London shed assembly · South London
Shed assembly across Lewisham, from SE12, SE13 and SE14 outwards. Deptford's market and Victorian New Cross, hill villages at Blackheath and Forest Hill, and Catford's high street, and that is what shapes every quote we write here.
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.
Working in Lewisham
The stock in Lewisham is victorian and edwardian terraces and conversions, 1960s catford estates and new lewisham town-centre towers, and the mix changes street by street — Bellingham and Downham (SE6), Brockley (SE4) and Catford (SE6) each behave differently on the day.
London Borough of Lewisham sets the constraint: steep hills at honor oak and forest hill, narrow terraced streets and expanding cpzs across se4 and se14. Locally that means wide estate roads with kerbside parking and level access — easy for a luton and steep hills, long front paths and conversion flats up two or three flights. Lewisham sits outside the Congestion Charge zone, so only ULEZ applies to the van and the quote is that much simpler.
Leases across Lewisham restrict drilling into party and structural walls. We check what the wall actually is before we start, and where consent is needed we say so rather than fixing anyway.
Why it looks like this: kentish villages absorbed by railways from the 1840s; deptford's naval dockyard and deptford creek shaped its industrial edge.
Scope
Method
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.
Coverage
Also in this borough
Garden sets, loungers, BBQs, parasols and shed bases built outside and weather-fixed.
Fitted and flat-pack wardrobes scribed to the wall and anchored so doors stay square.
TVs, mirrors, shelves and curtain poles fixed into the wall you actually have, in one visit.
Wardrobes, beds, desks and storage built, levelled and anchored to the wall.
Sheds emptied, dismantled and the base left clear and swept.
Small shed up to 6x4ft, base ready starts at £140 in Lewisham, and the ladder runs up to £60 for the largest job on the table above. 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. The borough is outside the Congestion Charge zone, so there is no charge to pass on — only ULEZ, which our vans are compliant with.
We cover the whole borough: SE12, SE13, SE14, SE23, SE26, SE4, SE6 and SE8. On the ground that includes Bellingham and Downham, Brockley, Catford, Deptford, Forest Hill and Grove Park.
Most builds are booked within a week, longer in spring when garden project demand peaks across London. South London is covered by crews already working in the borough, so travel time is not billed on top.
Steep hills at Honor Oak and Forest Hill, narrow terraced streets and expanding CPZs across SE4 and SE14. Where a permit or a bay suspension is needed we arrange it with London Borough of Lewisham and show the cost in the quote before you agree it. Nothing is added afterwards.
Yes. Victorian and Edwardian terraces and conversions, 1960s Catford estates and new Lewisham town-centre towers is exactly the stock we work in daily. Where there is no lift, the crew size is set by the floor level at quote stage, so a third-floor walk-up is priced as a third-floor walk-up rather than re-quoted on the doorstep.
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. Certificates go out with the booking confirmation, which is what London Borough of Lewisham tenancies and most local managing agents ask for.
One fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Vehicles are ULEZ-compliant, which matters in every Lewisham postcode, and the crew carries everything needed to complete the job in one visit.
Laying a full concrete slab base — quoted separately as a groundworks job, Electrical supply to the shed, which needs a registered electrician for the armoured cable and consumer unit work and Party wall or boundary consent where a shed sits within 2m of a neighbour's fence and exceeds the height limit. If something on that list turns up in Lewisham, we tell you at survey and point you at the right trade rather than taking the booking anyway.

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 →
