Single storey extensions are a great way to add space and value to your house. A single storey extension can be extremely cost effective and they're appropriate for a wide variety of houses. Smaller single storey home extensions can be built without the need to apply 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 typically be positioned to either the side or rear of your house. Single storey home extensions are often used to extend kitchen areas or to add a downstairs study or utility room.

 

Additionally, they are often used to make a larger open plan area in the downstairs of the property that could be used as a kitchen diner or living area. Adding roof lamps and bifold doors to your home extension will create a sizeable 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 is essential to make sure that the new space is practical and beautiful. Experienced architects and building contractors will be able to advise you on the best design for your home extension, considering the requirements of the new space as well as the best way to complement the existing building. Your single storey home extension could be made to match your present property and make use of similar materials for its construction or be designed to contrast, supplying an impressive effect by using different materials.

 

Elements that effect Single Storey Extension Costs

There are a couple of aspects to remember when you are setting your budget. The main variables that influence the cost of a single storey extension are the dimension and also the surface. But there are various other variables that it deserves remembering while you are making your strategies.

Costly Groundworks Needed

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

  • Quality of Fixtures and Fitting
    After the dimension of the extension, the next largest element is the caliber of the surface. Choosing high-end options can cause the last cost being greater than double what it would be when choosing the standard alternatives.
  • Dimension of Extension
    When you are getting an extension on your house, the single most significant factor that will certainly influence the cost of your extension is the size of it. The larger the extension is, the more you will certainly wind up paying. If the area inside the extension is basic, without interior walls, after that this will decrease the price per m2 slightly. However, despite having this in mind. The bigger the area of your extension, the much more you pay.
  • Kind of Extension
    The kind of extension you pick will go a long way towards determining just how big your extension will certainly be. Side return extensions develop the tiniest additional area so are usually the cheapest option, while a wraparound kitchen area extension will produce the most area as well as have the most over-priced fittings and components.
  • Building Regulations
    For the most part, constructing regulations do not include a great deal of cost to a building task. Nonetheless, if you are developing an extension onto an older residence, there may be some unforeseen costs. This is particularly true if the home has not lately been updated. Structure guidelines will relate to your whole home, not just the extension. This can bring about the demand for electrics to be looked at or door replaced.

 

Kitchen Extensions:

Kitchen extensions greatly fall into the areas 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 guide, a single storey extension will set you back from ₤ 1,000 - ₤ 2,000/ m2, with a standard construct at the reduced end of the range and also a superb build quality at the greater end at a variety, with costs of ₤ 2,500/ m2 plus.

FAQs

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 does a kitchen extension cost?

Being the most used room in a house, it’s little surprise kitchen extension are usually one of the most popular requests in the UK. They do not only open up a frequently used space in your home, but also goes a long way to add value to your property. However, to know the value that’ll added you must first determine the cost of building such an extension before moving forward. Generally, a typical kitchen extension will cost within the range of £20,000 to about £50,000 plus VAT, based on the size of your project as well as your location.

In reality, a single accurate cost of a kitchen extension will vary depending on a lot of influencing factors, one of which is the type of the extension. Let’s take a look!

✓ Rear extension. You may want to consider this type, if you do not have sufficient space for a side return. This will extend your kitchen into your garden which implies that you’re going to give up some green space to make this a reality. The average price to have this done in London will be about £30,000 or more including VAT, and about £20,000 plus VAT or more in other areas.

✓ Side return extension. This, normally, isn’t a huge add to your property, but will create a lot of space for your kitchen while also be a lot reasonable in terms of cost. This type will extend your home into an alleyway at the side of your property if any is available there. On average, the cost of the side return extension should be about £50,000 plus VAT in London and a lot less in the other regions.

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 to find a builder for a house extension?
