It might be an up and down business but a trampoline park is taking a leap forward by expanding its facilities less than a year after opening.

GraVity, on the Riverside Retail Park in Norwich, is spending around £250,000 to build a climbing area and create more seating for visitors.

The centre is aiming to bring in more corporate groups and appeal to adults as well as youngsters.

Business development manager David Metcalf said: 'Children will naturally want to come to a place like this. It is up to us to look at other areas to integrate with to open up different markets.

'Adult exercise is a key market for us. We have fitness classes and you can come as a group for a corporate event.'

GraVity has linked up with Active Norfolk for their Fit for Work programme which aims to encourage office workers to get more exercise and saw employees from more than 10 businesses visit the park.

As well as trampolining, the park offers games such as dodgeball which Mr Metcalf said adds a competitive element to corporate days out.

There are plans to build a mezzanine floor to provide a viewing area for those who do not want to bounce and could be used for functions.

Over weekends GraVity can have up to 2,000 bouncers, often with accompanying adults who need somewhere to sit and pass the time while their little ones jump with more seating part of the plans.

General manager Richard Lang said the expansion was expected to increase their team by about 20% up to around 60 in the next six months.

He said: 'In business you have got to be innovative and diversify and that is what we are trying to do.

'The main thing from our point of view is that we have brought an unused building, which had had complaints in the past, back into business and that is good for the area.

'We have heard that we have added £10,000 to one of the nearby restaurants.'

The GraVity group has received £5m investment which will see it expand its four sites across the country as well as open four new parks around the UK.

The Norwich branch cost £2m to develop, opening in May 2016, and the site had previously been home to nightclub Time.
