RICS Level 3 Building Survey in AB15

As the most comprehensive structural inspection available for residential properties, the Level 3 covers every accessible element of the building using a three-tier condition rating: condition 1 (no repair needed), condition 2 (monitor and plan), and condition 3 (urgent repair or specialist investigation required). The written report is produced in plain language, with a clear priority list and a maintenance schedule for lower-urgency items.

• Structural frame, foundations, and any evidence of movement or settlement
• All external walls, granite masonry condition, pointing, and render
• Roof structure, coverings, ridge and hip details, and all rainwater drainage
• Internal floors - suspended timber, concrete, and any screeds
• All dampness and moisture issues, including penetrating, rising, and condensation
• Electrical, gas, and plumbing installations (inspected visually, not tested)
• All extensions, conversions, and structural alterations
• RAAC risk assessment for applicable property ages
• Flood risk and any evidence of historical flood damage
• Legal and planning considerations including conservation area designations and Article 4 Directions

For properties in Rubislaw and surrounding conservation areas, the report specifically addresses the Article 4 Directions in force, which mean that alterations to windows, doors, rooflines, and external cladding require planning permission rather than being permitted development. Buyers who plan to renovate or alter a property in these areas need this information before they exchange contracts.

Where items cannot be fully assessed during the inspection - for example, where subfloor access is restricted or roof spaces are not safely accessible - the report identifies these limitations and recommends specialist investigation. Specialist referrals for RAAC assessment, timber and damp investigation, or structural engineering are included in the report where the inspection findings suggest these are needed.

Across the range of property types in AB15, these are the defect categories most frequently identified in Level 3 reports. The specific distribution of findings varies considerably between the Victorian granite stock in Cults and Rubislaw, the mid-century housing in other parts of AB15, and the newer developments at Countesswells.

Roofing defects account for a significant proportion of condition 3 items in older AB15 properties. Natural slate deteriorates over time, with individual slates cracking, slipping, and loosening at the nibs. Lead valleys and flashings around chimney stacks and dormers fail progressively, allowing water ingress to roof voids and internal ceilings before the defect is visible externally. Cast-iron guttering on Victorian properties corrodes at joints and pull-out fixings, causing localised water damage to wall faces below.

Timber deterioration is consistently identified in pre-1960 properties across AB15. Suspended timber ground floors are susceptible to wet rot and dry rot where subfloor ventilation has been reduced or where drainage issues have allowed persistent moisture. Dry rot in particular can spread through wall fabric and require extensive treatment and replacement of affected timbers. All accessible timber conditions are recorded in the report, with specialist investigation recommended where active decay is suspected.

Settlement and structural movement is more varied across AB15 than in the granite-bedrock areas of central Aberdeen. Subsidence issues have led to demolition of residential blocks at Erroll Place and Erroll Street in Aberdeen - built on unstable ground over a gravel pit. Clay shrink-swell risk, particularly in areas with significant tree coverage, and the potential for ground movement from historical mineral exploration in Aberdeenshire are factors that the Level 3 survey addresses in its structural assessment.

In the Countesswells new-build developments, the more common issues relate to construction quality rather than age-related deterioration. Foundation settlement, waterproofing defects, insulation and ventilation problems leading to condensation, and workmanship issues on finishing and external elements are typical findings in properties a few years old. For these properties, a snagging inspection during the developer liability period is the appropriate first step, with a full Level 3 recommended if significant defects are found.

Prices for Level 3 Building Surveys in the Aberdeen area start from £619, with costs increasing based on the property size, age, and complexity of the inspection. For the larger granite villas typical of Rubislaw and Bieldside - with their multiple floors, outbuildings, and complex roof arrangements - fees are higher than for a standard two-bedroom semi-detached. Listed buildings and properties with known structural issues attract additional time charges given the depth of investigation required.

The national range for Level 3 surveys runs from £600 to more than £1,500, with properties above £500,000 in value typically attracting fees of £850 and above. Given that AB15 detached properties average £433,817 and a 5-bedroom home in the postcode can reach £621,000 (Hutch data), the survey fee represents a proportionately small cost against the total purchase. For buyers at the upper end of the AB15 market, the Level 3 report provides both the structural assessment needed before exchange and a valuable maintenance reference document for the years ahead.

Fixed prices are confirmed before you book. No surcharges are added after the inspection, and the report is delivered within five working days. We are also available to discuss findings with you after delivery, including guidance on using the report to negotiate on price where significant condition 3 items are identified.
