Same with concrete. So you build the first floors to suit the car parking and make a platform to go up with timber from that point.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-embed-handler wp-block-embed-embed-handler wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"youtube-embed\" data-video_id=\"Z0dnPEPlebU\"><iframe loading=\"lazy\" title=\"A Guide to Wood Construction Systems : Greg Nolan\" width=\"696\" height=\"392\" src=\"https:\/\/www.youtube.com\/embed\/Z0dnPEPlebU?feature=oembed&#038;enablejsapi=1\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/div>\n<\/div><figcaption class=\"wp-element-caption\"><em>Professor Greg Nolan has previously presented a Guide to Wood Construction Systems.
