Overview
Shed assembly in Chiswick W4, explained
Booked mostly by mixed-tenure households around Turnham Green, shed assembly here covers supply-free fitting from £140. With 57% of Chiswick's 15,273 homes in flats, lift access and stair carries in W4 shape the slot length we hold.
How it works
How shed assembly works in Chiswick
Five steps, the same on every W4 job, so you know what happens before you commit. New-build and conversion flats lined with dot-and-dab plasterboard, as the Chiswick stock goes, and with 34% of homes here privately rented, it sets the booking date as often as the job does 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 Chiswick customers book us
Four things decide whether a W4 job goes well, and none of them are visible from a price list.
Booked around your day
Most builds are booked within a week, longer in spring when garden project demand peaks across London. Turnham Green (District, Piccadilly) is the nearest station, so a W4 visit rarely needs a whole morning set aside.
Chiswick walls, not generic walls
We expect dot-and-dab plasterboard over blockwork in Chiswick, with metal stud partitions between rooms — the reality on the streets around Chiswick House and Gardens in W4, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is short screws that grip only the board and slowly lever it off the dabs on these streets — which is why London Borough of Hounslow kerb rules get settled before the van is loaded.
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.
Fixed prices
Shed assembly prices in Chiswick
Fixed prices for W4 and the rest of Hounslow. 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. |

Scope
What's included in Chiswick
The same scope across W4, whether the job is a single item or a full room.
Included in the price
- On W4 jobs: kit checked against the manual and the panel list before the first screw goes in, with 57% of homes here being flats, planned around the stair or the lift
- In Chiswick: frame squared and braced before roof panels go on, so doors don't bind later, the way it is done on Chiswick jobs
- Felt or shingle roofing lapped and nailed to the manufacturer's pattern — including shed assembly
- Standard on Hounslow bookings: anchoring or ground pins fitted as standard in exposed gardens, arranged with London Borough of Hounslow where the kerb needs it
Not included
- Laying a full concrete slab base — quoted separately as a groundworks job, quoted separately if you need it arranged in W4
- Electrical supply to the shed, which needs a registered electrician for the armoured cable and consumer unit work, which we refer on to the right trade in Chiswick
- Party wall or boundary consent where a shed sits within 2m of a neighbour's fence and exceeds the height limit, handled by London Borough of Hounslow or a specialist contractor instead

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 →

Common questions
Shed assembly in Chiswick W4 — your questions.
How much does shed assembly cost in Chiswick W4?
Small shed up to 6x4ft, base ready starts at £140 in Chiswick on Hounslow bookings — and 51% owner-occupation locally, with a median age of 40 in this neighbourhood, 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 W4 jobs — and this being a short walk from Turnham Green (District, Piccadilly), with 34% one-person households here.
Do I need permission for a shed in my Chiswick W4 garden?
5m at the eaves within 2m of a boundary and all outbuildings together stay under half the garden on the Chiswick rounds, with Chiswick House and Gardens a few streets away. Many gardens in Chiswick are small enough that a large shed pushes close to that limit — we check before booking rather than after the kit is built on W4 jobs — and this being London Borough of Hounslow territory, with 34% of W4 homes being privately rented.
Can you build a shed base as well as the shed in W4?
Yes — a paving-slab base is £45/m², with 34% one-person households here, or a timber bearer base from £85 where a full slab isn't needed across W4. With 43% of Chiswick homes being houses with a garden, most jobs here are base-plus-build in one visit on the streets near Chiswick House and Gardens, with 15,273 households on this patch.
Will the shed blow over in an exposed Chiswick garden?
Not once anchored. Terraced gardens funnel wind between the houses more than an open plot does on W4 jobs, so we fit ground anchors or wall straps as standard rather than leave it to the kit's own fixings — and 57% of homes here being flats, with Hounslow parking rules in play, which is short screws that grip only the board and slowly lever it off the dabs on these streets — which is why London Borough of Hounslow kerb rules get settled before the van is loaded on unanchored builds we're called back to.
Who books shed assembly in Chiswick W4 — tenants, landlords or owners?
All three. With 34% of Chiswick privately rented and 51% owner-occupied, roughly half the W4 diary is agent- or landlord-instructed and invoiced separately from the person at the door in this 57% flats neighbourhood — and this being London Borough of Hounslow territory, with 34% of W4 homes being privately rented.
How quickly can you reach Chiswick from your Hounslow round?
Chiswick House and Gardens is the marker we route to on this side of Hounslow, with 57% of homes here being flats, and conservation-area rules, A4 red route and very tight CPZ around Turnham Green. A W4 slot added to an existing Hounslow round usually lands the same week rather than the next in this 57% flats neighbourhood, with this being London Borough of Hounslow territory.
Is same-day or evening shed assembly available in Hounslow?
Most builds are booked within a week, longer in spring when garden project demand peaks across London on this side of Hounslow, with 15,273 households on this patch. Chiswick sits close to Turnham Green (District, Piccadilly) in Chiswick, with a median age of 40 in this neighbourhood, so we can usually add a W4 job to an existing Hounslow round at short notice.
