Overview
Shed assembly in Colindale NW9, explained
This page prices shed assembly for Colindale NW9 specifically: inter-war stock, 35% privately rented and 7,659 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
How shed assembly works in Colindale
Five steps, the same on every NW9 job, so you know what happens before you commit. Council and housing-association blocks built from precast concrete and dense block on these streets — measured on the walk in from Colindale (Northern) rather than assumed from a map is what we plan for here.
Step 1
Check the base and the plot
Base checked for level and size, and the shed's height and position checked against the garden's remaining permitted development allowance.
Step 2
Unpack and count
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
Frame and square
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 and weatherproof
Roof panels fitted, felt or shingle lapped correctly and any window or vent sealed.
Step 5
Anchor and finish
Ground anchors or wall straps fitted in exposed gardens, doors hung and eased, packaging taken away.
Why choose us
Why Colindale customers book us
What follows is specific to Colindale: its walls, its access and the paperwork Barnet agents ask for.
Colindale walls, not generic walls
We expect precast concrete panels and dense blockwork; locally that also means often with surface conduit, and with 30% one-person households in Colindale, one adult is usually the only pair of hands on site in NW9, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Colindale gives us drilling blind into a panel with reinforcement or a buried cable behind it, the reality on the streets around The former Hendon Aerodrome and Colindale Gardens.
Insured and documented
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.
Crew sized to the job
One fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Every new block requires booked goods lifts and loading bays; estate roads are gated.
Fixed prices
Shed assembly prices in Colindale
Fixed prices for NW9 and the rest of Barnet. 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.
| 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
What's included in Colindale
The same scope across NW9, whether the job is a single item or a full room.
Included in the price
- Standard on Barnet bookings: kit checked against the manual and the panel list before the first screw goes in, with 7,659 households in this neighbourhood, it is the question we are asked most
- Frame squared and braced before roof panels go on, so doors don't bind later, checked on every NW9 visit
- In Colindale: felt or shingle roofing lapped and nailed to the manufacturer's pattern, sized for the every new block requires booked goods lifts and loading bays; estate roads are gated
- On NW9 jobs: anchoring or ground pins fitted as standard in exposed gardens, shed assembly prices included
Not included
- Laying a full concrete slab base — quoted separately as a groundworks job, which we refer on to the right trade in Colindale
- Electrical supply to the shed, which needs a registered electrician for the armoured cable and consumer unit work, quoted separately if you need it arranged in NW9
- Party wall or boundary consent where a shed sits within 2m of a neighbour's fence and exceeds the height limit, and we will say so before the NW9 visit rather than on the day

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.

Colindale NW9 at a glance
Published figures for the neighbourhood that covers Colindale — the numbers that actually change a shed assembly quote.
7,659 households sit inside the NW9 neighbourhood covering Colindale. The build is inter-war, the tenure profile renter-heavy, and 80% of those homes are flats.
The renter-heavy mix here (32% owned, 35% privately rented) means a NW9 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Colindale substrates run to precast concrete panels and dense blockwork; locally that also means often with surface conduit, and with 30% one-person households in Colindale, one adult is usually the only pair of hands on site. Nothing is drilled until the wall has been sounded, because Colindale gives us drilling blind into a panel with reinforcement or a buried cable behind it, the reality on the streets around The former Hendon Aerodrome and Colindale Gardens is the mistake that costs a NW9 customer twice.
Colindale 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 — the fastest-growing new-build district in north London, around the old aerodrome — which is why a NW9 quote is not a Barnet average.
Getting to the door matters as much as the job: every new block requires booked goods lifts and loading bays; estate roads are gated. Colindale (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.

Will the shed blow over in an exposed Colindale garden?
