- Client: Private homeowner
- Location: Snowbury Road, Fulham, London
- Project Type: Period property refurbishment
Nine Zero was commissioned to manufacture and install bespoke timber sash windows for a period property on Snowbury Road in Fulham, London. The project required a balance between preserving the home’s traditional appearance and improving day-to-day performance, including thermal efficiency, acoustic insulation, and security.
Working closely with the client, our team designed timber sash windows that reflected the original detailing and proportions of the property while incorporating modern glazing and locking systems. The finished installation helped retain the character of the home while improving comfort and reducing external noise in a busy West London location.
Our work with developers
We work with homeowners, developers, architects, and installers across London and the South West, delivering bespoke timber windows and doors for both refurbishment and new-build projects. Every product is manufactured to order, allowing us to meet exact project specifications while maintaining consistent quality and reliable lead times.
For this Fulham project, our team produced custom timber sash windows designed specifically around the existing openings and architectural detailing of the property. This ensured the new installation complemented the original building while meeting modern performance standards.
Scope of work
The project included the manufacture and installation of bespoke timber sash windows designed to replicate the traditional appearance of the existing windows, including fine glazing bars and period detailing suited to the property’s original architecture.
Manufactured from FSC-certified timber, each window was built to precise measurements to ensure an accurate fit within the existing openings. Acoustic glazing was incorporated throughout the installation to help reduce external noise levels, which was an important consideration for the property’s Fulham location.
Alongside improved sound insulation, the windows also delivered improved thermal performance, helping to reduce heat loss and support energy efficiency within the property. Modern locking systems were integrated discreetly into the design to improve security without affecting the traditional appearance of the windows.

What our clients say

Challenges and achievements
One of the main challenges of this project was preserving the character of the property while upgrading performance to modern standards. The new sash windows needed to align with the proportions and detailing of the original design while also improving insulation, security, and acoustic performance.
Achieving this required careful surveying, precise manufacturing, and detailed design work to ensure every element fitted seamlessly within the existing structure. Acoustic glazing also needed to be incorporated without compromising the windows’ classic design elements.
The completed installation successfully delivered a practical upgrade for the property while maintaining the period aesthetic expected of homes in Fulham and the surrounding West London area.
