We Know Cornwall's Housing Stock and What Cornwall County Council expects
We have offices in London, Hertfordshire, Oxfordshire, and East Sussex, supported by engineers located across the UK who are available for site visits when required. Our team has extensive experience working throughout Cornwall, from historic properties and traditional brick semi-detached homes to timber-framed cottages and the party wall matters often associated with them.
Just as importantly, we understand the expectations and procedures of Cornwall’s building control team.
Our structural calculations and documentation are prepared to align with their requirements, helping reduce delays, minimise queries, and keep projects moving smoothly.
LOCAL KNOWLEDGE
-
Completed projects throughout Cornwall and nearby areas.
-
Strong understanding of local ground conditions, including Slate and Clay Loams Ground conditions, and how they influence foundation design.
-
Experience working with a wide range of properties, from historic buildings to modern homes, and the structural considerations they require.
-
Familiar with projects in and around Eden Project, and surrounding communities.
-
Local site visits available whenever an on-site assessment is required for your project.
Structural Engineering is What we do.
Our team works on a wide range of projects, from residential extensions and loft conversions to new builds, renovations, and complex structural alterations. With thousands of completed projects and a strong track record of building control approvals, we bring practical experience to every design we produce.
That experience matters when unexpected issues arise — and they often do in construction. Because we work across many types of engineering projects, we’re familiar with the challenges that can appear during design or on site.
We understand what solutions work, what building control will expect, and what builders need clearly shown in the drawings and calculations to move the project forward smoothly.
Getting a quote is the simple part. What really matters is the support that follows.
The real difference between structural engineers doesn’t appear in the initial quote — it shows up later, when construction is underway and questions arise. When something on site doesn’t quite line up. When building control requests clarification. Or when a design change requires updated calculations quickly.
Our calculations and drawings are prepared with enough detail for builders to work confidently from them. If building control raises a query, we handle it directly and provide the information required. And if adjustments are needed, we update the design to keep the project progressing smoothly.
Projects naturally evolve. That’s why our quotes include amendments when designs change. If you need to speak with an engineer, we offer direct meeting bookings, and our technical support team is available to respond to urgent questions when they come up.
When builders are waiting for structural guidance, delays cost time and money. We make sure you have the answers when you need them.
