Running with your second floor plan (and ignore the glass sliding doors in this image) but would you consider changing your 3m narrow splash to a full sized fixed window on half the side and the remaining side create as the cooking area with cupboards, oven etc.? You mentioned you have stacker doors in the direction of the lounge, but in terms of space, from these doors, it's living area no windows at a room length of around 7m, followed by 4m kitchen room length including a 3m narrow glass splash to provide natural light for the kitchen area (cupboards noted above)? From your drawings there seems to be no windows on the opposite wall, is that right? I feel you will need to bring additional natural light into the kitchen area possibly bigger than the 3m glass panels if only 0.6m tall (or similar) especially with cupboards on top. If you're not keen on swapping out the narrow splash here's another example with your second floor plan (and also ignore glass sliding doors in this image) but possibly a tall window or fixed glass panel before your kitchen bench starts - even if <1m wide. Or greater than 1m if you're OK to encroach on your 3m glass splash and make it shorter. If the island bench is not a "must" you could create similar to this image and have a L-shape bench so it encloses the kitchen a bit more. This will help create the next room of your house ie. Kitchen - and you'll gain a few more cupboards if you're really wanting additional. Then have the big fixed window adjoining the L-shape next to the seating bench. You could still have your narrow glass splash with cupboards above, possibly just shorter (only referencing the L-shape and large door in this image - imagine fixed glass full-size wall panel in lieu of door next to the seats. Ignore the remainder of the kitchen). Is this an existing dwelling or new home build? For either of your options, are you impacting your roof-line as your first floor plan suggests you're widening the kitchen by 1m? The first plan I'm guessing will cost more; light wells and extra bricks vs straight wall. As mentioned by the other posts, there's plenty of storage options. You still have a decent amount of room for cupboards including a full-sized pantry next to your fridge space. I also agree with jbantick's of balancing space indoors and out (not knowing surroundings).

Ask your family what they would like to see, not designwise, but plant materialwise - color, texture, fragrance. Even ask your mother-in-law. You have provided some architect's dream, with the bold geometric forms, the bold palms and cycads. How about something warm and fuzzy. Something to rub your hands on as you head to the door. Some color and fragrance beyond the white and palm trunks. How about vines to soften the hard edges of the planters, fill them with ground cover plants so you won't see the mulch in a couple years, add bulbs of all seasons to bring cheer, glossy leaves to brighten your day. Bring nature to your entrance area to warm up the arrival of your mother-in-law. How about saving room for a couple chairs and small table, to sit out and prove that people actually live in this piece of marvelous sculpture, and add the warmth of an outdoor room. Spend some time at the library with books about the architecture of Frank Lloyd Wright. He is the one who introduced the architectural design idea of the outdoor room. Come to think of it, I don't remember ever seeing a garage door in any of the photos. Guess I'll have to take another look.

Congratulations Aaron on finding your "Forever home" & wanting to preserve it's 70's vibe. It does look like a big project to get your teeth into! I would think the black to be a bit strong & tend towards a warmer tone with the brick. Sandstone is also a light stone with yellows, apricots & warm tones. Woodland Grey from the Colorbond range has olive/brown tones which might suit. It depends on the vision you are trying to achieve but it looks like a natural modern style would suit the theme of the house. By that I mean taking cues from nature for colours. Good luck!

I think the task of transforming homes like these is an exciting challenge! If your budget is not huge then timber trimmings and paint can make a huge difference here. You could paint the brick, or better still clad it with weatherboard to soften the house, but if the budget does not allow the whole house to be clad just do the front and go around the corners by about a meter and then paint the bricks at the sides and back to match. You definitely need a verandah across the front, with the steps centred and going straight down to meet the gate - this will transform the facade and is worth spending the money on. If you dont want to change the windows consider framing them with timber to make them look larger and replace the front door with something nicer, luckily your door is centred with same size windows either side. Id suggest replacing the fence with a picket fence and matching gates to hide the concrete driveway and then screen off the long side driveway and camouflage the overhang with a picket gate to match. Paint choices here are really important, it looks like your neighbours homes are beige or grey? Consider painting the house a classic colour such as dusky blue or sage combined with light trimmings to make yours stand out from the surrounding neutral homes (ive done a couple of quick mock-ups below as examples) You need some plants but your front yard is not large so a single, low height feature tree with mulch or pebbles instead of lawn would look wonderful plus a couple of strategically placed pots. Good luck!
