Summer Hill, a hilltop pocket of Khandala just off the Mumbai-Pune Expressway, is where Hiranandani Communities has built Mount Alterra, a villa-plot development that carries the same township philosophy the group has applied in Mumbai, Thane, Panvel and Chennai. Perched 518 meters above sea level, Mount Alterra by Hiranandani Communities offers an exclusive retreat amidst the lush mountains of Khandala, just off the Mumbai-Pune Expressway. The setting places a Hiranandani buyer inside one of Khandala's established residential pockets rather than an unproven new address.
Summer Hill is one of the prime locations to buy a home in Khandala, with 5 residential projects. Within that small cluster, Hiranandani's presence gives the locality a scale and institutional weight that smaller independent villa plots around it do not carry.
Hiranandani's interest in a hill destination like Khandala is consistent with how the group has expanded since its founding. When Dr. Niranjan Hiranandani and Surendra Hiranandani started building in 1978, the idea of a self-sustaining township with schools, hospitals, retail, offices, and residences woven into a single master plan was not how Indian real estate thought. That approach first proved itself at scale in Mumbai: ask anyone in Mumbai real estate to name one project that permanently changed what luxury residential meant in this city and the answer is almost always Hiranandani Gardens Powai, a 250-acre township that arrived in a part of Mumbai considered peripheral and made it aspirational.
The group repeated that pattern at greater scale in Thane, where Hiranandani Estate Thane was the ambition fully realised, and at 375 acres, it is one of the largest integrated townships in the Mumbai Metropolitan Region. It has since carried the same model to Navi Mumbai, where Hiranandani Fortune City is a 588-acre integrated township in Panvel, Navi Mumbai, developed by Hiranandani Communities, one of India's most established township builders with four decades of experience, and to south India, where Hiranandani Parks is a massive 360-acre integrated sports township, located just off Oragadam junction in south-west Chennai. The developer has also moved into financial-district infrastructure, having completed Hiranandani Signature, India's first IFSC tower at GIFT City, Gujarat. Mount Alterra in Summer Hill sits within this same body of work, applying the group's township discipline to a hill-station villa-plot format rather than a high-rise or mixed-use campus.
At Summer Hill, the group has laid out plotted development rather than apartments. Unit details at the project include villa plots in Villa plot Area of 750 Sq.mtr and 3100 Sq.mtr, with pricing starting from 1.28 Cr onwards. The development is planned around recreation as much as residence: a clubhouse that lets residents host gatherings, a gymnasium and yoga centre, and a swimming pool with a pool deck sit alongside the group's own progress note that it has commenced development of a 9-hole golf course at Mount Alterra, Khandala.
Location context that Hiranandani itself cites for the project includes its position equidistant from the MCA stadium located in Pune and the upcoming international airport at Navi Mumbai, while immediate landmarks around Summer Hill include Duke's Retreat and Khopoli.
Khandala's appeal to a Hiranandani buyer rests substantially on the Mumbai-Pune Expressway. Drive time from Mumbai's Bandra-Kurla Complex is approximately two hours and fifteen minutes off-peak, while from Pune's Koregaon Park or Kalyani Nagar it is under ninety minutes. That two-city reach is precisely the demand base the group's other townships along this corridor, including Fortune City in Panvel, are also built to serve, and infrastructure upgrades are compressing it further: the Missing Link Project connecting Mumbai with Pune is expected to reduce travelling time to Pune by 30 minutes by bypassing the Lonavala Ghat, with completion expected in 2026. The Navi Mumbai International Airport, now operational since December 2025, adds a second access point for buyers travelling from further afield.
The plotted and villa segment around Khandala has moved into a distinctly premium bracket. Premium luxury villas in Lonavala typically range from INR 12,000 to INR 18,000 per square foot, with exceptional properties commanding rates up to INR 25,000 per square foot based on location and views, and property values in the region's premium segments have consistently outperformed other luxury markets, with average appreciation rates of 12-15% annually over the past five years. Supply constraints reinforce that trajectory, since Western Ghats topography, ecologically sensitive zone regulations, and forest department restrictions have meaningfully constrained luxury supply across Khandala and Lonavala. For a buyer evaluating Hiranandani's Summer Hill plots, this combination of a branded, amenitised township format inside a supply-constrained hill address is the core of the investment case, distinct from the group's larger urban townships in Powai, Thane, Panvel and Chennai but built on the same underlying model.
