Single storey extensions are a great way to add space and value to your home. A single storey extension can be extremely affordable and they're suitable for a wide variety of houses. Smaller sized single storey home extensions can be built without having to apply for planning permission because they are covered under permitted development rights. Sizeable single storey extensions will still need planning permission. Single storey home extensions can also typically be positioned to either the side or rear of a home. Single storey home extensions are often used to expand kitchen areas or to put in a downstairs study or utility room.

 

Additionally, they are often used to create a larger open plan area in the downstairs of the property that may be used as a kitchen diner or living area. Adding roof lights and bifold doors to your home extension will generate a huge airy space that provides a seamless transition into the garden. While single storey home extensions may appear less complicated than other kinds of extension, careful planning continues to be necessary to ensure that the new space is useful and attractive. Qualified architects and builders will be able to give you advice on the most effective design for your home extension, considering the needs of the new space as well as the best way to complement the present building. Your single storey home extension could be made to accentuate your pre-existing property and use similar materials for its construction or be designed to contrast, supplying a striking effect by using different materials.

 

Variables that effect Single Storey Extension Costs

There are a few aspects to keep in mind when you are establishing your budget. The primary aspects that influence the cost of a single storey extension are the size and the surface. However there are other aspects that it deserves bearing in mind while you are making your strategies.

Pricy Groundworks Needed

If it is difficult to dig the structures and also lay the footing for your extension, then this can increase the price of your extensions. This might be the situation if the ground is difficult to deal with. Particles in the ground can also raise the costs.

  • Grade of Fixtures and also Fitting
    After the dimension of the extension, the next greatest aspect is the quality of the surface. Picking premium options can result in the final price being more than dual what it would certainly be when choosing the fundamental options.
  • Dimension of Extension
    When you are obtaining an extension on your residence, the single largest aspect that will impact the cost of your extension is the size of it. The bigger the extension is, the much more you will certainly wind up paying. If the area inside the extension is simple, with no inner wall surfaces, after that this will reduce the price per m2 slightly. However, despite this in mind. The larger the area of your extension, the a lot more you pay.
  • Type of Extension
    The sort of extension you select will go a long way towards dictating just how large your extension will be. Side return extensions create the smallest extra room so are commonly the most inexpensive choice, while a wraparound kitchen area extension will develop the most area and have one of the most high priced fittings and fixtures.
  • Building Regulations
    Most of the times, building policies don't include a lot of price to a structure project. However, if you are building an extension onto an older residence, there might be some unexpected costs. This is particularly real if the home has not recently been updated. Building regulations will relate to your whole home, not simply the extension. This can cause the demand for electrics to be taken a look at or door replaced.

 

Kitchen Extensions:

Kitchen extensions mostly come under the areas of ground floor extensions, although all sort of property extensions could be used to include additional room for a kitchen.

As an approximate overview, a single storey extension will cost from ₤ 1,000 - ₤ 2,000/ m2, with a fundamental build at the lower end of the range and an outstanding develop high quality at the greater end at a range, with prices of ₤ 2,500/ m2 plus.

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 single storey extension add value to your house?

Does A Single Storey Extension Add Value To Your House?

When you’re looking to construct a single storey extension or perhaps you’re just searching for means to increase the value of your property, this question always pops up. The short and simple answer to this question is a resounding yes, a single storey extension can go a long way to increase the value of your property. Just like any other home improvement, when done right, adding a little extra living space is one of the top things you can probably think of that’ll provide a cool increase in your property’s value. However, before you rush in you must also take note of some factors so you can be certain a single storey extension is the right option for you. These factors include the quality of the build, complexity of the build, cost of the build versus the value gain, ceiling price in the area, finance costs as well as the inconveniences and stress.

Generally, the average cost of a single storey extension can range from £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. So it’s important to know the value they’ll add to your house before deciding to make such an investment.

The value added to your property will depend largely on the quality and size of your single storey extension. The value is usually calculated by estate agents using the number of bedrooms, bathrooms as well as the floor area. Inside London, it’ll typically be priced at £5,000 to £10,000 per square metre, while outside London should be within the range of £900 to £2,000 per square metre.

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.
