Timber Windows and Doors for Architects

Specification support, technical data and DWG library

Spittlywood designs and manufactures bespoke timber windows and doors to your specification, built in our Kent workshop on precise CNC machinery. The result is joinery that matches the approved drawings unit for unit, so what you specify is what gets installed.

We work alongside architects and specifiers on contemporary, period and listed projects, supplying the performance data, drawings and compliance evidence you need to specify with confidence.

From first enquiry to delivery, our technical team is on hand to help with glazing selection, hardware, sightlines and planning requirements.

Built to Your Specification

Every window and door is made to order across our full Lignum range: casement, sash, stormproof and alu-clad windows, plus entrance, French, bi-fold and lift and slide doors. Glazing options run from double and triple to vacuum and slim heritage units.

Computer-controlled machining gives consistent, accurate components, so frames, sashes and door leaves meet strict standards for security, thermal efficiency and longevity across the whole order.

We can supply only, or supply and install across the South East, and we coordinate with your contractor on site.
