How to build a fireplace with a bench for your own garden.
Working time approx. 2 days.
Use a pole to establish the center of the fireplace. This will be a reference point so make sure to use a long pole. Use a string and some spraypaint to mark the edge of the fireplace.
Then you can start digging... To find the right height you can add sand and some cobbles. Make sure the height is approved by apropriate authorities (wife, girlfriend, whatever) and then make sure this stays where it is as this will be another reference point for you.
