Over 60 feet in height, this emergency escape staircase serves a central London penthouse. Craned installation was impractical, so we installed an electric hoist to lift the 3 metre cage panels one by one, around the first installed centre column. This allowed the Demax installation team to safely install the treads and hand rail before progressing to the next section. The principle of construction offers effective economical security.
The entire installation from start to finish lasted just five days, which given it was in segments is rather impressive.
