A local garden store or designer will certainly be able to help you. In the meantime, you can look up ideas online, but you'll need to know some basic information before anyone can help you choose specific plants. The first and most important is to know your planting zone, which is all about your location and climate. You also need to know the directional orientation of your house and the wall, and whether it is "full sun", "partial sun", or "shade". Will you be planting on both sides of the wall? You may wind up with vastly different plants if one side gets full sun and the other is in the shade. Take into consideration whatever shade is cast by the large tree, and the house itself. If you have the time, spend a day taking pictures of both sides of the wall - maybe once an hour (shadows will shift somewhat throughout the season), so you may want to do this every few weeks and keep a visual log of how the shadows move. Also, before you plant, decide if you want to paint the wall. It will be easier to paint before you plant, of course. White will reflect heat back onto plants. Climbing plants would look nice on the wall, if you're not going with a very structured garden. Ivy is an obvious choice, but there are other vines that flower beautifully, if you like that idea.

The fence will end up being a modern picket fence, We aren't sure if we should grass the two squares or plant it out, it's a nice sunny spot, but we have nosey neighbours that we are trying to make disappear, if then it becomes more private then a seated area could be really nice, Hopefully the right plants will work or we will have to go with plan B, of installing barbed wire and two wild Dobermans!

And I would be planting trees – real trees not dwarf versions of trees and no more palms (unless you want to have palm tree themed garden – in which case a lot more palms are needed). I am not advocating planting forest giants but there are trees that will provide shade, shelter and a sense of scale that you won't get from yuccas and buxus and mondo grass and succulents alone. But before you start buying those trees you have a few decisions to make and a bit of analysis to do. 1. Orientation – you need to understand the basics of winter sun and summer sun, how much westerly sun you welcome and how much you need to shelter from it; where your prevailing winds blow from and whether this changes with the season also. So, once you've worked out where you want the sun to penetrate and at what time of the year, how to allow for wind, frost, whatever... you need to 2. Decide if you want a predominantly native garden, a range of deciduous trees or a completely eclectic selection (like the best 'English' gardens – which are planted out with plants from all over the world – Indian subcontinent, Asia, Africa, The Americas etc. Even some from Australia!). 3. Now the tricky bit – what do you love, i.e. which trees and plants make your heart really sing – and hopefully for more than two or three weeks of the year? Once you have that list which of those are likely to be happy in your climate, in your soil and with the amount of gardening attention (watering, feeding, pruning etc) that you're likely to enjoy lavishing on them. Your long list will by now be a much shorter (and more manageable list) but trees are what make a house look bedded in and part of a landscape rather than just sitting out in the open in a way that is both self-conscious and a bit awkward. Although, again I guess you could embrace the suburban awkwardness and go all Howard Arkley in which case keep it all small and suburban... But it is your garden and your house – make it look like what you want your house and garden to look and feel like! Good luck!

I am not sure you need to add a deck or raised paving, when there is a usable surface there already. You will have gained a closer connection to the living area, but you will be more exposed, both to neighbours and to the wind, for a significant cost. Raising the fence may break height restrictions, as mentioned, and will also really box you in visually, especially with overhead louvres. Those may feel too low over a raised area if at eave height, and if higher could look awkward against the house. The fence already shades the area alongside it, so I wouldn't extend any further shading right out to the fenceline. I would consider a shade sail before louvres, both for cost and for a lighter, less boxed in appearance. Is there access to bring in a large tree? A good sized deciduous tree positioned near the fence at the edge of the lawn may be a good way to get some attractive summer shade, autumn colour, added privacy and may be cheaper than a set of movable louvres! Below the new doors from the living area, create wide steps These could wrap around to meet the existing steps. Wide steps can become a casual seating area as well as create a connection to the existing paving, and they are less of a barrier visually than a small set of steps. They could incorporate a planter, which will help to soften an otherwise quite hard outdoor space. This would also allow the lawn to remain connected with the paved area, making it feel larger.
