Stone Veneer : Stone veneer generally contains most of the benefits and advantages of real stone and it is comparatively a lighter type of patio materials and less expensive. Stone veneer can easily be cut with most common types of saws. Generally, most people will lay out their veneer pieces ahead of time so they can cut pieces to fit in odd spots in advance. It is also as durable as most other patio materials. It requires very minimal maintenance. In addition, stone veneers are much easier to find in the market.
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.

Allow around £120 per square metre as an all-in cost to get a contractor to lay your patio.
