West-facing 20×40 ft house plan in Chennai
A 20×40 ft plot (800 ft², about 1.8 cents) with the road on its west side. West-facing plots are perfectly workable in Vastu (many traditions rate it favourably for specific households) and often a little cheaper than east or north — the trade-off is the evening sun.
Where the rooms go on a west-facing plot
Vastu corners are compass-fixed — what changes with facing is where they land relative to your road. On a west-facing plot the road is the west side, so:
| Room | Vastu corner | On this plot |
|---|---|---|
| Pooja room | North-east (Ishanya) | rear, toward the north |
| Kitchen | South-east (Agni) | rear, toward the south |
| Master bedroom | South-west | front, toward the south |
| Staircase | South or west side | front, toward the south |
These are the same placements Plot2Plan's design-checks card scores a generated plan against — advisory guidance, never a legality rule.
Sun, entrance and the west road
The facade takes the full western evening sun — Chennai's hottest. Deep setbacks, verandas or a garage on the front face earn their keep; bedrooms are best kept off the west wall.
The main door opens on the west (road) wall. Vastu guidance for west entrances favours the middle of the wall or its northern half.
Setbacks & buildable area
Facing changes the orientation, not the by-law numbers: side and rear setbacks stay 1.5 m, the front setback (on the west wall) depends on the road width, FSI stays 2 and the height cap 12 m. On a typical 30 ft road that leaves roughly a 10.2×25.2 ft footprint (~256 ft² per floor) and up to 1,600 ft² of total built-up area. Full road-band tables are on the 20×40 plot guide.
