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.
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.
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.
Cheaper Indian Sandstone is not always the bargain it appears as it is thinner, or poorer quality and more porous causing leaching of the minerals in the mortar onto the top surface of the stone.

The more expensive options are Travertine, York stone, Basalt, and Marble.
