Structural alterations in Tenterden most commonly come to us as either an opening-up job on a Grade II weatherboarded townhouse near the High Street, or a wall removal or steel installation on the 1970s East Cross estate housing further out towards Ashford Road.
The construction underneath the weatherboarding on the older townhouses is usually a timber frame, sometimes with later brick infill or refacing, and identifying exactly what is carrying load before quoting is the single most important step on these jobs.
What's under the weatherboarding
Weatherboarded townhouses along the High Street typically have a timber frame as the primary structure, with the external boarding simply cladding it rather than carrying any load. Internally, though, later partitions and even some apparently structural-looking walls may have been added or altered over the centuries, so an opening-up survey — sometimes involving removing a small section of plaster or board to expose the frame — is standard practice before committing to a specific structural design.
Where the frame itself needs strengthening or a new opening formed through a genuine bracing member, we bring in a structural engineer familiar with historic timber construction, since a standard steel beam calculation intended for brick and block doesn't translate directly to a jointed timber frame.
Listed building consent and the High Weald AONB
Many High Street properties are Grade II listed, meaning internal structural alterations need listed building consent from Ashford Borough Council in addition to any building control sign-off for the structural work itself. The wider setting within the High Weald Area of Outstanding Natural Beauty doesn't generally affect internal structural work, but it does reinforce how carefully the council scrutinises any change that could affect the external appearance or historic character of these buildings.
For unlisted properties within the Tenterden Conservation Area boundary, purely internal structural work is less likely to need planning permission, though building control approval for the structural design and construction is required regardless of listed status or conservation area.
Standard steel and masonry work on the East Cross estates
The 1970s housing around East Cross and further towards Ashford Road is generally straightforward cavity or timber-frame construction, and removing a load-bearing wall here follows the standard process: engineer's calculation for the new beam, temporary propping, wall removal, beam installation and building control inspection at each stage.
These properties rarely carry listed status or fall inside conservation area boundaries, so permitted development typically covers the change itself, with building control remaining the main statutory requirement.
Sequencing around a live household
On the older High Street properties, structural work often needs to proceed in a more staged sequence than on a modern house, because temporary propping has to work around uneven original floor levels and irregular room shapes rather than a uniform modern floor plate. We plan propping points around what the existing floor structure can actually take rather than a standard grid, which sometimes means a slightly longer programme for the same size of opening.
On estate properties this staging is far more predictable, and jobs generally run to a standard timeline for the size of opening involved.
Building control and completion certificates
Whatever the building type, a structural alteration needs building control sign-off confirming the new structure meets current standards, and this certificate matters at resale — buyers' solicitors routinely ask for it. On listed buildings we keep listed building consent and building control approval as two clearly separate pieces of paperwork, since one does not substitute for the other.
Common questions
Is the wall I want to remove actually load-bearing on a weatherboarded townhouse?+
It depends on the specific building — in a genuine timber-framed townhouse, some internal walls are non-structural later additions while others tie into the main frame. An opening-up survey, sometimes exposing a small section of the frame, establishes this before any structural design is finalised.
Do I need both planning permission and listed building consent for a wall removal?+
If your property is listed, listed building consent is typically required for internal structural alterations regardless of whether planning permission is also needed. Building control approval for the structural design is a separate, additional requirement in every case.
Are structural jobs on the East Cross estates quicker to complete?+
Generally yes — the construction is standard cavity or timber-frame, propping can follow a predictable grid, and there's usually no listed building consent to factor into the programme, so these jobs tend to run to a more standard timeline.
