In this case, the client decided to install a harp-style balustrade on the wooden stairs leading to the attic. The white stairs with darker elements of the black balustrade create a unique color contrast in the room. An additional element that complements the aesthetics of the stairs is the interesting ambient lighting that shines from below the stairs through the gaps between the steps. This effect adds depth to the interior and creates a pleasant, light atmosphere. This project perfectly demonstrates that a harp-style balustrade can not only secure the stairs but also serve a decorative role, adding elegance and character to the room. The combination of wood with the metal balustrade and subtle lighting creates a space that captivates with both functionality and aesthetics.
