Tax planning for Long term Capital gains over 1.3 crores from house property.

Hi,

I have an office which am planning for sale. 

Purchase price: 17 L

Sale price:   1.5 cr

Depreciation has been claimed for certain years so I guess that rules out indexation.

I don't want to buy another house property and would prefer to invest in Section 54 bonds. However there is max limit of 50L I think.

Can someone suggest a solution / options ? 

Thanks & Regards

CA
