What did you eventually decide on doing with the space? Feel free to upload some photos! :)

how can i do interior decorate for my boutique shop said the measurement plz suggest me...

Here's the explanation of how to know if you have room. Your total inches is 100. Assuming you have cabinet on each side, subtract 25.5 for each side (the depth of your countertops) and now you have 49" left. You need 33-48" on EACH side of the island. If you used a 12" deep cabinet for your island instead of the normal 24" depth, take the 49" and subtract 12 (but you will have some counter overhang) and you have 37" left. Divide 37 by 2 and this gives you only 18.5" of space on each side of your island - not nearly enough space to move around or to open doors/drawers/appliances.

I really do think you need someone in your locale and on site to give you the best estimate
