The Evangelical Alliance has left its home of more than 30 years in Kennington, south-east London, to move to a brand new premises in the heart of the capital's King's Cross redevelopment.
The organisation moved into Whitefield House, Kennington, in 1981. The building was so named because the 18th century evangelist George Whitefield used to engage in open air preaching in the public gardens opposite.
The building has down the years housed the offices of other evangelical organisations, including formerly the Lausanne Committee for World Evangelisation.
The Evangelical Alliance decided it was time to move once again as Whitefield House was "no longer fit for purpose".
"When our neighbours unexpectedly approached us asking if we would consider selling them Whitefield House, we knew this was an opportunity from God," said general director Steve Clifford.
"We spent a lot of time carefully and prayerfully searching for new premises and considering how we can best use them."
Their new base on Copenhagen Street in King's Cross is a contemporary and professional centre that will act as a hub for the UK's evangelicals.
After years of neglect, King's Cross is becoming a highly sought after area thanks to a major regeneration project - one of the largest in Europe.
"Though the mission we have had since 1846 remains the same, we feel that God is calling us to something new and exciting, symbolised in our relocation," says Clifford.
"We are looking forward to so much more in our new building in the heart of bustling King's Cross and are expectant for God to do even greater things as we continue in our mission from a new base that reflects the relevant, 21st century organisation that we aim to be. We hope that you'll join us in this journey."
