How much does an extension cost in 2022?

Adding an extension to your home is a great way of saving money because it is cheaper than moving to a bigger home. Whether you want to increase the size of a current room, add a new room, or even an extra floor and extension is a great way to increase your living space.  

Material prices –  

It would be more expensive to build in 2022 because the prices for building materials across the UK have skyrocketed over the last year. This is due to the increase in supply and demand as a result of lockdowns and Brexit. Because there is a material shortage the prices have fluctuated massively.  

One thing you should consider and be okay with when looking for work to be done:  

  • Longer waiting times  
  • Quotes changing (prices can change quickly) 
  • Higher quotes 

How much does an extension cost?  

The cost of an extension varies majorly depending on the size, how you use it, and what features you would like. The less complex and smaller extension will be the most affordable. 

For a single-storey shell, the average price per square meter is:  

  • On a budget – £1,000 to £1,600.  
  • Mid-range – £1,700 to £2,000.  
  • Luxury – £2,200 to £4,000. 

Meaning on average a 30 square metre single storey extension built on a budget would cost between £30,000 to £48,000 in 2022. Excluding the fitting costs.  

Location of the home –  

The location of the home will affect the price of your build. Contractors in highly popular areas will often charge more, for example, London and the Southeast of the UK. 

How long does it take to build an extension?  

The longevity of the build all depends on the size of the build, the planning permission and gathering materials. Many contractors like to say the project will take around 3-6 months to be built. However, delays are very common, and you should be prepared for them to take slightly longer.   

Will an extension add value to the property?  

It’s almost definite that adding an extension would add value to your property. The average of a single-storey extension adds between 5 – 8 % value.

5 – Deck  

Decks are open outdoor porches or platforms without a roof. They are typically made out of wood or some simulation wood material.

Everything you should know before building a Flat roof

Flat roof extensions can provide a simple, cost-effective solution that ticks all of the right boxes. Especially for smaller extensions.  

What is a flat roof? 

A flat roof is a roof that is completely or almost level. However, whilst they are described as flat almost all flat roofs are laid to slope so that rainwater can run off to the lower side. The slope of the roof is properly known as its pitch. 

Where flat roofs originally from –  

Flat roofs are an ancient form mostly used in desert climates. Flat roofs exist all over the world, and each area has its own tradition or preference for the materials used. For hotter climates, where there is less rainfall many flat roofs are simply built out of masonry or concrete. This is because it is good at keeping the heat out, it is cheap and easy to build. Flat roofs are characteristic of the Egyptian, Persia, and Arabian styles of architecture.   

The main thing flat roofs are used for is extensions. They are exceedingly popular with those looking to create a cool, modern home. Flat roofs help to free up internal space and are often cheaper than a pitched roof. It is also easier to incorporate a green roof onto the structure if you want to go for an eco-friendly version.  

Pros and cons of flat roofs –  

Pros  

  • Installation & Maintenance – flat roofs are fairly easy to install. The maintenance is also easy because there is no fear of sliding off the roof when it comes to fixing it or cleaning the gutters.  
  • Price – the flat roof is generally a less expensive option. A flat roof requires less materials for the construction, and the materials are cheaper than tiles. They also take less tome to install.  
  • Internal space is not imposed on – the lack of pitch means that you don’t have to extend your property upwards, and maybe block some views. You can also put things on top of the roof and create a roof top garden  

Cons  

  • Temperature change – flat roofs absorb heat easier than flat roofs, because they are constantly absorbed by the sun. In the summer this can make your house very hot, however, in the winter it does the opposite and makes your house cold.  
  • Roof repairs – they are usually more expensive than a traditional pitched roof.  
  • Drainage – flat roof drainage is not as effective as pitched roofs and flooding can become an issue.

The informative basics to a Chalet/ dormer Bungalow

What is a Chalet bungalow?  

A chalet bungalow is a type of bungalow house that has a small living space on the second floor or loft. A bungalow is generally considered a one-storey structure that is detached from other structures. The chalet bungalow is still essentially a bungalow because it matches the criteria that comprise a bungalow-style home.   

