Party Wall Act – Do You Really Need to Serve Notice?
Following the recent Court of Appeal decision of Power & Kyson v Shah (2023), it is now the case that the PWA cannot apply unless and until a valid Notice has been served. The requirement for Notices to be served in appropriate cases remains, but if that is not...
Is it always necessary to issue a Party Wall Notice, when the Party Wall Act says so?
In a word - no. “De minimis” is a legal principle which allows for matters that are small scale or of insufficient importance to be exempted from a rule or requirement. It can be used by the courts as an exclusionary tool to dismiss trivial matters from litigation. It...
Ground-Shifting Changes in How We Tackle Subsidence
The UK’s clay subsidence industry was born in the 1970s, matured in the 1980s and fuelled by global-warming has since grown to become a huge behemoth which already costs the insurance industry millions every year – predicted by PwC to increase by 800% and cost £1.9 billion per year in the not too distant future, if climate change continues.
Something has to change soon – and it can;
Crack Diagnosis – cracks tell a story
The diagnostic art of identifying different types of building movement from crack patters is a skill which takes many years of practical experience to learn properly. I have heard many cases where clients have been told by tradesmen visiting the house, or over the...
UK Geology – and root-induced subsidence (part 2 – Mudstone)
Root-induced subsidence occurs in shrinkable soils, which are mainly clays, or clay-based matrixes. In the UK there are a great deal of different soil types, and layers of differing soils. We need to differentiate between bedrock (i.e. the main older ground type...
Clay Subsidence; Building standards & defective (or inadequate) design (or construction)
In the UK we have rigorous standards for construction. The Building Research Establishment first published guidance for building near trees on clay soils in 1949 – then just an approximate rule of thumb that houses should not be sited closer to a tree than its mature...
Who should I use to handle my subsidence problem?
Insurer-employed vs independent subsidence consultants When you have subsidence, it needs to be handled carefully and properly, by an experienced consultant. Adequate and appropriate investigations need to be undertaken not only to correctly diagnose the precise...
UK Geology – and root-induced subsidence (part 1 – London clay)
Root-induced subsidence occurs in shrinkable soils, which are mainly clays, or clay-based matrixes. In the UK there are a great deal of different soil types, and layers of differing soils. We need to differentiate between bedrock (i.e. the main older ground type...
Is the UK out of step with the rest of the world on subsidence?
Basically, yes! In most other countries, they view cracking to buildings much differently, more like how we would view any other minor building defect. The vast majority of subsidence cracks are minor and not structurally threatening and subsidence is generally not...
When street trees cause subsidence
Everybody likes a tree-lined avenue and street trees are important for several environmental reasons such as air quality as well as their aesthetic value. Local authorities want to keep street trees wherever possible, but in many cases on shrinkable clay subsoils,...
