One structure for the whole build
Planned properly at survey stage, the same scaffold can serve brickwork, roofing and finishing without a second build part-way through.
Extension build access
From a single-storey side return to a full double-storey extension, we build access that keeps bricklayers, roofers and window fitters working safely without getting in the way of the build below.

The service
An extension project usually runs for months, with several trades needing access at different heights and different stages; foundations and brickwork first, then roofing, then windows, render and finishing. Thompsons Towers builds scaffolding designed to serve the whole sequence rather than something that has to be adjusted every fortnight.
We're a family-run scaffolding company based in Hadlow near Tonbridge. Mason runs the build side on site and Katie manages the office, quotes and communication with you or your main contractor, so there's always a clear point of contact through a long-running job.
Because extensions often go up against an existing house, we look carefully at how the new scaffold ties into what's already there; shared walls, existing gutters, drainpipes and neighbouring boundaries all affect how the structure is designed at survey stage.
Every job starts with a free site survey and a written quote back within a day, so you know the access cost before committing to the wider build programme. A standard six-week hire period is included, with easy extension if the build overruns.
We cover extension projects across Tonbridge, Tunbridge Wells, Hadlow, Kings Hill, Paddock Wood, Maidstone, Sevenoaks, Ashford, Canterbury, Dartford, Gravesend and London, working alongside builders, architects and homeowners managing the project directly.
Builders, main contractors and homeowners project-managing an extension, from a single-storey side return to a full double-storey rebuild.
From first-fix brickwork through roofing, guttering, window installation and external render or cladding.
A multi-trade, multi-stage build needs a platform that's stable, correctly loaded and adaptable as the work progresses; not a fixed tower moved trade to trade.
What it costs to wait
Extensions are rarely a single, uniform elevation; they step in and out from the existing house, change height between storeys, and often sit close to boundaries. Get the scaffold plan wrong and it slows every trade that follows.
A single-storey extension against a two-storey house means the scaffold has to step and adapt across the elevation, which needs planning rather than a standard straight run.
Side-return and rear extensions are often built on narrow gaps between houses, so the scaffold footprint has to be worked out carefully to avoid blocking access or overhanging a boundary without agreement.
Brickies, roofers, electricians and window fitters may all need the platform in the same week, so it has to be rated and configured to take that traffic safely.
Our process
We visit the plot, look at the extension drawings if available, and assess how the scaffold should step and tie in against the existing house.
A clear, itemised quote comes back within one day, covering the standard six-week hire and any design work needed for a non-standard layout.
Our CISRS-carded team erects the scaffold in the sequence your build needs, from foundation-level access through to roof height.
RAMS, scaff tags and inspection records are handed over so every trade using the platform has what they need before starting.
We adjust the platform as the build progresses, inspect weekly, and take it down once the extension is signed off.
What you get
Planned properly at survey stage, the same scaffold can serve brickwork, roofing and finishing without a second build part-way through.
A correctly loaded, edge-protected platform means bricklayers, roofers and window fitters aren't sharing an undersized structure.
Tied and braced to suit the elevation, the scaffold holds up through the whole build period, not just the first few weeks.
Our price promise means we'll beat any genuine written quote, so the access budget is settled before the build even starts.
Katie coordinates timing directly with contractors, so the scaffold is up and ready when the build programme needs it.
Known locally as the posh scaffolders, we build and dismantle cleanly; important on a tight plot next to someone else's garden or drive.
In detail
Extension access has to flex with the build, which means more planning up front than a straightforward single-elevation job.
Most extension scaffolds use tube and fitting or a modern system scaffold, chosen for how quickly it can be reconfigured as the extension progresses. Boards form the working deck at each lift, with guard rails and toe boards fitted at every stage rather than just the top lift.
Where render, cladding or brick slips are being applied at the finishing stage, we build in extra standoff space from the wall so those trades have room to work without the scaffold sitting flush against wet or uncured material.
Because extensions step in height against the existing house, we build in lifts that match the new roofline, often independent from the main house scaffold but tied back at key points for stability. Loading bays are positioned so bricks, blocks and roofing materials can be lifted straight to the working level.
On tight plots we plan the footprint down to the last few centimetres at survey stage, checking boundary lines and any access agreements needed with neighbours before the build goes up.
A single-storey side-return extension typically needs a simpler, lower platform than a double-storey rear extension, which may need full-height access with more ties and bracing. Loft conversions combined with an extension add another layer of complexity, often needing a stepped platform across two rooflines.
We also vary the build for extensions with a flat roof versus a pitched roof, since flat roofs often need a safer perimeter edge protection setup for ongoing access during the roofing and waterproofing stage.
This covers side-return extensions, rear extensions, wraparounds, double-storey additions and loft conversions built alongside an extension. It also applies where an extension links to garage conversions or outbuildings needing their own access.
It's common for extension scaffolding to run alongside renovation work on the rest of the house, in which case we'll plan a single combined structure rather than two separate builds where the footprint allows it.
The large majority of extension scaffolding we do is residential; family homes across Tonbridge, Tunbridge Wells, Maidstone and the surrounding villages; where the build needs to be practical for a family still living in the house during the works.
Commercial extensions, such as an addition to an office, school or care building, usually need a formally designed scaffold with drawings and calculations, available at extra charge, along with closer coordination around public access and working hours.
Common questions
Still unsure? Ring 07355 037000 and speak to Katie or Mason directly.
It depends on the size and height of the extension and how it ties into the existing house, so we quote after a free survey. We'll beat any genuine written quote you've already had.
A typical extension scaffold takes one to a few days depending on size and access, and we'll confirm timing in the written quote so it fits your build programme.
