My name is Justin Dethier, I trained as a traditional bench Joiner over 20 years ago, before establishing Workshop409 in 2012, in Virginia Water, Surrey. I Craft high-quality, custom-made windows, doors, staircases, and furniture and many other interesting projects, blending traditional craftsmanship with modern techniques, ensuring each piece is built to last.

I take pride in sourcing sustainably and ethically, using both reclaimed and responsibly sourced timber for all my projects. Whether restoring period features or creating something entirely unique, I bring an exceptional level of skill and attention to detail to every job. From intricate period door and window restoration to one-of-a-kind bespoke furniture, Workshop409 is committed to making your vision a reality.
