Structural Engineers in Solihull
Residential structural engineering that doesn't leave you guessing
Extension and renovation beam design in Solihull. Contact PorthouseDean Structural Engineers today to get your calculations sorted.
We know Solihull's housing stock and what Solihull Metropolitan Borough Council expects
Offices in Manchester, London and Gloucester, with engineers around the country for site visits. We've worked extensively across West Midlands and know Solihull well — the Post-war suburbs → modern Brick semis, dormer bungalows, the party wall situations that come with them.
More importantly, we know how Solihull Metropolitan Borough 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 for extensions, knock-throughs, loft conversions, and two-storey extensions in Solihull. With 160+ calculations completed across West Midlands, our engineers understand the area's Post-war suburbs → modern Brick semis, dormer bungalows properties, ensuring every design accounts for local building characteristics and Mercia Mudstone ground conditions. Our most recent project in the area was a single storey extension completed in Dec 2025.
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 160+ 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 160+ projects across West Midlands, structural calculations typically start from £500 + VAT depending on complexity.
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.
