Modern architects and interior designers are mostly used to large, bright space in which it is easy to demonstrate their design skills. However, it is still not enough products and services for large group of interior users, mainly flats users, with a small size of the area. Most of them are not completely satisfied with their rooms. Usually, spaces seem to be too small, too tight, or simply they have the wrong proportions. There are a many design problems in these small interiors, and they constitute the greatest challenge for designers.

In addition to the selection of equipment during the formation of a newly designed interiors, and repaired, or adapted rooms, designer should consider several important factors that affect the optical change in the size and proportions of rooms. It’s possible to correct interior without redesigning or destructions with the help of optical illusions that changed the visual perception of interior space. A room can be visually enlarged, heightened, deepened, broadened, narrowed, or lowered. Things like color, lighting, materials, pattern, texture, forms, shapes, placement interior elements, horizontal or vertical lines, mirrors and even styles of interior equipment and finishing materials can correct the interior space because they can have a significant impact on the size and proportion of a space.

Color selection of both walls, floors, items of equipments and accessories is one 94way to change the visual size and proportions of the rooms. Using the visual effect of colors and appropriately selecting and comparing cold and warm, light and dark, complementary and contrasting colors, designer can easily manipulate the length, width and height of painted interiors.

Another factor, lighting, a decisive influence on the final image of the rooms. Suitably manipulating the color, intensity, location of light and number, type and size of points of light, we can improve the appearance of the interior optically.

Trying to “trick the eye” of the observer we should pay attention to the nature, diversity and the appropriate combination of finishing materials and materials of equipment. The effect can be a result of the material texture, pattern, color, gloss, etc.. Similarly, we can use to put the interior decorative designs and patterns. One more thing that also contributes to the change and correction of the interior space is the style of applied finishing materials and interior articles.

Spectacular changes with little effort can be achieved by the applied mirrors. Thanks reflections and optical illusions they provide an opportunity to significant visual enlarging of room space.

But the basic principle helpful in organizing small spaces is to care for the maintenance of order, not just architectural. Glut of different shapes and forms of elements, excessive amount of additives and the introduction of different levels on the walls and among the items of equipment may disturb the order and spoil even the best planned actions directed toward the arrangement of optical improve the appearance of the interior.
