Catch a festival of world-class design in showrooms and historic venues in Clerkenwell before it ends tomorrow, says Alison Oldham.

A highlight of the final night is a guided tour of the Zaha Hadid Design Gallery in Goswell Road, famous for its “floating” staircase. The displays present objects by Alessi alongside Hadid’s design pieces and architectural models.

The other unusual venues include a Victorian prison, the House of Detention and the majestic Priory Church at the Order of St John. The Farmiloe Building, an impressive Victorian warehouse in St John Street, features lighting.

A new collection by Balineum marks the Hampstead-based company’s debut at Clerkenwell Design Week, now in its sixth year. The name is from the Latin for bathhouse and the company’s speciality is bathroom fittings so most lights are water-friendly.

Innovative furniture studio And Then Design returns for the fourth time with a collection including a version of the intriguing Flora light in rose and almond gold. The flower templates are laser-cut from aluminium sheets, bent by hand then riveted together. The light is a collaboration between the company’s founder, Samuel Wright, and designer Scarlett San Martin. She grew up in West Hampstead and now lives in East London where And Then Design is based.
