Small scale changes in an existing office. Keep the old floor, just place on top of it fine laminate and you may change the atmosphere. New aluminum doors, efficient lighting, colorful walls, style of painting, soft wallpapers, cabinets with doors that depict projects that belong to the past, model and mosaic display are some of the simple ideas that turned an old typical engineer office to a modern and functional place in only 21 days without disrupting its operation.
