Frequently Asked Questions

Can I build over a sewer?

Building near or over a public sewer may require a build-over agreement from the relevant water authority.

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.

Do I need planning permission for a loft conversion?

Many loft conversions are permitted development, but dormer size, roof alterations, and conservation area status may affect eligibility.

Can I build a two-storey extension without planning permission?

Two-storey extensions are sometimes permitted, but stricter limits apply to height, rear projection distance, and window placement to avoid overlooking neighbours.

Does my extension need to match existing materials?

While not always mandatory under permitted development, matching materials is often recommended for visual consistency.

Is planning permission needed for internal alterations?

Internal changes usually do not require planning permission unless the property is listed.
