What do you want in the ensuite? Double vanity? Double shower? Bath? If so, what kind of bath? A separate / private toilet? I think the answers to those questions will direct you to what shape room will best meet your requirements. But, in general, a long, narrow design seems to be the most appropriate, with the shower at one end, sink/s in the middle and toilet at the other end.

If you search DIY banquette on Pintrest you’ll see instructions and measurements. Most are in inches but you can convert them. Could you measure the seat height of the chairs you are using with the table (you need the table first) subtract the cushion height and that will give you the bench height. It does depend on the height and weight of those that will be using it the most, to get the best fit.

1.4 x 1.4 is pretty pokey , and no , I suspect an 820 door will be too wide unless you swing it outwards , which is just weird . If it swings inwards , even if it at 90 degrees to the toilet itself , there will be almost no room for a person , a WC and the door 'swing' . Most doors are at the end of the room , the WC at the other end , and that will make it even worse -- if the WC protrudes 50cm from the wall , and your door is 820 , you have 8cm in which to stand ! Setting the WC 'offcentre , the door off-centre the other way gives a bit more space , but add a basin and you have an obstacle course to negotiate . Is there any way you can take the length to around 1.8-2 metres ? A width of 1.2 works , 1.4 might sound better , but with only 1.4 of length you are pretty much stuffed . .

Thanks everyone for the helpful advice. I assumed my layout would be similar to that of other Californian Bungalows of the same period. It is helpful to learn my layout is reasonably uncommon and I am probably looking for inspiration in the wrong places. It sounds like Dr Retro House Calls and JRED are correct in steering me towards an interior designer. I hadn’t considered that option as I thought I would need a large budget for furniture and décor if going down that path. I’ll give Bigreader’s suggestion a go first and use scaled cut-outs of furniture to play around with furniture placement. If I still need guidance after that, I will look into interior design services. I initially shared your thoughts – Melt in ACT - and was thinking about turning the laundry space into a large bathroom and then moving the laundry to the small bathroom. Ultimately it was going to be too expensive… and seeing as I have young boys who get every item of clothing they wear dirty within 5 minutes of putting it on, it will be a bit of a luxury to have a big laundry. It's an idea I might revisit in the future though. Oklouise, I love all your ideas and suggestions and am really grateful for the time you’ve taken to respond. The floorplan you’ve put together is super helpful. I was bummed about the lack of space for an entry set down area and would have never thought about moving the bedroom door. I will definitely look into that. Good memory siriuskey- I did previously post about this house and I received a couple of good suggestions (including advice from you) around maximising kitchen bench space with a kitchen island and adding a storage wall near the small living spaces. I felt the advice sought in this post is sufficiently different to justify asking a new question about whether there are resources I may not be aware of and if people have ideas about the floor plan as a whole, including spaces I had not previously asked about. I’ve got lots of new ideas and really appreciate everyone taking the time to share their advice. This is a great forum/ community!
