Hey Sally, This is from the ‘Thermal Mass in Summer’ section from our website, "With correct eave overhang on the North of your building & thermal mass being shielded from direct solar gain we can control the increase in the ambient air temperature of the building. During the day heat gains from external temperature, the occupants of the building, and any electrical lighting and equipment, is absorbed by the exposed thermal mass of the building and releases stored cool within the thermal mass, thus limiting the temperature rise within the space to be within acceptable levels for human thermal comfort. By the end of the day the thermal mass of the building has in turn warmed up, and now as external temperatures reduce the heat can be released and the thermal mass cooled down ready for the start of the next day. However this "regeneration" process is only effective if the building is ventilated at night when the external air temperature has dropped below the internal temperature, to carry away the heat that has been absorbed during the day. This can be achieved through naturally ventilating buildings (opening windows etc.) or the use of automated ventilation systems. This reduces or totally eliminates the need for artificial cooling systems to be installed, thus reducing the overall energy consumption of the building to attain a comfortable living environment." When temperatures do not drop at night for 3-4 nights, our houses are still far more comfortable than outside, warmer than it would be if night ventilation could be achieved, but still a comfortable temperature. In our house we just use ceiling fans during those in-between days! We find that even when it is warmer in our houses in prolonged hot periods than it would be with air-conditioning, the quality of the air and feel of being inside the house is much nicer than what it would be with the everyday use of an air-conditioner – not to mention benefit that not using air-conditioning has on the environment. Hope this answers your question :)

Sorry to continue....the plan by Louise on the 20/01/2017.... But the laundry ( with internal access or through cloak room) and ensuite to the rear of the garage the master behind...... Then a Wir separating the master form the living or a bathroom...... The a fireplace if required against the western wall central in the house.... The entrance and small cloak room for the winter woollies against the garage and the other three beds at the front RHS with bath near.... The lounge/ kitchen/ dining in a similar layout but with minimal a walls blocking the view from the entry to the living/kitchen .... I like at lease a small wall dividing the living and lounge for the teenagers also.... If I get an chance I will sketch something up. Good luck this the paperwork... Plans are the fun part.

executing Owner Builder projects these days really is consolidated to projects that can be self funded - banks and building surveyors are becoming increasingly cautious when it comes to owner builder projects and fair enough too...... Experience/knowledge aside, unless you are retired, on long service leave or have a passive income and have money in the bank, it's questionable whether you'll overall save money when you factor your own time and risk into it.....after helping several clients with owner builds, and doing a couple of my own, (& I know what I'm doing) my opinion of this approach has shifted significantly over the past 15 years or so..........as a general pattern, it starts off as exciting, but the projects are harder to finish, and when the money runs out there's a big risk of being caught in no man's land where you've spend more than anticipated, the jobs unfinished but you need more money to finish it properly to either re-finance of release funds somehow...... My advice (for mental health!) is to approach these projects and engaged with this industry as professionally as possible with clear packaged proposals. Sure build some flexibility into the contract say for choices on finishes etc, but I'd now confidently advise people the best approach for construction projects, to minimise risk and for a most smooth process, is to "front end" investment in comprehensive design, documentation & specification that can then be clearly packaged/presented to a (reputable) builder who can then fix the quote and execute the construction stage far more effectively and efficiently than someone "having a go piecing it all together for the first time", regardless of whether you may have some close industry contacts as support.... Best of luck! Cheers PD :)

I really love the work of Ross Chapin, he has really influenced my approach to homes in general! He is a US (i think) based architect who champions small homes and has a concept called a pocket home. I've read a lot of his articles and he likes homes that are homey and cottagey and small neighbourhoods with common parklands and great greenspace access. One feature of his homes is they are typically 1-2 bedroom a thing he often does is replace what would in other homes a whole room with a nook. So for example, a hallway might be extra wide but have a nook for an office that could be closed off with a sliding door into a spare room. Or an attic space that can sleep grandkids, dining nooks off the kitchen so entertaining is possible, like an oversized bay window. Decent living spaces. His designs are worth a look at to get some ideas. https://rosschapin.com/plans/small-houses/ I've also stayed at a newly built unit for an elderly person. There was this large foyer space at the entrance with an extra wide door that was level with the paving, no lip at the entrance. It was designed so ambulance access would be easy in an emergency. The large foyer had cupboards with a laundry and storage, and then there was a bathroom directly across, again for easy emergency access. There was a phone in the bathroom too in case of falls. The whole area was tiled from door to bathroom for easy maintenance and access. The kitchen was simply run across one wall of an open plan dining and lounge area with like a corridor of tiling to designate it as separate. You can use flooring changes to create different spaces. It there were no awkward pokey spaces and it was the easiest place I have ever stayed for cleaning and organising. There is a universal access guideline, its worth checking things like bench heights etc... https://www.architecture.com.au/wp-content/uploads/Universal-Access-Policy.pdf
