Open space often appears as an architectural and spatial concept of linking the living room, dining room, kitchen and other facilities in a harmonious whole. It represents a response to pressures, which appear daily and his visual component emphasizes a sense of freedom. Space connecting can be achieved through horizontal or vertical floor linking.Whole space, divided by functional group placement, is experiencing larger and lighter and much more comfortable than smaller and separate entities. Open space release and opens borders and as such it is the perfect response to modern life that encloses and separates us, mostly due to lack of free time. To ensure this open space fills all of its roles, it is especially important to match its functional and aesthetic components.Functional component is primarily related to the proper arrangement of elements within a single group – the living room, kitchen, dining room, working space and the proper relationship between the groups themselves. Staying and performing some activity in one functional component should not interfere with activities in other components. Communication flows between them should be clear and logical in order not to upset the entire function circuit. By example this means that the open space should be organized in a way that while a dining room is located in the middle, the kitchen and the living room are placed left and right of it. Such spatial relationship enables seamless communication between groups – kitchen and dining room where usually all activities of preparing and serving food are performed, while the activities in the living room are completely independent event.In case the living room as a group should be extended because of the increased number of household members and guests, the dining room ideally can be used for additional accommodation and increase the number of seats. Their good mutual disposition will allow excellent visual contact, communication and the possibility of joint watching of TV programs.Functionality without aesthetics is nowadays not acceptable any more. Open spaces, regardless of the functional division, should be unique in providing atmosphere. Random colors, materials, fabrics and styles should be adjusted, as they will in that way emphasize the dimensional quality of open space. It is advisable to combine up to four different materials or colors in a way that the two colors or materials are dominant, and the other two appear in the details and decorative elements. Too many colors and material types in open spaces will reduce the visual experience, and that certainly is not the goal of open space philosophy.Experimenting with styles is also allowed, but with careful selection of elements and details complementing each other. The safest choice is to choose any style you like, but complemented with details such as chandeliers, lamps and pictures in another, different style. If you want to follow trends, select the minimalist geometric elements and add few retro details and emphasize them.Open space concept provides lots of opportunities in the creative expression and the creation of effective spatial experience. It will certainly contribute to large amount of daylight and lighting solutions. Central and individually placed lamps with the possibility of regulating the strength of the light shall create a special experience in the area, which can be individually adjusted depending on the wishes and needs.Selection of open space as a spatial concept of the future house or apartment is ideal because it offers the possibility of fulfilling all desires, highlighting the personality of the space and creating an environment that will satisfy all functional and aesthetic criteria.
