Clear geometric shapes, fast precise lines and color are present in every detail of the interior. The main advantage of INT-MEC was a magnificent view of Lviv. We gave up many rooms and cells in favor of open space. There are no clear boundaries in the planning, the spaces flow with each other, separated only by formal visual partitions. The filling of the interior is restrained, the number of items is minimized, although many facades hide large storage spaces. The complex engineering component is successfully hidden. The complex of these solutions creates the lightness of the interior, but does not take away such important comfort and necessary storage systems. We are proud that almost all complex elements were made by local manufacturers according to our sketches.
