Doors in the stylistic plan may not depend on the interior. Sometimes they are even opposed to each other. A classic mahogany door with enamel decoration can lead to a room designed in high-tech style. Behind a strict glass door with an engraving, repeating someone's handwriting, can be hidden rococo boudoir. Designers come up with their collections in such a way that it is easy to install, say, doors on the whole floor with a similar decor. For example, all doors of various shades of precious metals, but patinated. Special attention deserve exclusive doors. With an embossed leather facade that is not afraid of moisture or temperature changes. Onyx, which seem to glow from the inside when sunlight falls on them. Covered with amalgam, like an ancient mirror.
