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 multitude of properties. Smaller single storey home extensions can be built without having to apply for planning permission as they are protected by permitted development rights. Large single storey extensions will still need planning permission. Single storey home extensions can also frequently be situated to either the side or rear of your house. Single storey home extensions are often used to expand kitchens 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 home that might be used as a kitchen diner or living area. Adding roof lamps and bifold doors to your home extension will generate a sizeable airy space that creates a seamless transition in to the garden. While single storey home extensions may appear simpler than other kinds of extension, careful planning is still essential to ensure that the new space is practical and beautiful. Certified architects and builders will be able to give you advice on the most suitable design for your home extension, taking into account the specifications 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 existing property and employ similar materials for its construction or be made to contrast, presenting an impressive effect by using differing materials.

 

Factors that effect Single Storey Extension Prices

There are a couple of variables to keep in mind when you are establishing your budget plan. The main variables that affect the cost of a single storey extension are the dimension as well as the surface. Yet there are other aspects that it deserves bearing in mind while you are making your plans.

Expensive Groundworks Needed

If it is difficult to dig the foundations as well as lay the ground for your extension, then this can boost the price of your extensions. This may be the situation if the ground is difficult to work with. Particles in the ground can also increase the prices.

  • Caliber of Fixtures and also Fitting
    After the dimension of the extension, the following biggest variable is the quality of the surface. Choosing premium choices can result in the last cost being more than double what it would certainly be when picking the standard choices.
  • Size of Extension
    When you are obtaining an extension on your home, the single biggest factor that will certainly impact the cost of your extension is the size of it. The bigger the extension is, the extra you will certainly wind up paying. If the location inside the extension is basic, without interior wall surfaces, after that this will certainly reduce the cost per m2 a little. Nonetheless, despite having this in mind. The bigger the location of your extension, the much more you pay.
  • Kind of Extension
    The kind of extension you select will go a long way in the direction of dictating how big your extension will be. Side return extensions produce the smallest added space so are frequently the least expensive choice, while a wraparound cooking area extension will certainly create the most room as well as have one of the most high priced fittings and fixtures.
  • Building Regulations
    Most of the times, building policies don't include a lot of cost to a building project. However, if you are building an extension onto an older home, there might be some unanticipated prices. This is specifically true if the residence has actually not just recently been upgraded. Building regulations will apply to your entire residence, not simply the extension. This can cause the need for electrics to be considered or door changed.

 

Kitchen Extensions:

FAQs

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.

Carry out your research, ask friends and family, neighbours and loved ones if the know of any reliable builder in the local area.

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.
