METTEN Stein+Design specialises in providing innovative products for a modern and contemporary design of residential environments.  This includes in-house developments, e.g. easy-to-clean paving stones and slabs that meet the highest standards in design and aesthetics.  A special highlight: the IVANKA QTZ urban elements launched at Miami Design Week 2017, designed by Alexander Lotersztain, Australian designer  and developed by IVANKA, the leading architectural and design company, as a concrete furniture for indoor and outdoor use.
