RICS Level 3 Building Survey PO20 7

A RICS Level 3 Building Survey, formerly known as a Full Structural Survey, represents the most comprehensive inspection available for residential properties. Our inspectors spend several hours thoroughly examining the property, including all accessible areas such as the roof space, under-floor voids, and outbuildings. The survey provides a detailed assessment of the construction type, materials used, and overall structural integrity of the building. Unlike a basic condition report, the Level 3 survey gives you professional judgment on the building's future performance and any ongoing maintenance requirements.

For properties in PO20 7, our inspectors pay particular attention to the specific risks present in this coastal and rural area. The very high risk of clay shrink-swell subsidence means we carefully assess foundations, drainage, and any trees or vegetation close to the property that could affect soil moisture levels. We also examine properties for signs of coastal erosion impact, given the area's proximity to Chichester Harbour and the documented erosion rates of 0.1-0.2 metres per annum affecting local frontages. Our surveyors are familiar with the local geology and understand how the chalk substrate and clay deposits interact with the water table, particularly in lower-lying areas near the harbour.

The inspection covers all major structural elements and building systems. We assess the condition of load-bearing walls, floors, and ceilings, while also examining non-structural elements that might indicate underlying problems. Our report includes clear photographs of any defects found, severity ratings using the RICS traffic light system, and specific recommendations for repairs or further investigations. For properties in conservation areas or listed buildings, we provide guidance on any heritage considerations that might affect future renovation plans.

Properties in the PO20 7 area present unique challenges that make a RICS Level 3 Building Survey particularly valuable. The housing stock includes a mix of traditional period properties, many likely dating back to the Victorian and Edwardian eras, alongside more modern developments. The presence of listed buildings in Birdham and the surrounding Chichester Harbour Area of Outstanding Natural Beauty means many properties have specific construction characteristics and historical features that require expert assessment. Properties in this area were often built with traditional lime mortars and solid walls that behave differently from modern cavity wall construction, requiring specific expertise to assess their condition accurately.

The significant price growth in the area, with some sub-sectors showing increases of 38% compared to 2013 peaks, means the financial stakes are high for buyers. A comprehensive survey helps you avoid costly surprises by identifying issues before you commit to the purchase. In PO20 7JG, for example, average prices have reached £900,000, meaning a significant investment requires the protection that only a detailed Level 3 survey can provide. Properties in this area, particularly those near the marina or coastal locations, may also have been subject to specific building regulations and planning constraints that affect their current condition and future modification potential.

The Chichester Harbour Area of Outstanding Natural Beauty designation means many properties fall within conservation areas with strict planning controls. If you are considering purchasing a period property in Birdham or Itchenor, our survey report will highlight any issues that might affect your ability to obtain listed building consent for future alterations. We understand the local planning constraints imposed by Chichester District Council and can advise on the implications of any structural issues for potential renovation plans.

Our experience surveying properties throughout Birdham, Sidlesham, Itchenor, and the surrounding PO20 7 area reveals several recurring issues that buyers should be aware of. Given the local geology with very high shrink-swell clay risk, we frequently identify subsidence-related movement affecting foundations and structural walls. This is often exacerbated by mature trees close to properties, particularly in the more established residential areas around Birdham and along the lanes leading to the harbour. The British Geological Survey identifies this area as having significant clay shrink-swell potential, meaning foundation movement is a genuine concern for property buyers.

Coastal properties in the PO20 7 area face additional challenges from exposure to salt-laden air and moisture. We commonly find corrosion of metal fixtures, weathering of external renders, and deterioration of timber joinery. The age of many properties in the area also means inadequate ventilation is frequently identified, a particular concern where modern energy efficiency improvements have been made without adequate background ventilation, leading to condensation and potential timber decay. This is especially problematic in period properties where secondary glazing has been installed without considering the impact on air circulation.

Roof defects are another common finding, particularly on period properties where original roof coverings may be approaching the end of their serviceable life. We inspect for damaged tiles, deteriorated flashing at verges and ridges, and issues with flat roof sections that are particularly vulnerable in this coastal environment. The condition of chimney stacks is also carefully assessed, as these are often exposed to more severe weathering in coastal areas. Properties along the harbour front at Itchenor particularly suffer from accelerated weathering due to salt spray.

Drainage issues are prevalent throughout PO20 7, with many properties having aging drainage systems that were installed decades ago. We frequently identify cracked or displaced drains, inadequate falls, and connections to outdated septic tanks in rural properties. Given the clay soil conditions, any drainage defects can quickly lead to foundation movement, making this a particularly important area of the inspection. Our surveyors will also check surface water drainage away from the property, which is essential in this area where heavy rainfall combined with poor ground permeability can lead to surface water flooding.
