Rear and side-return extensions, loft conversions, garage conversions and full renovations across Woolwich — fixed staged price, drawings and building control handled, site cleared at the end.
Since the Elizabeth line arrived, extending in Woolwich makes more sense than moving out of it. A side return on a Plumstead terrace or a dormer loft in Eltham adds the room you actually need — and usually more than it costs.
Single and double-storey extensions built from footings to finish — steels calculated, drainage dealt with properly, and the room plastered and made good.
Unused roof space turned into bedrooms and a shower room — stairs designed in, head height checked before you commit, building regs signed off.
Garages converted into a room that is actually warm — floor insulated, walls lined, damp dealt with, and the front elevation made to look intended.
Whole-house refurbishments run as one job on one programme, so the trades follow each other in the right order instead of tripping over one another.
Walls taken out, steels sized by an engineer and installed properly, openings formed and the ceiling and floor made good so you cannot tell where it was.
Footings dug and poured, drains diverted or built over with the right agreements in place, and the spoil taken away rather than left on the drive.
Everyone has heard the story — the builder who started well, went quiet in week three and left the scaffold up for a year. A programme with real dates, one number that answers, and a payment schedule tied to stages rather than to whoever asks first: that is what separates the two.
Send a photo of the space and roughly what you have in mind on WhatsApp — and your drawings, if an architect has already done them.
A fixed written price broken down by stage, with the weeks it takes and what happens in each one — before anyone lifts a tool.
Built to the drawings, building control signed off, and the site cleared — skips, spoil and all — before we hand it back.
Public-liability insured, with references from regular customers you can check first.
Written start and finish dates by stage, so you can see where the job is instead of wondering.
Structural calculations, drawings and sign-off arranged and dealt with — you are not chasing the council.
One price, paid at agreed stages as work completes. No large sums up front and no creep halfway through.
Extensions, lofts and renovations built across Woolwich and nearby.

Woolwich gives a builder three distinct kinds of house, and each wants a different job. The Victorian and Edwardian terraces running up through Plumstead and Charlton nearly all have the same flaw: a long thin kitchen down one side and a dead strip of yard beside it. Filling that side return is the single best thing you can do to one of these houses — it turns a corridor kitchen into a proper room, and because it sits within permitted development on most of them, it rarely needs planning. What it does need is a calculated steel over the opening, an honest look at the party wall before anyone starts, and a roof detail that does not dump water down the neighbour's flank. Up on Shooters Hill and out through Eltham the stock changes to inter-war semis and the Progress Estate, and the value moves upward: a rear dormer turns unused roof space into two bedrooms and a shower room, usually inside six to eight weeks. On the conservation-area streets the front elevation matters, so we keep dormers to the rear and match tile and render rather than fighting the character. Closer to the river the Royal Arsenal and Kidbrooke flats are newer, and the work there is internal — reconfiguring layouts, opening up living space, upgrading finishes to match what the flat is now worth. Whatever the house, the thing that decides whether a build goes well is not the brickwork. It is the programme. A written stage plan with real dates, structural calculations and building control arranged before the first delivery, one number that answers, and payments tied to completed stages rather than to whoever asks first. That is why we will tell you honestly at the survey if a job needs planning, if the drainage run means a build-over agreement with Thames Water, or if what you actually want is achievable for half the money by reconfiguring what you already have. Fixed staged price, guaranteed in writing, and the site cleared — skips, spoil and all — before we hand it back.

A single-storey rear extension is usually eight to twelve weeks on site; a loft conversion six to eight; a double-storey or a full renovation runs longer. You get a written stage programme with dates before we start, not a vague estimate.
Often not. A great many extensions and rear dormers fall under permitted development, and we will tell you at the survey which yours is. Where planning or a lawful development certificate is needed, we handle the drawings and the application.
Yes — structural calculations, drawings, the building control application and the inspections are all arranged and dealt with. You are not chasing the council, and the job is properly signed off at the end.
Staged, against completed work. A deposit for materials, then payments as each stage finishes to the programme. We never ask for a large sum up front, and the price is fixed unless you change the scope in writing.
Skips and muck away are in the price, and the site is cleared before we hand back. Where a party wall is involved we tell you early, because the notice period runs to two months on most work and it catches people out.
Woolwich based, covering Plumstead, Charlton, Eltham, Shooters Hill, Abbey Wood, Kidbrooke and Blackheath — a builder who can walk the job with you this week, not in six weeks.
