Single storey extensions are a great way to add space and value to your home. A single storey extension is often very cost effective and they're appropriate for a multitude of homes. Smaller sized single storey home extensions can be built without needing to apply 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 generally be located to either the side or back of a property. Single storey home extensions are often used to extend 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 property that may be used as a kitchen diner or living area. Adding roof lighting and bifold doors to your home extension will create a huge airy space that provides a seamless transition into the garden. While single storey home extensions may appear simpler than other sorts of extension, careful planning is necessary to ensure that the new space is useful and attractive. Qualified architects and building contractors will be able to give you advice on the most effective design for your home extension, considering the specifications of the new space as well as the best way to complement the existing building. Your single storey home extension could be designed to complement your current property and make use of similar materials for its construction or be made to contrast, giving an impressive effect by using different materials.

Daventry is a market town in Northamptonshire. It is 76.4 miles north-northwest of London and 13.9 miles west of Rugby. Sitting between 135 and 160 metres above sea level, it is encircled by hillsides reaching heights of 225 metres. Daventry is located on the watershed of the River Leam, which travels to the west of England, and the River Nene, which travels east. Having said that, there is not a river in the town and the most significant bodies of water stem from two tanks that feed the canal that swings from Watford Gap into the West Midlands through a 1.9 kilometre long Braunston Tunnel. Daventry is historically a rural town with a modest population, having around 4000 residents in 1950. Expansion took place from 1955 when British Timken, the tapered roller bearing maker, founded a large factory in the town. Coupled with being designated as an 'overspill' to settle people and industry from Birmingham in 1966 as part of an understanding with Birmingham City Council, the town continued to grow. There are a number housing estates, featuring Drayton, Middlemore Farm, Long Farm, Ashby Fields, Royal Oak, Timken, Stefen Hill, The Grange, The Southbrook and the Headlands. Despite such development, it did not reach the target population of 36000 by 1981, and the population of the town was documented as 25026 in the 2011 Census. The modern-day property and commercial development surrounds the town's historic market centre. 74 landmarks and structures in Daventry's town centre are on the List of Buildings of Special Architectural or Historic Interest led by the Church of Holy Cross at Grade I, and buildings including Market Place and the Danetre Hospital Offices are Grade II listed. For all your house upgrades, ensure to make usage of respected contractors in Daventry to make certain of quality.

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).
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.
Builders are everywhere, but finding one for your project can be tricky and stressful, with both cost and reliability coming into question. This is even more worrisome when you’re fully aware that your house extension can only be as good as the builder. If you’re also facing the same challenge, then you’ve come to the right place. In this article, we’ll share with you some tips on how to choose a professional and reliable builder who’ll ensure you get immense value for every penny spent. Let’s take a look!
✓ Ask for recommendations. To find a tradesperson, not just a builder, personal recommendations is the best way to go. Building a house extension is a major undertaking which comes with a lot of costs, so if you’re going to do it the least you can do is ensure you do it right. Carry out your research, ask friends and family, neighbours and loved ones if the know of any reliable builder in the local area. If they’ve have one they’ve used, you can request for the cost, quality of the job done, the duration of the project and any other detail you feel you should know.
✓ Search Online. Use our search feature to look at the builders available or submit and enquiry and we will find you one. Our site holds details of numerous builders and building companies which you can go through their ratings to select the best.
✓ Select a reliable builder from trading association. Most reliable builders are usually a member of a recognized trading association or the other. Though this is not obligatory for builders, but it can be used as a dependable medium to find a good builder. We list what trade association the builders are a member of.
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.
