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.

There is no common link, no continuity that each dwelling share. i would introduce an element to both structures, borrowed fm the other, so for example the red brick and windows are the most striking design elements in the house, however the rendered garage with a parapet and no visible roof may as well be from another planet, I would brick up the front piers aside the door, with matching red brick, and then I'd install some post and beam rafters that could extend over beyond the garage door, almost like a flat eave, however just beams, no roof, and paint it chacoal, I'd then link a path from th garage to the house, and create the same detail at the porch entry of the home, same beams, colour and materials, so it looks like they belong on the same property. also, perhaps a little scary to consider, i would render the wall in between the door and the first window only, and paint the front door in the matching blue. Windows I'd go charcoal as per th beam structure, and apply a stained timber batten to the flat parapet above the garage, so paint that black, then fix timber battens vertically wh enough spacing to see that black shadowline, it will modernise it, emphasising the elongated design, which is both contemporary and popular, and tie this timber detail into the house with a generous deck. Both timbers will link, over scale th deck, perhaps stagger a step or two, as the garage is over scaled also. remove the fence, and landscape the corner with over scaled shrubbery, a meandering path to help invite ppl between the two structures., the visual disconnection is the fence, but it translates into everything else. if a fence must be, then consider a half height one, or an informal row of sleepers as uprights, to softly define the yard.

We are also building in Christchurch :) So also had to look at these kind of requirements for sun, but we had a much smaller section to work with (800sqm). If cost is OK ideally a 2 story would get light into more of the rooms. You also saod the street frontage is 35m but the plans say currently the width of the house is only 15m, so you could run more of the house along the frontage to get it aligned with North. Its a big section are you setting it very far back from the street? Or are you worried about privacy? Is there a view Northwards, otherwise if you can set back from the street and add hedging or plantings to increase privacy I would try and align as much of the living space to get the North and west sun. Depending on what your roof is like you could also add a clerestory to get light towards the back - we are using skylights as well for our back hall and bathrooms to make sure they get as much natural light as possible.

We began this renovation process, first looking at a range of photos of the bones of the home with our client and about her expectations and "Ultimate Investment Goals" for her project (family home or rental, long occupancy or flicking property, ideal uses, pets bedrooms required etc). We then looked at the structure of the existing home and its potential. With a few tweaks to the layout, we could gain 30sqm and by pushing the exterior wall out at the back and side on the ground floor we could gain another 40 sqm by taking a 3 bed 1 bath single car garage to a 4 bed 3 bath, two lounges and study with double garage. There where some aesthetics that benefited also - the house was brick base with nobly brown brick. Our extension removed most of this and the remainder we rendered, the upper floor cladding was leaking and had a heavy concrete tile over it by changing to weatherboard and tin (longrun) roof the loading's on the existing foundation where similar so no existing foundation needed upgrading. To give it a modern spin we used a block for the fire boundary wall and used stack bond pattern to front and back. Our client Debbie works with raw food as her job, making gluten-free vegan food, so her kitchen space was very important. With the kitchen landing close to an internal corner we decided to make it wider than normal along the back wall hiding a step in the exterior wall and helping connect the two living rooms with a Stainless bench on the island this helped to break up space and provide a central gathering point for entertaining. Finally, we upgraded all the wiring and plumbing and gave it a good paint and carpet throughout. We conducted weekly meetings throughout the entire process of the renovation, not only to discuss options and check we where on the right path with the design but to enable a spread out approach to the loads of decisions that go into a build/renovation.
