Glazing, what options do I have?

What glazing options do I have?

We have previously discussed the importance of introducing light and air into a home, but we have not previously discussed the more practical side of how you might achieve this. It might seem obvious, by adding additional glazing, but there are many options you can look at depending on your style aspirations, function needed and of course budget. 

Introducing large amounts of glazing can totally transform a room, drawing in natural daylight and offering a wonderful connection to the outside, however there needs to be some practical thought to ensure the glazing works throughout the year.

Here are a few of our favorite options:

London extension bi fold doors

Bi-fold doors

A very popular option when it comes to introducing a glazed wall, especially when connecting a kitchen diner to a garden or terrace. The glazing is made up of individual panels, that concertina to open and can be stacked away to deliver a totally open, frameless space as due to the design there is a lack of threshold, leaving a seamless connection to the outside.  

At Lavender Road One we selected bi-fold doors so the living space can open completely to the garden, offering a seamless connection.

Sliding doors

Possibly one of the most commonly used options for large glazed doors, these offer the ability to introduce an unobstructed view (without any framing or panels), to bring in a maximum level of light. The sliding door design has the space saving advantage of not having any hinged doors that need space to swing open or be storage away, however only half of the panel is able to be opened.

We used sliding doors at Slaithwaite Road, where there was minimal internal space so this option worked the best to achieve the bright and light interior from the client brief.

Grid framed doors

Often referred to as ‘Crittall’ style, in reference to the British company who first produced this style of glazed door and window, the design has recently enjoyed a design renaissance in popularity. The grid framing can introduce a strong, contemporary aesthetic an interior, and is often used for exterior and interior doors.

For the rooftop master bedroom extension at Arlington Avenue Crittall style doors were introduced onto the private terrace, with the strong design echoed in the ensuite shower screen and fittings.  

At the Curzon Street office our designs use a Crittall style grid frame for an internal glazed partition, offering striking interior design whilst allowing light to filter through into the stairway.

When introducing glazing into a roof this can transform a room, bringing daylight deep within the home and offer a unique connection to the sky, without any issues with losing any privacy within the home.

It is possible to have opening roof lights, which offer additional ventilation but the glazed unit is limited in size.  Fixed roof lights can offer a large panel of glazing which can be produced in much larger sizes, such as at Barnsbury Road were the extension is ‘glass topped’ with a roof light measuring over 4m in length.

Roof lanterns

A roof lantern, where the glass structure pops up out of a roof often in a pyramid shape, is designed to channel light into a home better than the flat counterparts and offer a distinctive and striking design to any interior.

For the remodelling and renovation of The Grove, an Edwardian property in London, we replaced the existing roof lantern with a more contemporary design that still fitted within the property.

Oriel window

An oriel window is a structural ‘box’ like window that protrudes out from the main structure of a home, offering the benefit of extending the home out and offering larger, panoramic views. 

In Thirsk Road the oriel window in the kitchen has created a striking feature, now utilised as a window seat with views out into the garden.

Glazed panel

By strategically introduce glazing we can offer framed views, often over a garden, which can have the benefits of drawing light into an interior and changing the ambience, without having to take into account the building regulations around an opening window.

At The Farmhouse we introduced full height panels in the first floor, to frame the views of the surrounding countryside of the South Downs National Park.

We hope this has given you some ideas and a little inspiration on the different ways to introduce glazing into your home. If you have any questions or want to discuss your next project, do please get in touch.
