Khalanga Heights introduces Dehradun’s first green residential landmark, where refined living harmoniously blends with the serenity of nature. Rising 120 meters above the city, yet located barely 1.5 kilometers from the urban center, the development offers residents a perfect balance — an escape from city noise without losing city access. Spread across an expansive 1.48 acres site, the project is designed around biophilic architecture, ensuring maximum natural light, ventilation, and greenery throughout. Developed by Onetara Realty, this under-construction masterpiece comprises 167 thoughtfully crafted apartments across two elegant towers. Perched in Sunderwala, the project delivers resort-style living — fresh mountain air, panoramic valley views, and a lifestyle that feels rejuvenating every single day.
Khalanga Heights sets a new benchmark in sustainable luxury by introducing Dehradun’s first eco-friendly residential tower. Its biophilic design embraces natural elements, creating an environment that promotes health, harmony, and holistic living. Residents can enjoy a 700-meter jogging track shaded by greenery, while the project’s resort-inspired amenities bring everyday leisure within reach — a cascading pool, spacious banquet hall, fully equipped gymnasium, indoor gaming rooms, and a dedicated arcade zone. Thoughtful community spaces, including a well-stocked library and family lounges, reflect a lifestyle centered on comfort and connection. To ensure ease of movement and safety, 25-foot-wide internal roads run through the development, supported by 24x7 CCTV surveillance and controlled entry points. Every design detail, from the open courtyards to the landscaped podiums, underscores Onetara Realty’s commitment to modern wellness-driven architecture.
Khalanga Heights occupies a prime hillside location along Harchawala Road, Sunderwala, one of the least polluted zones of Dehradun. Sitting 120 meters above city level, the area enjoys temperatures up to 5°C cooler than central Dehradun, offering a naturally comfortable climate all year round. Despite its tranquil surroundings, the development is just 1.5 kilometers from the main city, ensuring effortless connectivity to key landmarks. Within a 2-kilometer radius, residents can visit six revered temples, fostering a deep sense of spiritual balance. The project’s proximity to the lush Sal Forest and the breathtaking Mussoorie Hills further enhances its natural charm.
