The kitchen diner extension is one of the most popular renovation paths for UK homeowners. We explore what makes it such an appealing option, how it could benefit your home and how it could impact your everyday life. Let’s dive in…

Why should you opt for a kitchen diner extension?

Kitchen diner extensions typically open up your kitchen space by increasing the square footage and typically reorganising the layout to accommodate a dining area. The effect of this is to create a dedicated dining area in the kitchen, making it both a sociable and functional space.

Kitchen diner extensions can be a fantastic option for families with young children where it might feel like you’re constantly juggling food prep, work, the school run and getting important quality time together. They can also be great options for people who love to host friends and family from the comfort of their own home.

Does a kitchen diner extension add value to your home?

According to Homebuilding & Renovating, getting a kitchen extension could add up to 20% value to your property. This may be dependent on the size and scale of the extension, as well as the features included and the type of materials that may be used to complete the build.

How to prepare for a kitchen diner extension?

When it comes to undertaking an extension project, it’s really important to ensure that you’re ready to take on the disruption, cost and time that comes with it. Here are some important factors to consider:

Think of the type of extension you can get for your house

The type of kitchen diner extension you can get will be dependent on the shape and size of your existing property. For example, if you have a terraced house with no available space to the sides, you may opt for a rear kitchen extension to take advantage of the back garden space you have at your disposal.

Owners of Victorian terraced houses, on the other hand, often do have unused alleyway space to the side of the property that can be built in to extend the kitchen area and create a kitchen diner. If you’re fortunate enough to have a house with ample available space to both the side and rear of your property (for example, a detached or semi-detached house), a wraparound extension could be a great option for you.

Think about the type of layout you want your kitchen diner to have

Another important consideration when you’re planning your kitchen diner extension is what type of layout you’d like the eventual room to have. There are a number of different kitchen layout options to choose from – here is just a flavour of a few:

  • Island - This type of layout puts the kitchen island at the centre of the room. Kitchen island installation is one of the most popular renovations homeowners will make to their kitchens and for good reason. Introducing a kitchen island to your kitchen can create a dual use for the room – vital surface area for food preparation and a casual dining area. If you’re a particularly keen host and have room to play with, we’d recommend opting for a large kitchen island that you can fit multiple seats around.
  • U-shape kitchen - The U shaped kitchen layout is an enduringly popular choice for creating more space in a kitchen. Essentially, three counters form a U shape which offers homeowners plenty of space for both food preparation around the kitchen’s edge. It also provides plenty of empty floor space that can have a dining table moved into.
  • L shaped kitchen - Unlike a U shaped kitchen space, an L shaped kitchen layout combines two countertops. This layout leaves plenty of open space in the centre of the kitchen that offers homeowners the opportunity to include a dining table and, if you have enough room, a chillout area too.
  • Galley - Galley kitchens are sometimes referred to as corridor kitchens. They consist of two countertops facing one another and are often found in smaller houses or flats where space is scarce. Given their lack of space and arrangement, they don’t make particularly great candidates for kitchen diners. However, one option for this type of kitchen layout is to extend back into the garden to include a dining area towards the back of the house.
  • Single wall - This kitchen layout does what it says on the tin. The kitchen appliances and countertops are all arranged on one single side of the room. This is a great option for creating ample space for the rest of the room, particularly if you have limited space to work with.

Consider natural light

Having natural light in our homes is proven to have beneficial effects on both our mental and physical health. Given its importance, we’d recommend that you consider where your natural light comes into the room and ensure that your kitchen design welcomes it in. Your chosen designer or architect will be able to advise on the best way to invite natural light into your home for your home.

Get coordinated

Once you’ve decided on your kitchen layout and extension type, opt for a dining table and chairs that fit with the shape and aesthetic of your home. Make sure that your table and chairs aren’t too large or small for the room as it could throw off the balance. And, unless you’re introducing a colour pop with your furniture choices, we’d suggest sticking to one particular shade of wood for the room.

How much does a kitchen diner extension cost?

Kitchen extensions can cost anywhere between £40,000 and £200,000 depending on the size and scale of the extension, the type of materials used and how long it takes to build. There are plenty of other considerations to take into account as well: the condition of the existing house, whether you’re staying at home during the renovations and whether you decide to coincide your kitchen diner extension with retrofitting.

How long does it take to build a kitchen diner extension?

Home extensions of any kind are not an exact science and it can be tricky to estimate exactly how long it will take to be completed. This applies to kitchen diner extensions too, particularly as there are so many different options available and so much of the construction progress depends on the condition of your existing home. As a general rule of thumb, we’d suggest expecting at least 10 weeks of work for your kitchen diner extension but also being aware that it could take a lot longer.

Do you need planning permission for a kitchen diner extension?

Depending on the size and scale of your proposed kitchen diner extension plans, you may be able to proceed with your build under permitted development rights. However, if your plans exceed certain limitations, you may need to apply for planning permission. This could also be the case if your property falls within a conservation area or an area of outstanding natural beauty. Learn more and get tailored advice for your extension ideas from your local planning officer.

How do you extend a small kitchen?

There are plenty of kitchen extension options available – even if you have a small kitchen. Depending on the existing layout of your kitchen (as well as the space surrounding your home), you may be eligible for a side extension, a rear extension or a wraparound extension.

Will extending my kitchen add value?

Extending your kitchen to increase the amount of space available or accommodate a dining area is a great way to add value to your property. It could add up to 20% to the value of your house. That being said, each home and extension project is different so this figure isn’t a guarantee and the difference it could make to the value of your home could vary widely.
