Internally the materials are chosen to contrast with the use of steel structures, which are painted a dark anthracite metallic gray, while walls surfaces are finished in walnut veneered panels, glass and white acoustic paneling. The use of stone surfaces continues in to the ground level public areas, in the form of a polished stone from Afyon, in large panels to give the sense of having been carved out of a large piece of stone. This element continues up the main stairs in the atrium.
