Bespoke Timber Window Design

Bespoke timber windows are manufactured to your specific requirements whether it’s for a new build, renovation or a listed building project. Our experienced joiners will manufacture your windows where required to replicate all the intricate detail and design of existing joinery such as heritage windows in conservation areas. Options include a range of hardwoods, mouldings, curved headers, solid or face applied glazing bars and an attractive collection of ironmongery.

Our windows are manufactured in quality hardwoods such as Sapele and European Oak from Sustainable forests. We also manufacture in Accoya, a modified wood with exceptional performance and durability. Your windows can be finished to any RAL colour using our microporous paint system. PAS24 security enhanced windows are available to help protect your property, whilst also meeting energy-efficiency and weather performance standards. 


Quality Standards for Timber Windows

Our timber windows are manufactured to BS EN 14351-1, UKCA marked and pre-glazed in compliance with building regulations. We offer a 10 year warranty for fully finished windows. 

To ensure the quality of our windows we undertake bi-annual quality audits through independent examiners. Our PAS24 windows and doors have been awarded the CMS gold quality standard.
