The Birmingham Post's 'Hidden Spaces' series – which showcases rarely seen aspects of well-known buildings – has inspired a photographic exhibition at New Street Station.

The special feature, which returned for a second year over Christmas, tells the story of the city’s most inspiring and unusual buildings and the people behind them.

Now, the images have gone on display at a special exhibition in the concourse at New Street Station , which runs until September.

The exhibition, featuring Birmingham Post photographs, forms part of a wider Hidden Spaces Unlocked 2015 programme.

It has been organised by Associated Architects and the Royal Institute of British Architects (RIBA) West Midlands and supported by the Heritage Lottery Fund, as part of RIBA Love Architecture Festival 2015.

The show also celebrates the 160-year history of New Street Station which reopens fully in September.

Birmingham Post editor Stacey Barnfield said: “Our Hidden Spaces feature is all about celebrating this city’s unique heritage and to show how relevant it remains today.

“So it’s perfect to hold this exhibition at New Street, which has been a vital part of city life for more than a century and has a bright future.”

The New Street Station exhibition follows the success of similar a week-long event held at Curzon Street station in 2014.

Network Rail is also offering a unique opportunity to win a tour of the historic tunnels beneath New Street Station through a social media competition running until June 7.

Birmingham’s Hidden Spaces Unlocked will also feature events throughout the month of June, including free of charge talks, exhibitions and exclusive building tours across the city, giving the public rare access and insight into many of the city’s hidden gems.

The programme culminates with a flagship exhibition at one of Birmingham’s finest historic buildings, the former Birmingham Municipal Bank on Broad Street, between June 20 and 28.

The grade II-listed building, built in 1933, was the head office for the UK’s first municipal bank, established by lord mayor of Birmingham Neville Chamberlain.

The exhibition will also feature video footage by filmmaker Rich Greene, showcasing 24 of Birmingham’s hidden architectural treasures.

Steve Townsend, co-creator of Birmingham’s Hidden Spaces and an architect at Associated Architects, said: “We’re very excited to announce Birmingham’s Hidden Spaces’ busy programme of events for 2015, which has been a long time in the planning and is much anticipated, following the popularity of last year’s event at Curzon Street station.

“It has been a privilege over the last 18 months to visit and document these incredible hidden spaces, most of which are rarely accessible to the public.

“The response to the images we have shared has been extremely positive, with an overwhelming sense of civic pride clearly evident in the city.”

Conor Nolan, RIBA Love Architecture festival organiser, added: “Through the exhibition at New Street Station and the wider programme of Hidden Spaces events, our aim is to reconnect Birmingham’s residents and visitors with the city’s rich heritage and encourage people to shout about the fascinating spaces and tangible links to history that still remain intact the city.”
