A home buyer’s structural building survey is the most wide-ranging inspection of a property, providing a comprehensive evaluation of the property’s condition.

Do I Need a Structural Building Survey?

If you are planning on buying a new-build property (i.e. one that’s been built in the last 10 years) then it should still be covered by warranty or guarantee.  You will normally only need to consider a structural building survey if the property appears to be in a poor state of repair.

However, if one of the following applies, you should contemplate instructing a structural building survey:

·         The building obviously needs structural work, is in a poor state of repair or a run-down state;

·         The property is of an unusual construction (e.g. is thatched or has a timber frame);

·         The building is over three storeys in height;

·         The property is over 50 years old;

·         You intend to carry out major alterations, such as converting or adding an extension.


If any of these apply, you should consider contacting Crownstone on 0207 226 5654; one of our friendly team will be able to advise you on whether a structural building survey meets your specific needs.

The Benefits of a Structural Building Survey

As structural building surveyors, acting on your behalf, Crownstone will provide you with a comprehensive final report.  Not only does your report details any problems and/or concerns pinpointed during the survey but it will also give an indication of the likely costs of any remedial works required, leaving you, the customer, knowing exactly where you stand.

In the worst-case scenario, you may decide not to purchase a property if the structural building survey reveals excessive works.  Equally, where fixes are more manageable, our structural building surveys will equip you with all the relevant information needed to negotiate a fair price with your seller.

Basement Impact Assessments

What is Basement Impact Assessment?

A basement impact assessment (BIA) is a process of incorporating a combination of surface and groundwater hydrological conditions, with geotechnical analysis into a comprehensive review. The objective is to establish the risk of ground movements arising from the basement development and any impact on adjoining or neighbouring properties and the potential flooding risk.

Do I Need a Basement Impact Assessment?

When submitting applications for basement developments, the level of technical information required for a basement impact assessment (BIA) will vary according to the type and size of the development, as well as the borough, district or area in which it is located.  This is particularly true of certain areas in London, where a BIA is a compulsory requirement of planning authorities.


To find out if you need a Basement Impact call us on 0208 226 5654 or contact us using the online form at the bottom of this page.


What Can I Expect from my Basement Impact Assessment?

A basement impact assessment (BIA) should be specific to the site and the particular development proposed. Through collation of information and detailed analysis the BIA sets out to evaluate the direct and indirect implications of a proposed development.

BIAs normally comprise both a factual report and an interpretive report. The interpretive report is usually split into sections such as the following:

§  Site history, underlying geology and groundwater.

§  The impact of the subterranean development on drainagesewagesurface water and ground water flows and levels.

§  Ground movement due to the proposed development (including demolition of any existing structures) and corresponding damage to neighbouring properties and infrastructure.

Although there is no standard template for the contents of a BIA, some councils will publish their own and encourage applicants to use their templates when making planning applications, so that their review process can be more easily standardised.

Whatever the requirements of your project and planning authority, our Chartered Surveyors will be there to guide you through, producing a fully informed and informative Basement Impact Assessment and ensuring you meet your responsibilities at every stage of the design and build process.

Flat Roof Surveys

Do you own a residential or commercial property in London and are anxious about the state of your flat roof?  Have you noticed tell-tale damp marks or dripping water inside which suggests that your roof might be compromised?
