Is it Worth Knocking Through for a Kitchen-Diner?
Creating an open-plan kitchen-diner is one of the most popular home improvements in the UK. Many homeowners are choosing to knock through walls to combine their kitchen and dining area into one large, social space. But is it worth it? In this blog, we’ll explore the benefits, costs, potential challenges, and the latest design trends to help you decide if a knock-through is the right choice for your home.
The Benefits of a Kitchen-Diner Knock-Through
- More Space & Better Flow
Removing a wall between the kitchen and dining room can create a more spacious, open plan feel, making your home feel larger and more inviting. - Brighter Living Area
Traditional kitchens can sometimes feel dark and enclosed. Knocking through allows natural light to flow freely, creating a brighter and more pleasant living space. - Better for Entertaining
A kitchen-diner makes it easier to cook and chat with guests at the same time, making it perfect for dinner parties and family gatherings. - Increased Property Value
Open-plan living is highly desirable for buyers. A well-executed kitchen-diner conversion can add value to your home and make it more appealing to potential buyers. - More Functional Living Space
A combined kitchen and dining area can create a more practical, multifunctional space that suits modern family life.
Current Trends for Kitchen-Diners
If you're considering knocking through, thekitchn.com has some of the latest trends to incorporate into your design. These include:
- Moody Hues & Cool Metals
Rich, deep colours like navy, plum, and burgundy, combined with sleek metals like chrome and polished nickel, are making a bold statement in modern kitchens. - Concealed Kitchens
Seamless cabinetry and integrated appliances create a sleek, minimalist look, making your kitchen feel more like part of the living space. - Natural Materials & Warm Woods
Sustainable materials like stone and warm wood finishes bring a timeless, cosy feel to open-plan kitchen-diners. - Multi-Zoned Layouts
Kitchens are now designed with dedicated areas for cooking, entertaining, working, and relaxing, ensuring a functional and organised space. - Bold Colours & Mixed Materials
Combining soft and bold colours like sage green, dusty pink, and rich browns with organic textures adds depth and warmth to the design. - Open Shelving & Display Areas
Stylish open shelving provides both storage and a way to showcase personal style, keeping the space practical yet decorative. - Interesting Lighting
Statement lighting fixtures made of coloured glass, thick metals, or natural materials serve as focal points in modern kitchen-diner spaces. - Retro Influences
Vintage elements such as patterned wallpaper and colourful area rugs are making a comeback, blending nostalgia with contemporary design. - Sculleries & Secondary Kitchens
More homeowners are incorporating secondary kitchen spaces or sculleries to keep the main kitchen clutter-free. - Wellness-Focused Design
Biophilic elements like indoor plants, natural light, and calming colour schemes are being used to create a healthier, more inviting kitchen environment.
Considerations Before Knocking Through
- Is the Wall Load Bearing?
If the wall is structural, you’ll need a steel beam (RSJ) to support the weight of the upper floors. A structural engineer’s assessment is essential before proceeding. - Building Regulations & Permissions
Most internal wall removals don’t need planning permission but must comply with Building Regulations. Your builder should notify your local authority or work with a building control inspector. - Budget & Costs
The cost of a knock-through varies depending on whether the wall is load-bearing, whether you need to relocate plumbing or electrics, and the level of finish you require. On average, expect to pay between £2,000 and £5,000 for a standard knock-through. - Disruption & Mess
Removing a wall is a major job that will cause dust and noise. Be prepared for some inconvenience while the work is being carried out. - Heating & Ventilation
Open-plan spaces can be harder to heat and may require additional heating solutions, such as underfloor heating or a more powerful radiator.

Planning a home extension in Surrey , a loft conversion , or even a new build? One of the biggest early considerations is whether you’ll need planning permission . For many homeowners, the process can seem confusing—but with the right knowledge and an experienced Surrey construction company by your side, it becomes much simpler. At Jigsaw Construction Surrey , we’ve supported countless homeowners through planning applications, helping them move smoothly from paperwork to building work. Here’s our step-by-step guide to navigating planning permission in Surrey. Step 1: Do You Need Planning Permission in Surrey? Not all building projects require formal approval. Some fall under Permitted Development Rights (PDR), which may allow you to extend or convert your home without submitting a full application. However, in Surrey, these rights can be restricted if your property is: Within a conservation area A listed building Situated in the Green Belt 👉 Before starting your project, check with your local Surrey council or ask our team at Jigsaw Construction Surrey for guidance. Step 2: Understand Local Planning Policies Each borough—Guildford, Elmbridge, Woking, Epsom & Ewell, and others—has its own Local Plan, which sets rules for building work. These policies cover: Building scale and height Design and materials Neighbour impact (privacy, light, outlook) Environmental impact Researching these guidelines early gives your project the best chance of success. Step 3: Create Detailed Plans A strong planning application depends on clear, accurate documents. Typically, you’ll need: Architectural drawings (site plans, elevations, floor layouts) A Design & Access Statement explaining how your design fits local policy Supporting reports (e.g., tree surveys, flood risk assessments) At Jigsaw Construction Surrey , we collaborate with skilled architects to make sure every application is thorough and professionally presented. Step 4: Submitting a Planning Application in Surrey Applications are submitted online via the Planning Portal or your local council’s website. Fees vary depending on the type of project. Once submitted, your application enters the consultation stage. Step 5: Neighbours & Community Consultation Neighbours and other stakeholders are invited to comment on your application. Common concerns include: Loss of light or privacy Parking and traffic impact Design compatibility with the local area Tip: Talking to your neighbours in advance can reduce objections and speed up the approval process. Step 6: The Planning Decision Most councils in Surrey aim to decide within: 8 weeks for smaller projects (such as home extensions) 13 weeks for larger developments If approved, you’ll receive a decision notice with any conditions. If refused, you can appeal—or make changes and reapply. Step 7: After Planning Permission – Building Regulations Even if planning permission is granted, you’ll still need to meet Building Regulations . These ensure that your project is structurally sound, energy-efficient, and safe.
