Nadia House by Arrjavv is a 27-apartment, single-tower development at 2 Bright Street in Ballygunge, diagonally opposite Modern High School. At G+34 and roughly 148.5 metres to the top of the structure, it is one of the tallest purely residential towers in the city — and, on a per-unit-count basis, one of the most exclusive: 27 apartments across 35 floors means, for most of the tower, one apartment occupies an entire floor.

That "one floor, one flat" arrangement is the whole premise of the building. Each residence is a 5 BHK sky villa of approximately 7,500 sq ft, with a 4-metre floor-to-ceiling height, two servant quarters, and a private open terrace — proportions that put it in the company of the handful of buildings in Kolkata built at true skyscraper floor heights, rather than standard residential slab construction. Access to every floor is effectively private, since there's no neighbour sharing your landing.

The land beneath it is the other half of the story. Nadia House sits on approximately 76 cottahs (1.26 acres) — a genuinely rare assembly for a single-tower project this close to central Ballygunge, where land this size more often gets split across two or three buildings. Arrjavv has instead built one slender tower and spent the rest of the plot on amenity: a 20,000 sq ft clubhouse, a triple-height 7-star entrance lobby, a rooftop infinity-edge pool with a 360-degree skyline view, and a rooftop sky lounge — all shared across just 27 households.

Nadia House sits inside Ballygunge's most established residential pocket, on Bright Street near Mayfair Road — a few minutes' walk from Modern High School, which sits diagonally across the road.

Education. This is arguably the single strongest schooling cluster in Kolkata within a genuinely short radius: Modern High School immediately opposite, and South Point, Patha Bhavan and Oxford House all within roughly 3 km. For a family buying a home around a child's schooling years, few Kolkata addresses offer this concentration.

Healthcare. Apollo Gleneagles and Ramakrishna Mission Seva Pratishthan are the nearest major hospitals, with a further cluster of specialist eye-care centres in the immediate neighbourhood.
