Barnet · N11 · Shed assembly
Same-week slots · Fully insured · Local Friern Barnet and New Southgate fitters · Fixed written pricesBooking shed assembly near Princess Park Manor? Gated estate access codes at Princess Park Manor; driveways elsewhere, and that is planned into the slot rather than discovered on the day. Prices start at £140 and are fixed before we travel. The base is checked for level before the first panel is stood up.
Overview
This page prices shed assembly for Friern Barnet and New Southgate N11 specifically: mainly Victorian stock, 30% privately rented and 4,005 households in total. Work starts at £140, fixed in writing, with parking and London Borough of Barnet permit rules costed before an insured fitter travels.
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
Fitters carry £5m 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. Gated estate access codes at Princess Park Manor; driveways elsewhere.
Most builds are booked within a week, longer in spring when garden project demand peaks across London. New Southgate (Great Northern) is the nearest station, so a N11 visit rarely needs a whole morning set aside.
We expect with solid brick on the party and external walls, over lath and plaster over timber studs, measured on the walk in from New Southgate (Great Northern) rather than assumed from a map in N11, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is which crumbles the key and drops the panel — and a plasterboard plug spun into lime plaster, which is what a 47% flat share across the ONS neighbourhood covering Friern Barnet and New Southgate actually produces.
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. Permits, ULEZ and the Congestion Charge where they apply are itemised.
Scope
Sulltan is the best handyman in London. He is very reliable and professional. I highly recommend.
Really pleased with our house move. The guys came on time, loaded everything carefully like a huge jigsaw! Nothing got broken and even though they were working on an hourly rate they were really efficient, not to waste any time. Our only criticism is that we needed a few items disassembled to get on the… Read in full →

Working in Friern Barnet and New Southgate
4,005 households sit inside the N11 neighbourhood covering Friern Barnet and New Southgate. The build is mainly Victorian, the tenure profile owner-occupier-led, and 47% of those homes are flats.
The owner-occupier-led mix here (60% owned, 30% privately rented) means a N11 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Friern Barnet and New Southgate substrates run to with solid brick on the party and external walls, over lath and plaster over timber studs, measured on the walk in from New Southgate (Great Northern) rather than assumed from a map. Nothing is drilled until the wall has been sounded, because which crumbles the key and drops the panel — and a plasterboard plug spun into lime plaster, which is what a 47% flat share across the ONS neighbourhood covering Friern Barnet and New Southgate actually produces is the mistake that costs a N11 customer twice.
Quiet residential grid around the former Colney Hatch asylum, now Princess Park Manor. That character decides the practical detail of shed assembly here far more than the borough boundary does. Friern Barnet and New Southgate is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: gated estate access codes at Princess Park Manor; driveways elsewhere. New Southgate (Great Northern) is the nearest station, and one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together.

Small shed up to 6x4ft, base ready starts at £140 in Friern Barnet and New Southgate on the Friern Barnet and New Southgate rounds, with a median age of 40 in this neighbourhood — and 47% of homes here being flats, 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 on the streets near Princess Park Manor — and 30% of N11 homes being privately rented, with 47% of homes here being flats.
5m at the eaves within 2m of a boundary and all outbuildings together stay under half the garden on the Friern Barnet and New Southgate rounds, with this being a short walk from New Southgate (Great Northern).

Not once anchored. Terraced gardens funnel wind between the houses more than an open plot does on this side of Barnet, so we fit ground anchors or wall straps as standard rather than leave it to the kit's own fixings, which is which crumbles the key and drops the panel — and a plasterboard plug spun into lime plaster, with 25% one-person households here — and 53% of Friern Barnet and New Southgate homes being houses, which is what a 47% flat share across the ONS neighbourhood covering Friern Barnet and New Southgate actually produces on unanchored builds we're called back to.
