Houzz is primarily for residential buildings but here are some images that might give you an idea of maximising space and light You basically want to keep a level of space and light so white or a soothing pale blue can work if the work is stressful. Good lighting and good natural light. Perhaps your management box in the center as four squares and slightly raised so you can see out the windows but also allow your staff to benefit. A rest and relaxation area for some breaks and a kitchen and toilets.

This layout is according to vastly but I need expert advice on this Can it be modified to look better ant how

This is your plot size. Give the directorial drawing for the roads and the main entry as per the North direction

Hi Kolli, This is an amazing corner to come up with different designs. I am excited that there are three!!! 1. You can go for open bookshelf loaded with photo frames, lamps with a ladder to make it a mini library. 2. You can have an inbuilt seating coupled with bookshelf and lightings. 3. Dining room shelf and mirrors to fill the spaces. 4. If you have interest in music then make it a music corner. I am adding photos for your reference. (from internet) This blue piano table is my personal work. Rest are taken from internet. Please feel free to call for any other help! Cheers, Souls & Blossoms
