RICS Level 3 Building Survey in Collier Street

Collier Street's property market is characterised by high-value period properties that command significant investment from buyers. The village has seen property prices rise dramatically, with recent sales achieving prices 40% above the 2023 peak. This premium market attracts buyers seeking character homes, but older properties often conceal defects that only a detailed structural survey can reveal. The village has seen particular interest from buyers looking to escape urban areas while maintaining commutable distances to London, driving demand for the unique character properties available here.

The presence of 17th-century Grade II listed buildings such as Chequer Tree Farmhouse demonstrates the architectural heritage found throughout this area. While these properties are highly desirable, they also require careful inspection by surveyors who understand traditional building materials and construction methods. Our RICS Level 3 surveys examine every accessible element of the property, from the roof structure to the foundations, providing you with a complete picture of the building's condition. We understand that buying a listed property comes with additional responsibilities, and our reports include guidance on maintenance approaches that will preserve the building's character while addressing any structural concerns.

Properties of this age were constructed using techniques and materials that differ significantly from modern building practices. Lime mortar, oak framing, and traditional roof coverings all have specific maintenance requirements and potential failure points that our inspectors know to look for. A Level 3 survey will identify any existing defects, potential future problems, and provide recommendations for ongoing maintenance that can save you substantial sums in the long run. Our surveyors have inspected numerous properties in the surrounding villages including Yalding, Marden, and Paddock Wood, giving us particular insight into the construction types common to this part of Kent.

The Kentish Weald region, where Collier Street is situated, has a long history of agricultural buildings being converted into residential properties. These conversions often present unique challenges, as the original barn or oast house design may not have been intended for domestic use. Our surveys carefully assess whether such conversions have been properly undertaken, checking that the necessary planning and building regulation approvals were obtained and that the work is of an acceptable standard. This is particularly important in the Collier Street area where such conversions are common.

The housing stock in Collier Street predominantly consists of period properties built using traditional Kentish building methods. Many of the older houses in the area were constructed with solid brick walls, typically 9 inches thick or more, which were built without the cavity spaces found in modern construction. Understanding this is essential because solid walls are more susceptible to damp penetration and require specific treatment approaches. Our surveyors know to check the condition of these walls carefully, looking for signs of damp, salt migration, and deterioration of the mortar joints.

Timber framing is another common feature in older Collier Street properties, particularly in buildings dating from the 17th and 18th centuries. These properties often have visible oak beams and joists, which can be both a desirable feature and a potential concern if they have been affected by wood-boring insects or fungal decay. Our inspectors carefully probe accessible timber to assess its condition, looking for signs of active beetle infestation or rot that could compromise structural integrity. We also check for any previous timber treatment and assess whether the current condition is stable or requires ongoing monitoring.

The roofs on period properties in this area were traditionally constructed with heavy clay or slate tiles fixed to timber rafters. Over time, the weight of these tiles can cause deflection in the roof structure, and our surveyors assess whether the rafters and purlins show any signs of stress. We also examine the condition of the tile hangs and check for any slipped or missing tiles that could allow water ingress. Given the age of many properties in Collier Street, we pay particular attention to the condition of lead flashing and valley gutters, which are common failure points on older roofs.

Many properties in the Collier Street area have been extended over the years, sometimes with varying degrees of craftsmanship and adherence to building regulations. Our Level 3 surveys include a thorough assessment of all extensions and alterations, checking that they were constructed properly and that the junction between old and new work is weathertight. We also verify where possible that any listed building consents were obtained for alterations to historic properties, as this can have significant implications for future owners.

The RICS Level 3 Survey is the most comprehensive inspection option available and is specifically recommended for properties in excess of 75 square metres, buildings of non-traditional construction, and any property that has been significantly altered or extended. In Collier Street, where many properties date back centuries, this level of detail is essential for making an informed purchasing decision. The thorough nature of the Level 3 survey means it is particularly suitable for the high-value period properties that dominate this village, where the cost of unidentified defects can be substantial.

Our surveyors examine the property's structure including walls, floors, ceilings, and roof framework. We assess the condition of the building fabric, identify any signs of movement or structural stress, and evaluate the condition of all visible damp proofing and insulation. The report includes detailed photographs showing specific defects, explanation of their likely cause, and recommendations for remedial work where necessary. We use standardised defect categories that make it easy to prioritise the work required, categorising issues as urgent, important, or requiring future monitoring.

For listed buildings in the Collier Street area, our surveyors understand the additional considerations that apply. We can advise on the condition of historic features, identify any previous unsympathetic alterations, and provide guidance on maintenance approaches that will preserve the building's character while addressing structural issues. This expertise is invaluable when purchasing a property with listed status, as future works may require listed building consent. Our surveyors are familiar with the requirements of both Grade II and Grade II* listed buildings and can advise on the implications of various forms of deterioration.

The Level 3 survey also includes an assessment of the property's energy efficiency and the condition of its building services. While this is not as detailed as a full Energy Performance Certificate, it provides useful guidance on the general thermal efficiency of the property and identifies any obvious issues with the heating system, plumbing, and electrical installation. This is particularly relevant for older properties in Collier Street, where the original building services may have been updated piecemeal over the years and may not meet current standards.
