What a per-square-foot package quietly assumes.
A package is a rate multiplied by an area. Both halves carry assumptions, and the assumptions are the actual product being sold — not the rate.
Published interior costs in Hyderabad run roughly ₹1,200 to ₹2,200 per sq ft, and that spread is not sloppiness. It is the honest range across board grades, hardware series and finish tiers. A package picks one point inside that spread, fixes the specification that goes with it, and then applies it to every home that signs up. Which means a package is not a discount. It is a specification decision made on your behalf, before anyone has seen your flat.
Three assumptions do most of the damage.
The area basis
A rate is meaningless until you know what area it multiplies. Carpet, built-up and shutter area are all in use, and they are not close to each other. The same rate applied to built-up rather than carpet area turns a ₹15 lakh expectation on a 1,500 sq ft flat into ₹22 to ₹25 lakh — no dishonesty required, just a different denominator. This single variable moves the total more than any material choice you will agonise over.
The exclusions
Painting, false ceiling, electrical changes, plumbing shifts, countertops, appliance cut-outs, loose furniture, society deposits. Some packages include some of these. Almost none include all. Each excluded item is legitimate to exclude — provided it is written down — and each one arrives later as an addition to a number you had understood to be final.
What a square foot contains
A wardrobe quoted at a flat rate per square foot is priced for shelves, because drawers cost more to build than shelves. Ask for drawers inside that same square footage and either the price moves or the drawers do not appear. A rate that absorbs the internal configuration has to assume the cheaper configuration to survive; that is arithmetic, not malice.
