Long term capital gain on sale of residential house

The builder billed me for 8 lakhs towards (i) Advocate Fee; (ii) Club House Membership Fee; (iii) Maintenance Deposit; (iv) Charges For Electricity & Water; (v) Modification Charges, and I paid this amount along with Land & Construction cost.  

My question is "Will this 8 lakhs be considered as cost of the property for capital gain purpose?"

Please also suggest the safe investment ( a part of the sale proceeds) other than house property.
