Work has started to clear brambles and weeds away from the side of Diss Mere, in preparation for a boardwalk to be installed on the tranquil stretch of water.
Members of Diss Youth Group helped to remove the plants from the area behind the council offices, which will become the new Mere Gardens.
As part of the Heritage Triangle Project, a floating island platform and boardwalk will be created with seating and winding paths.
Jess Johnston, arts and heritage outreach manager at Diss Corn Hall, said: 'We would like to say a huge thank you to the young people for all their hard work on Saturday and we're looking forward to running more sessions with the group to develop the garden further.'
The boardwalk is the final part of the ongoing Heritage Triangle Project, which involves new streetscapes and improvements to the Corn Hall.
As part of the £1.6m refurbishment of the hall, a crane has been used to install a new ventilation system at the arts venue, which is due to reopen next year.
Sheila King, heritage triangle project manager, said: 'The crane was lifting Monodraught 'windcatchers' into place on the Corn Hall roof.
'These are special energy- free natural ventilation systems that provide both fresh air and cooling.
'They should ensure a comfortable experience on even the busiest nights in the Corn Hall.
'As each unit weighs 250kg, a special crane with a small footprint was needed to lift them into place.'
The overall cost of the project will be £3.2m.
