RICS Level 3 Building Survey in Snowshill

The architecture of Snowshill is dominated by traditional Cotswold stone construction, with buildings featuring locally quarried limestone walls, stone slate roofs, and mullioned windows characteristic of the region. Properties dating from the 17th century often have solid stone walls, timber roof structures, and lime-based mortars and renders that behave differently from modern construction materials. A Level 3 Survey provides the detailed analysis needed to understand how these traditional elements are performing and whether they require ongoing maintenance or urgent repair. Our inspectors understand the specific characteristics of Cotswold stone and can identify defects that are common to this type of historic construction.

Approximately 25% of Snowshill's properties are listed buildings, meaning they hold special historic or architectural significance and are protected by strict preservation regulations. Snowshill Manor, the village's only Grade II* listed building, sits within Grade II registered gardens and is now managed by the National Trust as a visitor attraction. Any work to listed properties requires Listed Building Consent, and our surveyors understand these constraints, flagging any issues that might involve regulatory implications or require specialist restoration expertise. We assess whether previous owners have carried out alterations that may require retrospective consent.

The village's position on the Cotswold hills means properties can be affected by ground conditions that are less common in lowland areas. While Snowshill sits on limestone bedrock from the area's historic quarries, underlying clay soils in parts of the Cotswolds can cause shrink-swell movement, particularly where mature trees are present. Our surveyors assess foundations carefully and look for signs of movement or subsidence that might indicate ground instability, which is particularly important given the age of many properties in the village.

Many properties in Snowshill are used as second homes or holiday lets, meaning they may be vacant for extended periods throughout the year. This can lead to a lack of regular maintenance and potential deterioration that goes unnoticed until a purchase survey is carried out. Our inspectors specifically look for signs of neglect, water damage from plumbing leaks, and issues arising from inadequate heating or ventilation during vacant periods. These issues can be particularly costly to remediate if they have been allowed to develop over several seasons.

Properties in Snowshill face several recurring issues that our surveyors regularly identify during inspections. The age of the housing stock means that timber decay, including both rot and woodworm infestation, is frequently found in roof structures and floor joists. Stone slate roofs, while durable, require robust supporting structures, and individual slates can slip or become damaged over time, leading to water ingress that may not be immediately visible from inside the property. Our inspectors specifically examine roof spaces where accessible, looking for signs of past water penetration and structural stress to timber members.

Damp is a common concern in traditional Cotswold cottages, particularly where modern alterations have been carried out inappropriately. The introduction of uPVC windows, cement-based renders, or non-breathable insulation can trap moisture within solid stone walls, causing damp problems and accelerating stone decay. Our surveyors are trained to identify these issues and assess whether recent improvements might actually be causing harm to the historic fabric. We look for signs of rising damp, penetrating damp, and condensation problems that may not be apparent during a brief viewing.

The local geology and soil conditions can also affect properties in the area. Snowshill's name itself derives from old English meaning "Hill of Snow," and it is often said that snow remains in the folds of the hill long after it has melted in the Vale below, suggesting specific topographical and geological conditions. While the underlying limestone bedrock provides generally solid foundations, areas with clay subsoil can experience shrink-swell movement during wet and dry cycles. This is particularly relevant where mature trees are present near foundations, as tree roots can both extract moisture from clay soils and physically disrupt foundations.

The recent introduction of the Article 4 Direction in October 2025 has highlighted concerns about inappropriate modern alterations to historic properties. Our surveyors commonly find uPVC windows, black plastic front doors, and inexpensive fencing that have been installed without planning permission. While these may seem minor, they can cause significant problems in traditionally constructed buildings by trapping moisture and preventing breathability, leading to accelerated decay of stonework and timber. We document any non-compliant alterations and advise on options for sympathetic replacement.

• Foundation movement in clay soils
• Non-compliant conservation alterations

Understanding the traditional construction methods used in Snowshill is essential for assessing the condition of any property in the village. The predominant building material is locally quarried Cotswold limestone, which has been used for both walls and roofing for centuries. This stone is characterised by its warm golden colour and relatively soft nature when first quarried, which hardens over time. The stone was traditionally worked by hand and laid in random rubble courses, creating the distinctive irregular wall surfaces that define the village's character.

Stone slate roofs are another defining feature of Snowshill architecture. These heavy roofing materials require substantial timber rafters and purlins to support their weight. Our surveyors examine these roof structures carefully, as the combination of age, weight, and potential past overloading can lead to structural issues. The stone slates themselves are prone to slipping, breaking, or becoming displaced over time, and we check for signs of past repairs using inappropriate materials that may have caused additional problems.

Traditional lime-based mortars and renders were used throughout the village's construction history, allowing buildings to breathe and moisture to evaporate from walls. Modern cement-based products, by contrast, trap moisture and can cause significant damage to historic fabric. Our inspectors are trained to identify where inappropriate modern materials have been used and to assess the extent of any resulting damage. This is particularly important for properties that may have been "improved" without understanding the consequences for traditional construction.

Windows in Snowshill properties typically feature stone mullions, often with leaded light or casement windows behind. These historic windows are an important part of the building's character and are specifically protected under conservation regulations. Our surveyors assess the condition of these features, checking for decay to timber frames, damage to stone mullions, and the condition of any leaded lights. We also identify where windows may have been replaced with inappropriate modern alternatives that could affect both the building's character and its weather resistance.
