Behind the Scenes: Crafting Bespoke Timber Windows and French Doors for a Central London Apartment
At The Sash Window Workshop, there’s nothing we enjoy more than seeing a project take shape from the very first stages in our joinery workshop through to installation. Replacement timber windows are a key part of this exciting Central London apartment project, where our team is crafting bespoke French doors and sash windows that will transform a beautiful first-floor property.
A Large-Scale Bespoke Joinery Project
This particular order includes 7 bespoke French doors, 1 heritage double glazed entrance door set and replacement sash windows fitted into existing frames.
Every product is being carefully handcrafted in our workshop using the finest Accoya timber. Our process combines traditional joinery skills with modern manufacturing techniques to ensure precision, quality and long-term performance.
Replacement Timber Windows for Period Character and Modern Living
Projects like this are all about balance — preserving the charm of a period property while improving comfort and efficiency for modern living.
Across this apartment, existing timber windows and French doors are being replaced in key spaces including the living room, dining area, kitchen and bedrooms. Each new unit has been carefully designed to complement the character of the property while providing the benefits of modern materials and manufacturing techniques.
In the bedrooms, we’re installing replacement sash windows into the existing frames, allowing us to retain original features while upgrading thermal performance. This approach helps to maintain the property’s traditional appearance while improving comfort throughout the year. Modern double glazing and high-quality draught proofing can significantly reduce heat loss, helping to create a warmer and more energy-efficient living environment.
As with all of our bespoke joinery, the new windows and doors are being manufactured to exact specifications, ensuring a perfect fit and finish. Every detail, from the glazing bars and mouldings to the ironmongery and finishes, has been carefully considered to suit the style of the apartment.
The result will be a seamless blend of heritage styling and improved energy efficiency — an increasingly important factor for homeowners in London. By combining traditional craftsmanship with modern performance standards, replacement timber windows and bespoke French doors can enhance both the appearance and functionality of a property while remaining sympathetic to its original character.
Inside the Workshop
Behind every installation is the skill and craftsmanship of our joinery team. Four of the bespoke French door frames are currently in production, and each one is being carefully assembled with attention to detail at every stage, ensuring a high-quality finish that meets both aesthetic and performance requirements.
The manufacturing process begins with the careful selection of premium Accoya timber, chosen for its exceptional durability, stability and longevity. Each component is precision-machined before being handcrafted and assembled by our experienced joiners, combining traditional woodworking techniques with modern manufacturing technology.
Throughout production, the doors and replacement timber windows undergo multiple quality checks to ensure every detail meets our standards. From the accuracy of the joints and glazing rebates to the smooth operation of moving components, every element is carefully inspected before progressing to the next stage of manufacture.
Particular attention is also given to the finer details that help define the character of the finished products, including mouldings, glazing bar profiles and ironmongery preparation. This ensures the new windows and doors will complement the apartment’s period features while providing the benefits of modern performance.
It’s this combination of traditional craftsmanship, premium materials and modern precision that allows us to consistently deliver bespoke replacement timber windows and doors to a high standard. By manufacturing each product to order in our Berkshire workshop, we can ensure every project is tailored to the property and the homeowner’s individual requirements
Looking Ahead
Once installed, this project will completely transform the apartment, enhancing energy efficiency, durability, longevity and overall aesthetics, whilst balancing between period character and modern performance. We’re looking forward to seeing the finished result!
