My parents have a covered south facing alfresco in Perth. It's great in summer. In winter, they use a paved and pergolaed (with deciduous vines) area further from the house that gets full sun. Consider losing the bay windows. They will be unbearable in summer. Or push the eaves out, or plant some deciduous trees in the front. I would shift the rumpus room to where the laundry is. Give it a view. Also, it's probably where you'll end up sitting on hot summer days, as your formal lounge will still get a lot of heat. Consider shifting the master to the righthand side of the plan. You could get a lovely triple aspect (north, east and south) bedroom. You could have double doors that open onto a private seating area too. Put the laundry where the master is.

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.

Do you have to use the smaller front boundary for the garage? Is the noisy living space going to work with all bedrooms coming off this space? If the garage went to the south and can it be on the boundary in Sydney, that would leave the middle for bedrooms and the northern aspect for living, as most Australian houses benefit from northern light. The front setbacks would make an ideal outdoor space which high fences or high shrubs if not allowed high fences, if on a busy road most councils allow you to have sound barriers, leaving the entry to the house to come in off the long boundary, which you can make more of a feature. You have a corner block which is always a bonus. The beds will then have a quite zone, the living can have that northern end and cars can be pushed to boundary. Always look at the site before you look at plans. Always make sure the living aspect overrides the plans. Always make sure that living in a space overrides the plans, always.

Wow, this is pretty spot on! What a lovely frontage.
