Single storey extensions are a great way to add space and value to your home. A single storey extension can be very affordable and they are appropriate for numerous properties. Smaller sized single storey home extensions can be built without having to make an application for planning permission as they are protected by permitted development rights. Sizeable single storey extensions will still need planning permission. Single storey home extensions can also usually be located to either the side or rear of a property. Single storey home extensions can be used to extend kitchen areas or even to add a downstairs study or utility room.

 

Also, they are often used to make a larger open plan area in the downstairs of the house that might be used as a kitchen diner or living area. Adding roof lighting and bifold doors to your home extension will create a large airy space that provides a seamless transition into the garden. While single storey home extensions may appear simpler than other types of extension, careful planning is required to make sure that the new space is functional and beautiful. Competent architects and contractors can give you advice on the best design for your home extension, considering the requirements 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 match your current property and make use of similar materials for its construction or be designed to contrast, offering an impressive effect by using differing materials.

 

Aspects that effect Single Storey Extension Prices

There are a few variables to remember when you are setting your budget plan. The major aspects that affect the price of a single storey extension are the dimension as well as the coating. However there are other variables that it deserves remembering while you are making your plans.

Pricy Groundworks Needed

If it is hard to dig the foundations as well as lay the footing for your extension, then this can enhance the cost of your extensions. This could be the instance if the ground is difficult to work with. Particles in the ground can additionally raise the costs.

  • Grade of Fixtures and also Fitting
    After the dimension of the extension, the following largest variable is the quality of the surface. Choosing premium alternatives can lead to the final rate being greater than double what it would be when choosing the standard alternatives.
  • Size of Extension
    When you are getting an extension on your residence, the single greatest variable that will certainly affect 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 basic, without inner wall surfaces, after that this will reduce the cost per m2 somewhat. Nonetheless, despite this in mind. The bigger the area of your extension, the a lot more you pay.
  • Type of Extension
    The sort of extension you choose will certainly go a long way in the direction of determining how huge your extension will certainly be. Side return extensions produce the smallest additional space so are typically the cheapest choice, while a wraparound cooking area extension will create one of the most space as well as have one of the most over-priced fittings and also fixtures.
  • Building Regulations
    Most of the times, building regulations do not include a great deal of cost to a building task. Nevertheless, if you are developing an extension onto an older residence, there might be some unexpected prices. This is especially real if the house has not just recently been updated. Structure guidelines will relate to your entire house, not simply the extension. This can bring about the demand for electrics to be considered or door changed.

 

Kitchen Extensions:

Kitchen extensions mostly fall under the areas of single storey extensions, although all type of house extensions could be made use of to include extra room for a kitchen.

As an approximate overview, a single floor extension will cost from ₤ 1,000 - ₤ 2,000/ m2, with a standard construct at the reduced end of the range and also an excellent build quality at the greater end at a range, with prices of ₤ 2,500/ m2 plus.

If you’re planning to construct a kitchen diner extension, to help you set a budget and start planning you must first have a cost estimate that’ll complete the entire project. If not, there’s a probability that you may have to spend more than would have been necessary or probably break the bank to have the project done. In truth, there’s no single and short answer to this question as the cost of a kitchen diner is largely dependent of several variables. In this article, we’re going to give a good insight into kitchen diner extension cost so as to help you make informed decisions moving forward. Let’s take a look!

On the average, a kitchen diner extension will cost within the range of £25,000 to about £45,000, however if you happen to reside in London, you can expect the cost to be a lot more than that - closer to £60,000. And due to the fact that there happens to be a plethora of options out there, any decision to make be it on the size, tradesman, flooring, finishes or type of the kitchen diner extension, will have a considerable impact on the overall cost of the project. For instance, a basic kitchen diner extension cost can be within the range of £12,000 to about £15,000., while a high end kitchen diner extension can reach a whooping price between £80,000 to about £100,000.

The total cost of your kitchen diner project will rely heavily of the size as well as the quality of the finishes. For example, a kitchen diner extension that’s small and basic is likely to cost about £1,300 to £1,500 per square metre. However, if you’re going for higher quality finishes, you can expect to pay within the range of £1,900 to about £3,000 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.

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 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.
