When it comes to enhancing the architectural appeal of your home, few elements rival the charm of a bay window.

Known for their unique shape, generous glazing, and panoramic views, bay windows have long been favoured by homeowners seeking to add character and functionality to their living spaces.

If you’ve ever found yourself daydreaming about a cosy reading nook bathed in natural light, then a bay window may be the perfect addition to your home.

But before you embark on any renovation project, it’s important to understand the implications and possibilities that come with adding a bay window.

From structural considerations to design choices and local regulations, there are several factors to consider before determining if a bay window is a viable addition to your home.

In this blog, we will delve into the practical aspects of adding a bay window, discussing the technical requirements, cost considerations, and the impact it can have on your home’s value.

Furthermore, we’ll provide you with expert tips and guidance to help you make an informed decision and navigate the process smoothly should you choose to proceed.

The Different Types of Bay Windows

Bay windows is a term used to describe windows which project outwards from a structure, however, there are more specific names for different types of bay windows.

Bow Windows

Bow windows feature a curved design with four or five window sections. They create a softer, rounded look, ideal for Victorian-style homes. Bow windows allow in plenty of natural light, making rooms feel larger.

Oriel Windows

Oriel windows are a type of bay window that does not extend to the ground. They are supported by brackets or corbels, making them ideal for upper floors. You can often see them older period properties, but they can be used effectively in modern designs.

Classic Bay Windows

Classic bay windows have just three openings, offering a more angled look. 

It is possible for bay windows to be installed across multi-stories as well as on different property types, such as detached, semi-detached and terraced houses, as well as flats.

Bay windows can be built from floor to ceiling for a glass wall effect or they can be installed off the ground, otherwise known as an oriel window. In order to install an oriel window, adequate support is required, either through corbels or brackets.

Do You Need Planning Permission for Bay Windows?

In the UK, adding a bay window is often classified as an extension rather than a simple window replacement. This means you may need planning permission from your local council.

However, you may not need permission if:

• The new bay window does not extend beyond the front of your property.
• It does not exceed permitted development rights for your area.
• The window is being added to the rear or side of the house and follows height and projection regulations.

Before proceeding, check with your local planning authority to avoid any compliance issues.

In order to ensure your planning permission is approved, you will want to make sure that your installation will be carried out by a professional. Thankfully, the FENSA (Fenestration Self-Assessment Scheme) website has a database you can search to find a trustworthy installer near you.

They will provide you with a certificate to show that your bay window installations comply with building regulations, are energy efficient and are registered with your local council.

Without a FENSA certificate, you could find issues later down the line when it comes to selling your house, and you may require a solicitor or conveyancer to prove that your windows are compliant- all of which can end up costing you significantly more.

How Much Does It Cost to Add a Bay Window to a House?

The cost of adding a bay window depends on several factors, including size, materials, and labour.

Bay Window Type	Estimated Cost (UK)
Small uPVC Bay Window	£1,500 – £2,500
Medium-Sized Bay Window	£2,500 – £4,500
Large Bay Window	£4,500 – £7,000
Oriel Bay Window	£3,000 – £6,000

How to Style Your Bay Window

Due to the way in which they extend outside the main walls, bay and bow windows create an extra space inside the home which can be used for a number of purposes, such as improving the room aesthetic, creating storage space or a new area for seating. 

Here are some of our favourite bay window styling ideas:

Window Seating

One of the most popular ways people make use of their bay windows is by creating a small seating area or cosy reading space. Some bay windows have a deep window sill which can save you the job and cost of purchasing a seat to fit in the space. All you have to do is find some suitable cushions to stack on top of the sill and your window seat is complete. 

However, for those windows that have floorspace instead of a deep sill, you can find a couch, bench or two armchairs (for bigger windows) to create a seating area yourself. 

Dining Table 

It can be difficult to find the right space for a dining table, particularly if you have limited kitchen space. That’s why we think positioning your dining table and chairs into your bay window space not only looks great, but is practical too, keeping it tucked out of the way and opening up more space elsewhere in the room.

Storage

If you find yourself struggling to find storage spaces in your home, why not transform the space beneath your bay window into a practical storage space? You could have some handy storage units or drawers fitted into the space to store things away neatly. You could even have them made as one large bay window seat with storage space underneath, becoming twice as practical.

Study Zone

The World Green Building Council says workers feel more engaged when they work in natural light. And according to research by Future Workplace, workers in daylight office environments reported a 51% drop in eyestrain, a 63% drop in headaches and a 56% reduction in drowsiness. This is why a bay window can act as a perfect study or work zone. The natural light through the window can boost productivity and focus, allowing you to do your best work.
