just keep repeating until you have all your pieces. Same thing with wall decor (which I would do last). Have fun!

add a mirror in each niche, use a nice wallpaper behind it and simple curtain blinds will make it interesting. Use a highlight paint on ceiling to match with wallpaper

hi! you can go for a profile table along the sofa horizontally in middle of the both areas. you can have small width partitions of fluted glass. an open shelving unit can also be a good option. thanks!

Hi Susheela, you can opt for a RFID card lock or fingerprint lock system for a profile shutter door. Kindly check out Dorset and Yale door locks for the same.
