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.

Sylvie Grabowski is an interior designer (B.A.) and inspires us and our customers since January 2023 with a lot of enthusiasm and creativity around individual interior design. She advises, plans and designs rooms with our high-quality and custom-made built-in wardrobes, sliding doors and special designs. 

Melanie Schreier is a trained industrial clerk, marketing specialist and PR consultant and is responsible for the administrative area. She takes care of all matters relating to advertising and marketing and is the contact person for media and press representatives. She is involved with heart and soul since the very beginning and ensures a smooth flow in the office and showroom since 2011. 

Catherine Lentz is an interior designer (B.A.) and has been responsible for Interior Design since February 2020. Thanks to her calm nature, she keeps a cool head even in turbulent situations and has already implemented many beautiful interior design projects with her creative ideas.

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.
