Nelson's Journey, the charity dedicated to supporting bereaved children and young people throughout Norfolk, is spreading a very special smile across Norwich encouraging people to donate to the charity's new home, Smiles House.

Across the city centre Nelson's Journey smiles have been imprinted onto the street using 'reverse graffiti' in an unusual bid to boost donations to fund the completion of the their much needed headquarters, Smiles House, in Little Plumstead.

Colin Lang, chief executive of Nelson's Journey, said: 'Earlier this year a nationwide survey claimed Norwich was the 15th happiest city in the UK. Spreading a smile across the city is a positive way we can encourage donations towards Smiles House.

'Smiles House will be a Norfolk home to support Norfolk's bereaved children and young people and will provide a welcoming environment where they can receive support, making us more accessible to the community and people who need us most. It makes sense to start our smile in the city centre and we hope to see it spread far and wide as donations for Smiles House come in.'

Reverse graffiti, which was brought to prominence by street artist Banksy, is created by pressure washing a stencilled area of pavement.

The Smiles House Appeal was launched in November 2012, with a goal of achieving £575,000 in order to relocate the charity into their new home in the Octagon Business Park in Little Plumstead. The total stands at £350,000.

The smiles across the city centre encourage people to text donations to 'SMIL13' followed by the amount you wish to donate to 70070. Readers can also send a cheque made payable to 'Nelson's Journey' to Nelson's Journey, Trafalgar House, Meridian Way, Norwich, NR7 0TA.
