The direction of your main windows decides how much sun and heat you get through the day. North, south, east, west – sabka apna mood hai. For example, east-facing windows bring pleasant morning light, while west-facing ones can blast strong afternoon heat.
Knowing this helps you plan curtains, blinds, furniture placement and even wall colours. A very hot west-facing room might need thicker blinds or lighter colours to bounce heat away. A low-light north-facing room might do better with softer shades and clever artificial lighting.
Plants, too, depend on this. Sun-loving ones get the bright spots; shade-lovers stay away from direct beams.
Instead of being surprised later—“Yeh room itna garam kyu rehta hai?”—you walk in already understanding what kind of light behaviour you’re buying.
