Our Services
Derby House Extensions understand when your house is just not sufficient enough in size anymore for your needs. It could be more beneficial to create further space with a house extension as opposed to moving home, as this almost always comes with much greater financial commitments. If your Derby home requires that additional space for extending your dining room, living room, kitchen area, garage conversion into a home office, home gym, or man cave, maybe you could add that new extra bedroom upstairs that you have always wanted with our two storey house extension. We have all the skilled tradesmen and planning experts available who together with their years of combined knowledge and experience they can turn any home conversions into a reality.
Our main objective is to provide the best bespoke quality home extension services for each and everyone of our clients as we strive for perfection and repeat business, as this is our main aim, to give customers exactly what they want.

We also have access to a panel of professional Architects when required.

Rear Extension
A rear extension can really reshape your home by creating more room at the rear of the house. Whether the current property that you live in is detached, semi-detached, a period house or ground floor flat, a rear extension can offer the benefit of more space and open it right up into your garden area. Most people choose this type of extension as it is the most likely space available to them, and most likely comes under permitted developments. Think of how you would utilise this new living area — a more spacious lounge, kitchen diner, utility room, extra bedroom or office and study, so many permutations and ideas.

Side Return Extension
If your property has a spare strip of land or alleyway present that runs adjacent to your property, all the way through to your back garden, then it is a good possibility that you are one of the lucky people that could benefit from a side return extension to extend and enlarge your main residence. These dormant and wasted pieces of land are a usual part of a period, Victorian, Edwardian or around those eras property. Some customers will also include a rear extension within the conversion process which when combined with the side return is known as a wrap-around extension.

Wrap-Around Extension
Wrap-around types of home extensions incorporate a ground floor, L-shape extension building which reaches down through the side and around the back of your property. This can really maximise your available external space on the side of your house and by building out beyond the rear garden. The wrap-around extension can put together an impressively large amount of new habitable space, which can add up to a luxurious transformation to your existing property, add some recession-proof value and improve your all-round living experience.

Single Storey Extension
When you weigh up all the costs involved with upscaling to a larger property and all the upheaval that is involved, it is very understandable that many people are choosing to stay in their existing homes and extend their existing property, most often saving time, money and stress of the whole ordeal. A single storey extension could be your answer in solving this issue as they can provide some more comfortable liveable space for you and your family. These new spacious open-plan living areas can benefit your life by connecting you with the garden and outside spaces.

Double Storey Extension
A double-storey extension would be your best investment to increase the living space over two floors of your house. Spread over the ground and second-floor levels, these types of extensions can maximise the space added to your home environment and can produce double the amount of extra volume than other types of home extensions like rear, side return and wrap-around extensions. This can allow large families a much larger living space to maybe add those extra bedrooms or a large family bathroom extension.

Kitchen Extension
Kitchen extension is a popular choice, and why not, as they can add some significant value to an existing property as well as the practicality they bring by producing that extra space for you to enjoy — the kitchen really is the centre of any good home. We are experts in the construction of all types of kitchen extensions and build them to an exceptionally high level and quality. We can open up any small kitchen into a modern natural light-filled, functional and spacious kitchen that you will be happy to spend time in.

Basement Conversion
Basement conversions offer a fantastic solution to create that extra living space in built-up residential areas where limited external outdoor space can pose a problem for the construction of a home extension. A basement, which is naturally closer to your main living area and garden space than a loft extension, is a great way to produce more practical living space for your family. There are many different things you could convert your basement into, such as an extra living room, a guest bedroom, a luxury bathroom, or even move your kitchen underground.

Garage Conversion
A garage conversion can be a practical and cost-effective solution to create that extra space you may be needing for your home, without altering the actual structure or footprint of your house. Whether you are looking to accommodate your ever growing family, a kitchen extension, home office, study room, kids playroom or fitness home gym, then a garage conversion can certainly meet the needs of a modern family. We are specialists at converting garages seamlessly into the existing structure of your main property, which will look like it's always been there.

Loft Conversion
The main reasons for doing a loft conversion are: to add space to a home, to use the loft as living accommodation, or to use it for extra storage space. In most cases the head height is not a problem, but it is best to check this before you start the conversion process — it needs to be a minimum of 2.2 metres from the highest part of the rafters to the floor joists, but do not worry if not, as there are other methods available to create the desired height. You could have an extra bedroom with an ensuite, a playroom for the children, so many options to make your home larger without the need to move home.

Frequently Asked Questions
What size extension can I build?
It all depends on what type of extension you are thinking about having built. For example, your average rear extension, you can build up to four metres on a detached residence and three metres for all other kinds of houses without needing planning permission from any authorities or approval, as they may come under permitted development. As always there are stipulations and guidelines and it is worth checking beforehand with your local planning department. Building regulations will always apply. As for side return and wrap-around extensions, they must be single storey and no higher than four metres and not exceed more than half of the area of the original land around the house.
Can I extend my house without permission?
Rear extensions tend to be the easiest, with only a little red-tape involved. In most cases you can build up to four metres on detached residences and three metres for all other kinds of houses without needing permission from any authorities or approval, as they may come under permitted development. As always there are stipulations and guidelines and it is worth checking beforehand with your local planning department. Building regulations will always apply.
How much does an extension cost?
There are so many variables to consider, such as the size, the quality of materials you choose inside and out, and what you are going to build the extension for as your end goal. Fixtures, fittings and accessories can really affect the price — it all depends on your personal tastes and how high-end you would like to go. We get asked all the time, what is the cheapest way to extend my house? Call us and we can discuss your options.
Do I need an architect for an extension?
If your extension project is a very simple, straightforward design, and you have found out that you do not require any planning permission, you might be asking yourself whether you really need the expense of an architect. The short answer is no, you do not have to. If you do require an architect then we can fully recommend a panel of professional local architects in Derby that we trust with this kind of work.
Can you put an extension on the front of your house?
Under the set out permitted development rules and regulations there are clearly defined guidelines for side return extensions, rear extensions and wrap-around extensions. Front extensions on the other hand are normally NOT allowed, except where the property does not have frontage onto a highway or is a substantial distance away from the highway.
Does extending your house add value?
When considering adding value to your home with any particular house extension, it is important to make sure the extension matches the architectural style of your existing house. Most property conversions and additions will add value, if not straight away then certainly over a period of time. A quality built house extension could add anything up to 23% to the overall value of a property — nationwide research found that an additional bathroom extension could add around 6% to the value of a home, an extra double bedroom about 12% value, and a ground floor extension creating a double bedroom with an en-suite bathroom could increase the value of your home by up to approximately 23%. These figures are a guide and subject to change.
