Westminster · W1 · Shed assembly
Same-week slots · Fully insured · Local Mayfair fitters · Fixed written pricesWe provide shed assembly in Mayfair W1 for houses and flats around Berkeley Square. From £140, quoted in writing before the visit, with one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together The base is checked for level before the first panel is stood up.
Overview
Shed assembly in Mayfair W1 is a fixed-price visit for renter-heavy homes in Westminster, most of them mixed-era. 3,555 households sit inside this W1 patch, 88% of them flats, so we quote on access near Berkeley Square rather than a London average.
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. Bond Street (Central, Jubilee, Elizabeth line) is the nearest station, so a W1 visit rarely needs a whole morning set aside.
We expect dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms, where 32% owner-occupation means the same home is booked again rather than a new tenant each year in W1, 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, as the Mayfair stock goes, and with 47% one-person households in Mayfair, one adult is usually the only pair of hands on site.
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. Extremely tight kerbside, mews arches under 2.1m and listed interiors needing floor and stair protection.
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. |

| 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 Mayfair
3,555 households sit inside the W1 neighbourhood covering Mayfair. The build is mixed-era, the tenure profile renter-heavy, and 88% of those homes are flats.
The renter-heavy mix here (32% owned, 57% privately rented) means a W1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms, where 32% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in Mayfair is chosen on site — the usual failure here is short screws that grip only the board and slowly lever it off the dabs, as the Mayfair stock goes, and with 47% one-person households in Mayfair, one adult is usually the only pair of hands on site.
Mayfair sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — grosvenor and Berkeley squares, private members' clubs and the flagship stores of Bond Street — which is why a W1 quote is not a Westminster average.
On access, extremely tight kerbside, mews arches under 2.1m and listed interiors needing floor and stair protection — 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 Bond Street (Central, Jubilee, Elizabeth line).

Small shed up to 6x4ft, base ready starts at £140 in Mayfair in this 88% flats neighbourhood — and a median age of 38 in this neighbourhood, with 47% one-person households here, 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 in Mayfair — and 32% owner-occupation locally, with a median age of 38 in this neighbourhood.
5m at the eaves within 2m of a boundary and all outbuildings together stay under half the garden on the Mayfair rounds, with this being Westminster City Council territory. Many gardens in Mayfair are small enough that a large shed pushes close to that limit — we check before booking rather than after the kit is built on Westminster bookings — and 32% owner-occupation locally, with 57% of W1 homes being privately rented.
Yes — a paving-slab base is £45/m², with 11% social-rented stock nearby, or a timber bearer base from £85 where a full slab isn't needed on W1 jobs. With 12% of Mayfair homes being houses with a garden, most jobs here are base-plus-build in one visit on the streets near Berkeley Square, with 12% of Mayfair homes being houses.
Not once anchored. Terraced gardens funnel wind between the houses more than an open plot does, so we fit ground anchors or wall straps as standard rather than leave it to the kit's own fixings on the Mayfair rounds, which is short screws that grip only the board and slowly lever it off the dabs, as the Mayfair stock goes, with 11% social-rented stock nearby — and 32% owner-occupation locally, and with 47% one-person households in Mayfair, one adult is usually the only pair of hands on site on unanchored builds we're called back to.
1m and listed interiors needing floor and stair protection for Mayfair (W1) addresses. Where a permit or a suspended bay is needed in Westminster City Council it is itemised on the quote before the visit, never added afterwards on the streets near Berkeley Square, with this being a short walk from Bond Street (Central, Jubilee, Elizabeth line).
Fitters carry £5m public liability cover. 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 around Bond Street (Central, Jubilee, Elizabeth line) — and 32% owner-occupation locally, with 11% social-rented stock nearby. That paperwork is what most Westminster letting agents and managing agents ask for before work starts in a leasehold flat in this 88% flats neighbourhood, with 57% of W1 homes being privately rented.
Laying a full concrete slab base — quoted separately as a groundworks job; Electrical supply to the shed for Mayfair (W1) addresses — and a median age of 38 in this neighbourhood, with 32% owner-occupation locally, 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. Anything outside that scope is quoted separately so the Mayfair W1 price you agree is the price you pay on the streets near Berkeley Square, with 11% social-rented stock nearby.
