Adding a child's bedroom means deciding whether your want to add upward or outward. The addition of a new room for a child gives the option of adding features like built-in shelving for toys and books or adding an elevated bed to create more floor space. Among the things to consider when adding a child's bedroom are whether you want to have the child sleeping on the same floor as you and how easy it will be to transform the room after the child has left the nest.
A bathroom add-on can increase the value of your home as well as reduce the crowd waiting outside the door of your current bathroom. Designing your own bathroom gives you the opportunity to arrange the tub, shower and toilet yourself. An add-on bathroom can become a renovation job if you place it in your basement. If you add the bathroom aboveground, consider putting a window into your design to provide extra illumination. If you have the finances, your window can be decorative, as well.
A two-story add-on office can give you twice the space using less property than you would use with a one-room home office. Those who spend a great deal of time working at home might consider building an add-on that places your work area on the first floor and a mini-kitchen and half bath on the second floor. A writer could use the bottom floor for writing and the top floor as the library of her dreams. The two-story addition provides far more flexibility than a one-story addition.
A house plan that situates the dining room within the living room space or simply doesn't provide an adequate dining experience gives you the perfect excuse for an addition used primarily for eating. Your addition could attach to the house or be a completely separate entity. Make this home addition suit your dreams by designing it in the style of a French cafe, an Italian ristorante or an old-fashioned American diner.
