Playhouse

• Add a porch to the front of your playhouse for rain-free fun.Hemera Technologies/AbleStock.com/Getty Images
  
  A metal building with windows makes a great playhouse for kids. For little girls, add window boxes and fill with blooming annuals outside of a lace-curtained window. A small set of table and chairs and a miniature kitchen set should be joined by a shelf of books and a basket full of doll and stuffed animals. For boys, paint your building fire-engine red or add nautical touches with fish netting, oars and a life ring on the building's door to create a suitable hideout for a bunch of little pirates.
  
  

Pool Storage

• Place a metal building in close proximity to your backyard pool. In the off season, you need a place to store lawn furniture, pool inflatables, pool skimmers and chemicals needed to condition the water. During the summer month, store your pool cover and winter items such as shovels and a snow plow. A captain's wheel or crab pot floats add a nautical flair to your metal building.
  
  

Creative Retreat

• Artists and writers alike covet quiet, out-of-the-way spot to pursue their passions. A moderately sized metal building can be purchased and placed on a concrete or treated-wood foundation in your yard. Free-standing book shelves, an old door placed on sawhorses of two filing cabinets¸ a chair and an easel are an artist's basics. A laptop computer is an added necessity for a writer. A window is a bonus for writers, and the natural light is a requirement for artists. If your yard is not quiet, consider installing sound-deadening boards inside the metal building's walls.
  
  

Garden Shed

• All serious gardeners need a potting shed -- a gardening shed to store and work with garden supplies. Line the metal building's inside walls with counters and open shelving to hold supplies and plants in different stages of growth. A counter outside the building provides an extra al fresco place to work. Match the metal building's style to the landscape around it.
