Light is one of the biggest drivers of how spacious and valuable a home feels.

Natural light is the secret ingredient that makes a home feel spacious, welcoming and valuable. Many London homes are darker than they need to be, and a renovation is the perfect opportunity to fix that. Here is how to maximise it.

Bring in light from above

Rooflights and roof lanterns are the most effective way to light the centre of a room or a deep extension, because overhead light reaches far further into the plan than side windows. A lantern over a kitchen-diner or rooflights along a flat roof transform a dark rear space into a bright one.

Glaze the rear

Large glazed doors to the garden, and a glazed roof over a side return, flood the back of the house with light. This combination is why open-plan kitchen-diner extensions feel so bright and is one of the most popular reasons to extend.

Borrow light between rooms

Internal glazing and Crittall-style screens let light pass between rooms, brightening dark middle rooms and hallways while keeping spaces defined. Opening up walls into an open-plan layout lets light travel further still.

Amplify what you have

Finally, make the most of the light you bring in: pale, reflective finishes, well-placed mirrors, and considered lighting for when daylight fades. Light is one of the biggest drivers of how spacious and valuable a home feels. To design light into your renovation, contact us or call 07472 424 226.

Frequently Asked Questions

How can I get more natural light into my house?

Bring in more light with rooflights and roof lanterns over deep or rear rooms, large glazed doors to the garden, a glazed side return extension, internal glazing or Crittall-style screens to borrow light between rooms, and light, reflective finishes and mirrors. Removing or opening up internal walls also lets light travel further through the plan.

Do rooflights make a big difference?

Yes. Rooflights and lanterns deliver overhead daylight, which is far more effective than side windows at lighting the centre of a room or a deep extension. Because the light comes from above, it reaches further into the plan and stays bright through the day, transforming dark rear kitchens and dining areas.

How do you light a dark middle room?

Dark middle rooms, common in London terraces, are best brightened with rooflights where the room is single-storey, internal glazing or glazed doors that borrow light from adjacent brighter rooms, opening up walls into a lighter open-plan layout, and pale reflective finishes. A glazed link in a side return can also feed light through.

Does natural light add value?

Light strongly influences how spacious, welcoming and valuable a home feels, and it is one of the first things buyers respond to. Bright, light-filled rooms consistently show and sell better than dark ones, so improving natural light is one of the most effective, if sometimes overlooked, ways to enhance a home.

What is the best way to add light to an extension?

The best-lit extensions combine large glazed doors to the garden with rooflights or a roof lantern over the new space, and often a glazed link where the extension meets the original house. This layering of overhead and garden-facing light is what makes open-plan kitchen-diners feel so bright.
