Sisustust

Sisustust, or interior decoration, is the practice of shaping interior spaces to be functional, comfortable and aesthetically coherent. The term covers planning, selection and arrangement of elements such as furniture, textiles, colors, lighting and decorative objects in residential, commercial and public spaces.

The process typically starts with a brief, space assessment and budget setting, followed by concept development, space planning, material and color choices, procurement and installation. Professionals use tools such as floor plans, mood boards and sometimes 3D renderings to communicate ideas and coordinate with clients, architects and trades.

Core elements include space planning, color theory, materials and finishes, furniture, textiles, lighting and accessories. Sustainable and ergonomic considerations are increasingly integrated, with attention to durability, local sourcing and energy-efficient lighting and products.

Styles vary widely—from minimal and Scandinavian-inspired to contemporary, industrial or classic. In Nordic design, for example, emphasis is on simplicity, natural materials and light color palettes. Trends also include biophilic design, multifunctional furniture and the use of warm, tactile textures.

Education and practice: interior work is carried out by designers and decorators who may have training in interior design, architecture or related fields. In many countries, professional practice involves collaboration with architects, contractors and suppliers and awareness of building codes, accessibility standards and safety regulations. The term sisustust is commonly used in Finnish contexts to describe the broader field of interior decoration.
