As others have said, it depends on your environment and view. If the house is located in a particularly hostile environment (e.g. west coast Tasmania, central Australian desert) or experiences wild swings between the seasons (e.g. Snowy Mountains) then windows are your friend. In temperate / sub tropical areas like Brisbane then verandahs are the way to go. Windows can have great thermal properties IF they're double glazed which has better insulation properties than say walls in a QLDer house with a timber stud frame sandwiched between weatherboards and VJs. It also depends on the orientation of the house.

yes oklouise, I hear all that - absolutely yes it's all about clients understanding/working out properly what they need.........and it's great to be able to seek comments/thoughts on Houzz from a broad range of backgrounds/experiences......the issue though is when it gets into territory where (from my perspective) clearly experience and professional skill will help resolve the problem most effectively (such as on this particular one) that it's therefore appropriate to suggest this the advised way to go.......I suppose I see frequently here capacity for designers to be able to "cut to the chase" most effectively, but of course this needs to be done in a manner underpinned by a thorough understanding and establishment of what the client needs in context, and yes very often the client will require more time to work this all through.........I however still see our role as relevant in that part of the process though, and not necessarily having to "wait" for that to happen, because ultimately as professionals in this position (i believe) have a responsibility (as part of our role as a consultant) to educate people appropriately and thoroughly so they can develop the skills to be able to consolidate their decision-making most appropriately for themselves and the project - by the end of the journey, I find my clients are rather quite the experts!..........this however involves a collaborative approach, egos are shelved and an intimate working relationship, which is very different from the approach (that some designers work to) which is essentially selling a "product" or particular end result, rather than a service....significant difference, and again, horses for courses ;)

as always depends on budget but i'm wondering if a steep gable roof at right angles to the main roof with a raked ceiling and solar roof vents would allow better ventilation with enough headroom for a ceiling fan and adding some panels of transluscent insulated polycarbonate closer to the house would help avoid the overshading ...we've used a diy double layered polycarbonate and there are insulating products available eg Arcpanel and, to improve light inside the house (or under a dark alfresco roof) consider Solar Skylights (not hole in the roof) like Arcol or illume brand that we use with excellent results for a modest investment, DIY installation and no risk of roof leaks

Hey! Figuring out the layout can be a bit tricky, but don't worry, I've been there too. It's all about finding what works best for you and your lifestyle. Personally, I'm a fan of open floor plans because they create a spacious and connected vibe. It's great for entertaining and keeping an eye on things, especially if you have little ones. As for the bedrooms, it depends on your needs. If you're thinking of a home office or a guest room, that's always handy. For those planning to purchase a condo in the near future, I recommend looking at the options that Hillock Green has to offer. They are considered to be one of the best real estate developers.
