Tebartz commissioned a bishop's residence complex named the St. Nicolas Diocese Center costing €31 million. Details of the project were kept secret from Limburg's construction authorities to quash rumours of stately luxuries such as saunas and wine cellars to interior decorations with precious gem stones. However, Limburg's citizens found the building to resemble a "Kaaba of Limburg", as the colour and its cubical shape resembled the Kaaba of Mecca. The diocese budgeted tightly. It often lacked the funding to afford basic overhead and upkeep of church facilities such as maintenance, and disbanded services such as daycare.
