Construction assumes a new meaning with Valliappa Real Estate – The Sona group’s subsidiary. The group’s foray into real estate began with construction projects primarily focused on the group’s projects in the 1980s - Sona Tower. Today Valliappa Real Estate has evolved into a full-fledged construction company. Successfully completing a number of commercial and residential projects, the company overlooks two prestigious projects – Sona Heights and Sona Vistaas.
