Usually those who want a modern style refuse wallpaper. They think it's something old-fashioned. Naturally, this is a prejudice.
There are now a huge number of options in stores and salons: imitation of skins, metal, plaster.
Wallpaper is a type of coverage, it is a form. And the essence can be any or almost any. Show the client this to expand their boundaries.
Some clients, on the contrary, are afraid of plaster and prefer only wallpaper.
At the word "plaster" they think about plaster in a budget house. You can scratch your hands on it and it is completely unacceptable in an apartment.
However, plaster displaces other coatings because it is practical. And in the design there are cool options: imitation of the skin, leather, stone and wood.
And once wood-effect plaster saved us. We made an office 5 meters high. From above, they thought to make wooden beams to hide the ventilation. But wood is an expensive and heavy material.
And we used decorative wood-like plaster. At such a height, it is not distinguishable, but much cheaper, lighter and more practical.
