Alpha expands its business into green building consulting. International projects are carried out and partnerships are established.
The ALPHA companies merge into a single entity - lean, efficient and well-structured. Healthy growth and expansion of locations in Munich, Frankfurt, Vienna and Nuremberg characterize the company in subsequent years.
