Can a soil report be reused if I only extend my home rather than rebuild?

Often, yes, if a report already exists for your property and is still within its valid window — an extension can genuinely rely on the same underlying soil classification as the original build, provided conditions haven’t changed.

Your engineer confirms whether the existing report is still genuinely applicable to your extension’s specific footprint and loads, and may recommend supplementary testing if the extension sits over ground not originally tested.
