Accessible thresholds are quite common and installed where a wheelchair needs to roll over a door threshold easily. The building regulations stipulate that such thresholds cannot have any protrusions greater than 15mm – thus allowing a standard wheelchair (with small wheels on the front and large wheels on the back) to roll over it.
However our customer used a wheelchair with 4 small castors and propelled herself using her single leg. As such – our threshold needed to be completely level with zero tolerance.
John Ford Group were able to design and install the new doors such than when the wheels crushed the pile of the carpet – the threshold became perfectly level – in turn enabling the customer to access the garden easily.
The installation was signed off by Building Control (free of the normal charge due to the installation being a disability adaptation)
