Interior stairs and indoor staircases - for all senses

Interior staircases are able to enhance the living room and become more than just „a staircase“. Depending on the choice of materials, the layout of the staircase and the location the interior stair can let light into the room, radiate warmth or just look great. Siller designs and manufactures stairs in wood, glass and concrete, acrylic or steel according to your wishes.
