FAQs – Greenest Residential Projects in Kolkata

- Are green projects in Rajarhat more expensive than regular ones?
While the initial purchase price might be 5–7% higher due to advanced construction materials, the long-term maintenance costs are significantly lower due to solar power integration and efficient water management systems.
