Cirencester & the Cotswolds: Party Wall Rules for Cotswold-Stone Extensions
Cotswold-stone cottages in Cirencester, Tetbury and Stow crack easily under neighbouring works. Here's the Party Wall Act checklist — and why a Schedule of Condition is non-negotiable.
Cotswold-stone cottages look permanent, but ashlar and rubble-stone walls bedded in lime mortar are surprisingly sensitive to vibration and shifts in ground moisture. In Cirencester, Tetbury, Stow-on-the-Wold and Fairford, almost every rear extension, garden-room dig or loft conversion on a terrace triggers the Party Wall etc. Act 1996 — and skipping the process leaves both sides exposed when a hairline crack later opens up.
Why Cotswold properties need extra care
- Lime-mortar rubble walls flex under vibration from mini-diggers, breakers and steel installation.
- Shared stone party walls between cottages in Cirencester's Market Place and Dollar Street terraces are often only 225 mm thick — any cut for a new opening or steel is notifiable.
- Shallow rubble-trench foundations on Victorian cottages routinely sit less than 600 mm below ground, so a modern 1 m strip footing next door triggers Section 6.
- Conservation area and Listed Building Consent cover the look of the works. They do nothing to protect your neighbour from settlement — that's what the Act is for.
The Cirencester checklist
- Section 2 for any work to the party wall — new steels, chimney breast removal, raising the wall for a loft.
- Section 6 for excavation within 3 m of a neighbour's wall at a depth lower than their foundations (nearly every rear extension in a Cotswold terrace).
- Section 1 if you're building a new wall astride the boundary — common with side-return infills in Cirencester's town-centre yards.
- Schedule of Condition on every adjoining property, photographed inside and out. This is the single most valuable document you'll pay for.
- Notice served 1–2 months before the works start, allowing for the 14-day response window on top.
The Schedule of Condition is non-negotiable here
On modern brick semis you can sometimes get away without one. On Cotswold stone you cannot. Any pre-existing crack in ashlar dressing, any bulge in a rubble wall, any lifted flag in a garden path — record it before the digger arrives and it stops being a dispute later. £350 standalone, free when bundled with an Award.
