we successfully used Sarlon roller blinds on the outside of windows...make sure the blind is held out from the window to maintain air flow We also created a screened outdoor room using black Sarlon cloth attached to frames enclosing a verandah (access through an old fashioned fly screen covered in Sarlon)...initially to keep out the sun but it also did a great job of keeping out bugs and keeping inside warmer in cold weather..the black Sarlon has the effect of looking through fly screens thus improving the view looking out and obscuring the view looking in during the day...i suggest you double check the use of double glazing in the tropics as you need to allow heat to escape overnight and a window covering would be better on the inside to keep heat in during short periods of cold weather

Thank you My Beautiful Abode for your comment. The blind installer informed us that the blinds can't be released from their brackets and that once installed, a blind and it's bracket has to be removed as a unit. However, the window manufacturer demonstrated to us how the screens can be manipulated in sideways and then forced into position. Each time this procedure is carried out the window frames and fly screen frames are prone to damage. We don't believe that the present bracket design "is fit for purpose" and would not have purchased from this manufacturer of blinds had we been aware, or advised, that the blinds could not be released from the brackets.

The price is real ... Project builders can build for approx $850/m2 and sell most project homes for around $1000-$1050/m2 (base price!!!!). Where you will need to shell out more is when you look into things like :- The kitchen package (laminex benchtop & Carcass) could be $3000-$5000 price difference just in the benchtop; The external cladding could be cheap masonite or vinyl cladding system which will be outdated before you've moved in or you could be looking for something classy like James Hardie SCYON cladding (Stria, Linea, Axon) cladding systems - add $10,000 - $12,000; The tiles in bathrooms - could be $1.000 to $5,000 difference in prices here; The type & quality of timber flooring (if any), the type and quality of carpet could be cheap $3,200 carpet package for entire home or it could be $8,000 carpet with quality underlay which is LOW VOC (important if you have kids and love your family) or $18,000 for timber floor or it could be $45,000 for european parquet flooring throughout if you have an aversion to carpet because of allergies; The type & quality of PC items such as taps, toilets, vanity, shower rail / head, kitchen sink, towel rails right down to the toilet paper holder - there could be $5,000-$9,000 price difference here; The type and quality of main kitchen fittings such as cooktop, rangehood, oven (could be $900 package for an unknown brand or it could be $2,200 for something decent 600mm wide or $3,500 for something decent 900mm wide or it could be Miele and cost $5,000. Then if you look at the windows and sliding / stacker / bifold doors ... these could be cheap aluminium with 4mm float glass or you could be wanting 100mm x 50mm commercial aluminium with 6.38mm laminated tinted glass with low-e glass to all your western windows or you could be more interested in PVC windows with a steel internal frame with double glazing and blinds built into the double glazed unit with tilt and turn doors and windows - price difference is at least $10,000-$30,000; That's about 75% of the major decisions that you might want to investigate further. The biggest factor you'll be hit with is a little thing called 'site costs'. This is where project builders get to charge like wounded bulls. Any land that you find which is not 'dead level' will incur additional fees (counted in the thousands) and any soil classification which is not 'M' class substrata will incur additional fees. You may find an additional $40,000 - $200,000 slapped on for these charges and it will be disguised as "i'm so sorry but your land will need piers and footings and some serious excavation - there is nothing that we or any builder can do about it" Then if you want to upgrade the tap and kitchen sink you will find their pricing regime is out of this world. I built a single level home for a pharmacist and his family in north sydney back in 2011 and quoted $750,000 (it was a big home - almost 300m2) and the client got a bit edgy with me after months of discussions and decided to approach a few project builders after seeing advertisements for single level home packages starting from $370,000. After they had gotten part way through their enquiry process and had a site inspection and soil classification test carried out they were presented with a quote for $610,000 and that was without any of the travertine or double glazing or spray foam insulation or acoustic walls and home theatre systems that I had proposed. I think the shock of a project builder jumping from $370k to $610k overnight scared them more than my initial quote of $750k. We finished up at $830k after the lady had made all her decisions including $100,000 joinery (cabinetry for kitchen, laundry, custom vanities, walk in robes, built in robes, study) and $80,000 of Miele appliances (including $3,600 coffee machine) ... strangest part was SHE DIDN'T COOK. There was a massive bbq area with built-in bbq and wine fridge and indoor and outdoor fireplace and custom landscaping and the list went on. My point is, I believe you will get much more value - both immediate value for you and your family to enjoy when you move in AND resale value (people do appreciate quality and will pay for it) if you build with a proper builder and architect / designer who designs the size, style, external finishes and internal products to be how you want them and a quality that will last. If, however, you do not have the capacity to invest somewhere around $700k - $800k for this monstrous 52 square home you are looking at, but need the room to accommodate your family, then by all means investigate further with the project builder. I've been doing a touch typing course lately to help with my report writing and it has been quite interesting just rattling away at the keyboard without looking and giving you the best of my experience over the last 10 minutes. Hope it's of some benefit to you and your family. Best regards, Steve.

Zaffa, if you pop down to your local Spotlight store, they have examples of all types of blinds and shutters Great to get an idea of what each look like, various options, pricing, etc, etc. Only, NEVER EVER order shutters from them! I ordered mine from them when building and they took longer than the house to make them! Ended up having to use temporary blinds for months until they arrived. Also, they really let a lot of light in, so not great for kids bedrooms at all! Romans and rollers keep out much more light if you don't want to go down the full curtain with pelmet option. You can also go automatic blinds with rollers if you're concerned about boys touching the blinds too much. Adds around $500 per window I think I was quoted, so depends on your budget. Cannot automate roman blinds apparently. Best of luck in your decision.
