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.
Real Stone : Stone has the most natural outlook, most durable but also the most expensive type of patio materials. It require good skills to install because each stone greatly varies in shape and size. Additionally, mortar compound is used to adjoin these stones and settle as they dry. It is designed to wear well in high-traffic, need little maintenance and could last for decades.
