There are many ways to improve your house’s square footage and appearance.
Dormer additions are extremely common across the United Kingdom.
Without noticing, you might pass dozens of them each day. This is because it can fit effortlessly into the aesthetic of your home.
In this blog, we’ve explained what a dormer addition is, how much it costs, and the advantages and drawbacks of getting one.
What is a dormer addition?
A dormer addition is a type of extension on the roof of a property. It is commonly done with sloped roofs and can be added to the front, back or side of a building.
Dormer additions usually include a window and are found at the very top of a house.
Almost all types of properties in the UK can get one. But you will typically need a sloped roof.
Dormer addition vs loft conversion
The main differences between dormer additions and loft conversions is that dormer additions both add space and change the roof’s structure.
By contrast, loft conversions simply adapt to the existing space available. This means that loft conversions are generally less expensive than dormer additions.
Why do people get a dormer addition?
There are several advantages to installing a dormer addition in your house.
Space
Firstly, as mentioned above, it gives you extra space.
You’ll be able to use your extended room however you wish. This might give you more storage space or living space.
Light
Your room with the dormer addition will get more natural light. This is especially important in lofts and attics, which are quite dark and damp.
Ventilation
If the window can be opened, you can improve ventilation in the room. This makes it easier to manage mould or damp.
Adds value to property
Properties with a dormer addition tend to be more valuable. Your square footage will go out which is attractive to buyers.
And when done well, it can complement the appearance of your house.
Energy efficiency
Dormer additions often improve the energy efficiency of your house. It depends on the type of window and loft insulation you have.
You can keep the room warm during the winter and lower your energy bills. The extra natural lighting will also reduce your reliance on artificial lighting.
How much does a dormer addition cost?
Like most extension costs, it depends on the size of your house and the professional you use.
According to one source, a dormer loft conversion’s average cost is £45,000. Another expert in the industry indicates it can range from £32,000 to £60,000.
Cost factors
Most professionals charge by the square footage you want to add on.
For small properties where only a small installation is needed, the price might fall below £30,000.
Do your research
You should gather several independent quotations from experts in your area. Ask them how they have reached that price and check their reviews and previous work.
The more experts you speak to and research you do, the better a decision you can make.
How long does a dormer addition take to install?
Most sources suggest that it takes at least six weeks for a dormer addition. This can stretch up to 12 weeks for the most complicated installations.
Potential drawbacks of a dormer addition
Upfront costs
Dormer additions require a significant up-front cost. You won’t receive a return on investment for this until you sell the house.
So, if you don’t plan to sell anytime soon, you’ll need to find a way to fund this.
Planning permission
You will sometimes need planning permission to install a dormer addition. Applying for this can be a time-consuming and stressful process and you are not guaranteed to be granted it.
There may be costs involved as well, especially if you bring in the support of a legal expert.
Risk of poor aesthetics
A dormer addition will change your property’s appearance. When done correctly, it can fit in seamlessly and improve the aesthetic of your house.
However, if the job is poorly done, it might not be to everyone’s taste. You should consider what it will look like at the end before you jump into it.
Maintenance
The extra space in your house comes with additional maintenance. For a large dormer addition, it’s more space that you need to dust and clean.
Larger rooms may also need extra heating to keep them warm during the larger months. This can create higher energy bills.
