A Level 3 Building (Structural) Survey is the most detailed residential property inspection available, meticulously designed to provide a thorough understanding of a property's condition before you commit to the purchase.
Whether you're buying an older home, a property that has been altered or extended, or simply want complete peace of mind, this comprehensive survey provides the detailed insight needed to make informed decisions and avoid unexpected costs.
At CharterHouse Surveyors & Engineers, these bespoke, property-specific reports significantly exceed the minimum requirements of a standard RICS Level 3 Building Survey. They provide clear explanations, practical advice and professional recommendations that help you understand not only what defects exist, but why they've occurred, what the implications are, and how they should be addressed.
What distinguishes our service is the genuinely multidisciplinary expertise that we offer. Our team consists of Chartered Building Engineers and Architectural Technologists alongside Building Surveyors. This breadth of knowledge ensures a comprehensive understanding of construction, defect development, and appropriate remedial solutions – our inspections are never subcontracted to third parties or conducted by trainees.
The dedicated professional who inspects your property will prepare your tailored report and remain directly available to discuss the findings, ensuring you receive the highest level of due diligence and support.
The reports also feature dedicated sections on structural movement, dampness, condensation and timber defects alongside a prioritised defect schedule to help you quickly identify urgent repairs and plan future expenditure with absolute confidence.

Eligibility criteria and the defect framework

Property Suitability and Eligibility Criteria
Our Level 3 Building (Structural) Survey is our most detailed residential inspection and is suitable for any residential property type. It is specifically designed and highly recommended for older or period properties, listed and historic buildings, and properties built using non-traditional construction methods.
This comprehensive assessment is also essential for larger or unusual homes, buildings that are in a poor or uncertain condition, or properties displaying clear physical signs of distress such as structural cracking, movement, or dampness.
Furthermore, it is the ideal choice if you are purchasing a home that has been significantly altered, extended, or requires extensive renovation and modernisation, providing the highest level of due diligence and complete peace of mind

The Defect Explanation Framework
We believe a property survey should do far more than simply list symptoms, which is why our bespoke reports go deep into building physics to explain exactly how your property is performing.
Where specific defects are identified during our comprehensive visual inspection, we apply a rigorous five-step diagnostic framework to give you complete clarity. For every single issue uncovered, our tailored reports clearly explain the exact nature and severity of the defect, its likely underlying cause, and the potential consequences to the property if the issue is left unresolved.
To help you move forward with absolute confidence, we then provide practical, honest recommendations for repair or further investigation, alongside an assessment of the likely impact on your future maintenance and ownership costs
