What Affects the Cost of a Rear Kitchen Extension on a Terraced House?


Terraced houses can sometimes be a little bit cramped compared to semi-detached properties or standalone homes. Many of the terraces in our cities and towns were originally built as a way of housing workers who were moving away from agricultural houses during the industrial revolution. Terraces are a very important part of the heritage of the United Kingdom; however some older properties do not offer their owners much space. Because of the space issues, terraced house extensions are one of the most common types of extension in the country. These extensions are also common in other locations around the world.

A rear kitchen extension is a particularly good way to give your house more space and to create the kitchen that you have always dreamed of. In order to get terraced house extensions such as these you will have to be prepared to pay thousands of pounds, although it is possible to get an extension on a budget. But what affects the cost of a rear kitchen extension? In fact, there are a lot of different factors which might end up having an effect on the price that you are quoted. Some of these factors will be explored in the discussion below.


One of the most important determinants of the price of a kitchen extension is the size of extension which you require. In general, the larger the extension that you require, the more that you will have to pay for it. However, economies of scale generally mean that increases in price are not linear, so small size increase is unlikely to make a huge difference. Terraced house extensions are normally limited in size. If you are considering a house extension, you will also need to decide whether you want to make a single storey extension or whether it might be possible to build a multi-storey extension. If you require more than one storey, then you will have to be prepared to pay much more. This not only covers the extra costs of the visible building materials, but it also covers the cost of building stronger foundations on which to site the extension.


The place where you live can actually affect how much you will pay for a rear kitchen extension. It is unsurprising that building costs vary widely from country to country, but many people do not realise that building costs can actually differ depending on which area of the United Kingdom the house is in. In general, an extension is likely to cost more on a house in the south east of England than it would cost if the same extension were to be built on a house in the north of England or in Scotland. This trend can be seen across almost any type of building work, and not just extensions.



The architect or designer who helps you to create the plans for your extension will have a big impact on the price of the work. A more skilled designer with a larger portfolio of work is likely to cost more than a designer who is in the earliest stages of their career. If you want a high quality of work and innovative ideas, then you will have to be prepared to pay more for this.

Building Materials

The building materials which are used in your rear kitchen extension will have a huge impact on the final cost of the work. Basic stones, woods, concrete, and tiles are amongst the least expensive materials that you can choose for your project. If you wish to have a marble floor or granite worktops in your extension then this will help to push up the price of the job. If you are on a budget then you may want to start off by commission a project with standard materials and then add “must have” extra design features depending on the level of funds that you still have available to work with.
