LOT-EK is an architectural design studio based in New York City and Naples, Italy. Founded in 1993 by Ada Tolla and Giuseppe Lignano, the firm is particularly well known for their critical and practical research into the adaptive reuse (“upcycling”) of infrastructural and industrial objects — most notably the standard 40-foot shipping container, which they have applied to the design of institutional, commercial and residential projects globally.  In addition, LOT-EK has conceived and executed exhibition design and site-specific installations for cultural institutions and museums, including the Whitney Museum of American Art, MoMA, the Walker Art Center and the Guggenheim, among others. 
Ada Tolla and Giuseppe Lignano each have a Masters Degree in Architecture and Urban Design from the University of Naples Federico II, Italy (1989), and have completed post-graduate studies at Columbia University, New York (1990-1991). In addition to heading LOT-EK, they currently teach at Columbia University, Graduate School of Architecture, Planning and Preservation in New York. They also lecture at universities and cultural institutions in the US and abroad, and have presented at conferences and meetings about sustainability and the built environment, including the Holcim Foundation for Sustainable Construction (Mexico City), and the Kyoto Institute of Technology (Kyoto, Japan), among others.
In December 2011, Ada and Giuseppe were recognized as USA Booth Fellows of Architecture & Design by United States Artists.
UPCYCLING & SUSTAINABLE ARCHITECTURE
LOT-EK’s ongoing research has focused on man-made objects and systems and the way they proliferate, accumulate, overlap and interfere with the built, and natural, environment around the globe. They are internationally recognized for initiating the concept of creating architecture with shipping containers and has leveraged this construction technology with projects at all scales.     
In addition to utilizing containers as building blocks for architecture, LOT-EK has upcycled other objects – including truck bodies, airplane fuselages, and reclaimed wood or steel doors – as structural interventions to design buildings and interiors.   
LOT-EK has collaborated on several international master plan projects, working with colleagues such as Kengo Kuma (Beijing, China), MVRDV (Almere, Netherlands) and the BOOM Residential Community project in Palm Springs, CA, with Diller Scofidio + Renfro, Jürgen Mayer H., Joel Sanders, SurfaceDesign and HWKN.
