Vastu Shastra is the traditional Indian science of building and orientation. Its core idea is simple: a structure is placed within the directions, and each direction is associated with an element and a presiding deity. A plan that respects that arrangement is considered harmonious to live and work in.
The Vastu Purusha Mandala — the grid on which a plot is conceptually divided — is the starting point. North-east (Ishanya) is associated with water and is kept light and open; south-east (Agneya) with fire, which is why the kitchen is placed there; south-west (Nairitya) with earth and weight, suited to the main bedroom and heavy storage; north-west (Vayavya) with air, suited to guest rooms and movement.
A consultation looks at the plot shape and slope, the entrance direction, the position of the kitchen, water sources, toilets, the staircase and the placement of beds and the puja room. Commercial spaces are read the same way, with attention to the seating of the owner and the cash position.
Corrections are kept practical. In most homes nothing needs to be demolished — the remedy is a change of use for a room, repositioning of furniture, correcting a water source, adjusting light and colour, or a Vastu Shanti puja before moving in. Demolition is suggested only when a structural fault is genuinely serious.
For families building new, it is far easier to consult before the plan is finalised than after construction. For an existing house, a visit or a set of clear photographs and a dimensioned plan is enough to begin.
