Welcome to ULMA´s web site

This project entails the construction of a building along side the walls of the Puerta del Aceituno in Jaén. The building will have a main auditorium with the capacity to hold 630 spectators, various workshop rooms and two stories underground for parking (7,000 m²).The main auditorium is built on a hillside and all the enclosure walls are angled inward, which together with its great height makes a detailed study on all the lifts absolutely necessary.On the other hand, the inside closure must remain open for public access. Therefore, only the upper part is enclosed with an wide angled beam, which sustains the side walls. Given that the beam is not self-supporting until the structure is complete, all the beams and walls must be supported.

The work was instigated by the City of Donostia, in the Larratxo neighborhood. It is a construction project that used 600 m² of slab with thickness ranging between 30 and 35 cm. The Parking Garage has 2 underground level and three stories above the ground.

In this XIV Century castle, where one of the most important painting museums of Paris is found, it was necessary to completely protect it for the restoration, spanning a 15 m to protect it horizontally and vertically alike. Another characteristic to resolve was that the covering of one face had to be supported on the bottom of the lake, which wraps around the castle.

The purpose of the proposed intervention was to undertake the construction to restore the site, while simultaneously permitting programmed visits to continue inside the building.There was one phase in which the existing structure was reinforced with Brio material, and the façade was restored thereafter.
