This contemporary home interior project is titled “Hei - Sei ” . Design concept focuses on a tranquil and harmonious home interior inspired by the Japanese aesthetic principle of "Hei Sei." With a neutral palette and strategic pops of color, we created a space that fosters calmness, relaxation, and a sense of well-being. Embracing minimalism ,simplicity, functionality, and visual clarity. We prioritized clean lines and decluttered spaces to create an uncluttered and calming atmosphere. Strategic placement of accent colors added depth and visual interest to the spaces. Carefully selected hues that complement the neutral palette has been sparingly used in decor elements such as artwork, and accessories. The balance and symmetry in furniture and decor arrangement fosters a sense of order and harmony. We ensured visual equilibrium by considering proportion and visual weight.
