Quick summary

Open plan kitchen extensions are popular for creating spacious, light-filled areas that connect your kitchen to dining or living spaces, often increasing home value. Costs typically start around a few thousand pounds per square metre, depending on size and design, with projects taking several weeks. They are ideal for socialising and family life, but exclude complex structural changes or high-end finishes.

Open plan kitchen extensions are some of the most popular types of renovation in the present day. We take a look into what exactly they are, what an open plan kitchen could add to your home and some examples directly from our portfolio so you can get some real-life inspiration for your project.

What is an open plan kitchen extension?

An open plan kitchen extension layout is when you have a clear, open space that connects your kitchen to both or either your dining and living space.

What are the advantages of an open plan kitchen extension?

Open plan kitchen extensions are spacious and flexible – they can open up your home and reduce the traffic that can come with more cramped spaces. An open plan kitchen can also create the illusion of even more space. What’s more, if you’re looking to increase the amount of natural light that reaches your kitchen, going open plan reduces the barriers that may have previously got in the way which will naturally brighten the area.

Open plan kitchen extensions are also a fantastic option for social family life, offering the opportunity to facilitate all household members in one place. Picture the parents cooking dinner or catching up on a few last emails while the kids crack on with their homework before everyone sits down to the table to enjoy a comforting plate of spaghetti. In the same way that open plan kitchens accommodate social time with families, they also make great spaces for those who love to host gatherings.
