Every Victorian terrace we're asked to work on has been through at least one previous owner who didn't value what was already there. A cornice boxed in with a false ceiling. A fireplace sheeted over with plasterboard because the chimney was "a nuisance." A picture rail painted so many times it's lost its profile, or stripped out altogether because someone thought it looked old-fashioned. None of this is unusual, and none of it is ruined — it's just waiting to be found again.
Our period property restoration work is mostly this: deciding, room by room, what's worth bringing back, and doing it in a way that holds up rather than looking like a repair. This is how we make that call, and what the actual work involves.
Condition, not age
The question clients ask most is whether something old is automatically worth saving. It isn't, and that's not sentimental hedging — it's the actual test we use. A hundred-and-thirty-year-old cornice that's cracked, waterlogged, and missing half its run is not worth saving in place. The same cornice, dusty and painted over a dozen times but structurally sound underneath, almost always is.
How do I know what's worth saving and what isn't?
By condition, not age. A cornice, a sash, a fireplace surround — if the material is sound underneath whatever's been done to it, it's almost always worth saving. We assess lath and plaster the same way we assess everything else behind a wall: by tapping it, not by guessing from how old it looks. We've written in more detail about what we actually find behind a Victorian wall once it's opened up, including how we read lath and plaster that's a century old.
Cornices and picture rails
Where a cornice has been boxed in, plastered flat, or removed outright, we take a profile from the nearest surviving section — another room, a neighbour's house, sometimes a single surviving length behind a later partition wall — and have it run to match in a plaster specialist's workshop. Fitted properly, the join is invisible. A picture rail is a smaller job with the same logic: the profile is matched, mitred at the corners, and fixed at the height the room was designed around, not wherever looks convenient now.
Can you match an old cornice in a single room?
Yes. We take a profile from a surviving section, have it run in plaster by a specialist, and fit it to match. The repair is invisible.
Fireplaces
A sheet of plasterboard over a chimney breast is one of the most common things we open up and find, usually dating from a decade when a working fireplace was treated as a maintenance problem rather than a feature. Behind it is almost always the original opening, sometimes with the grate and surround still in place, sometimes stripped back to bare brick by whoever boarded it. Where the surround survives, we restore it. Where it doesn't, we fit one that suits the room's period and scale rather than picking the first reclaimed piece that happens to fit the opening — a fireplace that's the wrong proportion for the room reads as wrong even to someone who couldn't tell you why.
Sash windows
Sash windows are the one original feature clients most often arrive wanting to replace rather than restore, usually because a previous builder or a double-glazing salesman has told them the originals are draughty, rotten, or not worth the money. Almost none of that holds up once we've actually opened a sash up.
Should I refurbish or replace sash windows?
Almost always refurbish. Original sashes are made from old-growth timber that has lasted a hundred and forty years and will last another hundred if treated well. Refurbishment is also cheaper than replacement.
The actual process: the sashes come out, the frame and glazing bars are cleaned back, any rot is cut out and replaced with new timber spliced in rather than filled over, the whole thing is repainted, and draught-proofed with a discreet brush seal let into the frame before it's rehung on new cords and weights. On Devonshire House, the living room sashes were refurbished rather than replaced as part of a whole-house programme that also reinstated the original skirting profile and ran the hallway's herringbone parquet straight through into the room — the kind of continuity that only survives when the original fabric is kept rather than swapped out room by room.
Lath and plaster, where it's worth keeping it
Original lath and plaster ceilings and walls are often assumed to be a liability the moment a renovation starts, and sometimes they are. But a sound lath and plaster ceiling has a depth and a slight irregularity that a flat sheet of modern board doesn't reproduce, and it's worth keeping wherever it's actually sound. We test it by tapping across the surface: a solid return means the key between plaster and lath is intact; a hollow sound means it's already failed and re-skimming over it will only crack again within a year or two. Where it's sound, we repair small areas and leave it. Where it's genuinely gone, we replace it rather than pretend otherwise.
Where permission comes into it
Most of this work happens inside the house and doesn't need planning consent. The exceptions are the features visible from the street — a sash on the front elevation, a front door, render or paint on a façade in a Conservation Area — which is a planning matter in most of the postcodes we work in.
Does restoring original features need planning permission?
Usually not for work inside the house. In a Conservation Area or on a Listed Building, some of it — particularly anything visible from the street — does need consent, and we check before we start work that needs it. The fuller picture of what does and doesn't need permission is in our guide to planning permission for a Victorian terrace. Where the feature in question is the whole front elevation rather than a single room, we've also written about restoring a Victorian front elevation in full.
What it costs, and how long it takes
Standalone period restoration work — a room's worth of cornice and picture rail, a set of sashes, a fireplace brought back — typically starts from £25,000 and runs to two or three months depending on scope, and often sits inside a wider renovation rather than standing alone. The fuller picture of where that fits inside a whole project is in our guide to what a renovation actually costs in East London.
None of this is about nostalgia for its own sake. A house that's kept its cornices, its sashes, its fireplaces, and its lath and plaster where it was sound simply has more in it — more detail, more texture, more of the thing that made someone want a Victorian terrace rather than a new-build in the first place. The work is making sure that's still true after we've been through it.
