Why Basement Conversions Are So Popular
With limited outdoor space and strict planning controls, London homeowners are looking downward forexpansion. A basement conversion
can add an entire new floor of usable area without altering the property’s external appearance.
Planning and Legal Considerations
Basement projects often require full planning permission, especially in conservation areas or when external changes such as lightwells
are added. At PAR Group, we manage the planning process end-to-end, ensuring compliance with local borough regulations.

tailored to each property. We use advanced tanking systems and cavity drainage membranes to ensure
the space remains permanently dry.
