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. There are some inexpensive granite slabs currently available that make a wonderful surface only slightly more expensive than Indian Sandstone. The more expensive options are Travertine, York stone, Basalt, and Marble.
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.
Stamped or Colored Concrete : This material is gaining popularity and very practical. It often can be molded or stamped to look just like other types of patio material such as brick, cut stone, irregular stone, cobblestone, etc. It comes in various textures and colors and is cheap. Stamped or colored concrete is a very practical solution when working on a budget.
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.
