After the short supporters were positioned operations moved round to the 2.5m side of the treehouse requiring ‘long supporters’

First the bases were carved out as before. So far this has remained a ‘tree house’ i.e. we have no support from the ground. We are trying to stay ‘pure’ and not touch the ground – lets see what happens over the course of the build!

 

Now for the ‘technical’ bit. We jack up each cross beam to a) make sure they are all on the same level, and b) counteract the ultimate load they will bear from the weight of the walls, roof, contents and occupants. You should see the pages of calculations I had to do before we knew how far the raise the ends of each cantilevered cross beam prior to the supporters being positioned underneath….!

 

 

We used an essential piece of kit – the Hi Lift Jack – shown above and below. It’s really for helping 4WD vehicles get out of sticky situations but we have found another use: jacking up our tree house foundations!

 

 

 

 

 

 

We set the ends in position first then worked on the intermediate sections.

 

 

 

 

 

Looking good so far – and we haven’t touched the ground yet!