However, people may say that they are really one and a half storeys and not bungalows. They are referred to in British a “chalet bungalows” or “dormer bungalows” 

History of the bungalow –  

The term ‘bungalow’ originated in the Bengali region of India, meaning ‘house in the Bengal style’. These houses were traditionally small, of one storey and detached, and had a wide veranda. The bungalows were built in India for English sailors of the East Indian company. The bungalow became known in Britain, and then America, where it had high status. 

Later in the 1960s, the form evolved into a chalet bungalow with bedrooms in the roof space, with dormers.  

Things you need to bear in mind before you convert –  

Before you start converting your bungalow there are a few things you should consider. Firstly, you need to make sure that you have enough room to install a staircase to access the floor above.   

Another thing to consider is that when converting a property into a chalet, it’s essential that there is plumbing on the new floor. This is so you will be able to have heating and water if you are creating a bathroom.  

How much does it cost to build a chalet/ dormer bungalow in the UK?  

As dormer conversions are relatively straightforward to add to a home, they are the cheaper type of conversion. They would typically cost around £31,000 – £58,000 depending on the size of the conversion and other factors. 

How long do they take to build?  

Most dormer/ chalet extensions can be completed within as little as 6 – 8 weeks. Although, you should keep in mind that the design and planning process can take longer than the build itself.

The Ultimate Beginners Guide To Ground Floor Flat Extensions

Improving your home is becoming very popular among homeowners who are looking for more space. This is because with property prices increasing, it is becoming more expensive to move houses. If you own a ground floor flat it can be greatly improved by a bit of construction work.  

Ownership of the flat –  

Firstly, if you are a leaseholder and want to commence works on the property, you must get freeholder consent before you can carry out any internal or proposed building extensions.  

The lease plans will tell you whether the demised premises space is occupied under a lease contract. This includes the garden that comes with the flat, or whether you simply have permission to use it. Some leases don’t allow any construction to take place in the garden, so make sure you check.  

Do you need planning permission?  

Before going into the planning process, it’s a good idea to know what you are trying to gain from the proposed space.   

When adding an extension onto a ground floor flat, planning permission is a must. However, with the right architects by your side, this doesn’t have to be stressful. 

To add an extension to your flat you must apply for planning permission. If your flat is a listed building it is likely that you will need listed building consent. You should contact your local planning authority for advice before you start work. 

Adding work to a listed building that affects the historical character without consent is a criminal offense. 

However, if you are using an architect, they will be the best people to guide and advise you through the planning process.  

Planning your design for the flat extension –  

Once your planning is approved it is a good idea to plan and understand exactly what you require to do with the new space. Do you want to extend the kitchen? Open up the living room? Or create another bedroom?  

It is also important to play around with the space and work out the best layout for the extension. A popular element many homeowners like to include is natural daylight. So, to increase the property value and aesthetic of the home you should think about including skylights and bi-folding doors.

Building A Conservatory On A Budget: Ways How To Save Money

If you are looking to add a valuable asset to your home, conservatories are the way to go. However, if you are trying to stay within a budget there are ways you can achieve a well-designed project. Some conservatories can reach up to £75,000 although, there are ways to get one done for as little as £5,000.  

Here are some ways to save money on a conservatory. 

Create a DIY conservatory –  

One of the best ways to save money on creating and installing a conservatory is by doing it yourself. While this is a much cheaper option, the process is complicated and can cause a lot of stress. 

You’ll need to build every element on your own, from the foundation to the roofing. As well as this you will have to make sure your design is within permitted development. Otherwise, you will have to spend more money on planning permission.  

Choose a cheaper type of conservatory –  

 There are a lot of options when it comes to the type and size of the project you want to create. You can decrease the costs by being careful with the size of the new space.  

For example, you could do a flat-roof and squared-off build to reduce the number of materials. However, if you use double glazing and slimline frames it lets the natural light flood in.  

