When it comes to preserving the charm, integrity, and value of a heritage property, few details are as important as your windows. Authentic timber framed windows not only define the character of a building but also play a key role in maintaining its architectural accuracy and energy efficiency.
For listed buildings or homes within conservation areas, replacing or restoring old windows requires sensitivity, skill, and a deep understanding of traditional joinery. At Preferred Joinery, we specialise in designing and crafting bespoke timber framed windows for conservation projects across Liverpool and the North West. Our team has decades of experience working with conservation officers, heritage consultants and property owners to create handcrafted timber windows that respect a building’s history while meeting modern standards of performance.
Whether you’re restoring a Victorian terrace, a Georgian townhouse, or a rural farmhouse, we can design and install timber framed windows that perfectly complement your property’s period features and listed status.
Timber framed windows are traditional window units made using high-quality wood, most commonly hardwoods like oak or durable engineered softwoods. They consist of a timber frame that holds the glass and hardware in place, often featuring intricate joinery, mouldings and finishes that reflect the period in which the property was built.
Before the introduction of modern materials such as aluminium and uPVC, timber was the standard choice for window construction, valued for its natural insulation, strength and versatility. Many historic homes in Liverpool and the wider UK still feature their original timber framed windows, which can be restored or replicated to maintain authenticity.
At Preferred Joinery, our windows are entirely bespoke and handcrafted, meaning each one is made to measure for your specific property. We replicate original designs where required, whether that’s Georgian sash windows, Edwardian casements, or Victorian bay windows, ensuring every detail matches the architectural era of your home.
Our timber framed windows can be designed in several traditional and heritage styles, including:
When working on a listed building or a property in a conservation area, maintaining the correct visual and architectural details is essential. Timber framed windows provide the most authentic look possible, matching the proportions, glazing bars, and mouldings of the originals.
Modern manufacturing techniques, combined with high-quality timbers and specialist finishes, mean that today’s bespoke timber framed windows can last for decades with proper care. At Preferred Joinery, all timber is treated and sealed to withstand the British climate, ensuring stability and resistance to rot and warping.
Timber is a natural insulator. Our timber framed windows are designed to meet modern thermal standards, often incorporating double glazing and draught-proofing where permitted. This helps reduce heat loss and lower energy bills without compromising on heritage style.
Timber is one of the most sustainable building materials available. All our timber is responsibly sourced from certified forests, making it an environmentally friendly choice for conservation projects. Unlike uPVC, timber can be repaired, repainted, and refinished, extending its lifespan for generations.
Because every window we produce is made to order, we can replicate original details, match period mouldings, or create custom profiles to suit your building’s needs. Whether your property features ornate sash horns, fine glazing bars, or hand-carved mouldings our craftspeople can recreate every detail with precision.
Well-crafted, genuine timber windows are seen as a premium feature by buyers and heritage specialists alike. Installing bespoke timber framed windows can enhance your home’s kerb appeal, energy efficiency rating and long-term value.
Working on a listed building or property in a conservation area involves more than choosing a style you like. There are important factors to consider to ensure compliance with regulations and to preserve your home’s authenticity.
If your property is listed, you’ll need consent before replacing or altering its windows. At Preferred Joinery, we have extensive experience working with local planning authorities and conservation officers, ensuring that all designs meet the relevant heritage requirements.
We can provide detailed drawings, specifications, and material samples to support your planning application and help the process run smoothly.
Conservation officers often require that new windows match the originals in material, design, and appearance. We can take detailed measurements and photographs of your existing frames to replicate them exactly, including moulding profiles, horn shapes, glazing bars, and joints.
While single glazing may be required for certain listed buildings, many conservation areas now allow slimline double glazing that replicates the look of traditional glass while improving energy efficiency. Our team can advise on the best glazing options to balance performance with authenticity.
Our bespoke timber framed windows can incorporate discreet modern upgrades such as secure locks, draught-proofing and trickle vents, ensuring your home remains comfortable and safe without compromising its historical integrity.
We use advanced microporous paint systems and breathable finishes to protect your timber while allowing it to naturally expand and contract with the seasons. Regular care – cleaning, repainting, or refinishing every few years, will ensure your windows last for decades.
At Preferred Joinery, conservation joinery is one of our specialisms. We’ve worked on countless heritage and listed properties across Liverpool and the wider North West, including Georgian terraces, Victorian villas, and Grade II listed farmhouses.

From there, we design custom timber framed windows that replicate your property’s original character while integrating subtle modern performance enhancements where appropriate.
All our timber framed windows are handmade using time-honoured joinery techniques such as mortise and tenon joints for strength and authenticity. We combine these with modern innovations such as precision machining, sustainable finishes, and energy-efficient glazing to ensure the very best results.
