unable to read the correct measurement here's my suggestion for the ensuite and other bathroom but please correct the room measurements so that i can correct any discrepancies

Great to have you see this and reply, thank you so much! AND a massive Happy Birthday to the amazing Siriuskey!! So glad you are having a lovely day, honoured you dropped by on this special day :-D !!

Yes, sorry for not giving context!

The old house is a long narrow ranch house which OkLouise you have shown exactly the old section beautifully in your plan (with furniture!). The new extension being the rectangle with kitchen laundry etc.

The reason for lots of rooms is that we will eventually be turning the whole left side of the house into an SEPARATE apartment for a grandparent ('Sitting' will become kitchen). Also, the front guest room in middle is a therapy room for me for work, so I need the toilet to open to that to avoid clients going into the extension.

The master bedroom/bathroom/wir annex is, therefore, the only part that will change in the extension apart from that.

OkLouise re Master Bed Annexe - I can see this is a good idea in that I wouldn't move change too much, but make better use of the space!

Though I can't move the Master door (towards the passage) as there is an attic entrance with pull down stairs up in the ceiling exactly there.

Sirius I agree that the toilet is unfortunate, but I don't have the budget to move the toilet really or change too many walls - or would definitely widen passage.

So toilet under stairs, can't do, and, let me know what you think... I am putting a gas fireplace UNDER the stairs in the void. Perhaps weird, but I had a Feng Shui consultant go over the plans and it was the only place deemed 'appropriate'. So this will be a transitional space with a mudroom, a fire and a place to read and enjoy the void??

Purpose of space between laundry and stairs: The piano will go against the stairs in the passage entrance area (opp laundry).

Cooktop opposite sink. And the reason for bench not being all the way is that I will make a computer desk in the corner where the hinged door is. (Gotta keep an eye on those kids and what they are watching on the computer!)

Re hinged door to kitchen, I am inclined to agree re nixing the door but as we are doing Binq sliders which are heavy timber-framed sliders I was just concerned about not having a hinged door to duck in and out of easily.

This is my (not metric!) intuitive version of an Master Bedroom annex. Is this at all workable in your view - thanks for considering.

you need to double check your measurements but your bathroom will fit if the measurements are exactly as shown...the bath, twin vanities, toilet are all generous sizes but any changes will affect the entry to the bathroom and encroach on the shower space, the WIW allows 50cm hanging space all around with 1m wide walking space and the dotted line in the hallway shows the original position of the wall which has been moved to allow a more generous hallway

Hi there Tyrian, thank you so much for your lovely birthday wishes, I'am still recovering!!

Still not certain which walls you were having to line up ?, why the walls in the kitchen dining stairs space wouldn't this be better as one space, except of course the stairs which you need to be able to close of so as not to lose all the heat upstairs.

The gas heater under the stairs sounds a bit strange, what happens to the flue and the heat will all end up upstairs? Would the piano be better there.

I would keep the single door opposite the kitchen, what with the appropriately placed kids study desk that door will get plenty of use.

Very impressed with your forward planning to include parents/family members, parents give so much to their kids so it's wonderful to see someone like you planning to give back, full marks cheers

Sorry not to get back immediately! I am so thankful oklouise for the drawing! Amazing! I think the dimensions are correct so would work. Would like to widen the passage but it depends on how much it costs.

Lol Sirius, glad you had a lovely birthday, good for you!

Thanks for the full marks, I am grateful to the senior one as this project would not happen without them, but they also need help so it is definitely in both our interests. And they already are living with us in our little rental - it's a bit stressy so as you can imagine I am keen to move ASAP on the extension.

Re the walls, yes the idea was to align the internal walls with external walls, which are a bit off. The internal idea is new and architect is away so just added with out adjusting.

My partner does not like open plan so much and wanted some relief from noise and smells. He wants half walls with big sliders internally so we can open up or section off.

And I agree the fireplace is weird.. still pondering on that - I will think on your excellent points as the heating issue is kind of problematic..

