Running two business from same office space with different GST number

Dear Sir

I have a huge office space which I am not using fully. I am thinking of partitioning the space and run two businesses. It will have 2 different GST numbers. The only catch is the entrance is common.

If I put a partition in between and put GST number sticker on that . - will it help in identifying that as separate business entity

Regards

Taher
