1. Contact Local Real Estate Agents: Reach out to real estate agents who specialize in the Yamuna Expressway area, specifically Sector 20. They will have the most up-to-date information on available plots in Pocket G.
2. Explore Property Websites: Visit property websites that focus on the Yamuna Expressway region. These platforms often list various plots for sale and provide search filters to help you narrow down your options based on plot size, location, and other criteria.
3. Consult Real Estate Developers: Check the official websites or contact real estate developers who have ongoing projects in Sector 20. They may have 300 sqm plots available or can provide information about upcoming projects that align with your requirements.
