The development started in June 2021
A leisure centre which is being built in Braddan is due to be completed in August.
Construction got under way in June 2021 and was originally scheduled to complete in December 2022.
However Braddan Commissioners say problems sourcing materials and the increase in prices have kept it from being completed on time.
The development will have a café, nursery, sports hall, pharmacy and a 500m long exercise path around the perimeter of the site.
It was budgeted to cost £6.7 million pounds but they hope it will come in under £7.5 million.
Chairman Andrew Jessopp said: "The Roundhouse is a major investment in community and leisure facilities on the Island and aims to truly provide something for everyone."
