RICS Level 2 Survey Barnack, Peterborough

Barnack owes much of its character to its geology and long history. Barnack Rag, the deep honey-coloured limestone quarried here for centuries, was used in buildings such as Peterborough Cathedral and Ely Cathedral. A lot of the village is built from that same stone, so we look closely at how it has aged. Our surveyors understand the quirks of limestone construction, from moisture getting in to weathering and movement in older stone-built homes. We check the pointing, the stone faces, and any signs of deterioration that may need attention.

Under Barnack, the local ground brings its own questions. The village sits on Jurassic oolitic limestones and clays, and that can lead to shrink-swell behaviour in clay soils during drought or after heavy rain. Add in the quarrying that created the Hills and Holes landscape, and some parts of the area may have ground stability issues that a standard inspection needs to consider. Our chartered surveyors are used to these conditions and look carefully for movement, cracking, or subsidence linked to the underlying ground. The Barnack Hills and Holes area, now a National Nature Reserve and Site of Special Scientific Interest, is a clear reminder of the limestone extraction that shaped the landscape over centuries.

Collyweston stone roofing is another defining feature of Barnack homes. These steep roofs are attractive and historically right for the village, but they need specialist knowledge to assess properly. Our inspectors look closely at slipped tiles, worn verges and ridges, and the condition of parapet walls or chimneys that often go with these roofs. Properties such as Close House on Jack-Haws Lane, a Grade II listed C18 house with its original Collyweston stone roof, show the kind of traditional construction we see regularly. For homes in the Conservation Area, covering the historic core of the village including housing, the school, shop, and two churches, we provide clear notes on anything that could affect your plans.

Barnack’s Conservation Area, designated in June 1975 and extended in 1990, covers the historic core and includes a remarkable range of notable buildings. From the Bath House or Banqueting House, a Grade I listed building, to the medieval and Georgian properties on Station Road and School Road, the village has an unusual concentration of historic architecture. Our surveyors are experienced in assessing older homes and know the care that listed buildings require. We identify alterations that may need listed building consent and explain the upkeep that comes with owning a historic property in this special Cambridgeshire village.

Our work across Barnack has highlighted several recurring issues that buyers should have in mind. Damp is especially common in older stone-built properties, particularly where ground levels are high or existing damp proof courses have been bridged over time. Many homes in the village are also affected by outdated electrical systems, often with consumer units and wiring that no longer meet current regulations. We check electrical installations carefully and flag any concerns that need a qualified electrician’s attention. Older wiring in period homes, especially where it has not been updated for decades, can create safety risks that need prompt action.

Roof conditions need close attention in Barnack because Collyweston stone roofs are so common here. Repairs and maintenance can be costly, so our surveyors inspect them carefully for slipped or missing stones, damaged flashings, and the condition of any flat roof sections to outbuildings or extensions. Because Collyweston roofing is so distinctive, repairs often need specialist contractors who know traditional materials and methods. Our reports will say if the roof looks likely to need significant investment in the near future, so you can budget properly for maintenance. We also check chimney stacks and parapet walls, which are common on Barnack properties and can let water in.

We often find movement and cracking around window openings and door frames in older properties, especially where extensions have been added to the original building. With the clay geology in the area, our surveyors watch closely for subsidence or ground movement linked to shrink-swell behaviour in the soil. Historical quarrying in parts of the village adds another layer, as some homes may stand on or near former quarry sites. We look for diagonal cracking, sticking doors and windows, and uneven floors that could point to structural movement needing further investigation.

On newer developments, such as those on Uffington Road where outline planning permission was granted for up to 80 residential dwellings, we assess modern construction methods and compliance with building regulations. Even fairly recent homes can have defects caused by workmanship, materials, or design, and our inspection is detailed enough to pick these up before completion. The three-bedroom detached homes completed at Sissons Close in 2021 sit at the newer end of Barnack’s housing stock, and while they usually raise fewer issues than period homes, a survey still gives useful reassurance about build quality. New build properties can still have snagging issues, and we will identify them before they become bigger problems.
