Buckland Timber Surrey Quays being installed-hero

Transport for London Stations

The rebuilding of Surrey Quays station in London included a second entrance, new ticket gates and lifts. Buckland Timber supplied fire-protected spruce CLT decking for two flat roofs, which were installed in just one weekend. The project was completed in the spring of 2024 and was given an award for Excellence in Quality by Morgan Sindall Infrastructure, the Main Contractor.

 

The Colindale Underground Station upgrade project, also in London, is much larger. It introduces a spacious, new ticket hall formed by glulam arches, with visible bearing structures made of CLT and glulam beams. The canopy stairwell is made of enhanced visual grade spruce CLT, steel and larch glulam structures and was finished in December 2024. The installation of large timber structures had to be done at night-time only. The new ticket hall is under construction and will be opened in the autumn of 2025.

Good cooperation is essential in timber fire protection

Visually attractive wooden structures help replace less sustainable steel and concrete structures. Massive glulam beams can be several meters thick and even 25 m long. They are usually made of spruce or larch.

Both Transport for London projects were designed by AtkinsRéalis, in close cooperation with Buckland Timber. The fire protection of CLT and glulam was done with clear NT DECO flame retardant.

Timber Beneath the City

At Colindale and Surrey Quays stations, Buckland Timber demonstrates how engineered wood can redefine everyday transport spaces. Glulam arches and CLT canopies introduce warmth, light, and a sense of craft into infrastructure traditionally dominated by steel and concrete. Crucially, the timber is fire-protected using Nordtreat treatments, meeting strict safety requirements while allowing the material to remain exposed and expressive. Together, these stations show that sustainability, safety, and architectural quality can coexist — setting a new benchmark for responsible design across the metro network.

“Nordtreat team has been proactive and very helpful, providing us with quick answers. The training Nordtreat provided at our Devon site was important, as flame retardant treatment must be done in a controlled way within the required humidity and temperature limits. We are happy with the new competencies and service provided.”
- Jess Pearce, Engineer and Project Manager of Buckland Timber
