A good Architectural door hardware supplier would have the goods, some photos following cheers,

Seeing as though it appears you have 900mm depth internal depth you could consider setting the more simple/cheaper folding doors in as far as possible (not in line with the passage, but say 200/250mm in from it) just so the washing machine fits. If you then sort out the leaf break-up to be minimal (300-350mm ish) you may be able to then have the doors sitting back against the wall either each side or at one end without projecting out too far in the passage space.....sometimes I set up kitchen mixing centre doors like this to avoid the exact issue...remember if you go the the pocket door options you take width out of the space and when it's relatively tight like yours the extra 100/150mm may be better used for benchspace/storage....options options! Good luck :)

The pivot doors that Julie has posted are out of character , and like most posts so far , I like the existing door . However , being weird , I'd leave the flyscreen , and the frosting -- I think it all suits . Maybe needs a coat of paint -- imagine the 2 lower exterior infill panels on the door in a bright red or orange to lift the look , tie in with the brick , add some colour ? Or do the whole door and the wrought iron scrolls of the screen in 1950's pastel mint green or apricot -- the reverse of modernising ! Also unlike most , I don't particularly like the wooden panels above the door and the bay window -- I know some will scorn , but I'd either plaster smooth , or maybe go with glass ( yes , frosted ) with little net curtains -- I suspect the outside view of this isn't really visible ( under a veranda I gather ? ) but to me , it would tidy the inside look , look period , and tie it all in . Then , add a red leather lounge suite or chairs ( depending on that rooms use ) and at least 1 big colourful abstract painting -- that is the way to add class and colour and some modern looks IMO , not by adding an ultramodern door to what is essentially a 40 year old house . Just my thoughts .

I've had no luck with finding a door supplier that can provide the a specific door. Thought I'd try my luck on here. Details are: New Build residential property in Brisbane Aluminium pivot enrty door 3 or 4 x vertical glass panels 2400 x 1500 or 2400 x 1600 TIA
