RICS Level 3 Building Survey in Morwenstow

The average property price in Morwenstow stands at £561,425, with detached properties averaging £432,500 and semi-detached homes at £585,000. This significant investment makes a comprehensive RICS Level 3 Survey essential before committing to purchase. The premium pricing reflects the desirable nature of this rural coastal parish, but it also means that any hidden defects could prove costly to rectify. With prices having risen 31% in the last year, buyers are investing substantial sums in a market where properties can still be found at around 7% below the 2022 peak of £601,000.

Properties in Morwenstow span several centuries of construction, from medieval manor houses like Tonacombe Manor (Grade I listed, built in the early 16th century) to Victorian and Edwardian farmsteads converted into residential homes. This diverse housing stock, while beautiful, presents varying risk profiles that only a detailed structural survey can properly assess. The Church of St Morwenna and St John the Baptist (Grade I listed, with some Norman remains) and The Old Vicarage (Grade II* listed, built in 1837 for Reverend R. S. Hawker) exemplify the age and character of buildings in this area. The Coombe Valley, in particular, contains a notable concentration of historic buildings that showcase traditional Cornish construction methods.

The coastal location of Morwenstow, situated on high cliffs with panoramic views, brings specific considerations for property condition. Coastal erosion, salt air exposure, and exposure to harsh weather conditions can accelerate building material degradation, particularly on exposed elevations. Our surveyors understand these local environmental factors and pay particular attention to roof coverings, external render, and structural elements that may be affected by the marine environment. Properties like Hawker's Hut, a Grade II listed building constructed from driftwood and timber retrieved from shipwrecks with a distinctive turf roof, demonstrate the unique construction approaches that have evolved in this coastal parish.

• High-value properties requiring detailed assessment
• Older construction with potential hidden defects
• Coastal exposure affecting building materials
• Listed buildings requiring specialist knowledge

Properties in Morwenstow face several common issues that our RICS Level 3 Survey specifically targets. The age of much of the housing stock means that timber decay, including rot and woodworm, is frequently encountered. Traditional Cornish buildings often incorporate oak and elm timbers that, while durable, can suffer from fungal decay if moisture ingress has occurred. Our surveyors are trained to identify the early signs of timber problems, even where they may be hidden behind plaster finishes or flooring. We use moisture meters and probe timber where appropriate to assess the extent of any decay.

The render systems used on many traditional properties in the Morwenstow area can be vulnerable to damp penetration, particularly in exposed coastal positions. Salt-laden air accelerates the degradation of porous renders, and freeze-thaw cycles during winter months can cause surface deterioration. We assess render condition comprehensively, noting any cracks, delamination, or signs of moisture penetration that could indicate underlying problems. In severe cases, render failure can allow water ingress that damages the structural walling behind.

Wall tie corrosion is another significant concern in properties built between the 1920s and 1980s, where steel ties were commonly used to connect cavity walls. In coastal areas like Morwenstow, the salt air can accelerate corrosion of these ties, leading to structural concerns if left unchecked. Our Level 3 Survey specifically examines external walls for signs of wall tie failure, including bulging, cracking, or mortar degradation. The report will flag any concerns and recommend appropriate specialist inspection if necessary. This is particularly important for properties that may have had cavity wall insulation installed, which can sometimes exacerbate tie corrosion issues.

Given the rural nature of Morwenstow and the age of many properties, we also pay attention to septic tank and drainage arrangements, which may not meet current regulations. We note the location of fuel oil tanks, which are common in off-gas areas, and check for signs of contamination or inadequate containment. These are practical concerns that can represent significant expenditure for buyers.

While Morwenstow remains a rural parish with limited new build development, planning applications indicate some ongoing residential activity that may be of interest to buyers. A phased residential development of four dwellings at Land West of Woodridge, Woolley (EX23 9PL) has been approved, representing a modest addition to the local housing stock. Additionally, an application for Permission in Principle for the construction of five dwellings within the parish was under consideration. For buyers interested in newer properties, these developments offer alternatives to the predominantly period housing stock.

For properties that have been recently constructed or significantly renovated, our Level 3 Survey can verify the quality of workmanship and identify any potential building regulation compliance issues. We check that materials and installations meet current standards and that any extensions or alterations appear to have been properly carried out. Given the limited availability of larger development sites in Morwenstow, many properties may involve conversions of agricultural buildings, which present their own specific considerations including potential contamination from previous agricultural use.

The agricultural character of the parish means that some residential properties may have been converted from barns, shippons, or other farm buildings. These conversions can present unique issues, including original structural elements that may have been designed for agricultural rather than residential use. Our surveyors are experienced in assessing converted buildings and can identify where original features may require attention or where insulation and ventilation may be inadequate for modern living standards.
