Because we manage every stage internally, we ensure precision, consistency, and a refined finish on every project.
Over 30 Years of Heritage & Expertise
As a family-run business, we combine traditional craftsmanship with modern performance standards. Over the past three decades, we have worked across London and, as a result, earned the trust of homeowners, architects, and conservation officers working on some of the city’s most distinctive properties.
- Family-run since 1993
- All work completed in-house
- Specialists in listed buildings and conservation areas
Bespoke Timber Windows & Doors
We design, manufacture, and install a wide range of bespoke timber windows and doors tailored to each property. Rather than offering standard products, we create every piece to match your exact requirements. As a result, you receive a solution that enhances both the character and value of your home.
Timber Windows – Sash & Casement
Our timber windows combine traditional design with modern performance. For example, we produce both box sash and casement windows, all made to measure for a precise fit. In addition, we ensure every window meets current energy efficiency and security standards while maintaining elegant, period-accurate detailing.
- Box sash and spiral balance systems
- Casement windows in multiple configurations
- Energy-efficient and secure
Timber Doors – Front, French & Bi-Fold
In addition to windows, we craft high-quality timber doors designed for durability and everyday use. Whether you need a statement entrance or seamless garden access, we build each door to your specification. Furthermore, all doors meet PAS 24 security requirements while offering a premium, long-lasting finish.
- Front entrance doors
- French and bi-fold doors
- PAS 24 security compliant
Fully In-House Service
Unlike many companies, we control every stage of the process. This means we avoid delays, reduce errors, and maintain consistent quality throughout.
- We carry out a measured on-site survey
- Then, we create bespoke designs with full specifications
- Finally, our own team completes the installation
Because we do not rely on subcontractors, we deliver a smooth, detail-focused service from start to finish.
Specialists in Period & Conservation Properties
We regularly work on Grade II listed buildings and properties within conservation areas. Therefore, we understand the importance of preserving original features while meeting modern regulations. By combining experience with careful craftsmanship, we ensure every installation complements the architectural integrity of the property.
Built on Craft, Honesty & Purpose
We base our work on three core principles, which guide every project we complete:
Craft – We manufacture precise timber joinery with refined, durable finishes
Honesty – We provide clear pricing and realistic timelines from the start
Purpose – We design every product to suit the property, not the other way around
