Tinell Hall The need to introduce air conditioning and security installations in the "Tinell Hall” to adapt it to exhibition uses, together with the impossibility of working on the walls and ceilings of the hall for conservation reasons, lead to (taking advantage of the unevenness of the ground and the fact that this stone floor is recent) introduce a horizontal platform that accommodates between its surface and the existing ground the ducts and the facilities necessary to guarantee its use as a space for exhibitions. Frederic Marès Museum The renovation and conditioning works on the ground floor of the Frederic Marès Museum had as their basic objectives the facilitation of direct access from Dels Comptes Street (up to this point public access was only possible from the Verger courtyard, a half-private space), create reception spaces and temporary exhibitions, generate visuals from the street towards the interior of the museum, and update accessibility and facilities to comply with the corresponding regulations. Padellàs House During the consolidation operations of the Gothic Quarter of Barcelona, the Plaça del Rei finished its building process with a Gothic building moved from its original location in Mercaders Street to its current location. The works were carried out in the years 1931-1932 and during the transfer the façades and the courtyard were basically preserved but the interior distribution was carried out in accordance with the functional needs of the moment, even the transfer of façades and patio so the stone walls, originally structural were transposed with others (that would form the real structure) of brick factory. Therefore, we could think of actions to reform the building to adapt it to the new exhibition uses and the current regulations against fires and accessibility, of a certain force. But, on the one hand, the wall structure of the building itself, which is difficult to manipulate, and especially the central position of Padellàs House in the Gothic Quarter of Barcelona, discouraged any modification, no matter how small, of the image of the house. So, even the initial plan to close the windows and balconies with shutters (which would have returned the house to its civil origin) was rejected during the work to avoid any modification of its current external image. Due to these limitations, the interior of the building has been worked on, initially consisting of watertight structures grouped on the ground floor and two floors, flashing structural walls and establishing double spaces with the intention that the whole building can be understood, in its journey, as an exhibition unit.
