One of the key charms of this year's Serpentine pavilion, designed by lvaro Siza and Eduardo Souto de Moura, is the way the lights come on one by one as daylight fades. This is an effect that will become more evident as the summer progresses and dusk comes earlier. The lights have been specially designed by Solar Century, using its Streetsmart controller. Batteries store solar energy, and the lights then come on automatically for five hours. The fittings double as ventilation extracts and, in addition to the energy saving, there is the enormous benefit of having no wiring.
Furniture in the pavilion was designed by the architects, and echoes, though not exactly, the structural materials - Kerto laminated veneer lumber from Finnforest and polycarbonate glazing.
The effect is of elegant lightness. This is one-off furniture that we may well see again.
