These 4 photos showing some window tinting done to add to my priviouse article . A house in Penguin Tasmania overlooking the sea with privacy an sun problems using a dark neutral based film showing one sheet of glass done an one with out with the second picture showing the glare reduction on the floor as a comparison . This demonstrates little reduction in quality of views overlooking the sea but offers many benifits to the customers with out having to close blinds / curtains etc. The other two showing the full reflective film on a commercial shop front with views from both inside and outside as a comparison . ( please note; taking photos facing windows will often result in misleading picture quality due to any glare present , thus resulting in misleading darker looking window views than what normally results from using most tinted films .) The actual light reduction difference between these two films is approx 9% with the reflective being the darker of the two and comparable to a popular dark grey low reflective shade that's also widely popular . Any one requiring some unbiased comments regarding this subject are quite welcome to call me . Although I live in Tasmania , I do offer my services not only Australia wide but also overseas if the need arises . As to the life expectancy of these products . As these are manufactured world wide , the quality ( or lack of) plus the degree of experince and willingness of the installer to make sure they want to try an do a good job ; can make a Hugh difference to the last -ability . Therefore, take care on choosing the film and installer ; and don't buy on price alone. Gary. Protek window tinting (Tasmania )

Keeping the heat out as much as possible is important, before it passes through the glass. Renshade can be installed temporarily and removed in autumn. https://www.goingsolar.com.au/what-we-do/brands-and-products/renshade-australian Or install external blinds if you’re allowed to. While closing internal window coverings helps, keeping the heat out before it passes through the glass is much better. Do you own the apartment? If so, you could consider installing multi split aircon units in the bedrooms. That way you will only need one extra outdoor unit. Or, if it’s not possible to add an extra outdoor unit, could you swap the current outdoor unit for one that would power three indoor units? One for each bedroom and one for the living area. As well as cooling they also provide the most energy efficient form of heating. If that’s not possible, ceiling fans might help. If you are renting your options are more limited. Portable air conditioners for very hot days. They’re noisy and expensive to run but they do the job in a small room like a bedroom. There are also some heat shifting systems that could also shift cold air, but they need a roof cavity, which probably won’t suit your situation. Best if luck.

my suggestion has an ens and wiw and uses the old bedroom door for a linen cupboard, although the toilet could be placed at either end to be closer to the original sewerage, this arrangement allows for more privacy for the toilet, more standing room near the shower, wall space for a towel rail and room in teh wiw for a chest of drawers..the vanity is over 2m long with cabinet under the (one or twin) sinks and open shelves next to the toilet for towels .. and, while you're adding the new ens, it would be worthwhile to plan the new access to the kitchen and new laundry

My daughter ran her business from her bedroom until they could afford a 3 bedroom house, their 2 bedder with two boys and no where else to fit an office was a very difficult time which thankfully they all survived. Having your office in your bedroom should be avoided at all cost, as you never leave the office behind as my daughter found out. Your bedroom is where you go to relax , I certainly wouldn't give up my sanctuary for anyone, even my kids. You are there full time so it makes sense. Your house already has enough rooms, except for making a small change to allow for another bedroom albeit small next to the bathroom as per my suggestion, Both of these rooms have space for the boys to have a desk (they don't need a lot of storage being part time) The desk in the living area can be built in to hide an office. This is a low cost solution and won't damage resale value. If down the track you can afford the new deck, try to work out to fit a room underneath as a hang out (media) area for the boys. not sure about WA but rooms like these in some states can have ceiling height at 2100, depends on what name!! you give them. My son is in a similar situation to you, except he now lives in a Studio Apartment in Sydney, so when he has his two kids 50 50 they make do in that space and seem to manage very well.
