Thinking of adding a skylight kitchen extension to your home? Great idea! Installing a rooflight extension allows you to expand your kitchen so that you can enjoy the wonders of natural lighting when preparing meals, hosting guests, or enjoying family dinners.
Apart from more natural light, skylights also allow for better ventilation, while also enhancing the aesthetic appeal of your kitchen.
Looking to add your own skylight kitchen extension? In this article, we’ll cover everything you need to know — its benefits, cost, building regulations, and much more.
When choosing where to install your skylights, you must weigh what you want to create against the practicalities and functionality of your kitchen. For example, while positioning a skylight over the dining area paints a striking picture, it does limit you from hanging a pendant light, which could boost the overall ambience during dinner in darker months.
Other points to consider include:
When choosing a skylight, one of the first things to consider is its function. Kitchens are notoriously steamy, so ventilating skylights are a fantastic option, especially above the hob. You could choose to have your roof lights electrically hinged, which would make opening them that much easier and allow you to enjoy ventilation without the hassle.
Want a larger type of skylight? Then a pyramid or roof lantern might just be the style for you. They bring in more light and provide better views of the sky above. However, you won’t be able to open and close them. And if you’re struggling to squeeze another skylight into the back of your extension, there are also sun tube varieties on the market. They allow light to be tunnelled to spaces in your home where there just isn’t the roof space to accommodate a larger roof light variety.
Another factor worthy of consideration is its position. Although natural light has its fair share of benefits, you don’t want so much natural light flooding your space that it becomes uncomfortable. Correctly positioning your roof light will ensure that just the right amount of sunlight enters your room.
Other factors worthy of consideration include:
It’s crucial you invest in the right glazing for your skylights, as trying to cut costs using cheap glass will only cost you more in the long run. Proper glazing will retain heat in winter and protect your home from excessive heat during the summer.
When choosing between toughened glass and laminated glass, remember that, although toughened glass is quite common, laminated glass is safer (rooflights made from laminated glass are less likely to fall into the room if they break). Other glazing options to choose from include:
Low maintenance glazing: this treatment is ideal for windows in hard reach areas and therefore a fantastic compliment to skylights. The coating is applied to the external facing side of the glass and fills in any pores or divots on the surface, which creates a smooth, durable surface - easy to clean and needs little maintenance inbetween.
Solar control glazing: as the name suggests, this window treatment will help reduce the adverse affects of the sun from influencing your home. The special coating reduces the amount of heat entering your extension, as well as reduce glare. You can opt for different types of solar control glazing, such as reflective, tinted, or plain old neutral.
Acoustic glazing: isn’t a treatment but is a sandwich of two or more sheets of glass, which when bonded together with polyvinyl butyral (PVB) interlayers, creates a noise reducing affect. If you live near a busy road or in an urban area, acoustic glazing could be a fantastic investment to help keep noise pollution to a minimum.
Privacy glazing: traditionally, privacy glazing consisted of solely frosted glass. This can help prevent Peeping Toms, but isn’t the nicest glass to be staring at all day. However, now homeowners can opt for on and off privacy, with new glazing turning frosted on command.
To ensure energy efficiency, confirm that the manufacturers declare ‘whole product U-values’ not ‘centre pane’ U-values. Whole product U-values ensure thermal performance, which allows you to comply with Part L building regulations. This way, your home will be energy efficient, and you’ll save more on your bills.
There are several factors to consider when deciding whether to use flat or pitched skylights in your kitchen renovation.
On the whole, hinged or access hatches are traditionally seen on pitched roof extensions, as their shape limits your choice in glazing. Because pitched roof extensions tend to have higher ceilings, most homeowners also choose to opt for fixed additions, as you’re unlikely going to need to open and close them. However, if you do want that extra bit of ventilation, then investing in an electrical hinge might be a good idea. And for extra ease, you could also combine your skylights with low maintenance glazing.
Pitched rooflights can only be installed on flat roofs, and this include glass lanterns of pyramids. Flat skylights are more cost-effective and a great choice if you prioritise ventilation. In contrast, pitched skylights (roof lanterns) welcome more natural light and blend better with Edwardian, Georgian and Victorian houses - a nice way of tying in your flat roof extension with a period property asthetic.
In this flat roof kitchen extension in London, the homeowners combined fixed skylights and sliding doors for a slick, modern style.
Building regulations are a set of regulatory laws that are there to ensure that the appropriate safety standards are adhered to.
