Constable Park is currently under construction on the River Stour in Brantham. Owners Ian and Sarah Williams hope to be ready to open for May half term 2021.
Mr Williams decided to invest in the new venture after running Anglia Adventures for more than 20 years and received a rural development grant to help with the build.
Accommodation will feature a luxury lodge sleeping four, three pods in converted steel containers with green roofs, two shower blocks, a toilet block and seven bell tents positioned around a fire pit. The tents will eventually be replaced with timber pods.
The whole site is off-grid, using solar energy, and includes a café and kayak and paddle board hire. Two bookings for weddings have already been taken and local schools plan to bring groups in the summer.
