That internal slide would be super fun! Especially if you have more than two levels to your home, like a townhome.

Without knowing what style or colour the Colourbond is , it's pretty hard to make suggestions -- oklouise has shown some stunning looks , I'm trying to think how to do something more on a budget ? Using JUST your photo ( i.e. assuming it had the wooden fence still ) I would have waterblasted and stained all the wooden fence ( the one that appears unpainted , the white fence on the left , etc ) in charcoal/black . The white gates I'd redo in white , but with one proviso I'll get to soon . The veranda ( portago ? ) I'd tidy , or replace if too far gone , with new materials . If going new , possibly also stain in charcoal , or a redwood stain , but keep the roof in crisp white . So to this stage , it's tidy but a bit darker , a bit more modern , but pretty boring . So add colour -- the front door , the garage doors , possibly the upper level gutters and downpipes , and the centre scroll in the gates to the left -- all in a stand-out fire hydrant red or sunshine yellow or citrus orange -- I'm hesitant to use orange , as combined with the brown , it may emphasis the 70's aspect , but if there is a barge board around the garage doors , then citrus orange doors with crisp white surrounds would look smart ! Depending on the veranda , and what work is needed there , then maybe $1000-2000 in materials and paint , and 2 days to a weeks work , and it would look more modern , less boxy , more 'happy' .

What a gorgeous house, great ideas from Kate, I would paint your trims a dark colour, you can see how beautiful it looks with your colour bricks, landscaping along your fence line would instantly add a beautiful look, plant up bed at mail box, some gorgeous planters at your front door, just lovely

regardless of what we might want there is not enough space for a vanity in a room less than 1200mm - 1500 deep.. assuming standing space of about 900 x 900 and a vanity about 450 deep ...the only way i can see to make enough space for a vanity would be to push out the wall and make a bay window alcove but you may not have enough space outside the wall before you reach the boundary and would probably also need Council approval to change an external wall my suggestion for the moveable island (eg IKEA has big kitchen trolleys and storage tables that might suit) and that can be moved to allow for the dining table to be rotated or extended into the kitchen for more comfortable space for an occasional crowd .. small walking spaces are tolerable occasionally but fixed narrow walkways less than 1m on all four sides of the island will side defeat the goal of making the rooms feel more spacious and i would also be careful about adding extra storage that is hard to reach and would need walk around the island to wipe the whole surface...much more than 90cm deep is too far for most arms to reach ..there are many other options for extra storage eg by adding tall wall cabinets and maximizing the basement storage for seasonal supplies and a proper cold cellar and use the moveable island trolley for most often used supplies and you can improve the corner cabinets by making them 1050x 1050 (ie with double bifold 45cm wide doors) instead of the standard 90x 90 corner cabinets with 30cm wide doors.... BUT i had another look at my first suggestions from last year and i still think that a more generous ensuite stolen out of the basement space would make the most comfortable master suite, moving the bedroom door allows much better location for both the new stairs and plenty of space for wardrobes, king bed and a bedroom chair instead of the tiny master suite and don't forget the low storage wall in the dining room for dinnerware, glasses etc
