There’s lots of possibilities, but are you envisioning renovation works (like moving walls, redoing bathrooms), or is this just a conceptual rearrangement? If you have a budget for renovation works, what is it? And how old are the kids?

Thank you for your help. The kids are all 5 and under but we are expecting to stay in the house for another 15-20 years so also thinking what could work well as they get older.

In terms of renovation we weren't planning on redoing bathrooms or any major changes but were considering whether shifting internal walls / windows within the existing floorplan might give us a better use of space rather than just using the media room as it is for a third bedroom. If we had a blank page to design the house ourselves we would have had 3 kids bedrooms in a wing around the bathroom so I suppose I wondered whether that kind of change would be a possibility and how much it would cost.

Budget - something that we would consider doing now if up to $15k or in a few years time if more like $30-50k.

For a budget of $15k. I would use the office room. At 5.6 wide, I would build a wall across the room. 3.6m for bedroom, 2.metres for office. (Less wall width) Both rooms have a window. And the outside store on bedroom side could be changed to a BIR on bedroom side. Install new doorways into each new room. the office size will still be a decent room for a office. You said this is a brick home, are the internal walls brick? The other option is to reduce second minor bedroom next to media room and create a hallway, and new doorway into new bedroom created in part of media room. Again building a wall to create an office near the kitchen area. But, I do not think reducing a bedroom size is beneficial.

As a parent of four, I know how the use of your home changes as your kids get bigger. I would be hesitant to divide up your current office, as it seems like it might make a nice second sitting area that you could retreat to when kids are older and watching TV / hanging out in the main living / dining. You could put the home office part behind doors if you wanted to hide the office mess. Depending on accurate measurements, you could divide up Bed 3 and Media into two good sized bedrooms. I would try to make the three kids bedrooms as even as possible in floor size to avoid complaints when they’re older! This would cost more than your current budget, but in the mean time I would use the current office as the third kids bedroom, and put your home office space in the Media room.

Thank you so much for these great suggestions!

I also thought the current office could be a great second living area as the kids get older so I am reluctant to split it even though as dreamer shows it would split into a good bedroom and office without spending as much. I think we will investigate the more expensive option dividing up Bed 3 and the media room down the track, I hadn't thought of splitting the rooms that way but think it could work really well and still keep the kids bedrooms all a good size. Thank you, I really appreciate the ideas and time.

Great ideas above, I have drawn up the rooms in question, some dimensions are missing plus the size of the powder room and windows in that area. I have shown the new bedrooms as the front room @ 4.3 and not 4.4.. I have included beds to show you the available space. As you can see by the drawings the Media Room can be split but if the bedroom is to match Bed 2 there could be an issue with a window for the Study/WIP because of the Powder room. The option could be to make Bed 4 and the study(Bed 5) the same size to become 2 smaller bedrooms while the kids a little to share or use that Bed 5 as a play room?

You could use either room. Look at the natural light in each space for their intended use. My first thought is to divide office as this has the natural light for office space.

Thank you siriuskey for the much better drawings than mine! I have measured up the dimensions along the external wall in Bed 3 and the media room - the powder room is smaller than on your plan so there should be enough space to fit in the window along that wall.

Your drawing is excellent, this is a basic idea not having all room dimensions, I have added your adjusted dimensions with the red broken lines showing the sizes you quoted. As it shows, that if bed 4 was made wider you would lose a window into what could be the playroom study 5th bedroom, this room could have an opening skylight .for the first two uses

I like the idea of the parents retreat and possibly opening up from the master into that. Do you both work from home full time
