 Modern architecture is increasingly required by law and recognised good practise to incorporate better accessibility at the design stage.In many countries, such as the UK, the owners of inaccessible buildings who have not provided permanent access measures are still required by local equality legislation to provide 'reasonable adjustments' to ensure that disabled people are able to access their services and are not excluded.These may range from keeping a portable ramp on hand to allow a wheelchair user to cross an inaccessible threshold, to providing personal service to access goods they are not otherwise able to reach.
