In the present demand-driven market, hen time plays a key role, the adopting of a flexible strategy easy to implement may be the answer to create an architecture that meets all requeriments. The adaptation with membranes in a rehabilitation, in this case, is an economic ay in which this complex as rethought for the ne requeriments. The membrane contributes towards the stability of the structure, that is compose out of frames, that bear the load of the membrane material, fixed between the buildings, thus creating new spaces and new possibilities. By introducing this new element ith its properties, we do not only reshape the complex in a functional way, but we also make it sustainable in connection ith the past and the present, creating a new way for the future, in this demanding ever changing market. Therefore the textile structure that covers the access area from the "Magical" Llleida Technological Park is driving this process forward ith its persistent commitment to researching and developing ne practical design concepts, functions and construction solutions methods. This new approach has a better environmental behavior based on its efficient use of resources, and its easy maintenance and renewal, thus moving it ahead from other standard solutions, making it a so-called pioneer of its generation. The aim of this paper is: a) to sho that there are other methods apart from the traditional ones, for a construction and in some cases more suitable; b) to describe the main characteristics of the "Magical" Lleida Technological Park, with emphasis on the closing textile structure; c) to explain the closings capacity of sustaining itself by responding to the environmental conditions.
