Interior design is the profession of providing creative and technical solutions to the challenges of achieving a desirable purpose-built interior environment. The purpose of interior design can be broken down to: enhance the quality of life though functional design and ensure the design is aesthetically attractive to the occupant. The design process is in response to and in coordination with cultural and social codes and regulatory practicality requirements. For example an interior in Japan maybe designed very differently to an interior in Germany. However both environments will be based on very similiar requirements such as utilising space and health and saftey protocol.
Interior design has developed in recent years into a methodology which includes systems and cordination which utilises both creative and functional elements to ensure the relevant research and analysis is carried out and implemented with the overall purpose of completing a defined goal. This defined goal is often base on a client concept and budget which the most limiting factors to the final interior design outcome.
Another crucial factor which inhibits or controls interior design include 'interior architecture' which is based on the concept of the quality of design with a building a structure based on "architecture, structural systems design, heating and cooling systems, occupational and safety standards, interior design, specific end-use applications, and professional responsibilities and standards."
Home interior design is most notably based on a mixture of functionality and relaxation with environments for controlled living activity such as effective cooking, cleaning and personal hygiene alongside areas for family grouping and individual relaxation in sleeping areas. The need to ensure a home includes each necessary aspect can result in certain areas being less utilises than others. Traditionally corners of living room are often overlooked based on the necessity to supply cooking and sleeping facilities. To utilise the corner of the living room a demand has grown in recent years for well designed and smoothly proportioned corner units which contrast beautifully with other decorative and furniture styles whilst providing a functional solution which is almost always based on presenting the entertainment centre as beautifully as possible.
Recent years have also seen a number of recognised techniques based on minimalism which are designed to add space to the living room. These include using sheet mirrors, using minimalist hollow furniture, reducing the number of clutter and ornaments. However these techniques are often criticised for creating a bland, sterile environment which some home owners rebel against by introducing a large number of traditional elements such as large antique furniture and 'countryside' colours which generally including light brown shades which can make an interior appear darker and smaller than a bright white home environment. Lighting has also become an important element of interior design thanks to the development of small halogen light bulbs which can be used as small spot lights in both the floor and ceiling. Casting light across every area of the room, reducing shadows and creating a generally more interesting an warmer environment.
Interior design has also become more environmentally concious with a growing awareness of aspects such as organic paints, low energy lightbulbs, double glazing, solar panels, insulation and anti-allergy air suction devices. Colour has also developed into a incredibly important factor which is considered to be highly influential over the mood of people, such as red is considered to make people angry and fearful whilst blue can conciously and subconciously relax people, reminding them of the relaxing qualities of water. However dark blue can appear as a forboding colour which can appear as to dull and can aggrevate isolation and coldness.
