always good to please your husband and you'll have a better chance of achieving a good result together....cost will depend too much on the reality of the site to guestimate...we always begin by consulting a builder to check the existing building to see what's possible structurally, check with Council to see what's legal and then you'll need formal plans drawn up so you can collect quotes but i'd be inclined to ask about the whole project as you may have a better chance of attracting an experienced custom builder for a bigger job than just the small extension (even if you negotiate to have the work done in stages ...best of luck

Kate: - I like the idea of a door at both ends of the new central bedroom doorway - maybe some kind of thin sliding door or a foldable shutter door might be best? - house can’t be knocked down/rebuilt due to location in a heritage conservation area OkLouise: - thanks again for doing this - I’ve loved all of your updates, they are so well thought out and hope to incorporate them all into the build - will send you a token of appreciation when the build is finished! - we have already been thinking about whether to rotate the kitchen island 90 degrees as you have drawn - i think it might look weird? but i’m not sure - theres a lot for us to process with your new updates so we'll need to spend some time thinking about them! - i’m resistant to reducing the size of study 2 as that’s the most important room for me as i will spend a lot of time there and it is doubling as a work productivity office/man cave so really want that room to be fantastic! - i thought the laundry chute was above the laundry but will need to ask the architect Siriuskey - I also think there may be too many bathrooms in the house - due to the good location of the property i think it is hard (within reason) to overcapitalise on the property so believe it will grow well in value in the long run so would rather overdo it than underdo it - FWIW the other houses in the street/adjacent streets are kind of similar to our proposed plan so its not out of keeping with the area - am still wondering about combining the downstairs powder room/adjacent en suite into one big bathroom for a bath - variable number of family members staying but 4 to 11 over 3 generations at various times of the year - the plan for the mudroom is for it to be the entrance into the house that we use most so it can also act as a cloak room too so that’s why its not near the laundry - i don’t want a lift in the house as it seems unnecessary for our needs and fi we ever ended up in a situation where we needed a lift we would just sell and downsize Dreamer: - i think we (parents) might end up living downstairs when the kids get older/noisier - they are in primary school currently Pleased to Bijou design - point taken about number of bathrooms - i don’t really have a good answer Paul Di Stafano & Dr Retro - i can sense and empathise with your professional frustrations :) - thanks for the good luck wishes, I agree we’ll need it - fortunately I’m a lifelong/relentless optimist and things always seem to work out ok in the end (and if they don’t, I’ll take it as a positive learning experience) - thanks for the insights into dodgy busy practice business models mummagabz - thanks for comment about small robes - will look into making them larger

We have the same layout as you in our 90s spec built home. We have Bunnings type cavity sliders so I imagine ours are about as cheap as you can get. They are awful - they are noisy when they slide so if one of us gets up in the night for the bathroom, we have to open the door in slow motion so as not to wake the other one up! We have them on our other wet rooms through the house and I find them not too bad acoustically but they don't screen anything in the ensuite. I would not recommend them at all. As for whether to have 1 or 2 doors, the only time I close the WIR door is when I am at my wits end haha! It's a great space for a private phone conversation but I really couldn't be bothered closing the door any other time

I just think if everything is jammed in tight it won't seem relaxing and you won't use it. When you consider what you use every day (vanities and shower) I wouldn't compromise them for a maybe-once-a-week-if-most dust catcher like a bath unless you had heaps of space.
