Plot Dimensions (Your Input)
Area = ((Side A + Side C) ÷ 2) × ((Side B + Side D) ÷ 2) = ((50.0 + 50.0) ÷ 2) × ((70.0 + 70.0) ÷ 2) = 3,500.00 sq.m
Required Setbacks
Plot and Setbacks as a Drawing
Take the plot, its roads, the setback line and each scenario's building into CAD or Google Earth. Every part sits on its own layer, in metres, with the building heights set, so the drawing starts from this report's figures.
This plot was entered as side lengths, which gives its shape but not where it lies or which way is north, so a map file would only be a guess. A KML is offered when the plot is read from a KML, KMZ or GeoJSON file at the plot step.
High-Rise Feasibility (>19.5m)
Eligible for High-Rise Development
All requirements met for buildings above 19.5m height
Planning Notes

- Staircases: at least 1.6m wide with a 1.6m mid-landing, one for every 6 classrooms, continuous to the terrace, no more than 22.6m to reach from any part of an upper floor, and a ground-floor exit at least 2m wide and 2.1m high opening to open space (Annexure XV)
- Terrace parapet at least 1.0m high and 23cm thick (Annexure XV)
- A kitchen in the school premises must not be close to the classrooms or the student toilets (Annexure XV)
- Number of floors: as the National Building Code 2016 provides (Annexure XV item 2)

- Security deposit: 50% of the infrastructure and amenity charges, refundable without interest, returned when the building is completed as approved (Rule 37 J)
- A high-rise is possible here (Rule 39), but on a road of 12m it allows FSI 2.0, no more than the building of up to 19.50m, so that building is planned

Comprehensive Zone & Overlay Analysis
NOCs & Clearances Required (TNCDBR 2019)
- Patta/Chitta in applicant name
- Not government poromboke land
- Not under land acquisition proceedings
- Not affected by flood notification
- Not under Land Ceiling Act
- Original ownership documents verified
- Court cases pending on property (if any)
- Title disputes resolved
- Encumbrance issues cleared
Manual Verification Required: Some NOCs require verification based on actual property documents and local conditions. Consult with local authorities for definitive requirements.
Location-based checks (HT lines, water bodies, CRZ, airport, eco-sensitive zones, etc.) are computed from the property's mapped coordinate against third-party and government GIS data, so the distances and zone boundaries shown are indicative. Confirm critical findings on-site or with the concerned department.
