In the new series of Room to Improve, architect Dermot Bannon returns with four new designs for four incredible properties. Charlestown in Mayo, Palmerstown in Dublin, Aughris in Sligo and North Strand in Dublin are the locations for each property. 
This year, we see Claire Irwin return as Quantity Surveyor. With soaring materials costs around the country and budgets being pushed, Claire has to work harder to make sure everyone gets their dream home on budget and on time. To achieve this, Claire will have to keep Dermot on his toes. The first stop for Dermot and Claire is Charlestown in Co. Mayo.
