Roof Lanterns for Extensions & Kitchens
Transform dark extensions and flat-roof renovations with high-performance roof lanterns that maximise natural light, increase perceived space, and elevate your home’s architecture.
The Science of Light: Beyond Vertical Glazing
Light entering from above is significantly more effective at brightening a room than light entering through traditional vertical windows. Because the glazing is angled toward the sky, it captures sunlight throughout the day, eliminating shadows in the corners of large open-plan kitchens or dining areas.
Spatial Volume and the “Upward Extension”
A roof lantern breaks the horizontal plane of a flat roof, extending the sense of space upwards. This architectural “void” draws the eye toward the sky, creating a feeling of openness and volume — and for homeowners in Windsor and Maidenhead, adding this vertical dimension can significantly increase the “wow factor” and market value of a home.
Architectural Elegance: Aluminium vs. uPVC Systems
We provide both uPVC and aluminium systems, each offering distinct advantages. Aluminium roof lanterns are engineered with exceptionally slim sightlines — more glass and less frame, for an unobstructed view of the sky. Every installation features advanced weather-tight sealing, and powder-coated aluminium frames resist corrosion and fading for years to come.
Thermal Performance and Year-Round Comfort
Low U-Values
Thermally broken frames and argon-filled double glazing retain heat during colder months.
Solar Heat Reflection
High-specification glass reflects up to 83% of solar heat, preventing summer overheating.
Self-Cleaning Options
UV coating breaks down organic dirt, washed away by rainwater — minimal maintenance.
The Psychological Impact: Biophilic Living
Increased exposure to natural daylight helps regulate sleep patterns and improves mood and productivity. A roof lantern provides a live view of the changing sky — whether it’s the movement of clouds, the sound of rain on the glass, or a clear view of the stars at night — making the room feel “alive” and connected to the outdoors.
Case Study: A Transformation in Beaconsfield
Challenge
A homeowner in Beaconsfield had completed a large flat-roof extension for a new luxury kitchen. Despite side windows, the centre of the room felt dim and disconnected.
Solution
We designed and installed a bespoke 3-metre aluminium roof lantern with neutral self-cleaning glass and ultra-slim rafters to match the existing aluminium windows and doors.
Result
The kitchen was instantly transformed — natural light now reaches the island throughout the day, with a significant reduction in electric lighting use.
Frequently asked questions
Do roof lanterns require planning permission?
In most cases, roof lanterns fall under “Permitted Development” as long as they do not protrude more than 150mm above the highest part of the roof. We always recommend checking local regulations, especially in conservation areas.
Are they easy to clean?
Many of our lanterns come with self-cleaning glass options that use UV rays to break down organic dirt, which is then washed away by rainwater.
How secure are they?
Our lanterns use toughened safety glass and internal glazing beads, meaning the glass cannot be removed from the outside — excellent security for your home.
