P McVey Building Systems delivered temporary modular commercial buildings for Belfast Harbour. The project involved installing 10 advanced CTX modular units, creating newly designed male and female washrooms to meet the facility’s operational needs. Each unit featured modern sanitary fixtures, including touchless faucets, water-saving toilets, and energy-efficient hand dryers. As a result, the design ensured both hygiene and sustainability. During the design phase, the team focused on delivering temporary modular commercial buildings with a modern, high-quality aesthetic. They combined natural and artificial lighting to enhance the interior atmosphere. Additionally, the mechanical and electrical (M&E) systems incorporated energy-efficient technologies, such as a heat pump and hot water tank, to reduce environmental impact. The fire strategy and acoustic design were carefully planned to ensure compliance with building regulations and provide a safe, comfortable environment for users.
