Layer Colour Coded Ground Plans

To help me take my ground plans onto the next step which is to envision my garden from eye level instead of a flat birds eye view I took my ground plans and worked out layers building up my garden. I then colour coded them and started to use a key to label different aspects such as paths. However, I realised that with it still being flat and looked down on I couldn't label most of it just yet.

Now that I have these layer coded plans I can rough them out in maya and use renders from there to draw on top of.
