Keen to hear if any community members can recommend programs or apps that they use to draw quick and easy floorplans.
Like @2Belindas Pen and paper for me initially, then I use a program called 'Smartdraw' to put everything together. This program has heaps of templates and you can even insert furniture to see how everything lays out. This does cost however I am pretty sure you can download a trial version. Can be a little tricky for first time users but has a very good user guide.
I also use this for electrical wiring diagrams and landscaping layouts.
@Isobel, that does look good. I may have a play with that in future.
