FAQs

how much is a ground floor extension?

Generally, extensions can be a very tricky undertaking - where it can be quite difficult to have a clear comprehension of the rules, regulations as well as costs. Therefore before you rush in to kick start your ground floor extension project, it’ll be wise to get a good grip on the cost. In this article, we’re going to give you a rough estimate of the cost of a ground floor extension. Let’s take a look!

Just like several other home improvement projects, the cost of constructing a ground floor extension is based on a number of things which includes the size, materials used, your location, the quality of the tradesmen or company hired and lots more. For instance, if you happen to reside in London, the cost of your ground floor extension is going to be a lot higher than the other regions.

The single cost of a ground floor extension should fall within the range of £1,500 per square metre to about £2,000 per square metre. However, if you happen to live in London or the South East, this price can reach up to £1,900 per square metre to about £2,400 per square metre. These prices are for good quality ground floor extensions only. Basic or low quality extensions would naturally cost less while superior quality extension will cost more.

Now looking at the size of the ground floor extension, if you’re looking for a size of about 5m x 5m, you can expect to pay a price within the range of £32,000 to about £36,000. And as usual, in London or the South East, this price can reach up to £50,000 or even more. And that’s just for constructing the extension. If the other relevant costs like the 10 percent to 15 percent professional fees for the architect, planning application (if needed), building regulations and more, the price goes up.

how much does a single storey house extension cost?

If you’re planning to build a single story house extension, this is one of the first questions that usually comes to mind to help you set a budget and start to make plans. But as simple as it seems, a single accurate answer can not be provided due to the fact that there are several variables that can play a key role in influencing the price of a single story house extension. These variables includes the size, location, design or specification as well as the build route. In this guide, we’ll provide you with a rough estimate that you can work with to put you on the right path.

The main determinant of the cost of a single storey extension is the size of the build, while the next most relevant factor is the quality of the finish you opt for. For a small extension, you can expect to spend a sum within the range of £14,000 to £17,000. Meanwhile for a larger single storey extension, if you opt for a large wrap around the extension with a great amount of glass to be incorporated in both the walls and roof, you can expect to pay a sum within the range of £80,000 to £120,000.

Overall, the average cost of a single story house extension is usually within the range of £34,000 to £37,000. For this price, you should get a standard sized rear or side extension which also includes the cost of a kitchen - it’s the most commonly use for a single story extension especially in the UK.

There are some additional costs you may also need to factor in to your extension budget. These includes surveys, architect fees, planning application fee (if needed), insurance and Party Wall Agreement (if needed).

does a kitchen extension add value to your house?

If you’re planning to add a kitchen extension to your property or perhaps you’re simply looking for ways to increase the value of your property, this is one of the common questions that usually pops up. A simple answer to this question is yes, a kitchen extension will add value to your house. With a kitchen being one of the most frequently used room in a house, adding an extra space to the commonly used room can only increase the value of the entire property. However, to determine the value added by such an extension, there’s a need to calculate the cost of setting one up first.

Kitchen extension costs are greatly influenced by a wide range of variables such as the size, type of the extension and specifications, your location, professional fees, materials used and more. Overall, the type of the extension you opt for will play the most significant role in the determination of your kitchen extension cost. Here, we’ll be looking at a single storey kitchen extension.

For a single storey kitchen extension, you can expect your home’s market value to increase within the range of 5 percent to about 10 percent. When trying to calculate the cost of kitchen extension, it’s crucial to take into account how much value it’ll add to your home so as to make sure that the amount expended will not outweigh the expected value to be added by the project.

For a more accurate idea, there’s the need to consult local estate agents. However, for a much needed guideline, single storey kitchen extensions are usually able to add about 5 to 10 percent to a home’s value, while double storey extension should be up to 20 percent. But as stated earlier, this will depend on several variables.

How to find a builder for a house extension?

Builders are everywhere, but finding one for your project can be tricky and stressful, with both cost and reliability coming into question. This is even more worrisome when you’re fully aware that your house extension can only be as good as the builder. If you’re also facing the same challenge, then you’ve come to the right place. In this article, we’ll share with you some tips on how to choose a professional and reliable builder who’ll ensure you get immense value for every penny spent. Let’s take a look!
