I want to ask Ms Phelan or Mr. Butler about taller buildings and the use of timber frames. They said there needs to be a competent designer and something like a sprinkler system or other measures to address fire safety issues. Could they expand on what other measures they have looked at? As Mr. O'Connor said, sprinkler systems are quite expensive and would, therefore, create affordability issues. Have the witnesses looked at whether they would always be necessary? Has this not really arisen yet because we have not had these sorts of taller timber-framed buildings going through the planning process? That question is for Ms Phelan or Mr. Butler.
