Consider the long term practically and maintenance of patio materials carefully....Most people only think about materials in terms of the cost but that should not be your only consideration. You don't always require the cheapest patio material. On the contrary, you also need to think about what patio materials are going to last for a long time and what kind of maintenance each type of material needs.
Polished concrete makes a wonderful contemporary surface for the patio. Resin bound gravel is not only great for driveways, but makes an excellent contribution to the patio paving when combined with other materials for textural contrast. Get the best quality stone you can afford then the patio will last longer and stay looking good for many years. A patio should never be designed in isolation without considering the rest of the garden. A well designed garden where all the elements are in scale with each other and the house will connect the house and garden. A balanced design that includes a patio or multiple patios will give the garden coherence and ensure that it is a pleasant, comfortable space in which to spend time.
Decide on the budget : Installing a patio is expensive but it is worth spending as much as you can afford as the patio is such an important part of the garden. The garden should be viewed as an outdoor room and if you are prepared to spend a little extra on getting it right it will be useable for most of the year. Allow around £120 per square metre as an all-in cost to get a contractor to lay your patio.
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.
