Heritage Windows, Doors & Garden Rooms in Stockbridge
Stockbridge is arguably one of the most picturesque towns in Hampshire, with its wide Georgian High Street and the River Test flowing under the pavement. At KJM Group, we provide high-performance triple glazing and secure composite doors designed to respect the unique character of the Test Valley.
Whether you need to replace draughty windows in a Longstock cottage with heritage flush sash, or you want a modern tiled garden room to enjoy the riverside views, we offer the perfect balance of style and substance. Plus, with our No Pressure Promise, you get honest advice and a fair price without the hard sell.
Why Stockbridge Chooses KJM Group
KJM Group has been working in the Test Valley since 1983. We know that Stockbridge is unique. The strict Conservation Area along the High Street, combined with the damp environment of the river valley, means your windows need to be both aesthetically perfect and incredibly durable.
We don't offer a "one size fits all" service. We specialise in Timber Alternative systems that satisfy local planners, providing the charm of wood without the warping or rotting often seen in original riverside properties.

The Look of Timber, The Life of uPVC
For the brick-and-flint cottages of Longstock or the Georgian facades of Stockbridge High Street, maintaining the "flush" sightline is non-negotiable. We install the market-leading Residence Collection (R9) and Deceuninck Flush Sash windows.
These windows are designed from the ground up to replicate 19th-century joinery. They feature mechanical joints (giving the appearance of hand-crafted wood) and come in heritage colours like Agate Grey and English Oak. They are widely accepted in conservation areas because they preserve the character of the building while offering A-rated energy efficiency—essential for keeping old stone cottages warm.
See It In Person: The Roseview 'Ultimate Rose'
Seeing is believing. Many of our Stockbridge clients are initially sceptical about "plastic windows" until they visit our showroom and see the Roseview 'Ultimate Rose' sash window.
This award-winning window is virtually indistinguishable from timber. It features a slim mid-rail, authentic mechanical joinery, and a deep bottom rail that perfectly mimics Victorian craftsmanship. Critically, it features "run-through" sash horns—integral to the frame structure rather than stuck on—which provides a seamless, high-quality finish required for premium properties.
Beyond its appearance, the Ultimate Rose can be specified with acoustic glass to significantly reduce traffic noise from the High Street, ensuring your home is as peaceful as it is beautiful.
Tiled Garden Rooms & Extensions
Stockbridge properties often benefit from stunning river or valley views, but older conservatories can be too cold to enjoy them in winter. We specialise in replacing glass or polycarbonate roofs with Solid Tiled Conservatory Roofs.
A tiled roof creates a true "Garden Room" that feels like a permanent extension. It balances the temperature year-round, removes the glare of the sun, and drastically reduces rain noise. We can install Velux windows to maintain light levels and finish the exterior with tiles that match your existing property.
Planning Permission Made Easy: Changing a glass roof to tiles is classified as a "material change" and usually requires Planning Permission and Building Regulations approval. This deters many installers, but not us. KJM Group handles the entire application process for you, ensuring your new room is fully compliant and stress-free.
Secure, Heritage-Style Doors
A standard uPVC door can ruin the look of a period cottage. That is why we offer a vast range of Composite Doors designed for character properties.
As you can see from the image, we can match a Residence 9 window with a high-security composite door in the same finish. Whether you choose a solid-core design in Chartwell Green, Painswick, or classic Black, you get a cohesive look that enhances your home's kerb appeal. All our doors come with multi-point locking systems as standard, keeping your home secure without compromising its "Test Valley" charm.
Aluminium: Slim, Strong & Modern
While Stockbridge is famous for its history, many homeowners are adding modern extensions to the rear of their properties to create open-plan kitchen diners. For these spaces, Aluminium is the material of choice.
We install premium Aluminium Bi-Fold Doors and slimline windows that maximise the light flooding into your home. The incredible strength of aluminium allows for thinner frames and larger panes of glass, giving you uninterrupted views of your garden or the River Test. Available in contemporary Anthracite Grey or classic Black, they provide a stunning contrast to traditional brickwork.

In most cases, yes. Replacing a translucent glass roof with a solid tiled one is considered a 'material change' to the property's appearance, which typically requires Planning Permission. It also requires Building Regulations approval regarding structural support and insulation. KJM Group manages this entire process for you, dealing with the local authority to ensure full compliance.
You can, but you must be careful with the design. Standard uPVC is often rejected. We install specific heritage ranges (like the Residence Collection) that mimic traditional timber joinery so closely they are frequently approved by conservation officers. We can advise you on what is likely to be accepted for your specific street.
Yes, we cover the entire SO20 postcode area and the wider Test Valley, including Longstock, Chilbolton, Leckford, and the Wallops. We are very familiar with the flint and brick architecture common in these villages.
