Let in the light
If you’re extending your home or renovating a flat roof, there’s no better way to transform the space than with a roof lantern or flat skylights.
Designed to draw in natural light and create an airy, open feel, it can make any kitchen, dining area or living space feel bigger, brighter and more inviting.
We supply and install roof lanterns in Chessington and across Surrey, all precision-engineered, energy-efficient, and built to impress.
What’s the difference?
Roof lanterns
are pitched, architectural features that sit proud of a flat roof, bringing in daylight from multiple angles.
Flat Skylights
sit flush or low-profile, offering a sleek, modern look without changing your home’s external silhouette.
Bring Light & Space to your Home
Both options can dramatically enhance the look and feel of your home especially in
single-storey extensions, garden rooms, or over conservatories and orangeries.
