Sherpa,
The DDA as you say is about "reasonable adjustments" and in my opinion is best considered as a risk assessment much like the FRA (except without the guidance document!!).
There is no way of achieving "compliance" with the DDA, but you can minimise the risk of a claim, and I would assume that compliance with anational standard would be a good example of minimising the risk.
The problem is that there has been a "knee jerk" reaction to the DDA with many unnecessary features being introduced and in many cases the level of access has actually been reduced following the alterations.
I think the problem is that each scenario has to be assessed on its own merits. If the scenario you are discussing is in a local authority leisure centre or a GP's practise, then alterations as described above may well be a suitable solution (because it may also address the need for vision panels), although self closers with a suitable opening force may also be a more "reasonable" solution.
If it was a small starter unit, and none of the staff had an identified need, then the above solution would definitely be onerous, and could alternatively be addressed if and when a need is identified.
