Elion — pronounced ee-lee-on — is the House of Sawansukha's first venture into real estate, carrying eight generations and over 250 years of the family's legacy into a full-floor residential address on Nandalal Basu Sarani (formerly Little Russel Street), one of central Kolkata's quietest yet most connected streets. The name itself is a deliberate fusion — elephant and lion — built to signal scale and strength.

The building runs on a strict One Floor–One Flat concept: the ground and first floors house a luxury retail showroom, while the second through eleventh floors hold just ten full-floor apartments — one per floor, each roughly 4,400 sq. ft., configurable as 4 BHK or 5 BHK, with the option to convert into a duplex or triplex. Every residence opens on multiple sides for cross-ventilation and natural light, anchored by a grand 28-ft south-facing balcony with city views and a private open terrace deck on each floor. The building is IGBC Gold certified, one of the few green-rated luxury addresses in this part of the city.

Elion sits on Nandalal Basu Sarani (formerly Little Russel Street), tucked into the same central pocket as Shakespeare Sarani and Loudon Street — walking distance from Maidan and minutes from Park Street, with the city's best-known hotels, malls, schools, and hospitals all within a short radius.
