A hand-crafted luxury.

Exquisite hand-made carpentry, with an attention to proportion and accuracy of detail that allows us to faithfully replicate the simple grace of traditional period windows in your property.

An extensive range. Whether you require sash, tilt-and-turn or casement windows, allow us to take you through our products to establish your needs. We also manufacture front, French and bi-folding doors to your exact specification.

A beautiful material. Wood is luxurious in both appearance and its strength, however with prolonged contact with water the moisture can cause warping, the movement of the warp goes in the direction of the grain. This characteristic has been used to create a highly durable and rigid material. By layering sections of wood with the grain laying in different directions it opposes any twisting or warping.

A bespoke colour palette. Not only are we able to specify any colour contained within the industry's RAL spectrum, if you're looking for finishes to complement the interior and exterior surfaces of your build, we can apply separate colours inside and out — for a dual-colour effect. We're also able to provide an exclusive range of Farrow & Ball and Fired Earth paint finishes for you to choose from.

  • We are very pleased with our replacement windows. Our original stained glass windows were incorporated into uPVC frames giving us the look of our old windows but the efficiency of new, energy-saving windows.

  • From salesman to the fitting team it has been a very pleasant experience. We have had a couple of minor adjustments made a month or so after installation. The speed and quality of the follow up was first class.
