Definition
Before the RERA act enforced "Carpet Area," Super Built-up Area was the dominant metric in Indian real estate sales. It calculates the apartment's primary Built-up Area (the flat itself and its walls) PLUS a proportionate mathematical share of the building's common amenities—such as the lobbies, staircases, elevator shafts, clubhouse, and corridors. Because it inflates the square footage, it makes the "price per square foot" appear lower and more attractive in marketing.
Practical Example
A developer advertises an apartment at ₹5,000 per sq.ft with a "Super Built-up Area" of 1,500 sq.ft (Total Price: ₹75 Lakhs). In reality, the actual internal "Carpet Area" the buyer can live in is only 1,000 sq.ft. The extra 500 sq.ft they are paying for represents their 5% fractional ownership of the building's massive luxury lobby and swimming pool.
Application in Superwise
Navigating different area metrics is crucial for developers. In the Superwise Sales & Unit Master module, the developer defines the "Loading Factor" (e.g., 30%). The system automatically calculates that a 1,000 sq.ft unit (Carpet) corresponds to a 1,300 sq.ft unit (Super Built-up). This allows developers to seamlessly generate sales invoices based on older Super Built-up norms while remaining legally compliant with RERA's strict Carpet Area reporting.
