- Home Extensions-


Extending is a popular way to add space without having to move. We explain everything you need to know from planning permission to costs, design work and much more.

It is said that for every person who self builds there are 15 that add extensions to their homes. The reasons for all this are easy to see. It often makes more economic sense to stay put and avoid the need to find a plot. It means we can stay in the same neighbourhood if we like it and that children can remain at the same school.

Why extend my home?

An overwhelming advantage of extending and not moving is the often-missed cost of stamp duty. It does not take a genius to work out that by the time you have calculated the agents fees for selling your house and the stamp duty you will pay on the one you are thinking of purchasing, you might aswell find you could build yourself a decent extension for the same cost.

Considerations before extending

The trick is to extend and come out well in the investment stakes, meaning you have put a lot of thought into even the smallest extension. For example, if you merely wish to extend the kitchen at the rear of your 1930s semi, should it be single storey or two storey? If it is the latter, what will go above it?

There are also practical issues to consider that are not directly concerned with the construction process. Access is a good example. If you add to your accommodation, will it mean more cars will be parked on the drive?

If you have no drive then the lack of off-street parking might be a reason for the refusal of planning permission.

Similarly, if your house is in a terrace do you have rear access for the unloading of building materials or if not, will you have to bring everything from beams to blocks, girders to guttering through the house?

Other important aspects to consider before you get to the stage of getting your plans drawn are matters like:

  • Soil conditions on the site
  • Services
  • Surrounding trees
  • Any history of flooding
  • Rights of way

- How much does it cost? -

There are many variables that will affect the cost of your extension such as soil type (which impacts foundations); whether you are building a single storey or two storey extension; what the extension will be used for, and how much glazing you are planning to specify.

Depending where you are in the UK, for a straightforward extension you should allow around £1,400-2,200/m2. Remember that the standard of specification you choose will have an enormous influence on the build cost.

Remember: Balance the amount you are willing to spend on your extension with the estimated value it will add to the home.
