my 2 bobs worth. as someone who works with the elderly-the en-suite for your MIL is still not right. if she ever needs walking assistance,especially with a frame, getting past that door into the en-suite will be a nightmare. swap the vanity position for the shower. ensure there is no step-down into the shower area, and ditch the shower screen for a curtain. will make access much easier. especially if she ever needs assistance showering..it will be virtually impossible, and dangerous, with your current design. thinking long term..MIL will not always be there with you, so presumably you and your hubby will at some point end up in the master bedroom? consider the long terms implications of this-no good building something that suits her now, but would need major modification to suit your needs later. I would actually do away with the WIR at this time. Plan to add it later, if you would want it for yourself, but i would just use free standing furniture for her-no doubt she probably has her own, so it would be nice to have some of her own furnishings when she moves in with you - to make it feel more like her home. it will free up some floor space, and make access to the ensuite easier, without having to turn corners. I would also do away with the extended passage into the master. Take that door back in line with the other bedroom. Currently, it adds nothing, and may well limit your furniture placement for your family room, as the walkway will need to go around it. i have issue with the 2 person shower and double vanity in the same room. s the kids get older, they /you probably wont be comfortable using the room when you are showering, so mornings will be slowed down. Have you considered a 3 way bathroom/toilet/vanity area? We had this in our house, and it was the best decision ever. The shower and bath were in one room, with a separate toilet, and then a double vanity which opened to the passage. Everyone could use everything at the same time, without encroaching on each others privacy. Not sure about your state -but here, the toilet door would have to open out-if someone collapses in the powder room, you would not be able to get in with the door opening in, as they would be blocking the door. I do empathize with your dilemmas. We have spent 7 years planning an extension and remodel, then 2 years (!!!) working on the design with an architect, going backwards and forwards, and then the last 12 months nearly, changing and fine-tuning along the way as things were being built. It is not easy, but worth it. Having said that, you are unlikely to ever get it perfect, as your needs will change, your likes/dislikes will vary, and you will see other peoples homes and go "why didn't we do that". (Now if only i could take that on board myself, LOL)

Perhaps, not strictly canopy style would work better. Qasair can do custom design, if there is not thing that would fit your need already on the market.

I'm still concerned that the covered alfresco area is located to the NE, it will block much of your winter sunshine from entering your living areas, making your home colder in winter. Personally, I'd try to locate your alfresco o the eastern side of your living areas (& somehow moving the master further SE). However, if you are going to stick with your current alfresco location, I'd recommend you change from a hipped roof alfresco, to a gable roof alfresco. If you make it an opened gable, & have a cathedral ceiling you'll end up with quite a bit more winter sunshine entering your house. Similar to the images below.

It seems (the design/layout) of the building form is progressively getting bitsy and tight ( like in a typical volume build plan) in the main living/kitchen/dining/alfresco area rather than being elegantly resolved with the flexibility potential layout usually exemplified in a custom home .......what is going through my mind is what exactly is the function of the external space to the west which is not at all connected with the internal.....I'd be considering configuring the ground floor better to maximise/exploit the northern aspect...It would simplify the whole thing, be more efficient and less block-like with building chunks cut-out/doglegged just to suit a table or whatever..........It's like the requirements are being somewhat forced within a particular set building shape rather than designing it so it all flows more naturally/balanced and is more elegantly linked and maximises the available land/space/aspect...form (should!) follow(s) function.........may I also comment that perhaps some care/caution/discretion should be taken when uploading documents clearly associated with a particular designer on forums (for public critique/comment!) ;)
