Builders inCrystal Palace.

On the ridge streets of SE19 the ground rarely does what the drawing assumes. Gardens step up or fall away from the back wall, so a rear extension here starts with levels: stepped foundations where the site slopes, retained ground where it doesn't, and a decision about whether the new kitchen floor meets the garden or the house. Handled well, the slope becomes the best thing about the room — a garden-level kitchen-diner under a run of glazing that faces the afternoon sun the ridge is known for.

Structurally the work is familiar Victorian territory: a steel picking up the original rear wall, the outrigger absorbed into the new plan, and party-wall notices served on both sides where the house is mid-terrace. Which council grants consent depends on where the street sits — several borough boundaries converge near the Triangle — and we confirm the correct authority at the first survey rather than guessing from the postcode.

The double-fronted villas and wider semis between Church Road and the park edge take more than a single-storey addition. A house extension at that scale usually pairs a two-storey rear or wraparound build with a reworked ground floor, and often a loft conversion in the same contract, so the scaffold goes up once and the disruption happens in one continuous programme instead of three separate years of it.

We run these as whole-house projects: one project manager, a written sequence of trades, and the family usually still living in the building while the work moves room by room.

This is the highest ground in south London, and the frontages pay for it — wind-driven rain finds every crack in the stucco mouldings and every joint the last builder pointed in hard cement. Facade restoration on the 1880s and 1890s stock means cutting out blown render rather than skimming over it, repairing bay mouldings and window surrounds in compatible lime-based material, repointing in lime mortar so the brick can breathe, and finishing in a masonry system chosen for the exposure rather than the colour chart.

Done properly it is a once-a-generation job, not a repaint every five years.

A large share of Crystal Palace's villas were divided into flats decades ago, and their bathrooms and kitchens now sit oddly against the original fabric — soil stacks in strange corners, kitchens in what was a bedroom. We refit both, working with the existing stack positions where they make sense and moving them where they don't, and we handle the freeholder consent paperwork conversion flats usually need before work starts. Boiler replacements are carried out through our Gas Safe registered partner, typically swapped within the same programme as the room they serve.
