A gloomy room can affect your mood and make your home feel uninviting. Thankfully, there are many ways to increase natural light for a more welcoming space.
In this guide, we’ll explore how to get more light into your space, with a focus on the ways our rooflights and skylights can help.
What makes some rooms so dark?
Several factors can cause a room to feel dark. Most often, it’s due to a lack of natural light.
The room may have small or no windows or be north-facing and therefore not benefit from direct sunlight. Thick foliage or buildings outside can also block whatever daylight is available.
Interior elements play a role too; dark-coloured walls or floors absorb light, and heavy curtains or bulky furniture might obstruct windows.
Low-wattage bulbs or single light sources can leave corners in shadow. Even clutter can make a space feel cramped and dim by blocking light pathways.
How to brighten up a dark room: 20 effective ways
Below are 20 practical tips to help. These suggestions blend interior design ideas with more quick and easy fixes.
Implementing several of these in combination will give you the best results in brightening your dark room.
1. Install a skylight or roof window
When a room has limited wall windows, one of the most impactful solutions is to add a skylight or roof window. Skylights bring in natural light from above, flooding the space with daylight throughout the day. A well-placed roof window can often deliver more light than a similarly sized vertical window, because it captures light from the sun across a wider range of angles.
At Toughened Glass Systems, we offer a range of skylights and roof windows to suit different homes. This includes flat roof windows and roof lanterns, as well as bespoke features tailored to the room in question. This includes:
- Bathroom Skylights
- Conservatory Rooflights
- Bedroom Skylights
- Kitchen Skylights

2. Paint walls and ceilings in light colours
One of the biggest changes is to repaint dark walls with a lighter hue. Whites, creams, pastels or light greys all reflect far more light than deep, saturated colours.
A fresh coat of pale paint on the walls (and don’t forget the ceiling) will bounce available light around the room, instantly making it feel brighter and more open.
If you’re not a fan of plain white, even soft neutrals or cool pale blues can work wonders in increasing brightness.
3. Opt for light or sheer window treatments
Thick curtains and dark curtains can make a dim room feel like a cave. Swap them out for lighter, sheer window treatments that allow sunlight to filter through.
Sheer or voile curtains, translucent blinds, or light-coloured linen curtains will maintain privacy while letting much more daylight in. During the day, keep them drawn open as much as possible to boost incoming light.
By contrast, heavy blackout curtains should be reserved only for nighttime if needed. The more of your window that’s exposed to the sky, the brighter your room will be.
4. Choose light-coloured furniture and decor
Dark upholstery, rugs, and furniture can weigh a room down. To brighten the space, decorate with light furniture and accents.
For example, a sofa in a pale neutral fabric or a white bookcase will reflect light instead of absorbing it. If replacing large furniture isn’t feasible, you can add light-coloured slip covers, bright pillows, or a duvet in a bedroom.
Even swapping out dark lamp shades for white ones can help spread light more effectively.
5. Lay down a bright rug
Floors are a huge surface area, if yours are dark wood or covered in a dark carpet, they might be contributing to the gloom. Placing a light-coloured rug can help bounce light onto the walls and lighten the overall look.
For instance, a white, beige, or pastel rug (or a natural light-toned jute rug) breaks up the dark flooring and provides a reflective surface for both natural and artificial light.
6. Hang mirrors to reflect light
Using mirrors can make a dark room look brighter and larger. Mirrors don’t create new light, but they reflect existing light around the space.
Hang a large mirror on a wall opposite a window or lamp to bounce light across the room. Floor-to-ceiling mirrors or mirrored closet doors are particularly effective at adding light.
Toughened Glass Systems also offers custom-cut mirrors, which can be suited to fit your space perfectly.
7. Decorate with reflective surfaces and finishes
Metals like silver, gold, or chrome, as well as glass or crystal items, and glossy finishes on furniture, can all help scatter light.
For example, you might use brass or chrome light fixtures, a shiny metallic vase, or a high-gloss lacquered tabletop.
These subtle touches create a sparkle effect that makes the room feel more luminous. Just be careful to balance it, so the room still feels cohesive and not overly shiny.
8. Pick glass or Lucite furniture to reduce bulk
Solid, bulky furniture can cast shadows and block light from spreading. In a dark room, it helps to lighten the furnishings visually. One clever approach is to use glass or acrylic (Lucite) furniture for key pieces.
A glass coffee table or transparent acrylic chairs, for instance, allow light to pass through so they practically “disappear” in the space.
9. Incorporate greenery for an airier feel
Interestingly, adding a bit of greenery can make a room feel brighter and more lively. While plants don’t increase light, they bring life and a sense of freshness that combats a gloomy atmosphere.
A few well-placed houseplants, especially those with bright green foliage, can psychologically lift a space, making it seem more natural.
