Tenterden's High Street conservation area is one of the largest in Kent, and a good number of the townhouses along East Cross and the High Street itself carry listed status. A concrete staircase inside a listed building is not automatically ruled out, but it needs listed building consent before any work starts, and the design has to respond to the historic fabric around it rather than simply dropping in a standard flight.
Where the property is a more recent build — the estates off Ashford Road and Beacon Oak Road are a common example — the process is more straightforward and follows the usual formwork, reinforcement and pour sequence without a heritage layer to navigate.
Listed building consent on High Street and East Cross properties
Any structural alteration inside a listed building, including forming a new stairwell or replacing an existing staircase with a concrete one, needs listed building consent from Ashford Borough Council, separate from and in addition to any Building Regulations approval. The application needs to address how the new stair relates to the historic plan form of the building, and a conservation officer will usually want to see how existing joinery, skirtings and wall finishes around the opening are protected or reinstated.
We prepare the supporting information for these applications as part of the design process, because a badly evidenced application is the single biggest cause of delay on listed projects in this town.
Working within an existing timber-framed structure
Many of the older Tenterden buildings are timber-framed behind their weatherboarded or brick-faced elevations, and a new concrete stairwell opening has to be checked against the frame layout before any structural opening is cut. Loading a concrete stair against an old timber frame also needs isolating correctly, since timber frames move seasonally in a way that a rigid concrete structure does not, and the junction between the two needs a detail that tolerates that difference in movement.
On newer estate properties this consideration doesn't apply, and the stairwell can be formed and loaded in the standard way against masonry or blockwork.
Access for concrete delivery on East Cross and the High Street
East Cross and the High Street carry restrictions on loading and can be busy with through traffic, so a concrete pump or mixer delivery needs a booked slot and, in some cases, temporary traffic management agreed with the council in advance. Properties set back from the road with rear access via a yard or lane are more straightforward, but access should still be surveyed before quoting rather than assumed from a street view.
On the newer estate roads off Ashford Road, standard wagon access is generally available without special arrangement.
Matching the stair to the building's character
In a period property, a board-marked or lime-washed concrete finish sits more comfortably alongside historic joinery than a heavily polished, glossy surface, and we discuss this with the client and, where relevant, the conservation officer before committing to a finish. Handrail and balustrade detailing also needs to reference the building's existing joinery style rather than defaulting to a generic modern rail.
On contemporary builds there's more freedom, and a polished or pigmented finish that ties into the rest of the interior specification is usually the better fit.
Structural sign-off and Building Regulations
Regardless of listed status, the finished staircase has to meet Building Regulations requirements for pitch, going, rise and headroom, and building control inspection is required at the reinforcement stage before the pour and again once the flight is complete. On listed buildings, the structural engineer's design also needs to reflect any constraints agreed through the consent process, such as limits on cutting into historic floor joists or wall plates.
We coordinate building control and, where applicable, the conservation officer so inspections happen at the right stages rather than being requested retrospectively.
Common questions
Do I need listed building consent for a concrete staircase in a Tenterden listed property?+
Yes. Any structural alteration inside a listed building, including a new or replacement staircase, needs listed building consent from Ashford Borough Council before work starts, in addition to Building Regulations approval.
Can a concrete stair be built against a timber-framed wall?+
Yes, but the junction needs isolating so the rigid concrete structure and the seasonally moving timber frame don't transfer stress into each other. This detail is agreed with the structural engineer before the formwork goes up.
Is access for concrete deliveries a problem on the High Street?+
It can be, particularly for properties directly on East Cross or the High Street, where loading restrictions and traffic apply. We survey access and, where needed, arrange temporary traffic management before booking the pour.