If you design a conservatory with a fully tiled roof and partial brick wall instead of glass, be expected to pay more. Whereas, you can get simple lean-to frames that are not that expensive.  

 Choose uPVC over aluminium  

 UPVC offers a great balance between durability and price. It is a cheaper price than aluminium but it isn’t far off when it comes to performance. UPVC gives you as much flexibility and energy-saving potential. You can ger recyclable uPVC, meaning you can also help the environment while you cut the cost of your conservatory.  

Decide what it’s going to be used for first –  

Make sure you know how you are going to be using the conservatory. So, you don’t payout for any unnecessary features you don’t need.   

You should think about what you will use it for and when you are spending the most time in it. If you only use it on hot days in the summer you might not need as many electrical sockets. And if you use it all year you may consider adding underfloor heating.  

Use energy-efficient double glazing –  

A crucial way of saving money is to make sure you are using energy-saving materials. A way of doing this is by getting double glazing windows which increases the insulation and reduces energy usage.  

Double glazing works to create a thermal barrier for your space, pairing with the frames to give you air and water tightness. Because of this, you can stay comfortable in your space without relying on heating.

Planning A Basement Extension/ Conversion: Here’s What You Should Know

If you are in need of extra space but aren’t in a position to move house or extend outwards or upwards, there is another way. You could consider a basement conversion or an extension.  

What is a basement extension? 

A basement can be a great way to expand your living space by creating an extra bedroom, lounge, office, or gym. Basements are slowly becoming more popular in the UK. As people look for more space and don’t have the ability to extend wider, longer, or higher.  

What is a basement conversion? 

A basement conversion is a process of changing the space into an inhabitable room.  

There are three ways of building a basement extension:  

  • Conversion or refurbishment of the existing one 
  • Adding a basement to an existing property – a good option for when there’s no other way to gain extra space.  
  • Building a new basement as part of a new house build. 

Do basement conversions/ extensions need planning permission?  

You should speak to your local planning authority and building control department before you start any work. To make sure you know what permission is required. 

If you are converting an existing basement and are not making any changes to the external appearance of the building, you are unlikely to need planning permission. Whereas, if you are creating more room or if you are making changes to the external appearance of the property by adding a light well, then you are likely to need planning permission.  

Advantages basements can provide –  

In some parts of the UK especially London, where property values are at a premium, many people are turning to conversions and extensions. Another advantage is that you can create a new floor that can be used in different ways. 

Some more practical advantages are: 

  • Sun tunnels – these use mirrors to reflect sky and light above. 
  • Open up the space – keep the space as open as possible with minimal structures like walls. Consider using glass to enhance the light, for example, a glass staircase.  
  • Rooms with no light – rooms that work well with no light are perfect for basements, for example, entertainment rooms, storage, utility rooms, etc.  

Conversion/ extension disadvantages –  

The major disadvantage of starting a project in your basement can be the cost. However, in areas where property values are high, basements can work financially. Another disadvantage is that the construction of an extension or conversion can be complex, messy, and loud. 

Cost –  

Depending on the type of project you would like to achieve the prices will differ. Converting an existing basement will averagely be around £800 – £1500 per square metre. And if you are lowering the floor level it will cost you between £1400 – £2000 per square metre.  

Architects in London were asked how much it would cost to extend a basement. Most varied between £3000 – £4000 per metre square, for mid-range finishes.

Everything To Know About Extending Buildings Upwards

New permitted development rights that will cover a range of building types that allows them to go upwards and deliver new homes. 

At last, homeowners, developers, and landlords can build upward extensions and add two storeys for housing to their buildings without needing planning permission. This is generally referred to as upwards extension permitted development rights.  

The logic to this type of extension is that there is a severe housing shortage. And the government doesn’t want concrete over green space. So, if you can’t build out, you should build up.  

Can I extend my house upwards?  

If the existing house is two or more storeys high, you can extend your house upwards and add two storeys under new permitted development rights. If the building is only a single storey currently, you can add one more storey under permitted development.  

