Interior designer and Vaastu consultant Sanjay B Navgire works across spatial planning…

Interior design and Vaastu consultancy represent two distinct but overlapping professional practices that engage with how human beings inhabit and experience space. The first concerns itself with aesthetic and functional arrangement; the second draws from an ancient framework of spatial philosophy. When these approaches intersect in a single practice, they create a particular lens for seeing how architecture and furnishings shape daily life. What Vaastu actually is Vaastu Shastra is a Sanskrit term referring to a body of architectural and spatial knowledge that developed over many centuries in South Asia. It concerns itself with the relationship between built environments and the people who occupy them. Unlike Western design theory, which tends to separate aesthetics from metaphysical concerns, Vaastu integrates principles about orientation, proportion, material selection, and spatial flow with philosophical ideas about energy, balance, and harmony. The term is sometimes translated as "the science of architecture," though "philosophy of building" captures its character more precisely. Vaastu emerged from Hindu, Buddhist, and Jain traditions and appears in texts dating back millennia, though practitioners continue to interpret and adapt its principles. How spatial planning draws from tradition Interior designers who engage with Vaastu principles approach spatial planning differently than those working within purely contemporary frameworks. They consider cardinal directions as meaningful: where a kitchen sits in relation to north, south, east, or west carries significance in Vaastu thought. Room proportions, ceiling heights, the placement of entrances and windows, even which materials face which directions, all form part of the calculation. A designer working in this tradition sees the floor plan not merely as a container for furniture but as a system with inherent directionality and purpose. This requires thinking about space holistically, as something that influences the quality of time spent within it. Materials and form in context Vaastu design considers the intrinsic properties of materials in ways distinct from contemporary minimalism or maximalism. Wood, stone, water, metal, and earth are understood to carry particular characteristics. An interior designer informed by these principles might select copper not for trendiness but because of its properties as understood within the tradition. Similarly, the proportions of rooms, the curve or angle of architectural elements, and the visual weight of furnishings all respond to ideas about balance and flow that predate modern interior design schools but inform contemporary practice. Why it matters for design thinking Understanding Vaastu and traditional spatial philosophy matters because it expands the vocabulary available to designers and inhabitants alike. It suggests that how we arrange our homes and workplaces connects to how we feel and function within them, an idea
