Consulting structural and civil engineers, based in north-west London
Green Code Engineering inspects, designs and details structure for homeowners, architects, builders and developers. Most of our work is in London’s existing houses and flats, where every job starts with understanding a building someone else built a hundred years ago.
What we are here to do
People usually come to us at one of two moments: something has gone wrong with a building, or they are about to change one. A crack has appeared, a buyer’s survey has raised a question, or there is a wall to take out, a loft to convert or a basement to dig.
Our job is to find out what the structure is doing, explain it in plain English and give you drawings and calculations prepared for Building Control submission, with their technical queries answered, that a builder can price and build from. We then stay involved through construction when you need us.
How we work
A fixed fee in writing first
We confirm the scope and one fixed fee before any work starts, so you know the cost of the engineering from day one.
Start from the real building
We inspect, measure and where needed open up the structure, using Matterport, laser scanning and drones, rather than design from assumptions.
Drawings people can build from
Calculations and drawings are issued ready for Building Control, party wall surveyors and your builder, and we answer their questions.
On site when it matters
Inspections during construction, revisions when the builder finds something unexpected, and sign-off at the end.
Who we work with
- Homeowners planning an extension, loft or alteration, or worried about cracks or movement
- Buyers, sellers and lenders who need a structural inspection or building survey
- Architects and designers who need a structural engineer from planning to construction
- Builders and contractors who need calculations, temporary works or a quick answer on site
- Developers and landlords with new-build apartment blocks, mixed-use buildings up to 15 metres, HMO and change-of-use schemes
- Commercial occupiers and colleges altering or loading existing buildings
Where we work
Most of our projects are in Greater London, across 299 postcode districts, with work in 50 towns beyond, from the home counties to Milton Keynes and the North West.
We never publish client names or addresses. Every project on this site is shown by area only.
