In this article specific examples of historical interiors are identified and characterized, environment-forming factors determining the individuality of the historic interior and its renovation strategy are highlighted; shows the methods of renovation andreprofiling of historical interiors, their selection and testing in real environmental conditions.The historical buildings that make up the golden fund for the development of old cities often carry a bunch of contradictions: their interiors do not alwaysmeet today's requirements for the geometry of interior spaces, their hygiene, lighting, acoustics; the structural basis does not allow to increase the load; they are not designed for new functions, modes of operation, flows of people, etc.; the existing aesthetic system contradicts modern materials and stylistic priorities. Incorrect adaptation of historical interiors to a foreign function leads to irreplaceable cultural and artistic losses. Therefore, it is relevant to identify techniques for the renovation of historical interiors, architectural and design tools to ensure consistent interaction of the historical foundation and modern equipment.The study allowed to clarify the concept of “interior of a historic building”; to reveal the factors that determine the design approaches to the renovation of the interior: initial geometry, hue-color certainty and potential, artistic and stylistic integrity, scenographic potential, sanitary-hygienic and ergonomic, safety, human factor, compositional reality and potential. The identified factors made it possible to formulate the tasks and means of renovating aspecific historical interior. The methods of renovation are: the introduction of a contrasting accent; creation of alternative environmental and stylistic scenarios, points and perspectives of perception; use of environmentalinstallations from equipment; the formation of a single visual field of the interior and exterior through the use of font, elements of historical style.The article “Architectural and design techniques for renovating the interiors of historical buildings” clarifies the concept of “interior of a historical building”. The features of such interiors were identified and characterized, environment-forming factors determining the individuality of the historical interior and the strategy for its renovation, as well as design approaches to interior renovation: initial geometry, light-color certainty and potential, artistic and stylistic integrity, scenographic potential, sanitary-hygienic and ergonomic, were identified, security, human factor, compositional givenness and potential. The methods of renovation and reprofiling of historical interiors are shown, they are selected and tested in real environmental conditions. The identified factors made it possible to formulate the tasks and means of renovating aspecific historical interior. The methods of renovation are: the introduction of a contrasting accent; creation of alternative environmental and stylistic scenarios, points and perspectives of perception; use of environmental installations from equipment; the formation of a single visual field of the interior and exterior through the use of font, elements of historical style. The article is illustrated with graphic materials from the course student work (Art. Yulia Shtyrbu).
