Benefits of Glass Box Extensions

There is a range of useful benefits to adding glass box extensions to your existing home. Our team can ensure that each of the glass room extensions we create provides some key upsides, such as:

Benefits of Glass Box Extensions

Each glass box extension we create is able to be adjusted and customised in various ways, such as adding more options for natural light or using glazed extension windows that restrict visibility from outside your home.

Every one of the structural glass units we create can be adapted to suit different roles, whether that means frosting and glazing panels for a private dining space or keeping them clear for a full view of the garden from the dining area.

We construct glass rooms based on the client’s needs. This could include things like improved thermal efficiency through glazed extensions, following modern architecture for a modern home, or even sticking to the architectural style of a period property.

Glass Extension Types

There are various general types of glass box extensions that we can construct, all of which offer some great benefits.

Each glass extension project follows the customer’s needs, but we still start off with a basic glass extension and adapt the design to suit each client’s requirements.

Frameless Glass Extensions

A frameless glass extension is essentially a frameless glass box with only the bare minimum of supports as well as laminated glass beams.

This relies heavily on structural glass but also maximizes incoming natural light, with the laminated glass beams being almost invisible in certain situations.

These completely clear, frameless glass box extensions are perfect for a modern design but can also be good for overhauling traditional buildings.

Making it a triple-glazed addition ensures that the new space remains warm throughout the year, and more glass panes mean more incoming light overall.

Glass Roof Extension

A glass roof extension trades the idea of a glass room for a regular room with glass roofing. This is often a glazed roof window that lets in light from overhead, often alongside larger windows or a glass sliding door that adds good garden visibility.

These extensions allow you to easily add more light to a family home, such as creating a light-filled kitchen/diner area, without having to build an entire glass box extension.

If done well, they can be a way to illuminate any ground floor room as long as the roof itself can be modified.

Glass Lean To Extension

A glass lean-to extension uses an angled roof to provide the same amount of floor space without having to use a rectangular structural glass box, leading to a more compact design overall.

As an alternative to a regular glass box extension, it can be cheaper overall and offer a great garden view.

These lean-to-glass box extensions are ideal for using a similar amount of glass and materials while taking up less space and often having to pay less in general.

These can also be ideal for adding more visibility without having to build an entirely new roof section above the new floor space.

Glass Side Return Extension

Glass side return extensions minimize the amount of materials used, filling in parts of the walls rather than being an entirely new section of flooring.

These essentially replace walls with new windows and doors, making them a non-obtrusive glass extension option for a range of homes.

These small renovation options often have a much lower glass extension cost as a whole and can still be compatible with additions like heated glass.

They also create a good garden view without needing you to build an entire glass box extension, similar to how roof lights can be installed on basically any roof.

What is a Glass Box Extension?

A glass box extension is a structural glass extension made mostly with glass windows, often focusing on a modern design.

These are still made underneath the right building regulations as normal extensions but trade regular walls for glass panels. Using panels means more visibility in exchange for privacy unless the glass itself is frosted.

What is a Glass Box Extension?

This kind of extension is meant to boost visibility and let in natural light, making it a common choice for an extension that goes into a garden space.

However, they can also provide extra floor space overall and offer better visibility of a garden or any other private space that they are facing.

Modern Glass Extensions

Most glass extensions are made with a modern design style, although not all of them.

Like most modern extensions, these can involve a full range of different additions and features, from a pitched roof with roof windows to a seamless connection for frameless glass extensions.

Of course, our team can also focus on keeping the style consistent with the original house.

We are able to construct structural glass box extensions to suit a range of needs, whether that means a double-height extension or something with a specific kind of flush-glazed hinged doors.

Glass Kitchen Extensions

Kitchens and dining areas often get custom extensions of their own due to these areas being regularly used and benefiting a lot from natural light.

While they do not need to be any kind of special design, many homeowners will have extensions placed on these areas because of how high-traffic and central they are to most homes.

FAQs

Do I need foundations for a glass extension?

Not every glass extension needs foundations.

However, if the glass extension needs foundation work, this will have to be considered as part of the overall glass extension costs.

What is the difference between a glass extension and a conservatory?

A glass conservatory is generally a separate room, while a glass extension is usually seamless with the room (or rooms) it is attached to.

If a conservatory was built as part of another room with no wall or door in between, it is effectively a glass extension of that room.

glass extensions FAQ'S

Are glass extensions cheaper than brick extensions?

A glass extension will generally be more expensive than a brick-built one.

However, if you want natural lighting, the cost of a brick extension with a lot of windows might be similar or even higher than just building a glass box extension from scratch.

Certain things may change this. For example, IQ glass glazing and damp proofing may add to the costs, but you may also save more money overall with IQ glass glazing.

Using IQ glass glazing as an example, the higher initial cost of IQ glass glazing may make your extension cheaper in the long term.

Do you need planning permission for a glass box extension?

Like planning permission for regular extensions, a glass extension may require planning permission if it does not fall under permitted development rights.

Permitted development allows you to do certain kinds of work without needing planning permission – we can help you find out if your project qualifies or not.

The specifics behind what does and does not fall under permitted development are hard to judge, but our team can guide you through what it means and whether or not your project plan would need permission.
