Single storey extensions are a great way to add space and value to your house. A single storey extension can be very cost effective and they're suited to a multitude of houses. Smaller sized single storey home extensions can be built without the need to apply for planning permission because they are covered under permitted development rights. Large single storey extensions will still need planning permission. Single storey home extensions can also generally be situated to either the side or back of a house. Single storey home extensions can be used to expand kitchens or even to put in a downstairs study or utility room.

 

Additionally, they are often used to make a larger open plan area in the downstairs of the house that may be used as a kitchen diner or living area. Adding roof lamps and bifold doors to your home extension will generate a big airy space that provides a seamless transition in to the garden. While single storey home extensions may appear simpler than other types of extension, careful planning is essential to ensure that the new space is practical and attractive. Professional architects and contractors will be able to give you advice on the most appropriate design for your home extension, taking into account the needs of the new space as well as the best way to complement the existing building. Your single storey home extension could be made to accentuate your existing property and make use of similar materials for its construction or be designed to contrast, presenting an impressive effect by using differing materials.

 

Factors that impact Single Storey Extension Costs

There are a few aspects to remember when you are establishing your spending plan. The primary aspects that influence the price of a single storey extension are the dimension and the finish. However there are other variables that it is worth remembering while you are making your strategies.

Very Expensive Groundworks Needed

If it is tough to dig the structures as well as lay the footing for your extension, then this can increase the price of your extensions. This could be the instance if the ground is difficult to collaborate with. Debris in the ground can also increase the costs.

  • Quality of Fixtures and Fitting
    After the dimension of the extension, the next most significant variable is the caliber of the surface. Selecting premium choices can lead to the last cost being greater than double what it would be when choosing the fundamental options.
  • Size of Extension
    When you are obtaining an extension on your residence, the single biggest variable that will influence the price of your extension is the size of it. The larger the extension is, the much more you will end up paying. If the location inside the extension is easy, without inner wall surfaces, after that this will certainly lower the cost per m2 somewhat. Nonetheless, despite this in mind. The bigger the location of your extension, the extra you pay.
  • Sort of Extension
    The kind of extension you choose will go a long way in the direction of dictating exactly how big your extension will be. Side return extensions create the tiniest additional area so are commonly the most inexpensive option, while a wraparound kitchen area extension will create the most space as well as have one of the most pricy fittings and also components.
  • Building Regulations
    For the most part, developing policies do not add a lot of cost to a structure project. However, if you are constructing an extension onto an older home, there might be some unforeseen costs. This is particularly real if the house has not recently been upgraded. Structure guidelines will put on your entire house, not simply the extension. This can bring about the requirement for electrics to be looked at or door changed.

 

Kitchen Extensions:

Kitchen extensions greatly fall into the realms of single floor extensions, although all sort of property extensions could be made use of to incorporate additional area for a kitchen.

As an approximate overview, a single storey extension will certainly cost from ₤ 1,000 - ₤ 2,000/ m2, with a fundamental build at the lower end of the scale as well as an outstanding construct high quality at the higher end at a variety, with costs of ₤ 2,500/ m2 plus.

FAQs

how much does a kitchen diner extension cost?

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.

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.

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.
