The Photographers’ Gallery in London has announced that it will reopen on 19 May following its delayed £8.9m redevelopment.

The gallery, which first opened in Great Newport Street in 1971, relocated to Ramillies Street in Soho in 2009. It closed for redevelopment in September 2010 hoping to reopen a year later but fundraising for the capital project proved difficult.

The gallery has raised £8.5m to date with £3.6m coming from Arts Council England, £2.4m from the sale of its previous building and £2.5m from foundations, trusts, individuals, corporates and an auction of donated photographs that was held last year.

The Photographers’ gallery will reopen with 30 large-scale images from Canadian photographer Edward Burtynsky’s 10-year study of the manufacture, distribution and use of oil. There will also be work by the New Delhi-based Raqs Media Collective.

O’Donnell + Tuomey is the architect for the Photographers’ Gallery while a new visual identity has been created by design consultancy North.

Meanwhile, the British Museum has secured £10m from the Heritage Lottery Fund (HLF) for its World Conservation and Exhibitions Centre.

The project is now 80% funded with £118m of the £135m total raised. The centre is due to open in spring 2014.

The HLF has also announced a grant of £1.4m for the Porthcurno Telegraph Museum in Penzance, Cornwall, to develop a learning centre.
