Hi Em, I'm not suggesting that you have to start again, only that it may provide you with a better outcome than trying to work with what you already have. By starting with a blank canvas, new possibilities arise. I agree with most of Amelias comments and I'm not interested in getting further involved beyond my general comments. Good passive solar design is now a fundamental of good design practice these days and that was not evident in the single level plan you published. It's not just about northern sun, which can be excluded in summer by a simple roof overhang, it's also about excluding the extremes of the sun from the east and primarily from the west. So you can see that your games room will suffer the hot afternoon sun in summer as it had a lot of glazing facing the western sun. Protect that elevation with a blank wall to exclude the sun or at least restrict the glazing to the west by incorporating either slot windows or high level windows that gain protection with screens or roof overhangs. Open up the games room with glazing to its north and east. Create a small courtyard perhaps with some luscious landscaping or water feature that works for both the games room and the living room. Returning the glazing will allow for large glass doors to slide back into pocket walls bringing the garden into the home and blurring the line between home and garden, thus making it feel bigger. By incorporating more glazing to the north you will visually "widen" your home, making it feel less restricted because the room boundary will visually move to the fence line while at the same time providing better solar access during the winter months, which helps warm the home and maintain a year round comfort level. Sydney has a mild winter compared to southern Australia. Take a look at some of the homes designed for narrow east facing sites in the northern beaches of Sydney or on the far north coast in places such as Salt. They all have similar siting as you have. They all offer mass glazing to the North and open their living up to the north and the east with pools, terraces and outdoor living areas etc. Don't be scared of experimenting with simple shapes at first. Just pencil in where you want the various functions to be placed and make sure that they work together. Move them around until you think you have the relationship right and go from there. A well planned house is a dream to live in. A poorly designed house will remind you every day that there is something wrong. So invest well in the design because it will pay dividends. Sure, seek help but be cautious because the help can be confusing which is why I have tried to take a general approach to it all rather than squawk over this or that. It's your home and you have to live in it, not me, not AU or OK or anyone else. Keep it simple and have it function like a well oiled machine and you will love it.

I suggest printing off your plan and drawing your furniture on to scale. Allowing for at least a metre between things like the island and table, sofa etc , it will be hard to fit everything in. The room has a lot of doorways etc that need access space. You could perhaps have the dining table in front of the island and then a couch facing the island but is this enough seating? The other thing to consider is what dining seats you have and how much space they take up, both in and out from the table.

Appreciate the thoughts and this may be a solid option elsewhere in the country but in my circumstances I don't plan to be moving from this property any time before the kids are 18. It is located in Sydney's inner west, and in a specific high school catchment I plan to take advantage of when the kids are older. Stamp duty to buy the property was close to $100k and if moving out even in ten years to a larger property; that averages $10k a year spent on stamp duty. I know 115m2 internal is tight, as is the fixed layout due to existing bedroom walls, ceiling heights, wet areas, and the like - but there has to be a way to make this work... I have read that 4 bedroom apartments should be 102m2 or bigger. I am willing to make compromises where possible but I really want to create that extra separate room "Multi-purpose room" which can double as a study/work area/kids play area/media room/ad-hoc sleeping accommodation". Paul Di Stefano: I don't think these changes essentially equate to 'rearranging a sock drawer' - this is my PPOR so I am not too concerned what other buyers want or resale value if I plan to hold the property for 10-20 years +... (any trends we design for now may well be outdated by then anyway). Many buyers highly value indoor-outdoor integration. By moving the kitchen to centre, it opens up the rear and creates indoor living->outdoor living link. If I get IKEA flatpack kitchen and DIY as much as possible - have a friend reroute the water/drainage/+his licenced electrical friend...hopefully this work would cost sub-$20k. Adding the sliding door to rear is $2.5k. Ensuite, bathroom and laundry I believe I can fitout for $10-15k all up- let's say 15k (again, tiling, raise flooring, showers/fixtures/flat pack laudnry cabinetry install all done in-house without tradies). The only thing I really need professionals for is to move the gas line in kitchen, BIR installs, stone benchtop, and maybe a few adhoc wall demo/construction/doorway moving - lets call that 10k. All up ballpark that is 47.5k? Sirius- If I go with your style plan then I lose the potential 4th bed space and have no where for relatives to stay, babysitter, nanny; etc :( Maybe it is a possibility that the main living space be used for lounge room and kitchen, we can always put dining table in the Multi-purpose room, then when that room is needed for sleeping accommodation, the dining table be moved to the side and kids can eat dinner on island bench bar; lounge or outside table... ? those doors to each side of the fireplace as you suggest - this space is very cramped outside (2.45m width) and potentially would be used to store trailer or garden shed, there is an old terrace built on zero-boundary there and they have a DA to go 2 storeys; which will shadow the whole area. This is why I planned to make the rear south corner a raised deck and try to channel house activity leading out the existing glass french door to that deck, or the rear sliding door. See photo-(my house is on the left, terrace zero boundary on right, and front on is a wooden dividing fence which on the opposite side is the driveway/1 car park and front street.

Update on this. We have decided to keep upstairs unchanged in terms of layout. We will live in the house for a period before making any layout changes upstairs - 2 Bedrooms will be for our girls, while our son will sleep downstairs in the living room (now bedroom) as this was seldom going to be used. Now we are looking at the kitchen design - photos attached of current kitchen which will be completely refreshed along with the tiling in the kitchen / living area. Looking for any ideas on how to best update the kitchen - notice under the stair case is not currently being utilised but we would like to perhaps have the fridge or pantry under the stairs to include this dead space. From the kitchen window to the stair case is 4950mm x 3200mm approximately depth of the current kitchen. The stair case hangs into the kitchen around 750-800mm. Wondering if it would look silly to have perhaps the fridge built here and this cabinetry would sit proud of the bench space next to it, but we could also install deeper bench space to balance the look... We are planning to have the eye-saw built in fridge space currently in the kitchen removed altogether.
