Change agents
LEGISLATION
• Chronically Sick and Disabled Persons Act 1978
• Disabled Persons Act 1982
• Building Regulations 1994/2000
• Disability Discrimination Act
Equality Commission for N. Ireland
The need for Regulation
• “The provision of advice, guidance and persuasion over a number of years have not raised awareness of designers and house builders to substantially improve access to dwellings for disabled people. There does not therefore appear to be an effective alternative to Regulations” Department of the Environment
Positive Enforcement
• Regulation is probably the most potent weapon in the drive towards an accessible environment for all.

Point of entry
Principal entrance
Point of entry
Approach to principal entrance or common entrance
Approach to Dwellings
• The approach from point of entry to principal entrance– Level
• Firm and even surface• Maximum gradient 1:20• Minimum width 900mm
– Ramped • Maximum gradient 1:12 for length < 5m• Maximum gradient 1:15 for length < 10m• 1200mm long landings
– or a combination
Steep sites
• “Steep” plot gradient to Principal Entrance (greater than 1:15 or 1:12 < 5m travel distance)
– an “alternative entrance” can be used
• Plot gradient to Alternative Entrance (greater than 1:15 or 1:12 < 5m travel distance)
– a “stepped approach” can be used
