One of the most common questions that our team are asked is What is the cost of a house extension in Leeds?

House extensions add a great amount of value to your home and are often a significant investment so naturally we expect that any first enquiries will be related primarily to cost.

This short guide should give you an approximate idea as to the cost of a house extension in Leeds.

Factors that affect the cost

Providing exact costs for an average extension can be tricky as they come in such a variety of shapes and sizes; ranging from a single storey extension providing space for a playroom or larger kitchen, to a double storey extension giving extra living space and bedrooms.

In addition to the type of extension there are a number of factors that can affect the build budget for a house extension:

  • The material you choose for the build i.e. stone, brick, or rendered breeze block
  • How easy it is to get access to the site
  • Whether the extension is single story or double storey
  • The ground conditions at the site
  • The material for the windows of the extension i.e. UPVC, Aluminium or Timber
  • The type of roof your extension will have i.e. flat or pitched
  • The location of the build
  • Any fittings and furniture you would like inside i.e. new fitted kitchen
  • The type of foundations required

How much should I expect to pay?

As a rough guide for an average size, it costs approximately £1100+Vat per square metre for a single storey extension and £1500+Vat for a double storey - this includes basic electrical and plumbing work too.

This is a rough guide assuming a good standard and specification of build - For a free estimate that is more specific to your project all you need to do is give our friendly team a call.

You may also want to consider any non-build costs including:

  • Any kitchen and bathroom fittings or appliances that you need for the new extension to be able fulfil its purpose
  • Planning costs which can be around £1000 to £3000
  • Any flooring for the extension
  • The cost of any painting and decorating to finish the new rooms

Where do I go from here?

There are so many different choices available with a house extension, and therefore a lot of decisions to be made. All of these decisions can affect the costs considerably so it is sensible to sit down with your chosen builder and discuss the options available so that you make a choice that fits both your requirements and your budget.

Selecting the right local builder to work on your house extension is almost as important as the work itself. We would always recommend choosing a company that you feel have the necessary experience, that you can trust and that have a team that are willing to answer all of your questions.
