The Hafan Y Coed Adult Mental Health Unit (AMHU) Llandough is an exemplar modern mental health facility suited to the treatment needs of the 21st Century.

The new AMHU centre houses 135 beds over 10 wards along with private recreation space and other facilities spread over 20,000m² of new floor area. The project also included a large £12m car park facility which created an additional 150 car parking spaces over four floors. The entire project was undertaken directly opposite and in close proximity to a working live hospital with the upmost attention given to minimising disruption to patients, visitors and staff.

The project was delivered using fully integrated building information modelling level 2 (BIM) with a huge emphasise on early integration of the whole design team with client and key stakeholders, which brought about better cost certainty, programme efficiency, high standards of health and safety and high environmental performance

A critical part of the delivery strategy was the adoption of innovative modern methods of construction (MMC) to drive efficiency of build. The MMC consisted of a prefabricated precast panel system for both floors and walls delivered to site and erected to form the building envelope and internal floors. This innovative form of construction brought about a large 30% time saving on programme and meant 70% of the building could be manufactured off-site, reducing site labour by 60%. The car park was cut into a challenging steep embankment which required a large permacrib retaining wall to be constructed.

This project achieved a BREEAM excellent rating.
