So now you have heard from a local beekeeper. 
If you wanted to use 2 boxes, it wouldnât hurt the bees. You just have to be careful not to give them too much space to defend, plus be very careful not to leave dead bees around after inspections, because you have a nasty SHB problem in your part of the world.
Awesome thanks guys. Have chosen the spot in the garden beside the chook house for the hive. Just finished planting about 40 lavender and rosemary plants to give them some local flowers. 
Two brood boxes is not so much a US thing as a northern US thing. People in Georgia usually run one brood box. People in Tennesee and North Carolina usually run a deep and a shallow. People in the far north run two deeps usually with some running two deeps and a shallow. I run between one and six eight frame medium boxes depending on the size of the clusterâŚ
Spring Update - So the first day of spring is here and just to remind me of what that means my hive decided to swarm. Fortunately I was able to capture the swarm and I have them nicely settled into a nuc box. I knew they were starting to get crowded so I had put the nuc together last week and finished painting it on the weekend. I had not even done a first harvest yet. I have some photos below albeit they are a bit disjointed because I was on my own through the whole process. Anyway pretty proud of myself having achieved all this on my own.
A couple of questions though for the experts.
