The choice of screening will depend on available budget. Walls are expensive to build, wooden screens with posts and trellis panels are much cheaper. Planting a hedge is usually the cheapest option, but may take a while to grow in unless you can afford large plants or an instant hedge.
Creating privacy : If the patio is overlooked the patio design will need to include screening. Walls, hedges, pergolas, and fences can be included in the patio design to provide a sense of enclosure and privacy. When building a wall around a patio it is a great idea to include a window through to other garden areas so that the patio doesn't end up feeling to claustrophobic. Windows in dividing walls create an interesting glimpse of the rest of the garden without compromising privacy.
A patio is just one element of a garden design, but it is one of the most expensive parts of any garden build. Because the patio fulfills several different functions it needs be given careful consideration. Here are a few pointers on how to design a patio.
Intended use of the patio : Decide how you want to use the patio. Is the patio mainly for alfresco dining or sunbathing or relaxing with a book or all three? The intended use will dictate the size and location of the patio. A patio mainly for dining is best placed where there is some shade so that diners can keep cool on warmer days and seek the sun when the weather is cooler. A patio intended mainly for sunbathing needs to be in a spot where it's sunny all day. If you want young children to safely use the patio, it needs to be somewhere you can see them from the house.
