What Is the Estimated Cost for a Kitchen Extension In 2023?

A kitchen extension is a popular home renovation project that can add both value and functionality to your home. As of 2023, the cost of a kitchen extension can vary widely depending on several factors such as the size and complexity of the project, the materials used, and the location of your home. 

With proper planning and budgeting, it is possible to achieve a beautiful and functional kitchen extension at a cost that fits your budget. Whether you’re looking to create a modern and sleek space or a traditional and cozy gathering spot, a kitchen extension is a great investment in your home.

Our guide will provide you with the details you need on every one of the many distinct aspects that affect how much a kitchen expansion costs, including the construction project, professional fees, any required licenses, and more. We’ll also tell you how to stretch your dollars further.

Size of the Project

One of the most significant factors affecting the cost of a kitchen extension is the size of the project. A small, basic extension will be less expensive than a large, elaborate extension with high-end finishes and amenities. The complexity of the project can also affect the cost, as a complex design with multiple levels, skylights, and other features will cost more than a simple, straightforward design.

Materials

The materials used in the project will also play a role in determining the cost, with high-end materials like calacatta quartz countertops, custom cabinetry, and high-end appliances driving the cost up, while more affordable materials like laminate countertops and standard appliances will help to keep costs down.

Homeowners can expect to spend between £10,000 and £15,000 on materials alone for a basic kitchen extension.

Location

The location of the property will also play a role in the cost of a kitchen extension, as prices can vary greatly from region to region, and even from city to city. 

For example, the cost of labor and materials in a major metropolitan area like New York City will likely be higher than in a smaller, less populated area. On the other hand, in more rural areas with more land, the cost of a kitchen extension may be lower due to the lower cost of land and simpler construction requirements.

Additionally, the cost of living and the local economy will also impact the cost of the project, with prices being higher in areas with a high cost of living and a strong economy.

Professional Fees

An extended kitchen will cost between three and seven percent of the total construction budget for design expenses.

The price of the planning drawings is about £2,700.

Based on the size of the house, a measured survey of the current home will run between £800 and £2,000 in price.

The cost of construction drawings that are adequate for construction (and for obtaining building regulations approval) is normally the same as the cost of planning drawings, which is about £2,700.

The substructure, roof, any big span openings, and structural adjustments to the existing house all require the services of structural engineers, whose rates start at £800.

Planning Approval Cost

You might be able to extend without needing planning approval by making use of authorized development rights, which will also help you save time and money.

Even if you choose this path, it is still wise to purchase a certificate of legitimate development, which typically costs £103. This can help you prove that your kitchen addition did not need planning approval when it comes time to sell your home.

Kitchen Average Cost

While it’s difficult to provide a precise estimate for the cost of a kitchen extension, the following are some rough estimates based on average costs for common kitchen extension projects:

A small kitchen extension (10 to 15 square feet) with basic finishes and materials: $30,000 to $50,000

A mid-sized kitchen extension (20 to 25 square feet) with high-end finishes and materials: $75,000 to $100,000

A large kitchen extension (30 square feet or more) with custom features, high-end materials, and professional contracting services: $100,000 to $150,000 or more

It’s important to note that these are just rough estimates, and the actual cost of your kitchen extension could be higher or lower depending on the specific factors involved in your project. If you’re considering a kitchen extension, it’s best to work with a professional contractor to get a more accurate estimate of the cost, based on your specific needs and preferences.

Conclusion

The estimated cost of a kitchen extension can vary greatly depending on the aforementioned factors. By working with a professional contractor and considering all of the factors involved in the project, homeowners can get a more accurate estimate of the cost and make informed decisions about their kitchen extension.
