How to Add Natural Light to Your Extension with VELUX Windows
If you’re working on an extension, whether it’s out the back, up in the loft, or somewhere in between, there’s a lot to think about. Layout, flooring, electrics… the list goes on. But one thing that makes a massive difference and often gets overlooked? Natural light.
Good daylight can transform a property in a big way. It makes rooms feel bigger, brighter and, let’s be honest, just better to be in. When windows on the walls aren’t enough (or even possible), VELUX roof windows are a brilliant way to bring in light from above.
They work for both flat and pitched roofs. So whether you’re building out or up, there’s options that’ll suit your property.
Starting with Velux Windows For Flat Roof Extensions
Flat roofs are common for rear extensions and often used in more modern builds. They’re practical, simple, and look clean from the outside. But without enough thought, the inside can end up a bit gloomy, like a very stylish cave.
That’s where flat roof VELUX windows make a big difference. They bring in loads of daylight while keeping that clean, minimal roofline intact.
A few options worth looking at:
- Flat glass rooflights – Neat, low-profile, and great if you like a modern finish.
- Curved glass versions – These help rainwater run off and bring in more light from different angles (handy if the sun never quite gets its act together).
- Domed rooflights – Ideal for spaces that tend to feel dark, especially on overcast days (so, basically… most days in Essex).
- Models with ventilation – Useful in kitchens, bathrooms or utility rooms where air can get a bit steamy.
Pitched Roof Velux Windows: Lofty Ideas and Classic Style
There are a few different styles to choose from:
- Top-hung windows – Open outwards, great if you want clear views and a more open feel.
- Centre-pivot windows – Easy to use, even when positioned higher on the roof. The pivoting mechanism makes them simple to open and close, and they’re a practical choice for rooms where the window isn’t within direct reach.
- Combinations – You can pair windows together for a bigger burst of daylight. Good for long, narrow spaces or when one just isn’t enough.
Pitched roof windows are especially useful in lofts where traditional windows can be tricky to fit, or where privacy’s a concern and you’d rather not make eye contact with the neighbour while brushing your teeth.
A Few Things to Think About First
Which direction does the roof face?
South-facing roofs get more sunlight, so you might not need as many windows. North-facing? You’ll want to go bigger, or add a few more to get the same effect.
How will the room be used?
Living areas might need soft, even lighting. Kitchens and bathrooms? Better with windows that open, unless you enjoy cooking in a sauna.
Any privacy issues?
If neighbours can see onto your roof, consider positioning, glazing options or adding blinds. Nobody wants to be the accidental star of the street’s group chat.
Planning permission?
Some roof windows are fine under permitted development, but not always, especially in loft conversions. It’s always safer to check whether planning permission is required for roof windows, than to start explaining things to the council.
It's Not Just About Light - It's About Feeling
Light from above feels different to light from the side. It’s softer, more even, and changes as the day goes on. Morning light in the kitchen, warm golden tones in the evening, natural daylight creates moods that electric bulbs just can’t copy (no offence to your downlighters).
Roof windows don’t just brighten the space, they shape how it feels. They make small rooms feel bigger, and quiet corners feel more open. And with so many different styles, finishes and sizes, there’s usually something that fits your project perfectly without standing out for the wrong reasons.
Quick Recap
For flat roofs:
- Sleek, modern rooflights
- Curved or domed options for more light
- Great for central parts of the room
For pitched roofs:
- Easy-to-open centre-pivot or top-hung windows
- Ideal for lofts, side returns, and upstairs spaces
- Can be combined for more impact
