is required when making detailed proposals for developments which are not covered by a householder application or permitted?

This query appears to conflate UK planning law with the OTHM Level 7 Diploma in Strategic Management and Leadership. The diploma curriculum focuses on strategic direction, organisational capability, and governance, not statutory planning permissions or householder applications. "Detailed proposals for developments" outside permitted development typically require full planning permission under the Town and Country Planning Act 1990, not a management qualification. If you are researching how strategic leaders manage regulatory compliance or risk appetite regarding property development, the Level 7 units cover stakeholder mapping and governance frameworks. However, specific planning legislation falls outside this master’s-level management programme. Please clarify if you need guidance on the diploma’s strategic units or separate legal advice on planning applications.
