Casement Windows

Our traditional hinged casement windows are the result of over 30 years of innovation and product refinement. Using superior quality solid hardwood, our skilled craftsmen use traditional joinery methods to create a window that marries premium performance with bespoke designs that remain sympathetic to the original features of your character or period property. Incorporating only the finest materials, craftsmanship and finishes, our casement windows are designed to delight every time.



Our range of bespoke casement windows features double glazed safety glass as standard but can be tailored to your exact requirements, incorporating other glazing styles and specifications such as toughened and laminated glass, acoustic glass, and textured, obscured or stained glass.


All of our traditional timber windows feature authentic moulding that will perfectly complement your property. Our internal mouldings are created bespoke to match the original mouldings in your home, while outside detailing such as glazing bars are matched to existing features.


All of our casement windows can be finished in the exact shade of your choice. We use high pigment, resin-rich microporous paint including those by British paint experts Farrow & Ball, renowned for their beautiful, premium quality paints and stunning, unmatched shades since 1946.

Ironmongery and Opening

Our traditional casement windows come with a choice of brass, copper, black, chrome and satin chrome fittings, with bespoke fittings available on individual specification. We use classic standard hinges, and our casement windows can be side hung, top hung or in French or false mullion style.
