Where the terrace faces the reservoir bund, that parapet is not a working edge. Ladders and rails stay on the house side. We do not reach onto the bund, and we do not state a clearance in metres. The visit from Madipakkam is free.
The row sits on the house side of the slab. That bund-side parapet is left as a walk, not a rail line. A house that does not face the bund is an ordinary survey.
A parapet that looks onto a station yard is the Egmore case. The corner a lake leaves by is the Villivakkam case. If the lane floods and delivery has to wait, that is the Keelkattalai case, and it does not change the layout. A hill on the next plot is the Pallavaram case. A high campus wall is the Kodambakkam case. City-wide module choice is on panels for a Chennai home.
We mark the side that faces the bund before any row is drawn.
A full plant for a Chennai home is described on the solar installation page. The visit is free, and nothing is ordered until you ask. The desk is open monday to saturday, 9:00 am – 7:00 pm.