You can’t add new storeys using the new permitted development rights if the house has had any new storeys added to it since it was built.  

Planning permission –  

Houses built before 1948 cannot be extended upwards without planning permission. However, the easier route to building isn’t open to you. 

 Your property also will not qualify if it’s in a conservation area, an area of outstanding natural beauty or a national park. You also can’t use permitted development on a listed building, so you will need to get planning permission if you fall under any of these categories.   

A short summary –   

  • Firstly, If you live in a terrace, you can only go 3.5 meters above the rest of the terrace. 
  • If you live in a semi-detached house that’s two or more storeys high, you can add two storeys 
  • If you live in a bungalow, you can only add one storey, and for all houses, the roof type must match what you have right now.  

Cost of an upward extension –  

There are a lot of factors that will affect the cost. However, you should be budgeting around £50,000 – £70,000 to build a one-storey extension. Whereas, if you’re building a double-storey the price would be around £80,000 – £100,000.  

Not only does an extension add space to your home, but it also increases the value of the property. Research has shown that an extension can add up to 23% to the value of your property.

Many people are not a fan of dormers because they don’t always look as good on the outside as they do on the inside. But if they are designed well, and by a good architect then they are a great contribution to the roof.  

Some of the different types are:  

  • Gable fronted – The most common type. It has a pitched roof of two sloping planes, supported by an outward face. 
  • Hip roof dormer – It has a roof composed of three sloping planes that rise from each side of the frame. 
  • Flat roof dormer – The roof of this is a single flat plane approximately horizontal.  
  • Shed dormer – This also has a flat plane roof, but it is sloped in the same direction as the principal roof.  
  • Lucarne – A dormer on the slope of a gothic spire, usually slender and gable fronted.

Timber Frame Extensions – The Good And The Bad

A timber frame extension is an economical and impactful way to increase your home’s space and add value to your property. This type of extension is often quicker and easier to build than blockwork projects and it’s great if you’re building on a budget.  

Advantages of timber frame extensions –  

Choosing a timber frame structure will allow for a quick build time, it would be weatherproof and secure much faster than other construction methods. Timber is an environmentally friendly material with excellent insulation. This means that not only will your extension be eco-friendly, it will also be energy efficient.  

Your timber frame extension can be produced in any style. It will blend in with your extension home whether that be wood, render, or brick finish. However, because you are allowed to select any style if you would like you could apply a contrasting finish to really make it stand out.  

Disadvantages –  

The timber used in home designs is all pressure treated with preservatives. However, the risk of rot is greater when it comes to working with wood. But assuming they’re built correctly the risk should be minimal.  

 A timber frame won’t resist sound transmission as a well-built home because the block home has more density to it. Although, you can add insulation or sound-deadening materials to stop sound transmission. 

Often people say they don’t feel solid enough compared to traditional extensions.  

Why timber frame extensions are built quickly –  

Timber frames are usually built off-site in a factory and are designed to fit the exact measurements provided. While the frames are getting constructed the external groundwork takes place. They do two things at once because it is important to get it done before the weather changes.  

Once the frame is built the extension will be watertight, allowing for you to install electrics, plaster, and plumbing sooner.  

Deciding you install a timber frame extension can eliminate a lot of issues such as the noise and the mess from the construction. With this, you can gain an extension without feeling stressed and enjoy your house.  

Depending on the scale and complexity of the job, it usually takes between 6 to 12 weeks to design and build a timber extension. 

Will you need planning permission?  

You will need to check with your local council to see if your proposed extension is under permitted development. And if it is not you will need to seek planning permission. You may find that if you live in a conservation area or an area of natural beauty that you have restrictions on what you can achieve.  

How much does a timber frame extension cost? 

On average in the UK, the cost of planning and constructing a timber-framed extension is around £27,000, which is around £1,400-£2,400 per square meter. Prices can vary depending on the size of the project and also what type of timber you are using.
