Basement Planning Permission In Garstang, Explained Properly

Garstang basement projects fall into two genuinely different categories for planning purposes, converting space that already exists, and excavating something new. The first is often achievable under permitted development, the second almost never is.

Where a Garstang project alters the building’s external appearance, new light wells, external stairs, altered windows, planning permission is typically needed regardless of what’s happening below ground.

We assess your specific Garstang property honestly against these distinctions before recommending anything, rather than assuming either way.
