We actively help shape the construction of tomorrow in a positive way and think beyond standards.

We are LXSY. Based in Berlin, we are involved in the field of circular planning and building and are actively committed to the transformation towards a climate-friendly construction industry that conserves resources and avoids waste. As ambassadors of the building revolution, we set new standards for the future of architecture and question established processes in the construction industry. We transform existing buildings and are pioneers of circular construction.

Beyond making architecture, we aim to spark a positive social, cultural and ecological impact. As architects, we are concerned with the question of how we as a society want to live and work together in the future. We think conserving resources while adopting circular planning and building techniques will play a key role in steering towards a more sustainable future.

PROJECTS

Living

DOROTHEE-SÖLLE-HOUSE

Project Phases 1–2 • The conversion transforms a listed brick building and a former office building in Hamburg-Altona into a resource-efficient residential ensemble with student housing, coworking spaces, and active ground-floor uses. By largely preserving the existing structure, 222 student places and shared facilities are created with strong connections to the surrounding neighborhood.

Education

REUSEBOX

Competition • The ReUseBox Heilbronn is a learning and demonstration center that makes circular economy tangible through architecture, material use, and spatial experience. It demonstrates how reuse, resource awareness, and sustainable construction can be applied in practice.

Work

FUNKYTOWN

Project Phases 1–2 • Trockland is developing the urban creative district FUNKYTOWN on the former GDR broadcasting site on Rummelsburger Landstraße, featuring eight new buildings and the historic Block-E. Station E by LXSY combines circular construction with urban aesthetics through a wavy metal façade and reused brick.

Living

GDR STANDARD HOUSE

Competition • The project, in collaboration with asp architects, demonstrates how a GDR prefabricated house in Erfurt can be sustainably transformed through circular construction and the reuse of materials. From the serially produced stock, a vibrant, resource-efficient, and social space emerges, fostering both community and environmental well-being.

Neighborhood Development

TEMPELHOFER FELD

Competition 2nd Phase • „A Sea for Everyone“ preserves Tempelhofer Feld as Berlin’s green lung, enhances biodiversity and climate resilience, and links sustainable urban development with freedom, history, and social cohesion.

Work

SCHWANENWALL 11

Competition 2nd Prize • Transformation of an urban building block: Schwanenwall 11 in Dortmund is becoming a showcase project for future-orientated construction. The transformation combines resource conservation, social and ecological sustainability and timeless design. The building is being revitalised with new uses, a reused façade and innovative concepts.

Education

JEWISH CENTER FRAENKELUFER

Competition • The Jewish Center Fraenkelufer creates an open, secure space for community and encounter. Cubic building volumes, terraced outdoor areas, and flexible interior spaces merge tradition with contemporary Jewish culture. Sustainable materials and greenery make it a vibrant, identity-forming ensemble.

Circular planning and building is not a nice-to-have.

For us, architecture is an attempt to find answers to the most pressing social, societal, economic, and ecological challenges of our time within the built environment.

As architects, we set new standards for the future of architecture and challenge established processes in the construction industry. We transform existing structures and are pioneers in circular construction. Achieving a shift in the construction sector requires a transition to a comprehensive circular economy. In doing so, we combine ecological and social sustainability.
