maggie's centre - 470sqm glass façade made by seele

In the UK, Maggie’s Centres offer “free practical, emotional and social support for people with cancer”. The 18th of a total of 57 centres for the post-operational psychological care of cancer patients has been added to the existing north wing of St. Bartholomew’s Hospital in the heart of London. Every centre is designed by a renowned architect. The project in which seele was involved is the work of New York architect Steven Holl.

He describes the concept as “a vessel within a vessel within a vessel”. The structure with its branching concrete frame has an inner layer of perforated bamboo and an outer layer of matt white glass, with areas of coloured glass organised in horizontal bands.

  • seele produced and built the 470sqm glass façade. The succession of 90cm wide bands continues over three storeys and terminates at a rooftop terrace. Three different corner radii, 3,600, 2,600 and 1,600mm, help to give the building its soft form. Special mats were incorporated in the cavities of the panes of matt white insulating glass, so-called polychrome insulating glass, to achieve good-quality lighting inside the building.

    The biggest challenge was the different pane formats. Seven different types were used: flat, bent and partly bent panes in a so-called J-form. The panes of glass were first attached to the steel structure temporarily using a toggle system and subsequently permanently fixed with adhesive.

    With a matt white glass façade, the result is an interior flooded with light which is ideal for meetings between people. The interior character of this building will be shaped by coloured light washing the floors and walls, changing by the time of day and season. Definitely a warm atmosphere.
