Hi Richard The first thing to check then is what the rules are about putting anything on that roof. A deck there will have limits to avoid overlooking, and multi-story, issues with the neighbours (I have first-hand experience of these rules :-) ), which will establish a boundary of how far you can go. Then there is the fundamental structural question of what you can put on there. Then there's the question of what you can afford... For me, a simple and cheap option would be to put some tall plants/planter boxes toward the far edges of the roof, tiering to lower plants at the front. I'd take away the plants in front of the stairs at the garage, and have smaller/narrower plants up against that garage window wall to hide it, and also away from the side steps from your upper level. That makes the roof part of the garden view, and maximises the terrace area (remove encroaching plants), and hints at 'more' around the corner, down the steps. With a bit more money and appropriate permission, a deck on the roof gives you another whole space to play with. You'd have to work out where the best access to that roof deck would rise from, without losing too much of your current paved area. Connie's idea for a bridge could work well, but would seem to interfere with the access to the current paved area? With a lot more money, permission and some engineering, I'd be really tempted to build a deck on that roof and extend it full width right back to the house, at the same level as your door/windows! That way you bury the garage (and small terrace) under a much larger area, giving you heaps of options for creating spaces. You can use the old terrace then for storage (e.g. gardening materials always take up space, and more garden = more materials; compost heaps, worms, bikes, ...). Even if you can't take the deck all the way to the front/side of the garage, you can still create a whole new area there. And you can surround it with plants even if you can't build to the edges. I love spending other people's money :-)

Two plants I can suggest that I have chosen for my garden, are virtually unkillable, will grow in almost ANY soil or weather conditions & require little maintenance are: butterfly/african iris & Celtic Cascade tree. Both can be left to go a little wild for a natural look, or be cared for, to fit perfectly in a more formal garden. In regards to the iris, I removed my entire garden of mature, property damaging trees when I moved into my new house, but didn't want to wait years for a new mature garden, so I searched online for ppl selling/giving fully grown specimens away before they did renovations or re landscaped! The plants were a cinch to dig up, replant in my heavy clay soil & are thriving! I even cut some of them in half before planting and it didn't phase them!

Can you post a sketch? I'm scrolling back and forth trying to visualise it all and understand dimensions and orientation and usage. If the fence colour suits the house and creates a good background for the plants I wouldn't worry about whether it will date. The same concern could apply to the house, but if it all comes together in a way that is classically timeless rather than overly trendy and you're happy with it, then it's working. Alternatively formal or informal hedging can obscure the fence and avoid the question of what colour the fence should be. I agree that with a toddler and dogs you want to keep as much of that lawn as you can. Work out how much garden bed is needed around the edge so that you are not constantly pruning the plants back to fit, but so it still leaves as much lawn as you want. What's missing in my view is edging, most garden styles look better with edging between the plants and the grass. Another thing that gives gardens a more finished look is underplanting. Research plants to ensure you don't plant anything that is toxic or allergenic. Remember humans and dogs can differ in that regard. Start an Ideabook for your garden. If you have images of what you are trying to achieve, and you can share that with us, you can make progress with specific how to's and choosing specific plants.

I’d use a Pandorea Lady Di to climb. It will need some support but it has flowers for the bees. Apart from your fruit and veg I’d aim for all natives. A hedge around the boundary of a Callistemon or 20 would be lovely. They will need a trim but won’t grow high enough to block sun. You will need a feature tree or two, because you have room and it will be a shame not to. My current favs are Corymbia Ficifia, they are in bloom at the moment.
