Structural Engineers in Northumberland
Residential structural engineering that doesn't leave you guessing
Structural support for renovations in Northumberland. Start your project the right way – get expert calculations from PorthouseDean
We know Northumberland's housing stock and what Northumberland County Council expects
Offices in Manchester, London and Gloucester, with engineers around the country for site visits. We've worked extensively across Northumberland — the Medieval → modern Stone cottages, brick semis, the party wall situations that come with them.
More importantly, we know how Northumberland County Council’s building control team operates and we write our calculations to match. That saves time on site and avoids queries coming back.
Local knowledge
PorthouseDean provides structural engineering services in Structural Engineers in Northumberland. With 9,000+ calculations completed across England, we bring proven expertise to every project.
Houses are all we do. That specialism matters when something goes awkward.
We don't do commercial. We don't do bridges. We do extensions, loft conversions, knockthroughs, new builds — and we've done over 9,000+ of them with a 100% building control success record.
That specialism means when your project throws up something unexpected — and they always do — we've seen it before. We know what works, what building control will push back on, and what your builder actually needs on the page to build from.
The quote's the easy part. It's three weeks later that matters.
The difference between structural engineers doesn't show up in a quote. It shows up when your builder's on site and something doesn't add up. When building control come back with a query. When the design changes halfway through and someone needs new calcs yesterday.
Our calculations are detailed enough that your builder can work from them without ringing anyone. When BC come back with a query, we deal with it — as many as they want. If they want something changed, we change it.
Project changes? Every quote includes a free amendment because we know designs evolve. Need to speak to your engineer? We give you a direct booking link for meetings, and our tech support team handles urgent queries whenever you need them.
A builder standing around waiting for a structural answer costs real money. We're the engineers who pick up the phone.
Fixed fee. No surprises after you've committed.
The number we quote is the number you pay. No extras bolted on for BC queries, no awkward invoice three months later.

What people say
Frequently Asked
If you're removing a wall, converting a loft, building an extension, or doing anything that affects the structure of your house — yes. Building control will require structural calculations before they sign off the work.
A virtual site visit is included in every quote — it's a chance to put a face to the name and talk through specific design requirements with your engineer. But we don't believe a physical visit is necessary for most residential projects. Working remotely allows us to be more economical while maintaining the same quality throughout. If your project does need a physical visit, we have engineers around the country who can arrange one.
Quote within 24 hours of receiving your plans — often much quicker. Standard delivery is 10 working days, but we can turn calculations around in as little as 1 working day if you need them urgently.
Based on our 9,000+ projects across England, structural calculations typically start from £500 + VAT depending on the complexity of the project.
Fees depend on the scope and complexity of your project. We provide clear, fixed-fee quotes within 24 hours so you know exactly what you'll pay before we start. No hidden costs, no extras for building control queries.
Every quote includes one free amendment because we know projects change — that's normal. Beyond that, we'll quote any further changes clearly so there are no surprises.
The quote's not the product — the project is. A cheaper set of calculations might get you through the door, but when building control query something or your builder can't follow the drawings, that's when it costs you. We include BC queries, an amendment, and a virtual site visit because that's where projects actually succeed or fail.
