Your local architect
Let's work together! Whether it is a case study, preparing building permit or execution planning, you benefit from the long-time personal experience in creating value in one of the most unique areas in Switzerland.
Project development
Architecture is like jazz. Jam sessions over and over again, playing together with strangers. One thing is common: we speak the same language. Let LARX do the work for you while you free up resources for other tasks.
Visualizing your ideas
3D models and renderings are not the goal but an instrument to help understand each other in all the design phases. Use it as a planning tool or to help communicating your ideas. LARX creates detailed virtual models, as well as sketch-like to realistic images.


LARX is a young company founded by László whose life has been committed to architecture for more than 20 years.

He has always been passionate about architecture and found pleasure in logical thinking, the process of creation, the beauty of structures, as well as effectively using the latest digital technologies. He is a visionary thinker who greatly contributed to several large-scale, international projects from residental developments to cultural art facilities.

He was born in Hungary. Prior to 2011 he had been studying and working in Budapest and also attended the San Diego State University in California. He obtained a Master of Sciences Degree at the Budapest University of Technology and Economics, where he completed a rigorous honors program in public building design. Being involved in various projects in China, his international journey in architecture began.

In 2011 he moved to Switzerland, and after finding employment in St. Moritz he quickly became a project architect. As a trusted and goal-driven employee he managed and successfully delivered complex projects. He also had the opportunity to work together with renowned international firms like Foster+Partners, Christian Liaigre or Jacques Garcia.
