Relocating the office to the BuchHaus in Cologne S + P realized the vision of an own lean office. The concept focusses on the human being and the communication culture. This strengthens the exchange and the cooperation between the employees and enables a creative and flexible mode of operation. In flexible and variable rooms motivating workplaces came into existence where team-oriented working processes – and not the hierarchy – shape the room situation. During the implementation a lot of parameters to increase wellness and thus performance of employees were taken into account: good indoor climate, optimal light conditions, ergonomic office furniture, high quality equipment, low noise level by acoustic measures and short distances.
