How about some pictures?

My thoughts are either you keep it a sort of brown but with a more greenish undertone and less "pinky". Resene Pravda would work beautifully. (I have done a house that also had brown joinery). I would change the garage doors to "blend" in with the house colour - don't try to accent them too much. The fence, if you go that direction, would be an even darker "brown" to create a bit for interest and create a bit of depth as you look at your house - Resene Marsala?? Option 2: Go completely different and head back to "white" with a grey edge. I would go for something like Resene Triple Seafog, Resene Double Merino perhaps. What I am thinking is basically a white that has a hint of grey in it to tie in with your blue roof. Once again, don't want the garage doors to be that "light" (ie. the house will look virtually pretty white overall) so probably go a very pale but light grey for the garage doors (Resene Silver Chalice/Resene Quarter Atmosphere). The fence would again head to an even darker grey like Resene Double Stack. The ballustrade could either go back to main house colour white or you could use the same as the garage doors. If neither of these two options appeal then look at a beige but not too much of a yellow undertone. Also have a chat with your local paint shop. Always use testbots. Colour is like a chameleon so it will reflect its surroundings. Love your front door! Perhaps one large, tall as you can afford, pot with a statement plant - wait will you've painted the house first so you know what colour pot. Let me know how you get on.

I'm not a builder or an expert . The downstairs looks easy -- obviously you want exactly the same width and profile -- take 1 or 2 boards off the end of the house , add new boards , paint the entire thing . The garage will 'hide' the existing side wall , so that can be left as it is , relined , painted , whatever you want , as its now an 'internal' wall . Upstairs though is trickier -- I assume there are horizontal weatherboards along the side of the house , so adding across and 'around the corner' would be more difficult , but not impossible -- it will take more labour and a bit more materials . At the end of the day , talk to your builder -- they are the one that will asked , so if they say No , pretty much the end of the conversation -- you accept , or you look for another builder , who hopefully says yes , and even more hopefully , actually can do it haha !

You would need to talk to them . I 'almost' can't see why not , but here's a couple of problems -- -- a toilet obviously needs water and connecting to sewerage . So that means both need connecting to the services in or near your house , almost certainly underground . Is the concrete floor in the line between where you want the toilet , and where it will connect ? -- the toilet probably needs to go through the floor -- I doubt they would let you go out through an external wall then down . So how thick is the floor , is there reinforcing ( you'd hope there is if you are parking vehicles there ) ? That will need 'breaking' and cutting , and may weaken the floot . ASnd it will cost $$$ . -- you probably want a basin and tap too . Do you want hot water too ? That may be hard to get from the house , so you may need another water cylinder , presumably small . I doubt if they'd let you have a gas califont and bottle , even if you tell them it won't be used much . -- Now , lets talk about things like a shower too -- not much harder , especially if you are having hot water . And maybe taps for a washing machine -- gives some versatlity . BUT heres what I think the biggest problem might be -- some slum-lords will rent out a garage to a desperate family of 4 or even 14 people . Almost all these slum-lords don't seem to have been born in NZ . Your name implies a similar background . Unfortunately they may think it is easier to decline now , rather than have to act later , so may use the bad few against the better thousands . I have heard they will decline everyone if they think this is a possibilioty , so it does make it difficult -- they aren't prepared to take a risk . Talk to them and see though .
