Alteration to Premises
Any modification, extension or conversion of premises should be planned to meet the Workplace (Health, Safety & Welfare) Regulations 1992 since the alteration or addition must comply with the requirements when brought into use as a workplace.
Examples of such changes include conversion of a large building into a number of smaller work units, conversion of a private house (or part of it) into a workplace and a radical change of use for a workplace which involves structural alterations.
