I also figured out an alternate way/cheat as per suggestion from Keet. I will share that too shortly. Cheers !

This is the one how I tried.

Created a wall in three parts and copied it as furniture and managed somehow but goofed up a bit on the corner angles and texture. Its not perfect, I just wanted to share what I did. Finally I am going to make it how Keet suggested with Kelvin's tile and corner model.

Thanks guys.
