Islington has one of London's finest stocks of Georgian and early-Victorian terraces — and they need restoring with knowledge. TrustBuilt Projects restores period and listed houses across Barnsbury, Canonbury and Highbury (N1, N5, N7).
Islington's Georgian and early-Victorian terraces — concentrated in Barnsbury, Canonbury, Duncan Terrace and the garden-square streets — are among the best preserved in London, and much of the stock is listed and within conservation areas. Restoration here is about respecting flat-fronted brick elevations, fine joinery and original sash windows.
The typical Islington period house is London stock brick rather than stucco, so the external work centres on sensitive repointing, brick repair and sash window restoration — using lime mortar and matching brick, never hard cement pointing that damages soft historic brick. Internally, we restore cornicing, shutters, panelling and original floors.
Because so much of the borough is sensitive, we lead with conservation and (where needed) listed building consent. We advise on the right approach at survey stage and carry out the works to a standard that satisfies the conservation officer and protects the house's value.
Period restoration in Islington is bespoke; brickwork condition, listed status and interior scope drive the figures. As a guide:
| Project type | Typical cost | Timeline |
|---|---|---|
| Sash window restoration (per window) | £600 – £1,300 | by programme |
| Brick repointing (lime mortar) | £6,000 – £30,000+ | varies |
| Full period interior restoration | from £110,000 | 16–30 weeks |
| Whole-house listed restoration | POA | 6–16 months |

Yes — Islington's Georgian and Victorian houses are built in soft London stock brick that needs lime mortar. Hard cement pointing traps moisture and accelerates erosion of the brick face, so lime repointing is both the correct heritage method and what the conservation officer expects.
Yes, and in Islington's listed and conservation streets it's usually required rather than replacing them. We splice and repair the timber, overhaul the box-sash mechanism and draught-proof for performance without altering the appearance.
Yes — much of Barnsbury and Canonbury is listed. We work within listed building consent, coordinate the heritage statement, and use traditional materials and methods throughout to protect the original fabric.
We survey the building's condition thoroughly, agree the scope with you, then issue a written quote. The figures above are a guide — listed status and the extent of brick, plaster and joinery work move the real cost.
