Sizeable single storey extensions will still need planning permission. Single storey home extensions can also typically be positioned to either the side or back of a property. Single storey home extensions can be used to expand kitchen areas or to add a downstairs study or utility room.

Adding roof lighting and bifold doors to your home extension will generate a big airy space that provides a seamless transition into the garden. While single storey home extensions may appear simpler than other kinds of extension, careful planning continues to be needed to make sure that the new space is functional and beautiful. Experienced architects and builders will be able to advise you on the most appropriate design for your home extension, taking into account the specifications of the new space as well as the best way to complement the pre-existing building.

Aspects that impact Single Storey Extension Prices

There are a couple of variables to bear in mind when you are establishing your budget. The primary aspects that impact the price of a single storey extension are the size and also the finish. However there are other elements that it is worth remembering while you are making your strategies.

Over-priced Groundworks Needed

If it is difficult to dig the foundations and lay the footing for your extension, then this can increase the cost of your extensions. This could be the case if the ground is difficult to collaborate with. Debris in the ground can also increase the prices.

  • Quality of Fixtures and Fitting
    After the size of the extension, the following most significant factor is the caliber of the surface. Choosing premium alternatives can bring about the final rate being more than dual what it would certainly be when choosing the standard alternatives.
  • Dimension of Extension
    When you are obtaining an extension on your home, the single greatest variable that will certainly influence the cost of your extension is the size of it. The larger the extension is, the much more you will wind up paying. If the area inside the extension is simple, without interior walls, after that this will decrease the price per m2 a little. Nevertheless, even with this in mind. The larger the location of your extension, the a lot more you pay.
  • Sort of Extension
    The sort of extension you select will go a long way in the direction of dictating how huge your extension will certainly be. Side return extensions develop the smallest extra room so are commonly the least expensive choice, while a wraparound kitchen area extension will certainly produce the most room and have one of the most pricy fittings as well as components.
  • Building Regulations
    In many cases, building guidelines do not include a great deal of cost to a structure job. Nevertheless, if you are developing an extension onto an older residence, there might be some unexpected costs. This is particularly real if the home has not recently been upgraded. Building regulations will apply to your whole residence, not simply the extension. This can bring about the demand for electrics to be checked out or door changed.

Balham

Balham is a district in south London within the London Borough of Wandsworth. The settlement appears inside the Domesday Book as Belgeham. Bal means ‘rounded enclosure’ and ham a homestead, village or river enclosure. The region has been settled since Saxon times, and Balham Hill and Balham High Road follow the line of the Roman road Stane Street to Chichester.

Balham encompasses the A24 north of Tooting Bec and also the roads coming off it. The southern part of Balham which is near Tooting Bec features a block of 1930s Art Deco flats called Du Cane Court. There's also the Heaver Estate which can be found in Tooting, which comprises substantial houses. It was built in the grounds of the old Bedford Hill House by local Victorian builder Alfred Heaver.

Balham is positioned between 4 south London commons, namely Clapham Common to the north, Wandsworth Common towards the west, Tooting Graveney Common towards the south and the connecting Tooting Bec towards the east.

During WW2, on 14th October 1940, Balham tube station was badly affected by air raids on London. Individuals sheltered inside the tube station during the raids, but a bomb fell in the High Road and through the roof of the Underground station, bursting a water and gas mains and killing around 64 people today. Ian McEwan describes the event as part of his novel ‘Atonement’, published in 2001.

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.

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.

do i need planning permission for a kitchen extension?

If you’re planning to construct a kitchen extension on your property, one of the first things that comes to mind is whether or not you’ll require a planning permission before you proceed. Generally, kitchen extensions are normally classified as permitted development which allows you to carry out your project without any interruptions from the law or your local authority. In other words, if your extension is meets up with the guidelines of the permitted development rights, you won’t have to apply for a planning permission. However if otherwise, you’ll have to apply for a planning permission to your local council and may require additional reports. And regardless of your position, you’ll always need building regulations approval before you can carry out any kitchen extension project. It may also be required that you’ll have to issue a part wall notice if you’re to build on or close to the boundary with a neighbour.

If you don’t want to go through the hassle and stress involved in applying for a planning permission with your local council, then you must ensure the following:

✓ Your kitchen extension must not be over half of the area of land around your main house.

✓ The kitchen extension must not be side elevation onto a highway or forward of the principal elevation.

✓ The extension must not be taller than the highest part of the roof.

✓ The height of your kitchen extension must not go beyond four metres.

✓ Kitchen extension that’s more than one storey must not go exceed the rear wall of the main house by more than three metres.

✓ Two storey kitchen extensions must not be closer to rear boundary by anything less than seven metres.

✓ The kitchen extension must not include balconies, verandas or any raised platforms.

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).
