Sorry, being flippant. As stated, this is a British based forum and, while there are all sorts of levels of experience and skill, we mostly haven't a clue about soil/weather/environment in your neck of the woods.
Have a chat with your neighbours about why the chicken wire is needed. Over here we are encouraged to make holes in fences and boundaries so critters like hedgehogs can wander between gardens to find mates and food.
Think about what you want from your garden - play, relaxation, sitting, eating, flowers, perfume, vegetables, fruit, wildlife - and then how much time you have to spend on it each week to maintain it - the horticultural equivalent of dusting and vacuum cleaning - and also your budget because that will dictate the style and content as well as whether or not you need a greenhouse and cold frames for sowing and pricking out your own plants, taking cuttings, making divisions and so on.
Then work out which way it faces, how much sun each bit gets and when and you can work from there. We'll be happy to help if we can.
