Definitely the step back roof line. For your home, this would be my choice of a garage door. Let all the windows of your home be front and center, so no windows on the door. Also, make sure you have lots of outdoor lighting. It is worth the expense.

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!

A nice flowering hedge would give you height to disguise the bathroom windows and seasonal interest. Michelia gracipes or a camellia sasanqua both cope with shade and can be kept clipped tall and narrow. Michelia is also fragrant as are some of the camellias.

I didn't see this either , and how long is a piece of string ? Wellington ( a bit like parts of Queenstown ) is known for steep slopes and high winds , so the actual design will affect things a lot -- my sister once 'conned' me into moving her to Wellington when she got a Government job . We loaded one of my small trucks and drove several hours , when we got to her new place on the side of Mt Victoria with lovely harbour views , it seems she had forgotten to mention that the new house was the one up there -- yes , a 1920's build 130 steps up from the street . Hard enough moving a glass fronted china cabinet and solid Kauri 1880s dining table -- imagine carting every bit of timber , tile , window , kitchen appliance up there !
