RICS Level 3 Building Survey in Highmoor

The geology of Highmoor presents specific challenges that our inspectors assess on every survey. The village sits on clay-with-flints capped chalk uplands at around 150 metres elevation, and this clay-with-flints substrate is known to be susceptible to shrink-swell behaviour. During periods of extreme wet or dry weather, the clay can expand and contract, putting pressure on foundations and potentially causing subsidence or heave issues. Our inspectors are trained to identify the signs of this type of ground movement, including characteristic crack patterns in walls and indicators of differential settlement.

Highmoor contains a significant proportion of period properties, with the dominant property type on Highmoor Street being period flats built between 1800 and 1911. These older buildings often feature solid wall construction, traditional timber floor joists, and pitched roofs with original tiles or slate. While these features add considerable character to the village, they also bring potential defects including rising damp, penetrating damp, timber rot, woodworm infestation, and general wear and tear on roofing materials. The 20 properties sold in the RG9 area over the past year include a mix of these period flats and larger detached homes, many of which would benefit substantially from a detailed Level 3 assessment.

Several properties in the area carry listed status, including Highmoor Hall with parts dating to the 17th century, Highmoor Farmhouse with its 17th-century origins, and the Church of England parish church of Saint Paul at Highmoor Cross built in 1859. Listed buildings inherently require detailed surveying due to their historical significance, unique construction methods, and the specific regulations governing any alterations or repairs. Our surveyors understand these complexities and will provide you with practical advice on what any future works might involve.

Properties in Highmoor face particular structural risks that our Level 3 Surveys address comprehensively. The clay-with-flints geology means that foundation movement is a key concern, particularly for older properties with potentially shallower foundations than modern standards would require. Our inspectors look for signs of past or ongoing movement, including cracks in walls, uneven floors, and doors or windows that no longer close properly. In our experience, properties on the higher ground around Highmoor Street are particularly susceptible to these issues due to the underlying geology, and we always conduct a thorough assessment of foundation conditions.

The age of many properties in the village means that outdated services are frequently encountered during our surveys. Original plumbing systems, historic electrical installations, and old heating systems all require careful assessment. Properties built before 1911, which dominate Highmoor Street, often have wiring and plumbing that would not meet current regulations and could pose safety risks. Our survey report will highlight any concerns regarding the condition and safety of these systems, helping you plan for necessary upgrades and factor these costs into your purchase decision. We've found that many period properties in the Chilterns require complete rewire and new heating systems within a few years of purchase.

If you're considering purchasing a listed property in Highmoor, our surveyors understand the additional complexities involved. Listed Building Consent is required for many alterations, and our report will help you understand both the current condition of the property and any future work you may want to undertake. Properties like Highmoor Hall and Highmoor Farmhouse have significant historical fabric that requires specialist knowledge to assess properly. This knowledge is invaluable for listed property purchases, where unexpected repair requirements can quickly become expensive and where inappropriate repairs can cause legal issues with the planning authority.
