2. If association not agree , then you can file a suit before the court for directing the association to allow you to carry that work , or you can take approval from BDA.

3. Yes

4. Yes

5. Yes, 

Dear Client, 

                  The Association can legally stop you from making such renovations,however, making modifications in your own villa is not illegal. You can try to obtain approval from BDA and if unable to convince them, you may also consult a lawyer specializing in land or real estate matters.

Thanks & Regards

Any villa owner has the right over the property as described in the title document. The additional land should find a place in the title document and should not have been shown as part of the 'common area' in the approved BDA plan. The association has a right if the additional land lies within the 'common area'. Please check these facts thoroughly and seek the advice of a local lawyer to proceed further.

1. If you desire to have the construction restructured then you can apply for fresh approval with the BDA, let them give a reply for the reasons rejecting your application or approve the same.

2.  You are to confine to your interests alone.

3. The other owners are not into the proposed structural change hence they would object to your proposal and may not cooperate with you

Get approval of entire block consisting of all units 

if other owners don’t sign application get plan approval for your villa 

You can approach court in this matter

Yes you can get approval

Please have all the documents in your possession including the BDA approved sketch and approval letter examined by a local counsel and seek his advice.
