Capital gain tax save

Namaste sir 

I'm Narahari from Bangalore,  I had sold my plot for Rs43 lakhs and deposited in capital gain account in bank. 

Now I'm purchasing 15 years old flat for Rs 37 lakhs. 

The remaining 6 lakhs can i use to modernize my new house like 

New wardrobe 

Change of floor titles 

Change of rest room fixtures 

Painting and other miscellaneous 

So to avoid capital gain tax 

Please advice 

Regards 

Narahari
