Things to Consider with a Flat Roof Extension with a Roof Lantern
Classic or Contemporary Design?
One of the first decisions you’ll need to make when planning your flat roof lantern extension is the overall design style.
Whether you lean towards a classic look or prefer something more contemporary, a roof lantern can complement both.
Korniche roof lanterns, for instance, offer sleek, modern designs with slim frames that maximise light entry while maintaining a minimalist aesthetic.
On the other hand, more traditional roof lanterns might feature more ornate details, blending well with period properties.
How Much Natural Light Do You Want to Let In?
The main appeal of adding a roof lantern to your flat roof extension is the ability to flood the space with natural light. Consider the orientation of your home and how the sunlight moves throughout the day.
A larger lantern will let in more light, but you’ll need to balance this with energy efficiency, as too much sunlight can lead to overheating, especially in summer.
What Shape Do You Want?
Roof lanterns come in various shapes, and the one you choose will impact both the look and feel of your extension.
The most common shapes are rectangular, but square and octagonal designs are also available.
Rectangular lanterns are ideal for larger spaces and can create a grand, linear look. Square or octagonal lanterns might be more suited to smaller extensions or spaces where a focal point is needed.

What Size Lantern Do You Want?
The size of your roof lantern should be proportionate to the size of your extension. If the lantern is too small, it may not make much impact, while an oversized lantern might dominate the space.
Measure your extension carefully and consult with a specialist to ensure the lantern size is perfect. Additionally, consider the height of the room—higher ceilings can accommodate larger lanterns, creating a dramatic effect.
What Permissions Will You Need?
Before installing a flat roof extension with a roof lantern, it’s essential to check whether you need planning permission.
Generally, adding a roof lantern to a flat roof doesn’t require planning permission, as long as it meets specific criteria, such as not exceeding a certain height above the existing roof.
However, if your property is listed or in a conservation area, you may need additional permissions. Always check with your local planning authority before proceeding with your project.
