How much does a kitchen extension cost?

We asked our UK wide community of architects and architectural designers on Design for Me for their experience of kitchen extension costs. Here’s the summary of our findings. These figures have been updated for 2021. It was noted by many that they had noticed a rise in material and labour prices in the last year.

Obviously, there are many factors at play and we’d recommend always getting quotes specific to your house, location, brief and site constraints. For more specific advice, you can post your project here to get advice from kitchen extension architects near you (and it’s completely free).

 

For most areas in the UK the starting cost of a typical 10m2 kitchen extension is £34,000

Based on responses from the architects and architectural designers on Design for Me.

 

Construction cost (Inc. VAT)

= from £30,000

This is starting figure and represents the best case scenario in terms of the site conditions, the simplest design and most modest specification. The cost will also depend on the choice of contractor where quality, finish and reliability can vary considerably!

 

Architect’s fees

For the smallest projects, the percentage of architect’s fees would typically be around 10-15%

= £3,000 – £4,500

 

+ Other consultants, services and fees

= from £1,000 – £3,000+

Not including costs associated with party wall award(s)

 

= Total of £34,000+

Managing or reducing your project costs

1. It pays to get professional advice from a good architect. They can help you realise the main ambitions for your extension, whilst helping control your costs. They will work with you to make sure you get the most out of your budget by recommending where your budget is best spent, and where costs would be unnecessary or could be minimised.

2. Make sure you get 3-5 quotes from recommended builders (your architect can help compile a tender list for you) to get a firm idea of the costs before starting work.

Your architect can also help you with your building contract, to prevent any nasty surprises down the line. They can also inspect the builder’s work to ensure it’s being carried out in accordance with the agreed design and specifications.

3. Shop around. Designers and contractors are sometimes able to to access trade discounts.
