A concept design for the reconstruction of an office building of class C. The main objective of the project is the redecoration of facades, without upgrading the structural component.

With the help of modern facade systems, the pitched roof was masked, the main and auxiliary entrances to the building were highlighted, places for placing elements of the existing navigation concept were provided.
