Someone I know (my wife actually) wants outward opening doors on her garden she-shed. I've told her that the wind will catch the doors and rip them off their little hinges. I've given her the option of a sliding patio door or inward opening french doors (like the ones that work PERFECTLY on the Juliette balcony upstairs) but she still ain't having it.
Come on guys! Back me up! Pleeeeeze!
It depends on the situation
Outward opening doors are normally fitted on shed doors and most cabins / garden offices…as it doesn’t impede any space internally.
Wind may or may not be an issue, it largely depends on whether your garden is exposed to the wind or not….and direction of the prevailing wind.
Also think about traffic flow, when you open a door inwards, it makes you naturally turn as you go through the door away from the hinge side to avoid having to walk around the opened door - that can be a benefit or annoyance, depending on how the room is set out.
One more thing, if the garden-she shed is going to have planters or pots outside for flowers, then an outward opening door might not work so well.
If it’s a space where she might work, then during the warmer months the doors might want to be fully open - that would be nicer with external doors.
And a final note: inward opening doors are more likely to,leak from rain and need a more complex cill arrangement - no,issue if you ar buying an off the shelf door set like upvc, not so easy if it’s a shed type T and G door.
