Yoyogi Park and Meiji Shrine are outstanding natural treasures just on the other side of Shibuya City Office when approaching from Shibuya Station. This essential context gave colour to the project by evoking images of the purity in the powerful yet peaceful green landscape and refinement in the serenity of Shibuya’s residential district. The exterior walls embody these words using panels with a tranquil green colour gradation which blend seamlessly with wall greening. The entire wall becomes a work of art aiming to harmonize the structural volumes of the city office with the soft urban shapes of Shibuya. This green colour gradation even flows into each interior with green walls lining the inside of the entrance hall. The sensational green design unifying both the interior and exterior abolishes structural barriers to make the Shibuya City Office as inviting as a park, which is ideal for public facility providing citizen services.
