Marylebone Station is a grade II listed ‘National Heritage’ building.
This complex project required a solution that would provide access to replace and strengthen the roof’s steel structure, remove asbestos and install additional glazing to improve light and aesthetics, whilst the station remained open and fully functional with commuters.

Services Supplied
In answer to the Client’s brief, PHD provided a bespoke rolling crash deck which could glide along bridging over the platform & tracks on a rail system designed by PHD to clear the trains. Our solution involved fabricating Gallows Brackets which were resin tied into the main external walls with an intermediate Spine Beam on intermediate platforms, bridging the opposite direction to allow Passenger flow, and of course our Platforms to slide.
PHD designed a mobile temporary roofing solution, which could be easily moved along by our night crew, with the progress of the works. This roof was formed in 3 separate segment, which could be separated to cover the requirements of (the Asbestos gang - stripping out and strengthening team and the finish roof cladders).
The Segmented roof saved equipment, erection time and precious site space. Erected at one end and slid along the roof length to the front of the station where it was craned off over a weekend night.
Mobile Cassette
This solution was vastly more effective than covering the whole area in scaffold or using a traditional erect and strike technique. This bespoke solution reduced project timeframe by 6 months. PHD’s installation at Marylebone Station remains the largest mobile cassette span in Europe.
