I think you need to show the house. Hard to tell just from seeing one room.
IMO

You still have 2 Living , 2 dining areas -- I suspect we can all make suggestions , BUT a lot more info , such as ages and lifestyles of people living there , if that makes much sense ?

Some of the bedrooms look on the small size , but even ignoring that , there are so many combinations . The problem is guessing whether you want to stay , or doing it up to sell ; whether you need 5 bedrooms , whether you would consider removing or adding some walls , etc .

We plan to live there - 2 adults aged 60 with small grandchildren and guests staying occasionally. Our thought was to convert bedroom 4 and 5 and adjacent bathroom into Master bedroom with en-suite and walk in wardrobe. The living space near there would be a bedroom for grandchildren. Bedroom 2 would be my home office and bedroom 1 for adult guests. Just this old kitchen space we are pondering what to do with.

Agree with big reader - would convert kitchen into laundry. Does the external door nearby lead to backyard/close to clothes line?

Laundry and include your wine fridge . You can make and attractive laundry that hides the mess and allows you to use space as part of entertaining zone when needed.

So Kylie, If I understand you correctly your thinking: east side: office, guest master with ensuite, kit, living/din and lovely deck. West side: entry, sitting/bedroom, grandies bedroom, space........ robe in little bedroom, master with skinny bathroom your ensuite. It leaves the center bathroom as pwd room for guests not staying tho it would make a great pantry!! And the space: I think moving the laundry there is the best idea: All I can see is a l'dry in a cupboard in the kitchen for a 5 bedroom home! Another suggestion: east side: office, guest bedroom with ensuite, kit, liv/din/deck. West side: bed, leave as living room, laundry, grandies bedroom with robe down center backing the din/living that is staying. So with a mirror door or two and some width you could walk past your robe on your right as you go to your bedroom &/or ensuite. That way kiddies are near you, the space in center of house is used, living room is still close by the other living area and you will have a wonderful laundry for a FIVE 5 bedroom house with 2 living rooms too. The space is ideal at 2.2 wide: it needs two straight lines of benching. so close off the db sld doors, leave ext door and put a cav sl opposite it into hall by living room. The robe to the right as long as you need and wine store backing laundry (Just so you can grab a bottle on your way to bed!! ha ha) But it would also be near kitchen and dining too... Does that make sense? Hope so or I can draw it for you..... Great idea: zoned north for you 2 to live in most of the time but south for when you have guests...... Cheers Margot

Margot, this is a very generous response and thank you! Nice idea to grab a bottle of wine on the way to bed! Are you in the design business and in Sydney? I will need contacts should we go ahead. I think I follow your suggestions but will take a closer look and go through slowly soon. Too much to ask for you to draw but kind that you offered.

One thing I am not keen on about Houzz is that I do not think I can contact you privately. But very happy to assist further... You will need to look me up and find my mob number. I am an arch draftee, in the design business but Melb and getting used to using tech to show plans etc. It doesn't beat a personal meeting by half but a good chat goes a long way!! Chat, Pictures, 25 questions and ideas of how your function day to day and under "Normal times". THEN I can ensure the home meets your needs properly! Look forward to it... Cheers Margot

Thank you Margot!

Hi again Margot? Not sure if you will get this after so many months. My daughte is about to move out so we are getting more serious about wat to do on the west side. I couldn't quite follow the suggestion you gave. If it is easy to post a quick sketch would that be ok? I can also look you up and privately find out what you charge but Melobourne may not work? (as I am in Sydney). Kind regards, Kylie

Kylie, I am so sorry I did not get a notification that this msg was here.... Tech... Pfff Grr!! Would you like to call me if you are still having trouble with your plan.... anytime.... Sorry again... I hope I can assist further to get house right for you... Cheers Margot

Still working on it. I looked you up and your in Victoria? I am in Sydney.

Yes Kylie I'm in Victoria, And although I am not very good with tech I do work a phone and email very well!! So happy to go that way for you..... :)
