I have a great visual imagination. I can see things really clearly in my head - how they will look, how big they are, how things fit together.
However, I realise not everyone is this way, and so I've decided to do some floor plans of the two cabins I'm looking at and then I can discuss them more easily with the other half.
I've decided to use https://floorplanner.com/ to do this as I really like their interface, and things seem really clear and easy to use. Also, they do 2D and 3D visualisations which I think will be helpful going forwards.
