Believe me, but you don't want to own a custom-made, custom sized aluminium gas-strut window that has been made cheaply as so much can go wrong if the quality is not there. Either find the money for a properly designed and engineered gas-strut window, that will be a wonderful feature, or go with a sliding window that aligns to your price expectations.

If you do find a company that designs, engineers and builds specialized, custom windows to a good, quality standard, at a cheap price, then be sure to let me know!

Best of luck,

Are gas strut windows worth it in comparison to bi fold windows? My concern with these is that it's all or nothing. Any views anyone ?

Flip up and bi-fold are indeed "all or nothing" options that can be tricky to screen too. Both also rely heavily on well-engineered operating mechanisms and as such come with increased potential for problems.

I once stayed in a house on North Stradbroke Island which had a large flip up gas strut supported timber framed window over the north facing kitchen sink with views to Cape Moreton. (I now wish I had a photo to share, but sadly I was too much in the moment to take any.) Standing at the sink, looking north over the Coral Sea with Humpback whales breaching in the distance was one of those forever moments. Plus, our elevated situation seemed to reduce the number of insects that came through the unscreenable window. In that case I wouldn't have compromised on spending to get that window out of the way. For just about every other context I would opt for a less complex, less costly, screenable, servery style window.
