Even today, in 2017, the Sagrada Familia is still unfinished. Some people think it would be best to leave it as it is, as continuing may mean not fulfilling the wishes of its creator (Antoni Gaudí). But the work continues, under the direction of Jordi Faulí.

The question that this raises is: how do you continue with a building if its architect has died? Well, the most effective way of visualising a building is to create a model. So, right from the start, Gaudí had 1:10 and 1:25 scale plaster cast models made of many parts of the building. Although some were lost, the architects Francesc Quintana, Isidre Puig Boada and Lluís Bonet Garí managed to restore them.

Based on these architectural models, the latest 3D technology has been used, allowing the geometric patterns on the plans originally drawn up by Gaudí to be recognised, thus facilitating the procedure. It is expected to be completed by 2026, to coincide with the 100th anniversary of the death of Gaudí.
