Kitchen aisle - ST-ONE

ST-ONE kitchen aisles are a development of Strasser Steine GmbH, the leading stonemason specialist from Austria. Strasser stands for high-quality and exclusive materials in kitchen countertops and is the pioneer of natural stone kitchens. The permanent focus on innovation and quality as well as the customer centric thinking makes Strasser the perfect partner for K2 home design to plan and create top of the line natural stone kitchens.

To fulfil all your wishes within your project we work together with high-quality labels like next125, BORA, Quooker, Gaggenau, Siemens studioLine, Blanco or Liebherr.

After more than 25 years of designing and planing high-quality kitchens in Germany, Austria and Switzerland we wanted to expand our offerings and services to the Mediterranean area, to fulfil the need for modern and individually planed kitchens. Our clients wish to match their seaside villa with an according, luxurious interior. To be in reach for our customers in this area we opened our flagship store in the summer of 2020 in Port d´Andratx, Mallorca. The ideal product for highest-quality expectations is our kitchen aisle ST-ONE created out of natural stone from different mining areas, in combination with other natural materials like leather or wood and innovative functionalities like in-drawer lightning.
Every kitchen island is unique – as unique as our clients.
I’m looking forward to your visit.
