Est. 1993 — In-House Design to Installation

Bespoke Timber Windows & Doors, London


Designing, manufacturing and installing bespoke timber windows and doors since 1993. Everything in-house - from measured survey to factory finish to your front door.

01 - Heritage

Three decades of bespoke craftsmanship


What started as a family workshop in 1993 has become one of the most respected timber window and door specialists. We still do everything ourselves - and that's precisely the point.

01

Family-Run Since 1993

Over thirty years of heritage. Not a franchise. A family that takes pride in every window that leaves the workshop.

Designed & Built In-House

Survey, design, manufacture, installation - everything under one roof. No outsourcing. No compromises. Complete quality control.

03

Conservation Specialists

Grade II listed buildings and conservation areas demand expertise built over decades. We've earned ours.

03 - Craftsmanship

From measured survey to factory finish - under one roof


Most companies outsource at least one stage. We control every step - because when you're working on a Grade II listed property, there's no room for broken telephone.

05 - Testimonials

Trusted by homeowners across the South East


The attention to detail on our Grade II listed property was remarkable. Every sash window is historically accurate yet thermally efficient. The conservation officer approved everything first time - that speaks volumes about their expertise.

James Harrington

12 box sash windows - Victorian terrace · Richmond, London

We commissioned both sash windows and a bespoke front door. The fact that one team designed, built and installed everything meant there was absolute consistency in the finish. Three years on, they still look flawless.

Eleanor Whitfield

Full window & door programme - Georgian townhouse · Marlow, Buckinghamshire

Our architect recommended Sash Bespoke for the bi-fold doors after seeing their work on another project. The engineering precision and the quality of the Accoya timber is genuinely a cut above anything else we considered.
