Timber windows

Sliding sash windows, made with period character and modern assurance.

Bespoke timber sash windows designed around the proportions of the building, combining traditional visual character with carefully considered glazing, finishes and operation.

The character of a sash window lives in the details.

A successful replacement should preserve the rhythm and refinement of the elevation rather than appearing visibly heavier or newer.

Meeting rails, glazing bars, horn details, cills and frame sightlines all affect the result. Farrar's purpose-made approach allows those elements to be reviewed together instead of forcing the property around a standard size.

Design principle

The whole elevation should be reviewed before individual openings are finalised.

Shape the sash window around the property.

The choices below should be coordinated as a single design rather than selected independently.

01

Glazing patterns

Pane divisions and glazing bars can be developed around the age, style and proportions of the elevation.

02

Sash proportions

Meeting rails, visible frame widths, horns and cill details influence how light or heavy the window appears.

03

Opening arrangement

The operating system and opening requirements should be selected around use, access and the desired visual result.

04

Colour and ironmongery

Factory-applied finishes and coordinated hardware complete the window and should complement the surrounding architecture.

Period character with present-day expectations.

Appearance, weather performance, glazing and operation must be considered together. The final specification is developed around the building rather than a generic product label.

Sightlines that feel appropriate to the building.

The relationship between the frame, meeting rails and glazing pattern is reviewed across the elevation so replacement windows remain visually coherent.

Project case study

Period-window replacement without losing the elevation.

A genuine case study explaining the project rather than presenting photography without context.

Property Period residential home
Requirement Replacement sash windows
Design focus Sightlines and glazing patterns

Challenge

Improve comfort and operation while avoiding replacement frames that appeared too heavy for the existing openings.

Approach

Review the complete elevation, use surviving details as a visual reference and coordinate glazing bars, meeting rails, finish and hardware.

Outcome

A more coherent replacement scheme that respects the architectural rhythm while introducing a modern joinery specification.

Questions about sliding sash.

Initial guidance for homeowners, builders and project specifiers.

Purpose-made manufacturing allows frame dimensions, meeting rails, glazing patterns and other details to be developed around the property.

Glazing options can be considered alongside frame sightlines, weight, safety, thermal and acoustic requirements.

They may be, but acceptance depends on the property, local guidance and the proposed details.

Photographs, approximate dimensions, elevations, quantities, location and any known planning requirements are useful starting points.
