30 x 40 house plan, south facing, as per Vastu
South-facing plots are the facing classical texts are most cautious about, and also the one where correct layout matters most.

What fits on a 30x40 plot
With the standard setbacks this planner uses — 4 ft on the road side and 2 ft on the other three sides — a 30 × 40 ft plot leaves a buildable rectangle of 26' × 34', or about 884 sq ft of the 1,200 sq ft plot.
The generated layout uses 884 sq ft of that as ground-floor built-up area, of which about 224 sq ft is open living and dining space.
Setback rules come from your local municipal byelaws — change them in the planner and every figure above recalculates for your plot.

| Utility | 7'4" x 4'3" | 31 sq ft |

Vastu notes for a 30x40 south-facing plot
A south-facing 30x40 plot's entrance works best in the southeast third of the south wall — placed carefully, this direction is workable rather than something to avoid outright, which is a common misconception. The real work on a south-facing plot is making sure nothing else compounds the entrance direction: the kitchen stays in the southeast as usual, the master bedroom in the southwest, and the northeast is protected exactly as it would be on any other facing. Where south-facing plans genuinely need more care is the entrance sequence itself — on a 30-foot-wide plot, a short, direct entry straight into the living space is usually better than a long internal corridor, since classical guidance treats a south entrance as needing a clean, unobstructed threshold more than most other directions do.

30x40 south-facing plans: common questions
Is a south-facing house bad according to Vastu?
Not inherently — it's the facing that needs the most careful entrance placement, but a well-planned south-facing home is entirely workable.
Does the main door position matter more on south-facing plots?
Yes, more than on other facings — getting the entrance into the correct third of the wall matters more here than the general rule of thumb for other directions.
Can I still get a good Vastu score on a south-facing 30x40 plot?
Yes — south-facing plans regularly achieve strong scores when the entrance and core rooms are placed correctly; the facing itself isn't a ceiling on the outcome.
