Window Styles

Casement & Flush Casement

One of our most popular products, the casement and flush casement window offers a combination of style, comfort and security.

Hard wearing, low maintenance and tailor made to virtually any specification, casement windows complement any type of home, from modern chic to rustic traditional.



Beautiful and elegant, bay windows are the perfect way to create the feeling of space and maximise light levels in your home.

Choose from a variety of colours in aluminium or UPVC, or if you prefer a more traditional look, you may want to consider timber frames.


If you’ve been putting up with old sash windows that jam or rattle, it could be time to invest in new, secure and energy efficient replacements.

Inspired by classic designs and infused with modern-day conveniences and security features, new sash windows will enhance the character of your home.



Dormer windows are the perfect way to achieve headroom where it might otherwise be difficult.

A Dormer window is a gable window projecting from a sloping roof.  They’re a great way to create extra space with ‘a room in the roof’ and are the perfect solution in single storey homes.


Made from strong, durable materials, tilt-turn windows are modern and practical.  

Simple to use – a quarter turn of the handle opens the top slightly for secure ventilation; while a half-turn allows the window to swing inwards on hinges, enabling easy cleaning. 



Made-to-measure, arched or other shapes offer complete exclusivity where it’s required to create character for your home.

Our made to measure, bespoke windows are available in a range of shapes, styles, colours, finishes and materials.  Just let us know what you need!
