Structural Engineers Christchurch
Extending, altering, or worried about an older Christchurch building? We've got you covered.
What We Help With
Christchurch projects often involve older houses, converted flats or additions made in stages. Before you open up a room, alter a roof or act on a surveyor’s comment, we check how the existing building carries its loads.
We focus the design on the change you are making and the parts of the building it affects.
- Alterations to older masonry homes
- Structural design for extensions and lofts
- Reports on cracking and movement

What We Need From You
Send the address, photographs and any plans you have. If the building is listed, in a conservation area or close to the river, include the planning information so we can identify the constraints early.
For a flat, send the leaseholder or freeholder requirements as well as the drawings.
- Clear photographs of the concern and the rooms around it
- Existing and proposed plans
- Surveyor reports, previous approvals or records of earlier work

Site Visits
We visit where the age, layout or history of the building makes photographs unreliable. In Christchurch, that is common where old extensions meet the original house, where floors have been altered, or where structure is shared between flats.
A site visit lets us trace the load path through the actual building.
- Older central properties and converted flats
- Homes with visible movement or uneven floors
- Projects where roof, floor and wall changes interact
What You Receive
For building work, you receive calculations and drawings that show the builder what has to support what. For a concern about condition, you receive a report explaining the evidence, likely cause and next step.
We write the information around your property rather than copying a standard detail into every job.
- Beam, bearing and foundation details where needed
- Drawings for the builder and Building Control
- A clear report or monitoring advice for movement

Building Control Approval in Christchurch
Structural alterations in Christchurch fall within the BCP Building Control area. We prepare the structural information for that route and answer questions that relate to our design.
If a project changes the outside of a listed building or a property in a conservation area, planning or listed-building consent can be a separate matter.

Listed and Conservation Area Buildings
Christchurch's town centre holds a genuine concentration of old and listed buildings, and that changes how a project runs.
- We check what's actually carrying load before designing anything into an old building
- Listed building consent runs alongside Building Control, and it's worth starting both early
- We aim to work with original fabric where it's sound, not replace it as a default
Properties Near the Stour and Avon
Parts of Christchurch, particularly near the quay and harbour, sit low enough that flooding is a genuine consideration.
- Flood risk affects foundation depth and floor levels for property in these areas
- Repeated wetting can affect timbers and wall bases in ways worth checking specifically
- Tell us your address early and we'll say plainly whether it's relevant to your project
