RICS Level 3 Building Survey in St. Keyne and Trewidland

A RICS Level 3 survey, also called a building survey, gives the fullest assessment of a property's condition available. Unlike a simpler check, it goes well beyond the surface to look at structural integrity, uncover hidden defects, and judge the condition of the main parts, including walls, floors, roofs, and foundations. For properties in St. Keyne and Trewidland, where many homes are of period construction, that extra depth matters. We physically examine structural timbers, probe accessible elements to assess condition, and photograph all significant findings.

The report sets out clear ratings for each defect, from urgent matters that need immediate attention to points for future maintenance. Our surveyor also explains the likely cause of any problem and gives cost guidance for repairs. That can be invaluable when negotiating the purchase price or planning renovation work after completion. Our reports run to 40 pages or more, compared with the 10-20 pages typical of a Level 2 survey, so we can give a fuller picture of the property's true condition.

Many properties in St. Keyne and Trewidland sit in the group where a Level 3 survey is strongly recommended. That includes buildings over 70 years old, listed buildings, homes that have been significantly altered or extended, and properties with non-standard construction such as timber frames or cob walls. With at least 11 listed buildings within the parish, including the Grade II* Church of St Keyne and historic farmhouses like Lametton Barton and Trussel Farmhouse, the case for a detailed assessment is plain. We know the extra considerations that come with heritage properties and adjust our inspection to pick up issues linked to historic buildings.

• Roof structure and covering
• Walls, foundations, and substructure
• Floors, stairs, and joinery
• Chimneys and flues
• Dampness and timber condition
• Outbuildings and boundaries

St. Keyne and Trewidland parish covers a wide mix of properties, from small agricultural dwellings to substantial farmhouses and modernised barn conversions. The 2021 census recorded a population of 795 across approximately 329 households, with Trewidland itself made up of around 50 dwellings plus approximately 80 outlying properties. That mix means buyers may come across everything from compact period cottages to large detached homes, each needing a different approach to assessment. The area sits within the Looe Valley, designated an Area of Outstanding Natural Beauty, which shapes both the character of the housing stock and the planning issues for any renovations.

At least 11 listed buildings sit within the parish boundaries, giving the area a strong heritage profile. The Church of St Keyne has Grade II* listed status, while places such as Lametton Mill, dating from the 17th century, and South Lankelly, with rare 16th-century timber mullioned windows, sit at the older end of the housing stock. Charming as they are, these properties often raise structural questions that need close inspection. Traditional Cornish construction here usually means solid stone walls, sometimes with rendered cob or cob infill, together with timber-framed elements that behave differently from modern cavity wall construction.

Recent activity in the area includes a detached property in Trewidland selling for £462,500 in October 2024, while a 4-bedroom detached bungalow is currently listed at a guide price of £675,000. Those figures underline why a full survey matters before anyone commits to purchase, especially with the 11% fall in property values recorded over the past year. The drop from the 2022 peak of £405,111 creates chances for buyers, but it also means proper due diligence is needed so the asking price reflects condition as well as location.

Trewidland village itself has a Primary School and Pre-School, which matters for families looking at the area. The Dobwalls and Trewidland Neighbourhood Development Plan, adopted in May 2024, sets the direction for future growth and includes policies on flood management, soil quality protection, and tree retention. For buyers, those local planning issues add another layer to property assessment, especially where future development or environmental policy could affect a home.

Market data for St. Keyne and Trewidland points the same way, with prices down by 11% over the past year and sitting 27% below the 2022 peak of £405,111. Even with that correction, the longer trend remains upward, with prices rising by 34.6% over the last decade. For buyers, that may create scope, but it also means thorough due diligence matters if a property is to represent real value. Current conditions mean some homes may sit below their true worth, while others may carry hidden defects that change the figure altogether.

The area's appeal within the Looe Valley AONB, along with strong community links and good schools nearby, keeps drawing buyers looking for a rural Cornwall lifestyle. Properties here range from modest cottages to substantial family homes, with the recent sale at £225,000 showing the lower end of the market and premium properties reaching well into the £600,000s. The Trewidland Primary School and Pre-School serve the local community, which makes the area especially attractive to families. Whatever the purchase price, a full survey gives essential protection for what is likely to be one of the largest financial commitments we ever make.

The Dobwalls and Trewidland Neighbourhood Development Plan, adopted in 2024, gives useful insight into future plans for the area, including support for existing businesses and careful management of development. Knowing those local planning policies can add another layer to property assessment, particularly where a home might be affected by future development or environmental initiatives. Our surveyors can flag any specific planning or environmental concerns identified during the inspection.
