Hi Adelaide again - been giving more thought to my suggestions and they are not going to work. For some reason I just can't get my head around metric sized rooms, I have to convert back to the old imperial. So assuming you are going to build up the alfresco area to make it a walk out from the house, look at taking that right across the rear of the house. With the master bedroom I was looking at walking into a hallway with a walk-in wardrobe opening off it but you will basically want the whole 3rd bedroom to achieve a decent sized wardrobe and give you maximum storage. I'd have the ensuite where the void area is, which basically leaves you the laundry for the bedroom - way to small. However if you were to extend the bedroom across the alfresco area, this would give a great sized room, with large windows looking across the back garden and doors opening out to the alfresco area. I'd then extend the house and the alfresco area to the end of the Activity room, slide the family room to that end and put the laundry in at the void end, which could be accessed from the outside or from the family room, whatever suits. This also has the advantage of keeping all your plumbing together except for the kitchen. Don't think about excavating, it can cause massive water problems. No matter how much you might add drainage, or seal the structure, there always seems to be those on in a hundred year events that can cause unexpected flooding. Water problems have to be the worst nightmare.

Well, it has been a long (and sometimes painful) process but we are nearly at the end of the extension/renovation. We ended up going with a building designer (Dalecki Design) who made a few changes we really hadn't considered (including moving the existing bathroom) which may have cost slightly more but completely changed and improved the master bedroom space. Without the pool it will be close to the upper end of our original budget but still within what we were hoping for so fairly happy with that. Overall the new living area is amazing and filled with light compared to the old design. Will throw in some photo updates once we have finally converted the front yard from a sand pit and finished off the driveway, garage door and fencing.

Hi Do you need four bedrooms? If not, turn main bedroom into a kids room. Turn the lounge into main bedroom with en-suite, knock down the wall between the kitchen and the bedroom at the back of the house and then create one big open plan kitchen living dining across the back of the house. I envisage you would need to knock out the back wall of the house and add some square footage to get the space you would desire. You could also build a patio across the back with stacking sliding doors to create a beautiful indoor/outdoor living space that overlooks the pool. Good luck!!

Thanks Jeanne and Janet :) My kitchen is certainly earning its keep during lockdown here in Melbourne - excessive amounts of cooking and baking happening ;) The renovation was great practice for lockdown, with three of us confined to bedrooms and a makeshift kitchen for a few months while the house was dismantled around us.
