couches, angled island, powerpoint on island are good bt having dining table so far away frm kitchen not practical...I can imagine a tiff everytime the table is to be laid...who is going to ferry all the food and cutlery up and down?

if the original asbestos walls are in good condition then they can re-be painted but if the walls are too damaged to be saved the asbestos needs to be removed by professionals and the cladding replaced, no reason you can't have different profiles on the front and sides as long as joints and corners are sealed properly but if you plan to install new windows it could be better to wait to repair sections of wall as the windows are replaced (i'd prefer to have all the roof and external walls in good condition and then do the internal work at leisure)... .modern fibrous cements are excellent ...we've just used flat fibrous cement with curved battens over joints and very happy with the results for our 50's house (there are several different brands available through the big hardware stores and research on line is much easier than trying to work out the variations in store) the gabled portico can be made as a separate structure or as a extension to the roof with valley gutters depending on placement of the solar panels (and/or solar panels can be moved)

What about installing some wires/trellis to train potted star jasmine? The benefit there is fast coverage, looks attractive from both sides year round and smells good when in flower. You could put in some simple rectangular pots for the jasmine, along with a few feature pots with other plants Eg. Patio-suitable citrus. Do you have information on climate/personal tastes etc. (A few things to consider... Height from ground/access to trim a creeper such as the jasmine, weight of pots/soil, water run off from watering)

I was just thinking of making more of a substantial open living space, in terms of the extra floor space to the east, as I can see it being the part of the house that we would be in all the time. In terms of the north side, we are on a corner block and so there is a 4 metre setback on that side, which we are already at. I don't know much about these things, but I assume that wouldn't be able to be changed. I am planning a nice garden on that side of the house anyway, which I am excited about, and we like to have the space all around the house (i.e. no fences close to any of our windows, giving the feeling of privacy and space in a modest suburban block). The other thing I think of a lot is regarding passive solar design principles, and having our house oriented the way it is (West facing), I am reluctant to do anything too major unless we can really capitalise on this. Having the bedrooms on the northern side does work really well for us at the moment, as we use them a lot - with small children napping and my husbands office being on that side. Although that will change when the kids grow up... I'm hoping we can at least add some skylights or something like that into the extension area/kitchen in order to bring in more light. Our kitchen is quite dark and cold in winter.
