Planning permission for permitted development conversions
Planning permission for permitted development conversions—such as office-to-residential—typically adds 20–40% to the Gross Development Value before a single brick is laid.

In property development, significant value is created not just through construction, but through 'planning gain'. Permitted Development (PD) rights in the UK allow certain types of commercial buildings, such as Class E (offices, light industrial, retail), to be converted into C3 residential dwellings without requiring a full, protracted planning application. Instead, developers use a streamlined 'Prior Approval' process.
An empty, outdated office block has a relatively low commercial value. However, the moment Prior Approval is granted to convert that block into 20 residential apartments, the underlying land value instantly recalibrates to reflect its new, higher-value residential potential. Developers often acquire commercial assets unconditionally, secure the PD rights, and then either sell the site to a builder for an immediate 20–40% profit (flipping the paper), or secure development finance against the newly uplifted value to fund the construction themselves.
