Klaud works across architecture, urban design, exhibition design and art production.

We love cities and the culture that results from living together. We are led by the desire to improve the way we live together and committed to making our surroundings a better, more inclusive and enjoyable environment for everyone. This is also reflected in our approach to making those changes happen in the most sustainable way possible. We have developed a sense for sustainability which fosters careful consideration of people, processes, materials, and a culture of ‘looking-after’ which starts when a project is completed.

Together with our team and our clients Klaud has built up extensive knowledge in designing and managing large & small scale architecture and urban design projects. One area of focus is art-centric projects, which include exhibition architecture, museum & gallery design, art installations & production and working in close collaboration with artists and curators. Another key focus are public space projects, which includes developing cultural and public realm strategies and their implementation. The studio's expertise also reaches historic building renovations as well as residential construction and refurbishments.

Klaud - Koepf Lechthaler Architecture and Urban Design - was founded by Sebastian Koepf and Andreas Lechthaler and formerly known as Andreas Lechthaler Architecture (ALA).

Andreas Lechthaler
Andreas has extensive expertise across architecture and urban design, specialising in the contemporary art context where he collaborates with national and international cultural institutions, artists and curators. Andreas has led large-scale refurbishments in historic landmark buildings in London and Los Angeles for gallery Sprüth Magers. He has created the architecture of key solo and group shows at international institutions and festivals, including Tai Kwun (Hong Kong), Hayward Gallery (London), Wellcome Collection (London), the Biennale of Sydney, and Gropius Bau (Berlin). Regularly working with Swiss artist Pipilotti Rist in giving her vision an architectural expression is part of Andreas’ passion. He has a keen interest in creating holistic environments and spaces, where the existing and the new strengthens the experience of a place and creates a setting for human interaction.

Andreas is a UK qualified architect and has studied architecture in Florence (IT) and Munich (DE). He set up Andreas Lechthaler Architecture (ALA) in 2009.

Sebastian Koepf
Sebastian has comprehensive knowledge in leading public space and architecture projects for private and public clients. Sebastian worked with landscape architect Martha Schwartz before joining Burns+Nice in 2005. As an associate he led and worked on large scale public projects for Transport for London, including the Mayor’s Cycle Superhighways, the urban integration of several Elizabeth Line stations as well as the redesign of Leicester Square City Quarter. He also worked on a number of public space projects throughout the City of London and Westminster, States of Jersey and Guildford Borough Council. 
After joining ALA in 2017 he co-led with Andreas the design and implementation of large scale contemporary art exhibitions and public commissions, gallery refurbishment and museum strategies, private residential developments and most recently the Soho Photography Quarter public space and cultural strategy. Sebastian has a keen interest in nature and the urban landscape, loves how both evolve and never stand still. 

Sebastian is a UK qualified architect and studied architecture at the Technical University Munich (DE).
