Introducing the Sashment.

At first glance, it looks and operates like a traditional timber sash window. Both sashes slide vertically, just as you would expect.

But there’s a difference.

Once the sashes are closed, the complete window can also open inwards like a casement window.

This can be particularly useful where a window is required to provide emergency escape under Building Regulations, but the clear opening provided by a conventional sliding sash would not be sufficient.

Rather than changing to a standard casement window, the Sashment allows the traditional appearance and everyday operation of a sash window to be retained, while the additional inward-opening function can provide a much larger clear opening.

Two opening functions. One timber window.

Available in a choice of timbers, glazing options, colours and ironmongery.

New windows shouldn’t necessarily look new.

These two timber sash windows have just been installed, but they already look completely at home.

Traditional proportions, slim glazing bars and brass furniture retain the character of the original windows, while modern glazing, improved draught proofing and thermal performance take care of what you can’t see.

Because replacing traditional sash windows shouldn’t mean changing the character of the room.

And that’s exactly how it should be.

Pink probably isn’t the first colour that comes to mind when you think of a traditional Georgian front door.

Yet paired with the warm red brick, painted stone surround and satin brass hardware, it feels completely at home.

This bespoke entrance door was colour matched to Farrow & Ball No. 296 ‘Rangwali’, giving the property a fresh new statement while respecting its Georgian character.

There’s more to this door than the colour.

One detail we’re particularly proud of is the sleeved letterplate. To the best of our knowledge, it’s the only traditional-style sleeved letterplate for timber front doors on the UK market to achieve PAS 24 testing.

That means you don’t have to choose between traditional appearance and modern security. The sleeved design helps protect against letterbox fishing while preserving the classic
Georgian look.

Security is further enhanced with a Winkhaus multi-point locking system and a Yale high-security cylinder, while Q-Lon compression seals help keep out draughts and reduce outside noise.

Every door is also factory-finished using a four-coat Teknos microporous paint system for long-lasting protection, giving the paint excellent durability while allowing the timber to breathe naturally.

A traditional front door should never ask you to compromise. Not on appearance. Not on security. Not on performance.

With the right design and the right specification, you really can have all three.

A front door designed around the home, right down to the glass.

For this beautiful period home, we supplied and installed new Sapele hardwood sash windows alongside a bespoke Sapele hardwood entrance door, finished in a colour match to Farrow & Ball Pigeon No. 25 and complemented by 316 marine grade stainless steel door furniture from .

The defining detail is the door glazing.

Working in collaboration with , we developed a completely individual leaded glass design for our client, bringing together traditional coloured and textured glass within modern, thermally efficient triple-glazed units.

The result allows the character and detail of traditional leaded glass to sit comfortably within a high-performance new timber entrance door - creating something personal to the property rather than simply choosing a design from a catalogue.

From the soft green of the door against the original brickwork to the coloured glass catching the light from inside, every detail feels completely at home.

A wonderful project to have been part of.

It’s often the first thing our customers notice after installation.

Not how the windows look... but how much quieter their home feels.

If you live on a busy road, near a railway or simply want to reduce everyday outside noise, the glazing specification can make a noticeable difference.

Our acoustic double glazing is available with sound reduction from 37dB, upto 40dB while our LandVac vacuum glazing can achieve around 39dB. Combined with high-performance Q-Lon compression seals throughout the window, which help reduce both draughts and noise leakage, the result is a quieter, more comfortable room without changing the traditional appearance of a timber sash window.

You won’t notice the number. You’ll notice that the traffic outside feels less intrusive, conversations are easier and the room simply feels calmer.

Every property is different, so we’ll always recommend the glazing that’s most suitable for your home rather than simply the most expensive option.

Sometimes, the best thing about a new window is what you don’t hear.

The 50-Year Timber Window.

When choosing replacement timber windows, it’s worth looking beyond the initial purchase price and considering long-term value.

Accoya is a modified timber that offers exceptional durability, dimensional stability and a 50-year rot-free guarantee above ground. This means less maintenance, fewer repairs and greater peace of mind for decades to come.

For homeowners planning a long-term investment in their property, Accoya is one of the most advanced timber options available today.

Have you considered Accoya for your next window replacement project?

We love how this one turned out. 🖤

This Venetian sash window is made from Accoya® timber — chosen for its incredible stability and durability — and that sweeping curved head really does make a statement. It pulls natural light deep into the room while keeping everything feeling balanced and elegant.

The dark grey finish gives it a contemporary edge, but the bones are pure traditional joinery. It works just as well on a period property as it does on something more modern, which is kind of the beauty of getting something made to order.

Every window we make is bespoke — dimensions, glazing, colour, finish — all tailored to the property and the people living in it.

If you like the sense of openness that French doors can give, but do not have the width for them, timber casement windows with a flying mullion are well worth considering.

A flying mullion means there is no fixed centre post left behind when both leaves are open. Instead, the central section moves with the opening sash, giving a much clearer opening through the middle. The result is more light, better ventilation, and a stronger connection to the outside.

This can be a particularly useful option for period homes, listed buildings and conservation area properties, where proportions matter and where a bulky alternative may feel out of place.

In simple terms, they offer:
* a cleaner open centre
* a slimmer alternative to French doors
* a more open feel where space is tighter
* traditional character with a practical everyday benefit

For projects where every detail counts, this type of window can make a real difference.

From the factory floor to a Grade II listed cottage.

This is our new 134mm deep box sash window with vacuum glazing - designed for projects where traditional appearance and modern performance both matter.

At just 134mm deep, it has been developed to offer the slim proportions required for period and listed properties, while achieving exceptional thermal performance through vacuum glazing.

We believe it is currently the thinnest, most energy efficient timber sash window available in the U.K. market today.

Made for homes where the details matter - and where the wrong window would stand out for all the wrong reasons.

There is something quietly special about this newly installed Accoya timber bay sash window. The double glazing works discreetly in the background, while the upper lights by feature beautifully recreated leaded glass thermal units that preserve the character of traditional leaded design while meeting the demands of modern energy performance.

Accoya is no ordinary timber. Made from sustainably sourced wood and modified through acetylation (advanced wood treatment), it comes with a 50-year above-ground guarantee and offers exceptional stability - resisting the swelling, shrinking and warping that the British climate so often brings. It holds paint beautifully, offers long-term resistance to rot and insects without the need for preservative treatments, and requires very little maintenance. With repainting typically not needed for around 10 years, it is a material chosen not just for how it looks, but for how well it lasts.
