Booked around your day
Most builds are booked within a week, longer in spring when garden project demand peaks across London. Catford (Southeastern) is the nearest station, so a SE6 visit rarely needs a whole morning set aside.

Same-week slots · Fully insured · Local Catford fitters · Fixed written pricesLooking for shed assembly in Catford SE6? We work in Catford most weeks — the fibreglass cat, the Broadway theatre and the Rushey Green shops — 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
Booked mostly by mixed-tenure households around Catford, shed assembly here covers supply-free fitting from £140. With 62% of Catford's 6,981 homes in flats, lift access and stair carries in SE6 shape the slot length we hold.
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. Catford (Southeastern) is the nearest station, so a SE6 visit rarely needs a whole morning set aside.
We expect with metal stud partitions between rooms, over dot-and-dab plasterboard over blockwork, and with 33% of homes here privately rented, it sets the booking date as often as the job does in SE6, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Catford gives us short screws that grip only the board and slowly lever it off the dabs, which is what a 62% flat share across the ONS neighbourhood covering Catford actually produces.
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. South Circular red route, shopping-centre service yards and permit bays behind.
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. |

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 Catford
Catford SE6 is mainly Victorian and mixed-tenure: 62% of homes here are flats and 38% are houses, across 6,981 households (ONS Census 2021).
The mixed-tenure mix here (42% owned, 33% privately rented) means a SE6 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Catford substrates run to with metal stud partitions between rooms, over dot-and-dab plasterboard over blockwork, and with 33% of homes here privately rented, it sets the booking date as often as the job does. Nothing is drilled until the wall has been sounded, because Catford gives us short screws that grip only the board and slowly lever it off the dabs, which is what a 62% flat share across the ONS neighbourhood covering Catford actually produces is the mistake that costs a SE6 customer twice.
Catford 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 fibreglass cat, the Broadway theatre and the Rushey Green shops — which is why a SE6 quote is not a Lewisham average.
On access, south Circular red route, shopping-centre service yards and permit bays behind — 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 Catford (Southeastern).

5m at the eaves within 2m of a boundary and all outbuildings together stay under half the garden for Catford (SE6) addresses, with 38% of Catford homes being houses.

Not once anchored. Terraced gardens funnel wind between the houses more than an open plot does — and 42% owner-occupation locally, with this being a short walk from Catford (Southeastern), so we fit ground anchors or wall straps as standard rather than leave it to the kit's own fixings, which is Catford gives us short screws that grip only the board and slowly lever it off the dabs on SE6 jobs, which is what a 62% flat share across the ONS neighbourhood covering Catford actually produces on unanchored builds we're called back to.

That paperwork is what most Lewisham letting agents and managing agents ask for before work starts in a leasehold flat on the streets near The Catford Cat, with 33% of SE6 homes being privately rented.
Laying a full concrete slab base — quoted separately as a groundworks job; Electrical supply to the shed for Catford (SE6) addresses, with a median age of 35 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.
