Choosing the surface material : The most common surface for a patio are paving slabs. There are many different types of paving slab with a wide range of price tags. Steer clear of concrete slabs - they are often more expensive than natural stone, will fade over time and always end up looking fake. Indian Sandstone has dominated the paving slab market for years as it is cheap, natural, widely available and looks good.
All the above mentioned are excellent patio materials to be use for your patio. In addition, you can even use a combination of different types of patio materials to make your patio comfortable. Also, you have to consider the drainage properties of each material. For instance, individual stones, bricks, or pavers will let water through more than a whole slab of concrete.
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.
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.