For your glass roof kitchen extension to be deemed safe, it must meet the required fire, safety, ventilation, and energy conservation requirements.
These requirements are numerous and easily confusing to any homeowner. For larger extension projects, you can commission a building regulations package so that your contractor has detailed technical drawings to work from on site.
When it comes to deciding on the size of your roof lights, it’s worth noting that there are several factors you’ll need to bare in mind. Not just from a design point of view, but also from a planning. Here are some questions to consider when it comes to your skylights…
If you want to build without the need for a full planning application, then you’ll want to utelise your permitted development rights. However, in order for your project to qualify, you’ll need to make sure your extension retains the existing characteristics of the existing build. This means, if you use too much glazing, it could be seen as too impactful on the facade and face scrutiny from the council. To avoid this, it’s worth working with either an architect or your local authority to see where the limit on glazing exists.
The larger the skylight the more glazing involved, and this will push your costs up. Where you need to keep an eye on the numbers, is whether or not structural glazing will be required. This type of glass tends to be used for larger features, such as glass ceilings or floating corners, and it is a beautiful addition to any home. However, structural glazing does come with a high price tag, so if you want to go big with your skylights, it might be worth mapping out the costs with a specialists beforehand.
The cost of a skylight kitchen expansion depends on its size, complexity, location, and materials used.
Installing glass roof panels alone could cost between £850 to £1,200, while the price of glazing could be anywhere from £400 to £3,000. Though, it should be noted, these estimates are susceptible to change.
Outside of adding skylights, here are a few more ideas on how you could improve the light in your kitchen extension.
If you have the money, why stop at just a simple skylight? Glass ceilings are a bold addition to any extension and fully maxmise on the natural light brought into your home. This is a popular option for homeowners extending their property out to the side or through a wraparound, as a long glass ceiling running the length of an open plan room can help light penetrate the entirety of the space.
For those using a rear extension, you can still maximize on light be adding to your project floor to ceiling glazing. This doesn’t have to be a purely decorative feature. Many people use sliding or bi-fold doors to get the same effect. A clever design trick to have your kitchen floor mirror that in your patio, so your eye sees your outside space as a continuation of the indoors - creating the illusion of a much bigger room!
This 2016 project used multiple skylights along the extended side of the kitchen, allowing them to get the same affect as a glass ceiling but without the larger price tag. Alongside this, they invested in floor to ceiling glazing for a max out amount of natural light.
Glazed doors don’t just have to stop at the back of the property. By making your internal doors glass too, you allow the light from your skylights to travel all the way through the property. This means you get the benefits of an open plan space, without having to loose the distinction between spaces.
A fantastic option for homeowners extending a pitched roof. What’s more, you can combine your glazed gables with glass doors for the ultimate floor to ceiling look, gaining the maximum amount of natural light into your home, while creating a beautiful facade.
Whether you’re on a budget or just want to maxmise every opportunity for extra light, using a bright colour scheme will make a difference to the look and feel of your home. White colour schemes will help make your space feel bigger, while bold accents of colour (yellow or blue) can help break this look up and stop it from feeling bland. Alternatively, you could go for the scandi look and mix bright whites with earthy wood textures.
Adding an extension to your home can increase the value of your home. However, its added value will depend on its size and finishing.
Still, if you're hoping to make a return on your investment, we recommend you find out the maximum amount a property can be sold for in your area before embarking on your project. You want to make sure that the value it adds outweighs the installation cost.

How to maximise light in an extension?
There are plenty of great ways to maximise the light in your home if you’re building an extension. One great option is to have skylights installed to flood your space with natural light. Other options include having bifold doors installed or designing extra windows into your project plan.
How do you position skylights in an extension?
How you position the skylights in your extension will depend on what you’re hoping to achieve by having them installed. If you want to illuminate a kitchen island with natural light, for example, you’ll want to place your skylight directly above it to make the most of the daylight. Alternatively, if you’re trying to improve the flow from indoors to outdoors, you could have your skylights installed in a line, or “path” from one to the other. This will maximise the light inside while also drawing your eye outside.
Should skylights face north or south?
North-facing skylights are a great option if you’re looking to introduce fairly constant daylight illumination into a space but don’t want to risk high temperatures in hotter months of the year. If you’re looking to boost light and heat to the maximum degree, a south facing skylight will be more suitable for your extension.