10. Clean windows and glass surfaces
Sometimes the easiest solution is also the most overlooked: give your windows a thorough cleaning. Dust, dirt, and grime on windows drastically cut down on incoming light, even moderately dirty windows might block around 20% of daylight.
By cleaning the windows (inside and out), you allow more sunlight to come in. While you’re at it, wipe down any glass doors, mirrors, and light fixtures because dust on these can dull their brightness, too.
This simple task can make a noticeable difference in how bright your room feels. Learn how to clean glass windows without streaks in our guide.
11. Rearrange furniture to unblock light
Have a look at your room’s layout with fresh eyes. Is any large furniture inadvertently blocking a window or lamp? Placing a bookcase in front of a window, for example, can rob a room of natural light.
Rearrange your furniture to make sure that light sources are not obstructed. Move tall pieces away from windows and keep pathways for light open.
You might pull sofas away from walls or reposition tables so they don’t cast shadows where you spend time.
12. Declutter and maximise open space
Piles of items, too much furniture, or crowded shelves create visual noise that absorbs light and creates dark spots. Take time to declutter your room, clear off surfaces, and organise or store away excess items.
A tidy, open room allows light to disperse without being trapped behind stacks of stuff.
Use smart storage solutions to tuck things out of sight (boxes, baskets, cabinets) while keeping the room’s visible area as open as possible.
13. Layer your lighting with multiple light sources
If a room lacks natural light, creating a warm, well-distributed lighting scheme is key. Relying on a single overhead fixture will leave the corners and lower areas in shadow.
Instead, layer your lighting: combine ambient lighting (ceiling lights or wall lights) with task lighting and accent lighting (such as small lamps, sconces, or LED strip lights in shelving).
14. Use high-lumen or daylight LED bulbs
The type of light bulbs you use can dramatically affect a room’s brightness. Old incandescent or low-wattage bulbs might be casting a dull yellow hue.
Swap them out for modern LED bulbs with a high lumen output (brightness) and a daylight or cool white colour temperature.
Daylight-mimicking bulbs emit a clearer, whiter light that can lift a dim room’s atmosphere, especially in spaces with little natural light. They also use less energy for the brightness they provide.
15. Use internal glass doors or partitions
If your dark room is enclosed by solid doors or walls, consider replacing some of those surfaces with internal glass doors or partitions. For example, swapping a wood interior door for one with frosted or clear glass panels will allow light to flow from adjacent rooms.
Glass partitions (or even internal windows between rooms) maintain an open, light-sharing feel while still dividing the space.
This concept of “borrowed light” can make a huge difference for windowless areas like internal hallways, box rooms, or home offices that adjoin brighter rooms.
16. Add glass patio doors or larger windows
Perhaps the room is dark because it only has a small window (or none at all on an exterior wall). In this case, you might look at increasing the size of the opening to bring in more light.
Replacing a solid exterior door with glazed French doors or sliding patio doors will dramatically brighten a room by merging it with the outdoors.
Likewise, if feasible, enlarge an existing window or add an extra window to boost sunlight entry. Modern glass doors essentially act as floor-to-ceiling windows, flooding interiors with daylight and views.
17. Choose slimline glazing for windows and doors
When upgrading or installing new windows and doors, pay attention not only to the glass size but also to the frames.
Thick, chunky window frames can block a portion of the light. Opt for slimline glazing systems, modern designs with slim, minimal frames that cover the most glass area.
18. Trim trees and outdoor obstructions
Sometimes the issue isn’t the room itself, but what’s outside of it. If you have large trees, thick shrubs, or even exterior structures shading your windows, they could be greatly reducing the natural light available.
Consider trimming back outdoor foliage or repositioning outdoor elements that block your windows. Even cleaning the exterior (e.g., overhanging eaves or gutters that darken the top of the window) can help.
Of course, do mind local tree preservation rules and your landscaping goals; the idea is to strike a balance between greenery and light.
19. Add interior clerestory windows or transoms
Another clever architectural solution for dark interiors is using clerestory windows or transoms high on the wall to share light between rooms. If one room is bright and an adjacent one is dark, installing a horizontal window near the ceiling (above eye level) between them can channel light through.
For example, an internal kitchen that’s dark might borrow light from a sunny living room via a clerestory glass panel at the top of the dividing wall.
20. Consider a walk-on glass floor or rooflight
For rooms located in basements or under other living spaces, getting natural light can be extremely challenging. One innovative idea is to install a walk-on glass floor panel or interior rooflight.
This essentially means the floor of the room above becomes a glass window for the room below. For instance, if you have a dark cellar or a windowless lower-ground room, adding a section of toughened glass in the floor of the room above (which itself has windows or skylights) will allow light to come down.
Toughened Glass Systems manufactures walk-on glass rooflights to custom specifications, ensuring safety (laminated glass for strength).
