WIX.COM Office 4 in Vilnius was designed as an expansion of the previously implemented Office 2. The key feature of Office 4 is a large meeting space set up in the middle of the premises. Besides fulfilling its direct function, it reflects WIX.COM's cooperation and openness policy. The round glass volume nicknamed ‘the Coliseum’ hosts all sorts of lectures, workshops and events for young professionals often organised by WIX.COM. The premises around the central volume are intended for workgroups and meetings. The characteristic ceiling unites rooms of different functions into a coherent whole. The purpose of the ceiling is not only acoustics; it is also a huge reflector emanating scattered light pleasant for the eye. The white and light interior accentuates natural materials and colourful inclusions. Each work space has special walls meant for work and leisure communication between employees as well as for display of their personal achievements.
