What is a one-sentence summary of the following article?
Whether it’s a bedroom, bathroom, kitchen, or living area, each room has a function and a "target audience," those people who tend to use the room the most.  Your design choices need to reflect the target audience as much as possible in order for the room to remain functional. The rooms in your house should complement the personality of the person or people who use them most. For example, if your space will be used to host dinner guests or clients, you will want to take a different approach than if it is used as a nursery or playroom. Similarly, if you are the only one who will be using the room, you might feel more free to design it to your own standards and not worry about how others will see it. Ask someone for help to make sure your measurements are accurate, and write them down as you go. Measure each wall's length and height, as well as any permanent fixtures to the room (like built-in cabinets, fireplace, bathtub, etc). Don't forget to measure windows and doorways, including width and height. Before you can plan your design, you need to know what you have to work with. If you have an unlimited budget, then you can skip this step! Otherwise, think about each part of the room's design, which you are interested in changing, and how much you can afford to spend. This will help you focus your design on those elements you can afford to update. For example, you may not be able to put in a new carpet, but you might be able to buy a throw rug to cover up the carpet and update the look. Your budget should be a list that includes general categories and a specific breakdown of how the money will be spent in each category. It will be unique to the room that you are designing, so it will differ depending on if it is a kitchen, living room, bathroom, bedroom, etc. Some aspects to include in your budget might include:  Walls: Do you need to paint? What about repairing, replacing, or adding features like wood trim, crown mouldings, or paneling? How about wallpaper? Windows: Do you need new windows altogether, or can you keep the ones you have? Old windows can be drafty and dated, and hard to clean. But they can be disguised with good window treatments. Do you need new blinds? What about draperies, curtains, valances, or other window treatments? Flooring: Do you need to replace the carpeting? Do you want to put down hardwood floors or tiling? Could you just get by with steam cleaning the existing floors and perhaps adding an accept rug or area rug to update the space? Fixtures: Does the area have light fixtures or chandeliers that need to be replaced or updated? What about outlet and light switch covers? Does it have a sink, faucet, or bathtub that needs updating? What about countertops, cabinets, or appliances? Furniture (couch, chair, table, bookshelf, bed, etc). Décor: This includes everything from the pictures on the wall to the throw blanket on the couch. In many cases, you can renovate the appearance of a room by just changing the décor items. Do you want to add photos or canvases to the wall or to shelves? What about figurines, wall hangings, or soft lines like throw pillows or blankets? Think practically first: What furniture do you need in order to use the space? Items like a bed, dresser, or couch might fit this description. Then, consider what furniture items would make the space more user-friendly or fun, like a coffee table, bean bag chair, or accent table. As you write down the furniture, make a note of what you currently have and what you might need to buy. Using themes and designer tips from professional decorators will help get the creative ideas going.  Experiment with different furniture arrangement options using free room planning websites. Search online for "interactive room design" to get started. You can also use these websites design a virtual room from flooring and paint colors to cabinets and counter tops. Know which cleaning supplies, painting supplies and any tools or equipment are necessary. Have someone ready to help you move any heavy or fragile furniture.
