At Work Construction Profile Lideta Mercato



Vilalta Studio operates in the fields of architecture, urbanism and design.

Declaring that “we love nature and we care about people”, our design philosophy is to connect the old and the new, co-opting and updating the best thinking of past traditions to create modern buildings that are both deeply respectful of the past and searingly contemporary.

Our work combines innovative technology with local resources and culture to create contemporary designs suitable for their environment.

A variety of institutions worldwide have recognised our innovation in the architectural field. Among these awards there are the Young Architect of the Year at the LEAF Awards 2008, in 2009 and 2010, the SAIE Selection at Energy Exhibition in Bologna, Italy. In 2013, we received an international cooperation award from the Association of Architects of Catalonia and an Honorable Mention for the Modern Atlanta Prize. In 2017 the Lideta Mercato was honoured by the UNESCO Prix Versailles as the best shopping mall worldwide.

Xavier Vilalta is the founder and director of the studio. He is a distinguished international architect specialised in sustainability. He is a former associate professor at the Barcelona Tech-UPC School of Architecture, where he taught design courses and mentored diploma projects.

He is a regular keynote speaker at events and conferences. Among others he has delivered talks at TED Global, Commercial Real Estate Week and Brunei World Architecture Day.

In each project, we create a comprehensive development proposal to ensure a final high caliber delivery representative of the future in relation to design, engineering and project management. This outcome is achievable through the creation of a richly integrated project, which will be delivered by capitalizing on the combined knowledge and experience of a team of hand picked experts appointed to create the proposal and manage the process from start to finish.

We work with our clients and the community to optimize the potential of the site understanding the unique challenges and opportunities of the project. Our holistic approach includes the city scale, patterns of behaviour, demographics and the hidden systems that can influence the built and unbuilt environment.

Interior Design

We believe architecture should provide a seamless experience from the outside to the inside, becoming essential the quality of light, the choice of materials and the use of color, as a coordinated part of the overall scheme. Each of these elements involves the same process of questioning and refinement as the building itself.
