Keep it white its beautiful ,just add a few planters on top of the columns with red Geraniums and paint the front door black

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!

i am not sure whether there is an app like this. If you can work in photoshop, you can take the texture and images from google and apply. Or you need to get an architect to design an elevation for you. We could also help you in that but it would be chargeable.

For the wall in the balcony I have shortlisted two stones A) Black leather finish granite B) Grey William granite. I am posting pictures of both. What can be pro and cons as I am looking for the exteriors wall only. Further for there will be window and steel/glass grill at wall of balcony so not sure whether book match pattern of grey William stone will work or not. I request whoever reading this to suggest which stone will look better at my elevation wall. Thanks a lot for reading this. Looking forward to get some positive suggestions.
