How to Maximise Light when Building an Extension or Renovation

Gary Newell • 1 October 2023

Natural light is often lacking in our homes. At Jigsaw Construction, Surrey, we know how important natural light is for our mental health and wellbeing, so, this is something we look to address when carrying out renovation or extensions for our clients. It’s the perfect opportunity to look at ways to maximise natural light, which is not only aesthetically pleasing, but also energy efficient. Here we have some ideas and methods to do this:


Orientation and Design

By tracking how the sun moves around your home, we can properly orient the extension or renovation to make the most of natural light throughout the day. South-facing windows typically receive the most sunlight in the UK, but we can also consider open floor plans and design layouts that allow light to penetrate deep into the building. And plans can incorporate large windows, sliding glass doors, or folding doors to bring in as much natural light as possible.


Rooflights and Skylights

Rooflights or skylights added to the roof are excellent for introducing light into spaces that are otherwise hard to illuminate. Skylights can easily and quickly be installed in both flat and pitched roofs, and this does not usually require planning permission. They allow light to flood into the room throughout the day. Modern rooflight designs often come with glazing options that control heat gain, UV radiation, and glare.


Window Selection

Where budget allows, opt for high-quality, energy-efficient windows with low-emissivity (Low-E) glass to minimise heat loss and choose windows with a high solar heat gain coefficient (SHGC) to maximise the amount of solar energy entering the building.


Glass block windows are perfect for adding privacy without sacrificing natural lighting levels. Glass blocks offer complete privacy while still letting in plenty of sunshine during daytime hours. Plus, they’re available in various sizes and shapes giving you plenty of design options when selecting.


Window Placement

Place windows strategically to capture the most sunlight. Consider the angle of the sun throughout the day and the seasons. Use taller windows or windows placed higher up on walls to draw light deeper into the room. Casement windows have wide frames that open outward allowing for maximum air circulation and an unimpeded view of outside. Casements can also be combined with transom or fixed-pane windows above them to let in even more light while still providing ventilation.


Glazing Technology

Utilise advanced glazing technologies such as double or triple glazing to improve insulation which helps save on your heating bill whilst still allowing ample light. Use low-iron glass to increase the clarity and brightness of natural light.


Light Tubes or Solar Tubes

Install light tubes (also known as solar tubes or sun tunnels) to bring natural light into areas with limited access to external walls or windows. These are particularly effective for hallways, bathrooms, or other enclosed spaces.


Interior Design and Colours

Choose light-coloured interior finishes, such as paint, flooring, and furniture, to reflect and distribute natural light effectively. Avoid heavy window dressings that block or obstruct light when not needed. Hard floors with a polished finish, e.g., wood or stone, bounce light around the room.


Reflective Surfaces

Use mirrors or reflective materials strategically to bounce and amplify natural light throughout the room. Mirrors are a great way of reflecting natural light. As well as using wall-mounted mirrors, which create a great focal point, you can also consider mirrored furniture or ornaments.


Outdoor Spaces

Design outdoor spaces like patios or decks that connect seamlessly with indoor living areas. This can create a feeling of openness and allow more natural light to filter indoors.


Lighting Control

Install smart lighting systems with dimmers and sensors to adjust artificial lighting based on natural light levels, reducing energy consumption.


Landscaping

Trim or remove trees or bushes that may block natural light from entering the building.


Whatever strategy you choose will depend on the design of your extension or renovation, the location of your property, and your budget.
