Having no trees in your garden can be a problem when your children would like a tree house. This is what we did to make a compromise. The tree house shed is built around four fence posts, which are cemented into the ground. The plan is to eventually make it look like a tree house without being in a tree. This is my first attempt at building a shed or tree hoose and have enjoyed the challenge...well, most of the time, hehe. The tree house has a front door and also a trap door as requested by my son to access below which will eventually be fitted with wood as a basement. The hoose is not complete as yet and has taken two weeks to date so far and about £380 for material, which I feel has been well worth the money and effort considering the extra time this will give me on a Saturday watching the football, yeha!!
