About us
Since our foundation in 2018, we have built a passionate team of experts dedicated to bringing historic houses back to life while preserving their architectural soul and integrating modern comfort, energy performance and contemporary construction technologies.
At XTEND, our mission goes beyond simple renovation: we aim to create spaces that combine well-being, history and elegance. Whether for a private residence, a heritage building or a commercial project, each intervention is a unique opportunity to honour the past while preparing for the future.
We enjoy tackling complex challenges, finding creative solutions and continuously improving our methods to deliver the highest quality results for our clients.
We are specialists in solving typical technical and aesthetic challenges of older houses
Our approach is guided by close attention to detail: authentic material selection, respect for traditional construction techniques and harmony between old and new. Every decision is made to ensure aesthetics, durability and occupant well-being.

Michel Schaus, founder of XTEND, has transformed his passion for historic and contemporary architecture into a company dedicated to renovating and enhancing Luxembourg’s built heritage.
With over 20 years of experience in architecture and construction, Michel combines technical expertise, aesthetic sensibility and a sustainable vision in every project.
Before founding XTEND, he worked within large organisations, gaining comprehensive experience in managing complex projects, technical innovation and coordinating networks of craftsmen and partners.
This background enables him today to lead a team capable of handling projects ranging from the renovation of historic houses to the construction of traditional buildings and the restoration of listed heritage sites.
