10. Designer & Design Concept:
Za bor Architects.
 Arseniy Borisenko & Peter Zaytsev.

Design Concept:
The concept re-interprets common 2D pixilated items, and proportionately scales them into life-sized interactive art-objects. 
The architects had at least two challenges – first to organize a very complex space outstretched along a central corridor axis. The second challenge was to make the office a showy and impressive.

11. Special equipment & Furniture Inventory :
Visitors are welcomed at a desk resembling a text box and a giant arrow pointing towards a certain direction even the iconic Pacman is represented within the decor.
The most bizarre objects are used for zoning, conference halls and meeting spaces for informal communication and are scattered along the entire workspace
This unique office space, which is a 24/7 operation, is fully equipped for the comfort of its employees with recreational zones, a gym, cafeteria and lounge areas for the fortunate people who work in this excitingly different, colorful environment, In addition, a gym, cafeteria, showers, lecture halls and several coffee-points are seen throughout the inner scope of the development.
Familiar computer symbols are used for shelves, cupboards and separations and employees work amongst giant cursors, pixels and arrows throughout the various sections of the 200m long space.

21. Critical Opinion:
The design depends on lots of color that in my opinion will motivate the employees and provide the brain enough energy to make it active, Also the design concept reflect the company identity. Beside the space planning is elegant and have been used well.
