Dormer Window Cost UK | Prices & Cost of Extensions

The cost of a dormer window can vary depending on its dimensions, the materials that are utilised, and the amount of labour that is required. The majority of the time, the cost of installing a gable window will range anywhere from £2,500 to £20,000 or even higher. Several factors influence the cost, including the complexity of the roof, the kind of dormer (shed, gable, hip, etc.), and the cost of work in the area. To obtain a more precise estimate for your project, it is recommended that you compare the prices offered by multiple contractors.

Window installation options with dormers are becoming more and more popular among people who want to make their homes look better and be more useful. An added dormer window can give your home more style and personality, as well as extra air and floor space that can be used.

You can also use it to turn a small attic into a full-height room, which works pretty well. Because of rising housing costs and the trouble and cost of moving, more and more people are deciding to change their lofts to make their current homes bigger and more comfortable.

By adding a dormer window, homeowners can create a space that not only feels more spacious and inviting but also adds a touch of style and character to their property. This additional headroom and floor space can transform a previously underutilised area into a fully functional and aesthetically pleasing room, offering more flexibility in interior design choices and improving the overall living experience within the home.

We will discuss how much it costs to add a dormer window during Home Renovation. So, take a moment and read the following details.

What Is A Dormer Window?

A vertical window with a roof that sticks up from the slope of a pitched roof is referred to as a dormer. Because it provides views to the outside just like a “regular” window and increases the feeling of space, it significantly improves over a skylight.

Dormer designs come in a wide variety and are typically referred to by the sort of roof they have.

Different Variations Of Dormer Windows

Here are some different types of dormer windows that people usually pick according to their choices and preferences. Such as 

• Flat roof dormer – One of the most common dormer windows in the UK, the straightforward flat roof dormer is among the easiest to construct and frequently adds the most interior space.

• Shed Dormer – A shed dormer has a single-planed roof that slopes downhill at a shallower angle than the main roof, similar to a flat roof dormer.

• Gable Dormer – The gable dormer, also known as a gable-fronted or dog-house dormer, has a straightforward pitched roof. It’s a common option for historic homes because it’s typically considered a more conventional and appealing alternative to the flat-roofed dormer.

• Hipped Dormer – As with a full-sized hipped roof, where they are typically erected as a complementing feature, a hipped or hip roof dormer has three sloping planes.

• Eyebrow Dormer – The roof covering of an eyebrow or eyelid dormer curves up and over a low, broad window instead of having sides, making it unusual. This traditional design was first used on thatched cottage roofs in the Middle Ages and looks lovely on the right home.

Dormer Window Cost?

Considering your attic or dormer loft conversion? A small, dark space can be brightened and made to appear larger by adding a dormer window. Dormer window installation often costs between £650 and £1,250 per window. The cost varies according to the dormer window’s dimensions, style, and material. Also, some factors can affect the cost of your renovation plan, such as

• Type of dormer window. 
• Quality and material. 
• The number of windows. 
• Size of the window. 
• Labour charges. 
• Other additional expenses. 

Simple Budget

There are many inexpensive options to install a dormer in your loft to open it up and provide more floor space. In addition, smaller dormers are typically less expensive than larger ones, and employing inexpensive materials will lower the cost. 

A dormer at the back of the house typically doesn’t require planning clearance, saving you time and money. A straightforward flat roof dormer at the back of the house, which can be built for about £5,000 more than the price of a typical loft conversion, can convert an unused attic into a new bedroom or office.

Mid-Range Budget

If you have a little extra money to spend, you can add dormer windows that can improve your home’s overall design. Your property can be unique by adding period-style dormers to cottages, barns, Victorian, Georgian, or modern house styles. 

More expensive materials might be required to match the original construction, and if built at the front of the house, you’ll also need planning approval. However, your home’s symmetry will be preserved, and a pair of matching gable dormers will create a stunning architectural element. They can be matched by your designer to the building’s current architectural design and finishes.

High-End Budget

When money is no object, customised dormer windows can enhance your house as part of a loft conversion or elsewhere with an outstanding feature. For example, a huge Nantucket dormer or an eyebrow dormer could be placed above a full-height corridor, depending on the design and era of your home. Then, when you welcome guests into your home, this will boost the light and sense of space and create a wonderful first impression.

DIY vs. Professional Installation

When it comes to home improvements, one of the critical decisions homeowners must make is whether to take on a project as a DIY endeavour or hire professionals for installation. This decision often hinges on factors such as cost, project complexity, time investment, and the homeowner’s skill level. Let’s explore the advantages and disadvantages of both DIY and professional installation to help you make an informed choice.

DIY Installation

Advantages:

Cost Savings: Generally, the most compelling argument for DIY is the potential savings. By eliminating labour costs, you can significantly reduce the total expense of a project.
Learning Opportunity: Tackling a project yourself can be a great way to acquire new skills and knowledge. It can be incredibly satisfying to learn how to make home improvements.
Flexibility: DIY projects can be done on your own time and schedule without having to coordinate with a contractor’s availability.
Control: Handling a project yourself provides complete control over every aspect, from the materials chosen to the final execution.

Disadvantages:

Time-consuming: DIY projects can take much longer to complete, especially if you’re learning as you go.
Potential for Mistakes: Without professional experience, you might make errors that could be costly or time-consuming to fix, and you might end up needing a professional to correct them anyway.
Tool and Equipment Expenses: Depending on the project, you might need to purchase or rent specific tools, which can offset some of the cost savings.
Stress: Managing a project, especially a complex one, can be stressful and overwhelming.

Professional Installation

Advantages:

Expertise and Experience: Professionals bring a wealth of experience, ensuring that the job is done efficiently and correctly. They can often spot and address potential problems before they become serious issues.
Time-Saving: Hiring a professional can significantly speed up the completion of a project. They have the necessary tools and team to finish the job swiftly.
Guarantees and Warranties: Many professionals offer guarantees or warranties on their work, providing peace of mind that the job is protected in the event of future issues.
Access to Professional Tools and Materials: Professionals have access to high-quality tools and materials, some of which may not be available to the average DIYer.

Disadvantages:

Cost: The most significant drawback of hiring a professional is the cost. Labour can add a substantial amount to your project’s total expense.
Less Personal Involvement: While some see this as an advantage, others might feel disconnected from the process and outcome of the project.
Scheduling: You’ll need to work around the professional’s schedule, which might mean waiting longer than you’d like to get the project started or completed.
Making the Decision
The choice between DIY and professional installation depends on several factors. If the project is small and within the realm of your skills, DIY might be a rewarding and cost-effective approach. For complex, time-sensitive, or high-stakes projects, hiring a professional is likely the safer bet.
