Build a climbing wall at home with an adjustable overhang

My climbing wall took one weekend to build and costs around £300 and half off that was spent on hand holds.

There are lots of online resources for building a climbing wall the following links I have used myself while building my wall:

Step 1 Find a space

Most home climbing walls are built in the garage but as there wasn't enough room in my garage I decided to build it in the house. I chose a room downstairs with plenty of room and a tall ceiling (anything around 10' is good); avoid using a upstairs room as this may put strain on your ceiling when you fall. You could build a wall outdoors if you don't have any space inside but you wont be able to use it all year and the wall gets damaged by the weather and changes in temperature.