Partner also wants to keep hinged door if possible so we might just have the sliders made narrower to accommodate.

Thank you for your thoughts!!!! Happy recovery and I appreciate all comments from anyone who has time, thanks it really helps.

1.consider having a hinged door at the end of the sliders..all in one unit and 2. you need to double check the options for the gas heater because the flue needs to come out under the floor (or go through a new upstairs room) and the flue can't come out close to doors or windows so i've included a new space for a heater and hope the Feng Shui consultant will be able to offer some suggestions to counter any negative impacts 3. i don't think that there's enough headroom to have the heater and chairs and a walking path and wall space for coats etc under the stairs but there should be enough for a simpler staircase as well as space for the piano and 4. having an enclosed lounge area makes more wall space for furniture for both dining and living areas and 5. there's enough space to add a little to the length and width of the laundry and pantry and 6. the existing kitchen has very little counter, storage and walking space and my suggestion offers alternative options for the quick access hinged door, IT nook, central island and observation to the rear garden

Oklouise, very interesting take. 1. Could work to add door to frame, but as they are heavy I am not sure, I will check with the company if it is possible. 2. Yes, I don't know about fire under stairs idea, I was thinking that the flu would go up behind the stairs somehow.. also was considering just moving the fire to this wall, a double-sided fireplace would be very lux! (I think maybe that adding a fish tank would negate the impact of the fireplace ;-), I will ask). 3. The mudroom is really important to me as currently we have a pile by the door and plastic hooks that keep breaking! I agree it's not looking big enough. 4. I love that you mention this, thank you!! 5. That is a great point re length of laundry. I guess we were going to put furniture there, an indoor plant etc. but I might even nix that for the computer desk there. Though I beginning to like the idea of a bigger pantry now I look at it. I am having analysis paralysis now.

The writing in the pantry says upright chest freezer/minifridge.

The plan you provide for the master bedroom is super interesting! It's affordable and remains within the walls which I love.

To put the entrance door where you have it is really important though for this design. I don't know how easy it would be to relocate the roof cavity entrance/pull down stairs, but I will ask a builder.

Can't thank you enough oklouise, I am sending your virtual hugs and a bottle of your fave tipple!!!

thankyou for the virtual hugs but unfortunately i don't drink..in the meantime please 1. post a plan of upstairs so i can see how the stairs fit the upstairs rooms..2. gas heater flues have very strict installation requirements and i think an underfloor flue would have the least impact but the heater needs to be planned before you start building to avoid expensive disappointments 3. some heaters have a rear vent rather than very expensive double sided and could have the "fire" in the lounge with a rear vent to heat the mudroom and take up much less space 2. the pantry does have space for the freezer 3. does this modification allow for the position of the pull down stairs??

Hello oklouise I am sorry not to be able to respond more promptly I have been uber busy. Wow I love the plan for the bathroom - thank you!!! But I am really going to have to wait on my master suite and change a few things as I have spoken to a Renovator Friend who has made me aware my budget is a problem.. to the point I am giving the existing house AS IS to my in-law and just focusing on the extension for my family. :-/ for now? Always wanted a Master Suite!!!! The bedroom will have to be my office for now and I will out a door in what would be my future bathroom. (Insert crying emoji)

Reno Friend has suggested get rid of wall separating mud room/ stairs area. She suggests flip entrance to stairs to closer to door (thereby giving opportunity for full windows over west entrance door allowing western sun. Full height wall where stairs end and slider door there to the middle living/dining wall she suggests we keep. Effectively divides the space into 1/3-2/3. I will need a kitchen in my laundry now as I can't access toilet in extension.

Upstairs study will now be my bedroom - so area over void will become my wardrobe.

will study and respond asap but the upstairs measurements don't appear to match downstairs..please post a close up of the extension with the measurements clearly readable??

subject to correct measurements your friend's advice about the stairs would make much better use of all the available space (with or without the wall separating the lounge) and increases the size of all upstairs rooms (including bath and wardrobes) and any of the bedrooms would make a good master bedroom until you can renovate your master suite
