Structural Calculations in Maidstone
Structural calculations are the engineering sign-off needed whenever a project alters or removes a load-bearing element — a steel beam over a knocked-through wall, a new foundation for an extension, or a strengthened floor for a loft conversion — set out in a structural drawing and calculation pack that Building Control checks the work against.
In Maidstone, that covers Allington, Barming, Loose, Penenden Heath, Tovil, Weavering, Bearsted. Maidstone is the county town of Kent, set on the River Medway, with a historic centre and a broad mix of Victorian terraces, interwar suburbs and newer estate development across the wider town and surrounding villages.

Property styles in Maidstone
The town includes Victorian and Edwardian terraces close to the centre, substantial interwar semis in the surrounding suburbs, and more recent estate housing on the town's edges, alongside period cottages in the outlying villages.
Planning considerations
Maidstone Borough Council is the local planning authority. The historic town centre and several village centres in the borough are conservation areas, and some areas are at risk of flooding from the River Medway, which can affect ground floor extension and conversion design.
How it works
Our structural calculations process
- 01
Site survey
Assessing the existing structure — what it is, what condition it's in, and what the proposed works need it to do.
- 02
Structural design
Sizing the beams, foundations or floor strengthening needed, coordinated with the architectural drawings where we're producing both.
- 03
Calculations pack
Preparing the formal calculation pack and structural drawings in the format Building Control and the wider design team need.
- 04
Building Control liaison
Submitting calculations to Building Control and handling any follow-up queries through to approval.
- 05
Construction support
Available through the build for any site queries as the structural work is carried out.

FAQs
Structural Calculations in Maidstone: FAQs
Do you provide structural calculations across all of Maidstone?
Yes, we cover the ME14, ME15 and ME16 postcode areas in full, including Allington, Barming, Loose, Penenden Heath, Tovil, Weavering, Bearsted.
Do I need structural calculations for a loft conversion?
Almost always — the existing floor typically needs strengthening to take habitable-room loading, and any new stair opening or dormer usually needs its own structural design. Building Control will check the work against a calculation pack as part of sign-off.
Can you provide calculations for a beam I've already had designed elsewhere?
We generally produce calculations as part of a coherent structural design for the whole project, but get in touch with what you have and we'll advise whether we can work from it or whether it needs revisiting.
Does flood risk from the River Medway affect extensions in Maidstone?
For properties in flood risk areas, extension design may need to take flood resilience into account, and a flood risk assessment can be required as part of a planning application. We check the Environment Agency flood mapping for your property during feasibility.
