About us

TS CONCEPT - stairs & interior design for Luxemburg and the border region since 2008   

We are a trading and service company for high quality stairs, interior design, built-in cabinets and sliding doors. We work for private customers, developers and architects from the Grand Duchy of Luxembourg and the nearby border region around Trier, Eifel and Moselle.

Since 2008 we are there for our customers. We provide competent advice, develop individual and custom-made solutions and supervise all projects from the first meeting through to implementation. With great commitment and passion we pursue our highest goal: satisfied customers. 

Tino Schreier, cabinetmaker and graduate engineer for wood technology (FH), is founder and chief executive of TS CONCEPT. He has been an expert in stair construction for more than 20 years and is passionately dedicated to customer service and stair design. Every project is a matter close to his heart and satisfied customers are his greatest motivation. 

Catherine Lentz is an interior designer (B.A.) and has been enriching our company since February 2020 with her joy and creative ideas in the field of interior design. She plans and designs rooms with our high-quality and individual built-in cupboards, sliding doors and special designs. 

Melanie Schreier is an industrial clerk and marketing specialist. She is responsible for the administrative department and takes care of all matters concerning advertising and marketing. She is the contact person for all media and press representatives.  


The company was founded in 2008 by Dipl.-Ing. Tino Schreier together with Romain Hilger from the company OST Fenster under the name OST Concept. After the complete takeover by Tino Schreier in 2019, the company has been called TS CONCEPT Stairs & Interior Design Luxembourg since May 2020.
