Thanks for making these videos. I am doing an odd-shaped garden room and this has been very helpful and I've also used Ali which great for the structure.

Hi, I'm planning on building a garden room that is also an odd shape. Would you mind sharing your SketchUp file or 3D model? I would love to see how you constructed those corners

Hi, whats your wall height if you are using 5x2 for flkoor and 8x2 for roof and furrings on top of that ? also interested in your door height (non standard I assume). I am trying to optimise my build within permitted and trying to get maximum headspace and interested in how you tackled it. is your internal height with plastboard and flooring fitted about 2050mm ?
