We know Trafford's housing stock and what Trafford Council expects

Offices in Manchester, London and Gloucester, with engineers around the country for site visits. We've worked extensively across Greater Manchester and know Trafford well — the Post-war suburbs → regeneration Brick semis, modern flats, the party wall situations that come with them.

More importantly, we know how Trafford Council’s building control team operates and we write our calculations to match. That saves time on site and avoids queries coming back.

Projects completed across Trafford and surrounding areas
Familiar with Glacial clay ground conditions and what that means for your foundations
Experience with Post-war suburbs → regeneration properties and the structural challenges they present

Site visits arranged locally when your project needs one

With 1,000+ calculations completed across Greater Manchester, our engineers understand the area's Post-war suburbs → regeneration Brick semis, modern flats properties, ensuring every design accounts for local building characteristics and Glacial clay ground conditions. Our most recent project in the area was a single storey extension completed in Jan 2026.

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 1,000+ 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

★★★★★
I've used PorthouseDean engineers for many of our clients and my personal project. I find their pricing fair to reflect the quality work that has been produced. Definitely recommend.
— Clinton Johnson · Trustpilot
★★★★★
I was referred to them by the building control designers. I found them responsive and helpful. The engineering came through quickly for building control and as I needed them to get contractors quotes. Fair and reasonable price for the excellent service.
— Oasis · Trustpilot
★★★★★
The internal structural walls changed at least 3 times and the engineer assigned to me was very accommodating with the changes. I liked the fact that the work they do is peer-checked. Would not hesitate to use them again.
— Phil Neo · Trustpilot

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.

Having completed 1,000+ projects across Greater Manchester, we can confirm structural calculations typically start from £500 + VAT.

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.
