Whether saving space or expressing it in another way, economic use of volumes takes place among the most important architectural and design issues of our time. The growing population of places in South Asian countries and especially in the developing cities of major economies, where the world population is concentrated at a very high pace in cities and especially in urban centers, especially where almost all the production of land is concentrated, makes the issue of saving more seriously. Because of this situation, average house sizes are decreasing, multi-storey building becomes routine, and sometimes even these are inadequate to provide housing for the dense population. These topics, which occupy areas such as urban planning, urbanism and architecture, obviously cause certain reflections in interior design and decoration and in the design and production of various household items. For example, houses that can be considered very small in the past and certainly considered inadequate can become standard. Maybe twenty or thirty years ago, a room that can only be considered a children’s room or a guest room can today be the most central area of a house, living room or hall. Shrinking volumes also require more practical, more economical, more functional furniture. This is exactly what we want to address in this article. In this comprehensive collection we have prepared for you, there are various furnishings and designs that are often used in carefully designed houses by professional interior architects , which will save space for your different rooms and provide you with an efficient use of your space.
