Make a mirror wall Any mirror visually expands the space and increases the amount of light in the room. For the entrance area, both effects are important, as it is usually a small dark room with no natural light. In the case of an elongated hallway, you can work on a visual change of shape by attaching a mirrored canvas to one of the walls. So the space will almost double visually, and the proportions will seem more correct.
Choose a light palette A universal solution for any small space is light shades in the decoration and furniture, which visually expand the space. In the case of a narrow hallway, thanks to a light palette, not quite harmonious proportions are so striking. If you choose furniture in the tone of the walls, then even in a small entrance area you can fit a full-fledged wardrobe.
Paint the walls in a non-usual way An interesting and unbeaten solution for non-standard rooms is complex painting. The combination of different colors and shapes distracts attention from the wrong proportions, and this technique is great for the entrance area. For example, you can use a color block and take a few rich contrasting shades.
Put a bright door The front door does not have to be in the shade of “light oak” or “wenge”, you can put a model of a completely unusual color. It will act as a bright accent and solve two problems at once: it will revive the space a little and attract attention to itself, distracting it from the irregular elongated shape of the room.
Use glossy surfaces Another win-win solution for a small space of an uncomfortable shape is glossy finishes or furniture. Such surfaces, like a mirror, reflect and increase the amount of light, and also work on the visual expansion of space. In a small elongated hallway, you can use glossy flooring or make such facades of furniture: for example, a wardrobe or a chest of drawers.
Make an accent wall A simple way to distract attention from the shape of the room and at the same time add brightness to it is to decorate an accent wall. You can use any saturated color: for example, yellow. This shade will make the interior sunnier, which for a dark hallway will be very useful. You can support the color spot with a floor covering similar in tone or furniture fittings.
