Did you know that adding an extension to your property can increase its value by up to 23%? Well, doing so with a bungalow is no different, and the work can be carried out at a lower price than a typical three-bedroom house.

That sort of increase in value to a property is difficult to ignore, but how exactly how much does a bungalow extension cost?

Carry on reading, we’ll answer that very question for you.

Your Bungalow Extension Price: A Breakdown

Depending on the size of your bungalow, adding an extension will set you back on average anywhere between £20,000 and £30,000. We understand that £10,000 price difference can be the difference between giving the thumbs up on such a project or going back to the drawing board.

There are an array of factors that impact your overall bungalow extension price, and we will go through all of them in much more detail. Upon reading, hopefully you’ll be better placed to make an informed decision.

Before we delve into those aforementioned factors that can alter a bungalow extension cost, let’s take a look at the varying options available to you.

Types of Bungalow Extension

When committing to a bungalow extension, you are met with four main options. Each have their own benefits, and a lot of it comes down to your budget and design taste.

Dormer Bungalow Extension

A dormer extension is unique in that it is added to the existing roof of the bungalow. In essence, you are creating another half-sized room in your property, which can be perfect for a new bedroom. Lighting isn’t a problem, with a well-fitted skylight giving you as much natural sunlight as you could possibly wish for. An added bonus is that, due to you building upwards on an existing single storey property, it is rare that planning permission is required.

Bungalow Loft Extension

It is a common misconception that a loft extension isn’t possible with a bungalow given its size constraints. In fact, as far as we at Loftera are concerned, it is a criminally underused method of extending a home. Providing that the loft in question is above feet high, it is unlikely that the roof will need to be lifted. As a result, a loft conversion should be very much on the cards. The main plus point here is that opting for this method is cheaper than a full extension.

Single Storey Bungalow Extension

Perhaps the above two options don’t jump out at you because you like living in a single storey property? You do live in a bungalow after all, and there is every chance that you want to keep it that way. If that is the case, a single storey bungalow extension can see work carried out on the side or the rear of your home. On some occasions, the extension can be made to the front of the property, although this isn’t as popular. If you’re looking to add or extend rooms without building upwards, this is the option for you.

Bungalow Roof Extension

A bungalow roof extension tends to involve adding an extra half storey to your property. You now have gone from a one storey bungalow to one and a half storeys, but this is ideal for some homeowners seeking additional living space.

Reasons to Extend Your Bungalow

Now that you know your main options, we move onto a point that is probably already at the forefront of your thinking. You are more than likely well aware of the reasons why extending your bungalow is a solid investment, and that is why you’re reading this article.

Be that as it may, we’re going to explain the benefits for you. Gone are the days of bungalows being for the elderly or those with mobility difficulties. In the 21st century, they have become an increasingly popular investment choice for young homeowners given their potential for further development upon purchasing.

There really aren’t many property options that can increase in value like a bungalow can.

Without question, increasing property value is the main reason that people choose to add an extension to their bungalow.

In addition, doing so allows you to adapt your home to the lifestyle of your choice. Perhaps you are short of space due to starting a family? Or you want to build a home office or gym? Whatever the reason, extending your property is a quicker and more cost-efficient way of doing so without having to move home entirely. Naturally, when building your own extension, the power is in your hands. You can tailor the completed look based on your taste and requirements.

Factors Impacting Your Bungalow Extension Cost

As promised earlier, we’re here to help you decide on where exactly in that £20,000 to £30,000 scale you fall. Of course, there will be examples that cost considerably more, or even much less, but this average acts as a helpful basis to make your key decisions.

Architect Fees

Most property extensions require an architect or structural engineer to draw up the initial plans. Not only can such experts help to bring your vision to life, but they also have the skills and expertise to suggest ways to help you fully utilise your new living space. The majority of architects will charge based on a percentage of the overall costs. This tends to vary between 5% and 12%. Perhaps you would prefer to know their fees before work begins? That is also completely reasonable, and you can find out more about how much an architect costs in our blog.

Labour

Labour fees really do go hand in hand with the amount of work that needs to be done. The longer the job, and the more labourers required, the more it will cost.

Size of Extension

We won’t insult your intelligence with this one. It goes without saying that the bigger the extension, the more the project will cost. Next…

Location

As is the case with most aspects in today’s world, location can play a pivotal role in the overall costs of a project of this size. If you’re based in London, expect to pay considerably more than you would the further north you travel.

Materials

Some materials simply cost more than others, it’s the nature of the beast. A lot of this comes down to personal preference, but you really shouldn’t be compromising on quality.

Groundworks

If you are opting to extend a single storey outwards instead of upwards, as discussed as a potential option earlier, new foundations and groundworks will need to be laid before any other work can begin.

Doors and Windows

You’ll need new doors adding in order to utilise your space and create new rooms. Similarly, adding windows is the ideal way to bring in natural sunlight into your property.

Stairs

If the bungalow life is no longer doing it for you, and you have chosen to build upwards and create a new storey, you’ll want to factor in the cost of a new staircase as well.

Electrics and Plumbing

Have a think in advance about what exactly you are using the room for. Its purpose will have a huge say on the sort of electrics and plumbing that will be required. If it is to be used as a new bathroom or kitchen, it will need entirely different plumbing to a new bedroom or study.

Decorating

This is where the fun really begins. Once the building work has taken place, you get to add your personal touches to the extension. Decorating yourself may take longer, but it will significantly reduce your overall bungalow extension price.

Do I Need Planning Permission For My Bungalow Extension?

The answer to this question is the same for a bungalow as it is for any other property – it is dependent on the location and size. If you are building upwards, it is unlikely that you will require planning permission. Building outwards? That may be a different story depending on how far out you are looking to build. Our advice would always be to check this before work begins. You don’t want to find out the hard (and expensive) way.

How Long Will My Bungalow Extension Take to Complete?

Once again, we advise speaking to the firm that is carrying out the work in regard to this, so that you can plan ahead. On average, a bungalow extension can take between three and four months, some of which may require you to vacate your home. If you family members or close friends nearby, you may wish to ask them about temporary accommodation while the work is being done.

DIY: Yes or No?

If you’re a qualified builder, then yes. Consider yourself as fairly handy with a toolkit but don’t have the necessary qualifications? We would advise against taking on a job of this size yourself. The professionals often hire outside help and still take months to complete. You have to weigh up whether the potential money saved is worth the stress and time taken.

Keep in mind that extensions to all properties must adhere to building regulations. If your work doesn’t satisfy this requirement, you could find yourself in some trouble.

 

Our key takeaway from this article would be to ascertain the type of bungalow extension you are wanting to opt for.

The four main options are:

  • Dormer Bungalow
  • Bungalow Loft Extension
  • Single Storey Bungalow Extension
  • Bungalow Roof Extension

Once you have figured that out, be upfront with the professionals about your budget and requirements, and the rest should take care of itself.
