Original references
Existing windows, historic photographs, drawings and nearby buildings can provide valuable design evidence.
Heritage timber windows
Heritage windows shaped around the building, not a catalogue.
Purpose-made timber windows for properties where proportion, original character and planning sensitivity require a more considered response.
Made to order
Reference the original building
Surviving joinery, archive photographs and neighbouring properties can all inform the design.
Made to fit the opening
Bowed, curved and arched shapes
Accoya specialists
Material selected for external joinery
50-year timber warranty
From Accsys, against rot and decay
Sensitive replacement begins with evidence.
The strongest heritage specification is based on the building itself: its period, proportions, surviving details and local planning context.
Farrar can develop bespoke profiles and glazing arrangements around available evidence. The design should then be coordinated with modern glazing, operation and maintenance requirements without making assumptions about approval.

Design principle
Original details should be recorded before replacement decisions are finalised.
Modern requirements handled with visual restraint.
Heritage work often requires trade-offs between appearance, glazing, operation, regulation and planning.
Details developed from the property rather than a generic style.
Available evidence is used to establish proportions, profiles and glazing patterns before technical requirements are coordinated.
Original details recorded
Period-sensitive proportions
Planning context considered

An arched head made to match the existing opening
Heritage specification at a glance.
Each shaped window is made to fit your opening from our standard range of profiles. Whether it is approved for a listed or conservation property rests with your local planning or conservation officer.
Request technical informationConstruction
Purpose-made timber joinery developed around existing details, surveyed openings and the agreed heritage design.
Opening and operation
Opening arrangements are selected to respect appearance while meeting practical ventilation and access needs.
Glazing
Glass is specified around visual sensitivity, planning requirements, safety, thermal and acoustic performance.
Finishes and hardware
Factory-applied finishes and ironmongery selected to complement the property and approved design.
Warranty and maintenance
The Accoya timber carries a 50-year manufacturer's warranty against rot and decay. Factory-applied finishes need a maintenance coat after around eight years on average, and at least every five years in exposed locations.

Accoya is the timber behind the 50-year warranty. These cover how it performs and why it is specified for external joinery.

Initial guidance for homeowners, builders and project specifiers.
We make shaped windows from our standard range of profiles. We cannot change the design to a conservation officer's specification, and listed building consent is a matter for your local authority.
Acceptance varies. The proposed glass, frame dimensions and visual effect should be discussed with the relevant planning or conservation adviser.
Measured details, photographs, surviving original joinery, archive images and clear elevation drawings can all be useful.
No. We make windows and doors from our own standard profiles, which suit many period properties, but we do not make new profiles to copy originals.
