Sometimes painted walls are just not enough and it feels that space is missing some depth and warmth. Wall wooden cladding is a great feature to break down space into various areas or just to highlight a specific part. Wood helps to soften modern and industrial style interiors and makes them look more inviting. 

Wooden panelling could be used as a door feature.

Or if you have high ceilings and would like to balance it out wooden cladding will visually bring the ceiling a bit lower.

Otherwise integrating it into the joinery or just using as a wall decoration will always make it a bit more special.
