When staff at Genzyme, a US biotechnology company, feel the need to clear their heads, they look for a secluded garden to sit in. They don't have far to go - a few steps along a corridor or down a flight of stairs.
Genzyme's indoor gardens, which decorate the atrium, roof and most of the floors of its headquarters in Massachusetts, are, admittedly, quite small. The largest, a tropical waterfall in the reception, is perhaps 200 sq m; the smallest is about 20 sq m. But what the plots lack in space they make up for in convenience.
