Is there part of the house we can't see? Where is your front door? Just the double frontage like that is plain, but that was the style and not much you can do about it. The homes you are looking at do have a lot of features with opportunities to bring in other colours but there is nowhere with yours to do that and if you try it usually cheapens it. If you take the triple fronted house you posted, I would do the lighter green on the weatherboard and the deeper green like they have used on the window frames, I would do for the baseboards and the front door. I would keep the window frames and eaves white and paint the guttering to match the roof. Are you country? Are here any water issues for the garden? Instead of trying to do something with the house, I think I would be inclined to give it all a cottagy look with a picket front fence, nice entrance, a lush lawn and lots of plants for colour and lushness. The dark green baseboard will be a nice background for some small shrubs in front of the house. Weatherboards really lend themselves to that look. Don't forget the addition of old tyre swans - lol I notice you have small awnings over the windows - maybe replace them with some striped canvas ones in greens and terracotta - if you can get the combination. [houzz=]

realising that you did not mean to have one long narrow room but i think we all recommend an L shaped extension (not necessarily my suggested plan) because it will be much more cost effective than removing the whole back wall of the house and replacing all the separate ceilings and windows and not achieving much more than an enlarged bathroom, bedroom and small ensuite..the Lshape extension of similar sq m would create a more comfortable floorplan for the whole house with a simpler extension that also has the potential for a deck or alfesco to enjoy the bush view..photos of the roof and back of the house and measurements of the distance to the side and back fences and location of the pipes you mentioned and rough measurements of the bathroom, laundry, wardrobes and short hallways would allow a much more detailed floorplan to help invite more suggestions

Update on this. We have decided to keep upstairs unchanged in terms of layout. We will live in the house for a period before making any layout changes upstairs - 2 Bedrooms will be for our girls, while our son will sleep downstairs in the living room (now bedroom) as this was seldom going to be used. Now we are looking at the kitchen design - photos attached of current kitchen which will be completely refreshed along with the tiling in the kitchen / living area. Looking for any ideas on how to best update the kitchen - notice under the stair case is not currently being utilised but we would like to perhaps have the fridge or pantry under the stairs to include this dead space. From the kitchen window to the stair case is 4950mm x 3200mm approximately depth of the current kitchen. The stair case hangs into the kitchen around 750-800mm. Wondering if it would look silly to have perhaps the fridge built here and this cabinetry would sit proud of the bench space next to it, but we could also install deeper bench space to balance the look... We are planning to have the eye-saw built in fridge space currently in the kitchen removed altogether.

Yes, I can't help but feel that I will regret moving the entry @afjp! My husband is keen, but I know that I'll hate it, walking halfway down the house just to enter. Thank you for your suggestions. @oklouise, you really have gone above and beyond - giving us a lot of food for thought! Thank you for taking the time to fiddle with our floor plan. Lots of options there. We can't go toward the front boundary anymore, unfortunately, but I like your thinking! @siriuskey, thank you too for taking the time to share your ideas - It is much appreciated. We did toy with the idea of using our existing living and dining like what you have, but I think I am leaning toward the open kitchen, living and dining at the back. You've used up every inch of space, it's great! Some more ideas for us to think about. Thanks! Just a question for those in the know-how much would it cost to move plumbing etc? And what would your ballpark $ figure/budget to do this extension be? (how long is a piece of string, I know...)
