The calculations are broadly excepting the following:-

1. For approvals it might cost you Rs.200-400/- a sq.ft including the sanction of plan, issuing of completion certificate, without which the future resale of the project becomes difficult.

2.The road width decides the Floor Space Index (FSI) supposing on a 2400sq.ft. land if it 30' road you may get 1.5 i.e. you can construct 3600sq.ft. depending on the frontage of minimum 50' (set back on both sides would be 7' and front and back would 10-15' minimum.

3.Escalation cost on construction should be considered anywhere between 15-20% during the time of construction. You have taken the least of the cost and it should be considered anywhere between Rs.1600/- to Rs.1800/- per sq.ft. this is for quality construction.

4.Builder and the timeline he takes for construction is between 12 - 18 months and interest part for those period should also be considered.

4.Most of the roads are narrow in Madipakkam excepting one or two broad roads. Providing Septic Tank is big hassle as Drainage system is yet to operational for the entire madipakkam.

Taking into consideration all this factor and also the ground cost of Rs.55- 60 lacs and between Rs.65 lacs - Rs.70 in Ramnagar (madipakkam) little outer pheripheral of madipakkam and near to Velachery overbridge the cost should be fine.
