Barnet · N20 · Shed assembly
Same-week slots · Fully insured · Local Totteridge fitters · Fixed written pricesLooking for shed assembly in Totteridge N20? We work in Totteridge most weeks — green-belt lane of large houses, paddocks and a village pond — and price shed assembly against that reality rather than a London average. Fixed written quote from £140, insured fitters, the frame squared before roofing and anchors fitted where needed.
Overview
Shed assembly in Totteridge N20 is a fixed-price visit for owner-occupier-led homes in Barnet, most of them mixed-era. 3,519 households sit inside this N20 patch, 12% of them flats, so we quote on access near Totteridge Green and the village pond rather than a London average.
How it works
Step 1
Base checked for level and size, and the shed's height and position checked against the garden's remaining permitted development allowance.
Step 2
Panels, roof struts and fixings checked against the parts list — a shed with a bent panel or a short bag of screws is found before the frame goes up, not halfway through.
Step 3
Floor and wall panels built up and squared before the roof goes on, since an out-of-square frame is what makes doors stick.
Step 4
Roof panels fitted, felt or shingle lapped correctly and any window or vent sealed.
Step 5
Ground anchors or wall straps fitted in exposed gardens, doors hung and eased, packaging taken away.
Why choose us
Most builds are booked within a week, longer in spring when garden project demand peaks across London. Totteridge & Whetstone (Northern), at the foot of Totteridge Lane is the nearest station, so a N20 visit rarely needs a whole morning set aside.
We expect timber stud partitions inside; locally that also means cavity brickwork outside, measured on the walk in from Totteridge & Whetstone (Northern), at the foot of Totteridge Lane rather than assumed from a map in N20, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is a four-hole bracket with two screws in a stud and two in fresh air, as the Totteridge stock goes, a median age of 44 in this neighbourhood shapes what gets ordered here.
Fitters carry £1m public liability cover. Most garden sheds fall under permitted development if they sit under 2.5m at the eaves within 2m of a boundary and the total of all outbuildings stays under 50% of the garden — we flag it if a build looks close to either limit rather than assume it is fine.
One fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Long gravel drives, narrow lanes without passing places and gated entrances.
Fixed prices
| Job | From | Typical time | What sets the price |
|---|---|---|---|
| Small shed up to 6x4ft, base ready | £140 | 2–3 hrs | A one-piece or simple panel shed on an existing slab, framed, roofed and felted in a morning. |
| Medium shed 8x6ft, base ready | £220 | 3–5 hrs | More panels and a ridged roof mean more bracing before the structure is rigid enough to felt. |
| Large shed or workshop 10x8ft+, base ready | £320 | 5–7 hrs | Heavier framing, often double doors and a window, and usually a two-person lift for the roof panels. |
| Paving-slab base, per m² | £45 | By area | Compacted hardcore and a sand bed under the slabs, laid to a slight fall so water runs away from the shed floor. |
| Timber bearer base on an existing hard surface | £85 | 2–3 hrs | Pressure-treated bearers levelled and packed to keep the shed floor off standing water without a full slab. |
| Anchor kit for an exposed or elevated garden | £60 | 45–60 min | Ground anchors or wall straps fitted so the shed does not lift in a gust funnelled between two terraces. |

Prices are labour to build the kit you supply, on a base that is level and ready. Roofing felt, fixings and standard anchor kits are included; a bespoke concrete base is quoted separately by the m². We flag before booking where a build looks close to the 2.5m eaves height or 50%-of-garden permitted development limits so you can check before ordering.

Scope

Working in Totteridge
In Totteridge (N20) the split is 12% flats to 85% houses over 3,519 households, and the stock is mixed-era.
With 14% private renting against 75% owner-occupied, most N20 bookings land on a move-in day rather than a weekend.
Walls are timber stud partitions inside; locally that also means cavity brickwork outside, measured on the walk in from Totteridge & Whetstone (Northern), at the foot of Totteridge Lane rather than assumed from a map, so the fixing that matters in Totteridge is chosen on site — the usual failure here is a four-hole bracket with two screws in a stud and two in fresh air, as the Totteridge stock goes, a median age of 44 in this neighbourhood shapes what gets ordered here.
Totteridge is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — green-belt lane of large houses, paddocks and a village pond — which is why a N20 quote is not a Barnet average.
On access, long gravel drives, narrow lanes without passing places and gated entrances — one reason one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Fitters travelling in use Totteridge & Whetstone (Northern), at the foot of Totteridge Lane.

Small shed up to 6x4ft, base ready starts at £140 in Totteridge on Barnet bookings, with Barnet parking rules in play — and 22% one-person households here, and every job is quoted as a fixed written price before a fitter is booked. Shed size and whether the base already exists. A slab or bearer base adds a separate charge but saves the shed floor from sitting on wet grass or bare soil through its first winter for Totteridge (N20) addresses — and 85% of Totteridge homes being houses, with 3,519 households on this patch.
5m at the eaves within 2m of a boundary and all outbuildings together stay under half the garden on N20 jobs, with 85% of Totteridge homes being houses. Many gardens in Totteridge are small enough that a large shed pushes close to that limit — we check before booking rather than after the kit is built on this side of Barnet — and a median age of 44 in this neighbourhood, with 11% social-rented stock nearby.
Yes — a paving-slab base is £45/m², with 3,519 households on this patch, or a timber bearer base from £85 where a full slab isn't needed on the Totteridge rounds. With 85% of Totteridge homes being houses with a garden, most jobs here are base-plus-build in one visit around Totteridge & Whetstone (Northern), at the foot of Totteridge Lane, with a median age of 44 in this neighbourhood.
Not once anchored. Terraced gardens funnel wind between the houses more than an open plot does, with 11% social-rented stock nearby, so we fit ground anchors or wall straps as standard rather than leave it to the kit's own fixings around Totteridge & Whetstone (Northern), at the foot of Totteridge Lane — and 75% owner-occupation locally, which is a four-hole bracket with two screws in a stud and two in fresh air, as the Totteridge stock goes, a median age of 44 in this neighbourhood shapes what gets ordered here on unanchored builds we're called back to.
Long gravel drives, narrow lanes without passing places and gated entrances on N20 jobs. Where a permit or a suspended bay is needed in London Borough of Barnet it is itemised on the quote before the visit, never added afterwards on the streets near Totteridge Green and the village pond — and 11% social-rented stock nearby, with a median age of 44 in this neighbourhood.
Fitters carry £1m public liability cover. 5m at the eaves within 2m of a boundary and the total of all outbuildings stays under 50% of the garden — we flag it if a build looks close to either limit rather than assume it is fine on the streets near Totteridge Green and the village pond — and 75% owner-occupation locally, with 22% one-person households here. That paperwork is what most Barnet letting agents and managing agents ask for before work starts in a leasehold flat on N20 jobs, with this being London Borough of Barnet territory.
Laying a full concrete slab base — quoted separately as a groundworks job; Electrical supply to the shed across N20 — and 3,519 households on this patch, with a median age of 44 in this neighbourhood, which needs a registered electrician for the armoured cable and consumer unit work; Party wall or boundary consent where a shed sits within 2m of a neighbour's fence and exceeds the height limit. Anything outside that scope is quoted separately so the Totteridge N20 price you agree is the price you pay on this side of Barnet, with 3,519 households on this patch.
