Whatever the concept of your new extension, roof lights, lanterns and windows are now available in such a wide range of designs that there is sure to be a style to fit your space.

The aim of a roof light is simple – to bring as much light to a space as possible – but there’s a few things that need to be considered along the way that will affect not only the aesthetic value of your project, but the budget too.

Bespoke or off-the-shelf?

Choosing a roof light that is a standard size is the route to a more cost-effective build, and in many instances is totally appropriate for the design, even if you need to get creative with how you use them.

However, if every centimetre matters in your design, or you’re looking to use glass roof windows in a more unusual or challenging way in your design, you may have to bite the bullet and incorporate the cost of a bespoke creation into your project budget.
