I would be more worried about the great view of my partner using the toilet when I am in bed. I think your main issue is an oversized ensuite which has compromised your WIR size. Make sure that your master is big enough for a king size bed with side tables either side, and give your ensuite some privacy from the bedroom. So many people really hate the 5-star hotel fashion of opening up the ensuite to a view of the bedroom. It isn't sexy after your honeymoon. Back to the drawing board, or consider enagaging a professional designer to get the proportions of these rooms right for the scale of the rest of your house.

This wasn't your question, but looking at a possible boxed out window in the open plan kitchen dining living it shows just how limited you space is. The following 3D overview shows a boxed out window seat. I have run the kitchen along the same wall as the new window, The Island is 2m x 900 with 1m between the wall base cabinets and the island and 1m between the Island and the wall where your plan shows cabinets. If you have/had cabinets along the other wall as shown on your floor plan they will be 600 deep this would make the island 1400 x 900 which is small. Has your kitchen been renovated and were you considering that, if not. Looking at the overall size of your open plan area I would be considering 1 or 2 large stacker doors to open up to the rear alfresco, that's what I would do but you need to choose what will work for you PS I think that the boxed out window at the front of the house is a lovely idea but possibly not right when it faces West.

Thanks @oklouise, @siriuskey. I know I really really need to get up in the roof (or more likely get someone else to get up there, it's a small access hole and a long way off the ground and I'm not great at either of those things with a ladder). If I'm right about a max ~3m height in existing roof space we could fit ~3-3.5m wide room essentially above the hallway of original house and meet minimum heights (I think....). And then hopefully a little wider under an extended roofline to the back, without it being a full/boxy second storey extension. Here is a super rough sketch of the current layout of the house. The dotted orange lines are drawing over existing roofline when I overlay a screenshot from google maps, so not 100%. I don't have a proper house plan, will need to get something drawn up. It pretty much fills the block width (~0.5m from wall to fence each side), but we have heaps of backyard to extend into (`18m from current back of house to back fence), but do plan to eventually add a separate garage accessed from back lane and want to keep a big backyard. No important view to chase, but looking directly south is over green space/park, every other direction is pretty suburban. If the roof conversion is possible, I think I want to convert the small bedroom 3 into a family bathroom, kitchen into a 3rd bedroom, split the dining in half and make that into a study off the lounge. Then push the whole back wall out probably 2.5-3ish metres and in that open space, fit a powder room, staircase, laundry/mudroom with external access, living/dining/kitchen. Possibly fit a scullery into the other half of the current dining? And put a covered deck off the back. This is the real design dilemma I guess, where exactly do the stairs go (against wall shared with lounge?), and if no roof conversion, then it's either raise up full storey (still need to work out where stairs go) or work out how to add a master suite to single storey extension. I'm really struggling with getting that to work.

Hi Anna, By now you have likely conquered your space and are happily on to other aspects of your fantastic home. I only came across your post last night and started thinking what would I do if this were my apartment? I would lean into the what is. If it's a dark corner, use the darkness. You know 'use the force Luke'. The contrast with the light-coloured neutral sofa a medium to dark colour for the wall from the entrance will make the space sharper. The sofa will make it look 'light' even though it's not. I wouldn't go with matching pillows to the wall, but I love the cactus at the beginning of the runner which when you are seated on the couch would be a visual break from the entry and bathroom door but no width to touch you as you walk past. I would remove one of the mirrors along that wall and hang the other horizontally about 20 cm above the back of the couch starting from the corner. This way, when seated in the armchair, you are not looking at yourself. I would hang the second mirror on the back of the front door so you can check yourself one last time before leaving, or when coming out of the bathroom. In this example, they have not used a rug to define the living space, but a runner to define the 'corridor' past it, which in your room would be past the bedroom. I would have the armchair just off the runner deeper than the kitchen bench. I would also not put anything in the 'corner nearest the sink as that would be the doorway to the living area and also when you are seated give you a clear sight line to the balcony. For the wall with the aircon, I would put a dramatic piece of art that has the same total volume as the mirror but is square or a fatter rectangle hung vertically so that it sits in the middle of the space between your knees when seated on the couch and your knees if seated on the armchair. That is in the 'coffee table' area whether you have any tables. I started the search with my favourite colour for the wall and then searched graphics for the artwork. But really you should have the art to best match the colour on the wall to one of the lesser dark shades in the art. You can get art made from any print relatively cheaply at Officeworks and use an IKEA frame. Or choose from art printing sites that print to stretched canvas, like this one with postage would be around $300. Hang the art so that the middle of the picture is 150cm above the floor. If you did want a rug to define the space, instead of the corridor past it like in my example, I would choose a single colour that was noticeably darker than the sofa in a shade from the floor and possibly even slightly darker than the floor. Darker than the floors would make the floor look lighter (if that is preferable). You can have any rug cut and edged to any size, including having a rug made from a new length of carpet at all carpet shops. And if this was my place and that was my desk, I would set up in the kitchen facing the balcony to the right of the sliding door. After years of working from home that sense of being on top of the world appeals to me. Thank you for the opportunity to fantasise about living in your space. I hope you are super happy there.
