Understanding Thurrock
Thames-side housing on clay soil
Properties across Thurrock — from Tilbury and Grays to Stanford-le-Hope and South Ockendon — sit predominantly on London Clay near the Thames estuary. This affects foundation design, drainage and how subsidence and heave should be assessed.
Mixed housing stock across the borough
Thurrock combines Victorian and Edwardian terraces in Grays, post-war and 1960s housing in Tilbury and South Ockendon, and substantial new-build developments around Purfleet. Each era has its own structural quirks worth understanding before alterations.
Active regeneration driving home improvements
Ongoing regeneration around Tilbury, Grays and Purfleet is increasing property values across Thurrock. Homeowners are investing in extensions, loft conversions, wall removals and structural surveys to bring older properties up to modern standards.
1950s-1970s residential housing stock near the Thames
Tilbury's housing is predominantly post-war terraced and semi-detached properties. Many homes are on clay soil near the Thames estuary, making foundation assessment important. Loft conversions and rear extensions are popular improvements.
What Homeowners & Contractors Say
"We had to regularise some structural work the previous owner had done without paperwork. SBS produced retrospective calculations and helped us get the Regularisation Certificate before completion."

Retrospective Calculations for Wall Removal - Thurrock
📍 thurrock · RM17
The Challenge
Owner of a Thurrock property had removed a load-bearing wall years earlier without Building Regulations approval. Wanted a Regularisation Certificate before listing the property for sale.
Our Solution
Carried out a site visit, measured the existing beam and supports, and produced retrospective structural calculations confirming adequacy. Submitted supporting documentation to Building Control on the homeowner's behalf.
The Result
Regularisation Certificate issued by Building Control. Property listed with clean documentation and sold to a buyer whose lender accepted the certificate without query.
