Single storey extensions are a great way to add space and value to your property. A single storey extension is often very cost effective and they're suitable for a wide variety of properties. Smaller single storey home extensions can be built without having to make an application for planning permission as they are protected by permitted development rights. Substantial single storey extensions will still need planning permission. Single storey home extensions can also often be located to either the side or back of a house. Single storey home extensions are often used to expand kitchen areas or even to add a downstairs study or utility room.

 

They are also often used to create a larger open plan area in the downstairs of the property that could be used as a kitchen diner or living area. Adding roof lighting 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 simpler than other varieties of extension, careful planning continues to be needed to make sure that the new space is useful and beautiful. Experienced architects and builders will be able to give you advice on the most suitable design for your home extension, taking into account the needs of the new space as well as the best way to complement the pre-existing building. Your single storey home extension could be designed to accentuate your pre-existing property and employ similar materials for its construction or be designed to contrast, presenting a striking effect by using different materials.

 

Aspects that effect Single Storey Extension Costs

There are a few elements to bear in mind when you are establishing your budget plan. The primary elements that affect the cost of a single storey extension are the size and the coating. However there are various other elements that it is worth remembering while you are making your strategies.

Very Expensive Groundworks Needed

If it is hard to dig the foundations and also lay the footing for your extension, after that this can raise the price of your extensions. This could be the instance if the ground is difficult to work with. Particles in the ground can also increase the costs.

  • Quality of Fixtures and Fitting
    After the size of the extension, the following greatest factor is the grade of the coating. Picking high-end options can bring about the last rate being greater than double what it would be when choosing the basic options.
  • Dimension of Extension
    When you are getting an extension on your house, the single most significant variable that will influence the price of your extension is the size of it. The bigger the extension is, the more you will certainly wind up paying. If the location inside the extension is easy, without internal wall surfaces, then this will certainly reduce the cost per m2 somewhat. However, despite this in mind. The bigger the area of your extension, the a lot more you pay.
  • Kind of Extension
    The type of extension you select will go a long way towards dictating just how big your extension will be. Side return extensions create the smallest added space so are often the cheapest alternative, while a wraparound cooking area extension will certainly create the most area and also have the most pricy fittings and fixtures.
  • Building Regulations
    In most cases, building policies don't add a great deal of cost to a building job. However, if you are building an extension onto an older house, there might be some unforeseen costs. This is particularly true if the home has actually not lately been updated. Building laws will apply to your whole house, not simply the extension. This can cause the need for electrics to be checked out or door replaced.

 

Kitchen Extensions:

Kitchen extensions mainly fall under the realms of single storey extensions, although all type of property extensions could be made use of to integrate extra room for a kitchen.

As an approximate guide, a single storey extension will cost from ₤ 1,000 - ₤ 2,000/ m2, with a standard develop at the reduced end of the scale and also an excellent build top quality at the greater end at a variety, with prices of ₤ 2,500/ m2 plus.

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 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.
