You've purchased two EWS plots and built on them over seven years ago, with Panchayat approval. You're wondering if you can merge these plots and if there will be future issues when selling. While the definition of an EWS family includes multiple properties, owning separate plots under EWS can be problematic unless they fall within specific size limits (under 100 sq. yards or 900 sq. ft combined). It's advisable to consult a local lawyer with all your property documents to understand the implications for merging and selling.
