The Barnsbury Group
The Barnsbury Group is a family of heritage joinery and sash window specialists across the UK and Melbourne, led by Barnsbury Joinery in London. Founded 1987.
The Barnsbury Group is a family of heritage joinery and sash window specialists working across the United Kingdom and in Melbourne. It brings together a group of studios and an advisory practice that share one standard of work: timber windows, doors, panelling, staircases and fitted joinery made and restored the way period buildings were originally built. At the centre of the group is Barnsbury Joinery, the flagship London studio, founded in 1987 and based at Low Profile House, 94 Vale Road, London N4 1PZ.
Whether you own a single listed cottage, a Georgian terrace, a Victorian villa or an estate of period property, the group exists to give you one trusted point of contact for heritage work, backed by a studio that still cuts to the original profile. This page explains who the group is, what it specialises in, the companies within it, and which one to contact for your particular need.
Who the group is
The Barnsbury Group is a second‑generation heritage joinery house. It grew out of Barnsbury Joinery, a London studio established in 1987 that built its reputation making bespoke timber sash windows, panelling, staircases, shutters and doors for listed and period properties. Over the decades that reputation drew work from across the country and beyond, and the group took shape as a family of specialist studios able to serve owners, architects, builders and estates wherever they are.
Today the group operates from Barnsbury Joinery's studio at Low Profile House, 94 Vale Road in London N4 1PZ, with sister studios in Hertfordshire, Belfast and Melbourne, and an independent advisory practice for owners who need guidance before any joiner is instructed. Every part of the group answers to the same idea: that heritage timber should be repaired where it can be, replaced only where it must be, and always made to read as original.
The group is trusted on buildings where the standard of work is not negotiable. Barnsbury Joinery is specified by architects and trusted by listed property owners including the Crown Estate and Grosvenor Estate. That level of trust sits behind every studio in the family, because they share the same profiles, the same materials and the same approach to conservation.
What the group specialises in
The group specialises in heritage joinery and sash windows: timber sash and casement windows, timber doors, shutters, panelling, staircases and bespoke fitted joinery for period and listed buildings. This is not off‑the‑shelf window supply. Everything is manufactured by hand and matched to the original moulding profiles, and finished so that new work sits comfortably alongside the old.
Work falls into a few broad areas. Restoration and repair brings tired sashes, rotten cills, broken cords and draughty frames back to full working order, keeping as much original timber as possible. Replacement and new joinery recreates windows, doors and staircases that are beyond saving or were lost long ago, matching what was there before. Bespoke fitted joinery covers panelled rooms, cabinetry, shutters and shop fronts made to measure. Discreet performance upgrades, such as draught‑proofing and slimline double glazing, improve comfort and efficiency without altering the character of the building.
How the group works with you depends on where you are. In London and the South East, the group offers a full service: survey, restoration, repair and bespoke fitted joinery, delivered and installed by its own teams. Across the rest of the United Kingdom, the group supplies made‑to‑measure joinery on a supply‑only basis, so your own builder or installer can fit windows and doors built to the same heritage standard. In Melbourne, Sash Restoration Australia carries the same specialism to Australian period homes.
The companies within the group
The group is made up of five studios and one advisory practice, each with its own focus but all working to the same standard. Below is each one in a line.
Barnsbury Joinery is the flagship London studio, founded in 1987 and based at Low Profile House, 94 Vale Road, London N4 1PZ, making bespoke heritage joinery and sash windows by hand and carrying the parent voice for the family.
Sash Restoration London is the group's dedicated sash window studio for the capital, restoring, repairing and replacing timber sash windows across London's period and conservation‑area homes.
Sash Restoration Hertfordshire brings the same sash window restoration, repair and replacement to Hertfordshire and the surrounding towns, from Hertford and Hitchin to St Albans and beyond.
Sash Restoration Belfast is the group's studio for Northern Ireland, restoring and repairing traditional timber sash windows in Belfast's Victorian and Georgian housing stock.
Sash Restoration Australia is the group's Melbourne studio, restoring and repairing heritage timber sash windows for Australian period properties.
Heritage Window Consultants is the group's independent advisory practice, offering impartial guidance on heritage windows, conservation requirements and the right approach before any work is commissioned.
One group, specialist expertise
The advantage of the group is simple: you get the reassurance of a single, established name and the depth of a studio that does one thing well. Each company is a specialist in its region and its craft, rather than a general builder taking on windows as a sideline. Sashes are the daily work, not the occasional job, and the knowledge that comes from that shows in the finished result.
Because the studios share profiles, materials and methods, the quality is consistent wherever you are. A window restored in Belfast, made in London or fitted in Melbourne is held to the same standard, drawn from the same craft tradition that Barnsbury Joinery has practised since 1987. That shared standard is what holds the group together and what estates, architects and homeowners rely on.
It also means you are never handed off to a stranger. Whichever part of the group you approach first can point you to the right studio for your building and your location, so the enquiry stays inside a family that already knows how to look after period property.
Which company to contact for which need
If you are in London or the South East and want a full service, from survey through restoration, repair or bespoke fitted joinery to installation, Barnsbury Joinery is your studio. It is also the studio for bespoke work such as panelling, staircases, doors, shutters and shop fronts, and for larger or listed projects that need a studio able to make to the original profile.
If your need is specifically sash window restoration or repair, choose the studio closest to you: Sash Restoration London for the capital, Sash Restoration Hertfordshire for Hertfordshire and its neighbouring towns, Sash Restoration Belfast for Northern Ireland, and Sash Restoration Australia for the Melbourne area.
If you are elsewhere in the United Kingdom and want made‑to‑measure heritage joinery to fit yourself or through your own builder, the group's supply‑only service is the route, coordinated through Barnsbury Joinery. And if you are not yet sure what your building needs, or you require impartial advice on conservation and heritage windows before committing to any work, Heritage Window Consultants can guide you first.
How to get in touch
The simplest way to start is to contact Barnsbury Joinery, the flagship studio, which can advise on your project and direct you to the right company in the group. The studio is based at Low Profile House, 94 Vale Road, London N4 1PZ, with opening hours Monday to Friday, 8am to 6pm, and Saturdays by appointment.
For any project involving listed or period property, the best first step is to request a survey. A survey lets the team see the building, understand its condition and history, and recommend the right balance of restoration, repair and new joinery for your situation. From there, the appropriate studio in the group takes the work forward, whether that means our own teams in London and the South East or made‑to‑measure supply across the rest of the UK.
