Services of interior architects

Interior architects create purposeful and pleasing environments for the needs of clients and users within the limits of financial realities and with respect to environmentally ethical values. Interior architects integrate structures, furniture and furnishings, light, colours and materials into functional entities, and they create spatial atmospheres with lighting and by other concrete means. Interior architects cooperate with clients, users, architects, contractors and engineers (structural, mechanical, electrical and plumbing) as well as with furniture, furnishings and materials suppliers.

Interior architects design interior renovations and alterations both in public-sector and private-sector projects. Their tasks include spatial, surface, interior and lighting design; furniture and exhibition design; and branding and corporate identity design. Interior architects develop and strengthen their corporate clients’ visual identity and brand, and they conduct comprehensive conceptual design. The key tasks of interior architects include the design of especially fixed furnishings as part of overall interior design. Some interior architects specialize in the design of mass-produced furniture, lighting fixtures and other interior design components for industry. Interior architects provide diverse solutions and services for both private individuals and businesses.
