We got the IKEA shelves that are pictured in the butlers pantry photo I posted when we were on holiday in Melbourne, Australia. We don't have IKEA here in New Zealand! Hubby is going back over in May/June so will get him to get more of that sort of thing when there. We would pay about 4x the price for that sort of thing here in NZ. I need to work out what I will do now where the fridge was and there is the angle change (does that make sense?).

I don't think that you will have a problem without building a study........ The extra garage space will be a valuable asset...........and can do double duty.....

If you are seeking a truly open feel to the floor plan you have shared, then using one material in the mail living area is the best approach to making this space feel truly open. Using a variety of materials on flooring chops up the space and decreases the visual footprint. I would suggest using wood, tile, or if you are on a tight budget laminated flooring for the living/dining/kitchen. Then use carpet in the more intimate spaces; bedrooms and possibly hallway. Save the tile for the bathrooms.

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.
