A kitchen extension is a popular home renovation project that can enhance your property’s functionality, aesthetics, and value. Whether you want to create a more extensive cooking and dining space, add more natural light, or improve the flow of your home, a kitchen extension can provide the solution. However, one of the most common questions homeowners ask is, “How much for a kitchen extension?” The answer to this question depends on several factors, such as the size, complexity, and materials used for your project. In this article, we’ll provide you with a comprehensive guide to estimating the costs of a kitchen extension, so you can plan your budget accordingly.
How Much for Kitchen Extension: Factors that Affect the Cost
Size and Complexity of the Kitchen Extension
The size and complexity of your kitchen extension will have the most significant impact on its cost. Generally, the larger the extension, the higher the price. However, other factors can affect the complexity of the project, such as:
- The type of extension: A single-storey extension is typically less expensive than a double-storey or wrap-around extension.
- The design and layout: The cost will increase if you want a bespoke design or require structural changes, such as removing load-bearing walls.
- The level of finish: If you want high-end finishes, such as bespoke cabinetry, luxury appliances, or premium materials, the cost will be higher.
Materials Used for the Kitchen Extension
The materials used for your kitchen extension will also affect the cost. Here are some of the common materials used for kitchen extensions and their approximate costs per square metre:
- Brick and blockwork: £1,000 – £1,500
- Timber frame: £1,200 – £1,800
- Structural insulated panels (SIPs): £1,200 – £1,800
- Insulated concrete formwork (ICF): £1,300 – £1,900
- Glass and steel: £1,500 – £2,000
In addition to the structural materials, you’ll also need to consider the cost of other elements, such as:
- Roofing: Flat roofs are typically less expensive than pitched roofs.
- Glazing: The type and size of glazing will affect the cost, with larger and more complex designs costing more.
- Doors: Bi-fold or sliding doors will be more expensive than standard doors.
- Flooring: The cost will depend on the type and quality of the flooring you choose.
- Lighting and electrical: The cost will depend on the number and type of light fittings, sockets, and switches.
How to Estimate the Cost of a Kitchen Extension
Step 1: Define Your Requirements
The first step in estimating the cost of a kitchen extension is to define your requirements. Consider the following:
- What is the purpose of the extension? Do you want a larger kitchen, a dining area, a family room, or all of the above?
- How much space do you need? Measure the size you want to extend and consider the layout.
- What are your design preferences? Do you have a specific style or materials in mind?
- What is your budget? Be realistic about how much you can afford and what you’re willing to spend.
Step 2: Research Average Costs
Once you’ve defined your requirements, you can research the average costs for a kitchen extension. Use the information in the previous section to estimate the cost of each project element. Remember that these are just estimates, and actual prices may vary depending on your location, the complexity of your project, and the level of finish you choose.
Step 3: Get Quotes from Builders
Once you have a rough estimate of the cost of your kitchen extension, it’s time to get quotes from builders. Ask for recommendations from friends, family, or your architect. You can also use online services to find local builders and request quotes. When comparing quotes, ensure they include everything you need, such as materials, labour, and VAT.
Step 4: Consider Additional Costs
In addition to the cost of the construction, you’ll also need to consider additional costs, such as:
- Planning permission: If your project requires planning permission, you must pay for this separately. The cost will depend on your local authority and the complexity of your project.
- Building regulations: You must comply with building regulations, which may involve additional costs, such as inspections and certifications.
- Professional fees: You may need to hire an architect, engineer, or project manager, which will add to your costs.
- Contingency budget: It’s always a good idea to set aside a contingency budget of around 10-20% to cover unexpected expenses or changes to your project.
A kitchen extension can be a significant investment, but it can also transform your home and improve your quality of life. By understanding the factors that affect the cost and estimating your budget accurately, you can confidently plan your project and avoid unexpected surprises. Remember to research the average costs, get quotes from builders, and consider additional costs, such as planning permission and professional fees. You can create the kitchen of your dreams with careful planning and a realistic budget. So, how much for a kitchen extension? With the information in this guide by kitcheny, you’re well on your way to finding out!
How long does a kitchen extension take to build?
The duration of your kitchen extension will depend on several factors, such as size, complexity, and materials used. On average, a single-storey kitchen extension can take around 12-16 weeks to build, while a double-storey extension can take up to 6 months.
Do I need planning permission for a kitchen extension?
In most cases, you’ll need planning permission for a kitchen extension unless it falls under permitted development rights. Check with your local authority to find out the requirements for your area.
Can I save money by doing the work myself?
While it’s possible to save money by doing some of the work yourself, such as painting or tiling, it’s not recommended for structural or complex work. Hiring a professional builder will ensure your project is completed safely and to a high standard.
