Scottish Building Standards: Domestic: Section 3: Environment - A summary of changes in 2007 edition (Version 1)

TRADA image

The most significant changes to Section 3 relate to improving the provisions for the elderly, infirm and disabled. The major goal is to raise the standard of accessibility for all in dwellings from 'visitabe' to 'liveable'. This change in philosophy has led to amendments in both Section 4: Safety and Section 3: Environment, the former section is covered in a separate TRADA Construction Briefing on Scottish Building Standards: Section 4.

This Construction Briefing gives readers a summary of the amendments made to section 3 combined with some more in depth commentary which explains the practical implications of the changes.

This sheet also examines the impact that other regulations have had on section 3, in particular the Code for Sustainable Homes which included increased guidance on the storage and safe delivery of biomass, and modified guidance on ventilation which was reviewed as part of the improved air tightness requirements in Section 6: Energy.
