Planning a house extension is an exciting step. But before the walls go up or the roof goes on, you’ll need something just as important — safe, reliable scaffolding.
Whether you’re building a rear extension in Fulwell, a double-storey side extension in Ashbrooke, or a kitchen wraparound in Barnes, scaffolding plays a key role in keeping your project safe and on schedule.
At Scaffolding Sunderland, we’ve supported dozens of local extensions across the city. In this guide, we’ll explain what type of scaffolding you need for an extension, how much it costs, and what to look out for when hiring a provider.
Why scaffolding is essential for house extensions
Most house extensions involve work at height. Roof structures, bricklaying, rendering, and window installation all require stable access platforms.
Scaffolding provides a safe and secure working area for builders, roofers, and tradespeople. It also helps protect your property from falling materials and keeps the job site tidy.
Some homeowners ask whether scaffolding is really necessary for small extensions. The short answer is yes — even single-storey builds can benefit from proper scaffold access.
It speeds up the job, reduces risk, and ensures the work is done to a higher standard.
Types of scaffolding used for extensions
The type of scaffolding you need depends on the size and layout of your extension.
Rear extension
Rear extensions often need scaffolding at the back of the property, which may involve tight garden access. A narrow scaffold or system tower may be used if space is limited.
If the existing roofline is being altered or joined with the new structure, you may also need scaffold access across the roof to connect both areas safely.
Side extension
Side extensions typically require scaffolding along one full elevation. If the roof is being extended or raised, double-height scaffolds with edge protection will be used.
In some cases, the scaffold may need to bridge over a conservatory, garage, or side gate.
Wraparound extension
For L-shaped or wraparound extensions, the scaffold will need to follow the full perimeter. This often involves corner platforms, working lifts, and multiple ladder access points.
At Scaffolding Sunderland, we visit every property in person to design the safest and most efficient scaffold layout for your build.
Scaffold design considerations
Every extension is different, but here are a few key things we assess when planning your scaffold:
- Access routes through the garden or side of the house
- Ground conditions (paved, grass, sloped, or soft ground)
- Obstructions like sheds, trees, or fences
- Height and footprint of the extension
- Tie-in points to existing walls or buildings
- Whether the old roof needs removing or adjusting
Once we understand these details, we build a scaffold plan that fits your site perfectly.
How much does extension scaffolding cost in Sunderland?
Scaffolding prices for house extensions vary based on the size and complexity of the project.
Here are some rough figures based on typical jobs around Sunderland:
- Single-storey rear extension: £450 to £700
- Double-storey side extension: £700 to £1,200
- Full wraparound extension: £1,200 to £2,000
- Weekly extension beyond the initial hire: £50 to £100 per week
Most scaffolding jobs include four to six weeks of hire as standard. If your build runs longer, you can extend the hire weekly.
We always provide a fixed quote with clear breakdowns before we begin. That way, there are no surprises later.
How long does scaffold installation take?
Scaffold for house extensions can usually be erected in one day.
For smaller extensions, installation may take just a few hours. Larger builds with wraparound access or bridging beams may take a full day.
At Scaffolding Sunderland, we always aim to install the scaffold one to two days before the building work starts. That gives your contractor plenty of time to begin without delays.
Do I need a permit for extension scaffolding?
If your scaffold sits entirely on your private land — like your garden, driveway, or side alley — you usually don’t need a permit.
However, if the scaffold extends over a footpath, pavement, or shared driveway, a permit may be required from Sunderland City Council.
We’ll let you know if this applies during our site visit and can handle the application process on your behalf.
Safety features included
Every scaffold we install comes with essential safety features, including:
- Guard rails for fall protection
- Toe boards to prevent dropped tools
- Ladder access tied securely to the scaffold
- Base plates and sole boards for stability
- Debris netting (where required)
We follow TG20:21 guidelines and inspect all scaffolds before use and at regular intervals during the project.
Tips for homeowners during the build
Here are a few tips to help things go smoothly while your extension is being built:
- Keep access areas clear for scaffolders and builders
- Inform neighbours about the work to avoid complaints
- Avoid walking under the scaffold once construction begins
- Report any signs of damage or movement
- Don’t let children or pets near the scaffold
