Regulations & Law 🏛️ Designing Buildings ⏱ 2 CPD Hours Free

About this CPD Resource

Inclusive design requirements under Approved Document M, covering accessibility for new and existing buildings including dwelling access categories and visitability standards.

Approved Document M (Access to and Use of Buildings) sets the minimum requirements for accessibility in new buildings and material changes of use in England. Understanding the three dwelling categories is essential for residential architects as many local planning authorities mandate proportions of M4(2) or M4(3) dwellings.

Learning Outcomes

  • Understand Part M categories M4(1), M4(2) and M4(3)
  • Apply accessible and adaptable dwelling design standards
  • Design compliant accessible entrances and circulation routes
  • Understand the interface between Part M and BS 8300

Why This CPD Matters

The regulatory framework governing construction in the UK has undergone more change in recent years than at any time since the introduction of the current Building Regulations regime. The Building Safety Act 2022 — the most significant piece of construction legislation in a generation — has introduced new roles, new duties and new accountability mechanisms that affect everyone in the construction supply chain. Alongside this, updates to the Approved Documents covering energy efficiency (Part L), ventilation (Part F), overheating (Part O) and fire safety (Part B) have changed the technical standards that new buildings must meet.

Keeping pace with regulatory change is a professional obligation for construction practitioners. Advising clients or designing buildings based on outdated regulatory knowledge can result in buildings that fail to achieve compliance, costly remediation work and, in serious cases, professional liability. This CPD from Designing Buildings provides the regulatory knowledge that construction professionals need to practise confidently in the current environment.

Key Topics and Industry Context

The regulatory landscape for UK construction covers a wide range of legal and technical requirements. Building Regulations set the minimum technical standards for the design and construction of buildings in England (with separate but similar regimes in Wales, Scotland and Northern Ireland). Planning legislation and policy — including the National Planning Policy Framework, local planning policies and permitted development rights — governs what can be built and where. The Building Safety Act 2022 has introduced specific requirements for higher-risk buildings including a new regulatory gateway process, a safety case regime and requirements for the maintenance of a golden thread of information throughout the building's lifecycle.

This resource from Designing Buildings addresses regulatory knowledge that is directly applicable to construction practice. Construction professionals who maintain current regulatory knowledge are better placed to advise clients accurately, design compliant buildings and manage the regulatory process efficiently.

How This Fits Your CPD Requirements

Regulatory knowledge is a core competency requirement for most construction professional bodies. RIBA's mandatory core curriculum includes legal, regulatory and statutory compliance as a required topic area. RICS requires members to maintain competency in relevant legislation and regulation. CIOB includes understanding of building regulations and construction law in its competency framework. Architectural technologists (CIAT) are required to demonstrate competency in legislation and regulation as one of their 10 core competency areas. Structured CPD on regulations and law from recognised providers is recognised as valid formal CPD by all major construction professional bodies.

What is the difference between M4(2) and M4(3)?
M4(2) (Accessible and Adaptable) dwellings are designed for use by most people and can be adapted for wheelchair users. M4(3) (Wheelchair User) dwellings are specifically designed for wheelchair users.
When is M4(2) or M4(3) required?
M4(2) and M4(3) must be specified in planning conditions. Many local planning authorities now include policies requiring a percentage of new dwellings to meet these standards.
Does Part M apply to extensions?
Part M applies to material changes of use and extensions to buildings other than dwellings. Extensions to existing dwellings are not required to meet Part M.
