Log cabins with flat roofs - this Lugarde video should be viewed together with the Lugarde log cabin instructions that are supplied with every cabin kit.
Following printed installation guides can sometimes be a tricky to understand what you are trying to do - a video makes life much easier (a minute of video replaces pagaes and pages if text which can end up being gobbledygook and no use to anyone!).
These generic video guides should be a tremendous help to you BUT should be viewed in conjunction with the printed installation guide and parts list that come with your building - of course there is nothing wrong with watching them before your building arrives so that you know the basics and already understand what needs to be done, but we then recommend watching the videos again once you have your plans and parts list to hand so that you can refer to them whilst watching..
