VITRUV'S LEGACY
Three principles.
One attitude.
VITRUV'S LEGACY
Durable.
Functional.
Beautiful.
firmitas – durability
utilitas – functionality
venustas – beauty
Vitruv defined the basic principles of good architecture back in ancient times. His three principles still shape architectural thinking today.
#VITRUVapproved – #VITRUVapproved
DURABILITY
Stability is the foundation of all good architecture and every well-designed product solution. ‘Firmitas’ stands for robustness, quality, durability and thus also sustainability. Materials, construction and technology must be reliable and retain their function for years to come.
FUNCTION
Architecture, products and interiors should not only be aesthetically pleasing, but also practical, user-friendly and functional. Every detail has a purpose, every solution makes everyday life easier and ensures intuitive and efficient use.
BEAUTY
Venustas stands for aesthetic harmony, proportion and timeless elegance. It evokes emotions, attracts attention and brings rooms or products to life. A stylish design remains in the memory and conveys value.
Inspired by Vitruv, designed for today.
Gira
KEUCO
TRILUX
Whether intelligent building technology, perfectly designed bathroom solutions or innovative lighting concepts – every product from the three brands combines the highest quality, well thought-out functionality and aesthetic excellence.
