The Marriott Portsmouth hotel requires updating and a substantial overhaul of the entire building, with the intention of revitalising its appearance and improving its thermal and acoustic performance externally and providing a full internal refurbishment. This will be achieved through the recladding of the hotel’s bedroom tower on all sides. The tower will feature high quality materials chosen to enliven the building making it a distinctive beacon on the main route into Portsmouth. Folded aluminium-composite cassette panels were chosen to enliven the utilitarian building through both colour and shifting light and shade. This is intended to vary appearance both on approach and when traveling past on large adjacent roads. The entrance canopy will be stripped back to slender carefully lit frames.
