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.
Including built-in seating : Patio designs incorporating built-in seating with pergolas and outdoor fireplaces look very chic and transform the patio into an outdoor room. It is also a great way to make use of all available space in a very small garden. This solution is convenient if you don't want to shuffle around with garden furniture. However, the position of the seating is fixed and restricts how you can use the patio. The space is less flexible as seating cannot be varied to turn a dining area into a lounging area.
Location of the patio : Most patios are sited immediately adjacent to the rear exit from the house because it is convenient - this may not be the best location for your patio. The back of the house may be shaded all day and therefore not ideal if you wish to like to sit in the sun. Consider a small terrace to the rear of the house with another seating area somewhere else in the garden which gets more sun. When designing a garden it's a good idea to include more than one patio.. One patio can be sited so that it catches the last of the evening sun to provide a warm spot for an evening drink or meal. This makes the garden much more interesting and ensures that you are using more of the garden.
The materials you choose should always blend with the surroundings and other materials used in the garden or landscape, while providing the right surface for the intended use of the patio.
