Scaffolding for a terraced house: elevations, end of terrace and the neighbours

Before you rely on this guide

This guide summarises published rules to help you plan and is not legal advice. It has not been reviewed by a qualified scaffold designer or engineer. ScaFix is a planning aid, not structural approval: the manufacturer's instructions, the scaffold design and a competent person's inspection decide what is built and used on site.

Which walls of a terraced house need scaffolding?

Only the elevations you are working on, and on a mid-terrace house that means the front and the rear. The side walls are party walls shared with the neighbours. An end-of-terrace house also has an exposed gable, which needs a scaffold up towards the ridge whenever the job covers the whole envelope, such as render, insulation or repointing.

A roof-only job, such as re-slating or new guttering, often needs a scaffold along the eaves on one or both elevations and nothing on the gable. Then the height that matters is the top lift under the eaves, and the scaffold also has to protect the roof edge. For that the top lift needs a protective screen higher than the guard-rail, such as brick guards or netting fitted to the manufacturer's instructions; the parts lists below count standard guard-rails only. Many Victorian terraces also have a rear outrigger (a narrower back addition), which turns the rear elevation into three short faces instead of one.

Worked example: a 4.85 m mid-terrace house

ScaFix has planned a two-storey terraced house: 4.85 m wide, 9 m deep, eaves at 5.2 m and the ridge at 8 m, with a flat rear wall and no outrigger. The front and rear become two independent runs of 4.88 m each (2 × 2.44 m), 0.76 m wide, boarded at 2.6 m and 4.6 m. Access is by ladders through hatch boards, the way the system is set up in ScaFix. The whole list for both runs:

Each run is 4.88 m long on a 4.85 m façade, so the scaffold reaches 2 cm past the party wall line at each end and stands slightly in front of both neighbours' walls. That is normal, because bay lengths rarely add up to a house width, but it means talking to both neighbours before the lorry arrives. The engine places 10 ties and 12 base jacks on the two runs; the contractor fixes the tie pattern to the design or the TG20:21 compliance sheet.

What does an end-of-terrace house add?

The gable is the biggest single item on an end-of-terrace house. The scaffold has to turn two corners, run the full 9 m depth of the house and climb towards the ridge at 8 m over the gable. In Kwikstage that is 184 more pieces than the mid-terrace house, and the scaffold face grows from 55 to 133 m².

This is how the engine lays out the three runs when front, gable and rear are connected:

The run lengths follow the bay lengths and the corner detail the engine chooses, so they are not the wall lengths. The gable run carries one boarded lift more than the front and rear, because the wall keeps rising towards the ridge. The parts that change from the mid-terrace to the end-of-terrace house:

How high does the scaffold go, and what does the law ask for?

The top boarded lift decides the working height, not the ridge. In this example it sits at 4.6 m along the elevations, 0.6 m under the eaves, so the gutter line sits just above the boards, and at 6.6 m in the bays under the ridge. Every boarded lift a person could fall from needs full edge protection.

Under Schedule 2 of the Work at Height Regulations 2005 the top guard-rail is at least 950 mm above the edge and no unprotected gap exceeds 470 mm, with toe-boards where materials could fall. A scaffold used for work at height is inspected before first use and then within every 7 days (regulation 12). How high a scaffold may go before it needs a bespoke design is in how high can scaffolding be.

How do the parts reach the back of a terrace?

Usually through the house, along a shared back alley, or over a neighbour's garden, because a mid-terrace house rarely has side access to its rear. Roughly half of the 164 pieces belong to the rear run, and every standard, ledger and board is carried by hand. Agree the route with the occupants before the lorry comes.

Protect floors and door frames on the way through. Where several houses in the row share the job, the rear scaffold can start at the end of the terrace and extend house by house. That saves carrying through living rooms, but only works when every neighbour has agreed to the scaffold standing in front of their wall and over their garden for the whole job.

What are your rights over a neighbour's land?

In England and Wales there is no automatic right to put scaffolding on next door's land. If a neighbour refuses, the Access to Neighbouring Land Act 1992 lets you apply to the court for an access order, but only for works reasonably necessary to preserve your property, including the maintenance, repair or renewal of a building.

A written agreement is therefore the normal route: how long the scaffold stays, where it stands, who makes good any damage to paths or planting, and whether sheeting is fitted. A court order is slow and costly, so the conversation should start well before the job is booked, ideally with a simple plan of where the standards will go.

Is it worth scaffolding the whole terrace at once?

Yes, when the houses need the same work. ScaFix has planned 4 terraced houses in Kwikstage as one long run along the street and one along the gardens: 458 pieces, or 115 per house against 164 for one house alone.

The ends of the runs, with their end guard-rails, toe-boards and extra standards, come once instead of once per house, and the access is shared. The scaffold is also erected and struck once, not 4 times, under one design. The trade-off is that every household lives with the scaffold for the same period, and one slow house keeps it up for everybody. That is why housing associations usually scaffold a whole block for a re-roofing or insulation programme.

Which scaffold system suits a terraced house?

Any of the common façade systems does the job, and the difference shows in the parts rather than the height. Most UK domestic scaffolds are still tube and fitting to TG20:21; ScaFix plans system scaffolds, and has run the same house in two of them. The piece count says something about carrying and erection time, not about price or quality:

HAKI Universal is set up with a stair tower for access in ScaFix, which explains part of its higher count. For tube and fitting quantities on a straight wall, see tube and fitting scaffold quantities.

Do you need a licence for scaffolding in front of a terraced house?

Yes, whenever the scaffold stands on or over the pavement or road, which is common where a terrace fronts straight onto the street. Section 169 of the Highways Act 1980 requires a licence from the highway authority, and the council attaches conditions. A scaffold wholly inside your own front garden needs no highway licence.

The council's licence and the neighbours' permission are separate things: a terrace job often needs both. Councils, lead times and how to apply are covered in do I need a scaffolding permit.

Planning a terraced house in ScaFix

Enter the front and the rear as two walls with the house width and the eaves height, not connected to each other. For an end-of-terrace house, connect the gable between them and set it as a gable wall with the ridge height. The engine lays out the bays, lifts, ties and base jacks, gives the parts list for the house and shows the scaffold in 3D before anything is ordered. For a detached house with four elevations, scaffolding for a house is the better starting point, and scaffold quantities by wall size lists one wall at every size.

The worked example is a planning aid, not structural approval. The manufacturer's instructions, the design or TG20:21 compliance sheet and inspection by a competent person decide.
