interiör

Interiør refers to the interior of a building or room, and to the field that plans and decorates those interiors. The term covers spatial layout, furnishings, surfaces, lighting, acoustics, and climate comfort, as well as color, texture, and materials. In Norwegian usage, interiør is closely linked to interior design and decoration, sometimes distinguishing between architecture and the interior layer.

Key considerations include function, safety, accessibility, and ergonomics, ensuring spaces support everyday activities. Aesthetic decisions rely on principles such as balance, proportion, rhythm, and harmony, while material choices address durability, maintenance, and environmental impact. Lighting design, including natural daylight and artificial fixtures, influences mood and usability. Colour theory and textures influence perception and atmosphere. Acoustics and climate control affect comfort and productivity.

Common subfields include residential interiors, commercial interiors, and interior architecture, the latter at the intersection with building design. Professionals may work with space planning, furniture selection, textiles, fixtures, and decor. Tools include hand sketches and computer-aided design (CAD) models, mood boards, and material samples.

Historical influences vary by region, with Nordic design emphasizing simplicity, functionality, and natural materials, while international trends bring eclectic styles and sustainability. The term interiør also appears in retail and publishing to denote products and articles related to home decor and interior styling.
