Firstly, one can play a lot with furnishings if you are staying in a rented apartment. those white walls are nothing but a clean canvas and you can really use colors through your furnishings like cushions , upholstery, curtains , rugs etc to add colors . Secondly , instead of wall shelves etc add small side tables on emptycorners you get etc which gives you platform surfaces to display your nick knacks.. You get many freestanding display shelves online and in market where you don't have to use screws in wall. :)

Hi Mr. Narayansingh, You can go for some stone cladding on the exterior surfaces of the wall. You can wooden doors and wooden framed windows. You can use grey colour textured stone cladding in the half/few portion of the elevation. Thanks

Hi Nikita, First and farmost, you have very beautifull coushion on sofa, from where you buy it? You can check the videos of Small budget Big makover first session series in youtube. In One such house in Gujarat, Muninder and Bishakha coloured the old sofa set with whtie (The sofa is like yours) and changed the centre table. Interestingly, the family also had your kind of sofa set and they also want some modern style. The architect duo did not changed the sofa, just changed the colour. Yes I found it in youtube. it is the house of Setu Upadhyay. the link is https://www.youtube.com/watch?v=85GNhyLeVnM Another suggestion is that you have many tables on the room. You can drop few chairs and opt for a single centre table

Romney, First thing is that requirement of light is measured in lumens. Secondly , you will have to look at the room requirements , colors on the wall, furniture, flooring etc. Even the temperature (i.e. warm or cool) of the lights is very important. Depending on your requirements an appropriate suggestion can be made. Please share some room pics along with query. Thanks, Nitin Cornerstone Designs, Bangalore.
