Pricy Groundworks Needed

If it is hard to dig the structures and also lay the footing for your extension, then this can increase the cost of your extensions. This could be the case if the ground is tough to work with. Debris in the ground can likewise raise the costs.

  • Caliber of Fixtures and Fitting
    After the size of the extension, the following largest element is the grade of the surface. Picking premium choices can lead to the last cost being more than double what it would be when picking the fundamental options.
  • Dimension of Extension
    When you are getting an extension on your house, the single most significant element that will affect the cost of your extension is the size of it. The larger the extension is, the much more you will certainly wind up paying. If the area inside the extension is easy, without any internal wall surfaces, then this will certainly decrease the cost per m2 somewhat. However, even with this in mind.

  • Sort of Extension
    The type of extension you select will certainly go a long way in the direction of dictating exactly how huge your extension will be. Side return extensions produce the smallest extra room so are typically the cheapest option, while a wraparound cooking area extension will certainly develop one of the most room and also have one of the most very expensive fittings and also components.
  • Building Regulations
    In many cases, constructing laws do not add a great deal of cost to a structure task. However, if you are building an extension onto an older residence, there may be some unforeseen prices. This is specifically true if the residence has not lately been updated. Building guidelines will apply to your whole house, not just the extension. This can lead to the requirement for electrics to be taken a look at or door changed.

FAQs

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 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).

how much does a kitchen extension cost?

Being the most used room in a house, it’s little surprise kitchen extension are usually one of the most popular requests in the UK. They do not only open up a frequently used space in your home, but also goes a long way to add value to your property. However, to know the value that’ll added you must first determine the cost of building such an extension before moving forward. Generally, a typical kitchen extension will cost within the range of £20,000 to about £50,000 plus VAT, based on the size of your project as well as your location.

In reality, a single accurate cost of a kitchen extension will vary depending on a lot of influencing factors, one of which is the type of the extension. Let’s take a look!

✓ Rear extension. You may want to consider this type, if you do not have sufficient space for a side return. This will extend your kitchen into your garden which implies that you’re going to give up some green space to make this a reality. The average price to have this done in London will be about £30,000 or more including VAT, and about £20,000 plus VAT or more in other areas.

✓ Side return extension. This, normally, isn’t a huge add to your property, but will create a lot of space for your kitchen while also be a lot reasonable in terms of cost. This type will extend your home into an alleyway at the side of your property if any is available there. On average, the cost of the side return extension should be about £50,000 plus VAT in London and a lot less in the other regions.

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.
