The poor design decisions captured around the world include a toilet installed directly underneath a worktop, and a disabled access ramp, the end of which is entirely blocked by a staircase.
They say if you want something done properly you should do it yourself - and the people who took these photographs will likely follow that advice to the letter from now on.
The comical snaps shared online showcase some of the worst building work ever undertaken.
Examples include a sinister looking slide which hovers over a black pit - turning a children's playground into a death trap.
One amateur handyman had a go at installing a toilet, only to add a work top over the loo, rendering it useless.
Sparking serious safety concerns, another hapless workman installed a tap directly over two plugs.

Not built to last! One amateur builder got these door handles the wrong way around
Going nowhere! A concrete block has been built onto these railway tracks, meaning trains won't be able to pass by

Take the stairs! Despite having escalator railings, these stairs were just regular steps

What's behind THIS door? One rogue builder trapped this door shut by building a railing over it
Low tech! This laptop was completely mixed up, with the mouse, screen and the keyboard in the wrong place
No room with a view! This balcony was a little pointless as it didn't serve any room
No way out! The ceilings were little too low for this escalator, making it very dangerous
Not very secure! This fence was meant to keep people out, but stopped halfway through
Nowhere to go! This strange structure featured both a ramp and some stairs but didn't lead anywhere
Long way down! One rogue builder installed a door that was completely inaccessible
Just for show! These stairs only lead their users to the ceiling, making them pointless
That sinking feeling! This tiny sink was much too small to be used by the man in the picture
A bit of a squeeze! These stairs are only accessible to very slim people due to their closeness to the wall
No privacy! A lone toilet sat at the end of this line of sinks, completely exposed to everyone in this public bathroom
Dodgy design! A step ladder is needed to reach this door, which is too high up
All style, no substance! These rather grand looking stairs didn't actually lead anywhere
