I really like the suggestion Modern feature walls. Combined with some greenery inside and out as suggested by chookchook2 , you can start to soften the 'boxy' look of the space which is now reinforced by the line shape and form of the couch you introduced in the updated image. If it is a breakout or meeting room could I suggest, budget permitting, some form of window treatment. Some simple and relatively cheap e-screens would add a degree of privacy, but more importantly remove potentially annoying distractions from outside; important if you are using the room both for work that requires concentration' .. or alternatively, impromptu meetings with others that may be held in the room. I do like the green, but the photo projects a rather drab uninteresting interior despite your efforts thus far.(imho). I think making a call to Modern feature walls should be on your call list. Something has to be done with that ceiling which I find not only distracting but is actively working against your attempts at creating a really inviting space that people will want to break into. I can a hint of a table off to the right in front of the window. The best breakout spaces I've used have the facility to informally and casually sit across a table with sufficient desk or table space to spread drawings, images and presentation ideas. .. It just doesn't work as well if you and a colleague(s) are forced to sit or stand along one side of a table with the yard providing tempting distractions when the focus should be on communication and collaboration. Mounting the TV and raising it would open the room up further and likely break up the 'box-iness' further. .. A bit beyond my field (Window Treatments) ... but you did ask. lol.

Thanks for all your entries. And those are some marvellous photos of your own spaces being changed. Our congratulations to @how2girl who was randomly selected as the winner of Darren Palmer's book! We will be in contact and send this book out to you very soon. Stay tuned for more contests in the near future. HouzzAU Team

You are most welcome, I have always said that I haven't been put on this earth to "Hug" toilets, so I'am wondering who is going to clean all of these Bathrooms. Our two kids a boy and a girl had the upstairs "apartment" which they and all their friends loved. I have added a timber stair case for fun, there's plenty of space but you will need to decide what you want to do in the attic and place the stairs to open up into a tall space. I have also turned one of the ensuites into a powder room. Your Jacaranda's only drop once a year!, you used to be able to trim them by 25% each year, you would need to check with your council, we were on the lower North Shore, I think you should consider the patio side of the house and make better use of that, is the front deck something you plan on adding because of aspect, and plant some tall growing hedge ready for the apartments. Our kids Attic desk/study space over looked our pool in the rear garden. With respect to using the formal rooms for bedrooms, you will find that once you have your large family/alfresco and the kids have their upstairs space if you still feel you need it, it would make a great office. You spend most of the time there only using only using the front room in the evening for watching movies etc. I have had another play with my floor plan, I think if your wife sees this you may be in trouble, it's a Master Suite, the free standing bath in the window alcove with white timber shutters for sun and privacy control..... Iam' adding a couple of photos of our old Federation which wasn't protected, when we sold it the new owners removed all of the Fret work & posts replacing them with simple timber posts. The front rooms which we didn't use very much once we opened up the rear rooms into a family area. The room with the Bay window had a Baby grand sitting there, we sold the piano before we took the photo. Cheers

As an architect, I have previously been taught that creating a sustainable home is about designing it so that living in it lowers energy and water use. This is achieved through designing for orientation, using thermal mass and specifying fixtures and finishes that are low impact, reuse water on site, etc. However, the latest research is showing that this is not enough to impact the rate of climate change. And that what we build from needs to be considered in order to make a dent. This is because the timeframe required to see the benefits of sustainable living in a home, is a longer play than the upfront construction from low tox, low energy, minimal footprint materials and methodologies. It has to be a two-pronged approach. Choose materials and products, and constructing efficiently with low energy and low waste. Having carbon neutral homes. And designing homes that over the long term, are low in energy and water consumption, and support the health and well-being of the occupants. A project was established in mid 2017, called “The Building Code Energy Performance Trajectory Project”. It involved the Sustainable Built Environment Council and ClimateWorks Australia, and is described as an industry-led initiative seeking improvements to energy requirements in the National Construction Code. The report was released recently, and what was amazing in this report was to read that 58% of Australia’s buildings in 2050, will be built after 2019 … which means that there’s huge potential to impact their performance and the environment through better energy requirements. And these energy requirements have not been rigorously updated since 2010, despite electricity prices having doubled over that time. Detached housing will comprise 64% of the new construction between 2019 and 2050. So every homeowner has the opportunity to seriously change the landscape of energy use and efficiency in our country. There’s some sectors of the industry really pushing back against this … largely because they believe it will dramatically dent their profit margins to have to build houses with higher star ratings. Australian homes, on average, perform very poorly, and our expectations are super low. Steve Baczek, an American architect, said something about American houses that I think sums it up for Australia as well ... “It’s not that High-Performance Houses cost too much; it’s that our idea of a fairly priced home is based on a history of building houses to meet embarrassingly low performance benchmarks. Clients don’t realise the difference between built to code vs built to last”.
