Constructed entirely of timber and cloaked in an undulating zinc roof, the £2 million Salvation Army Citadel Corps in Chelmsford provides 900 sq m new accommodation for the mission. The project illustrates our commitment to pioneering modern methods of construction to maximise the potential of sustainable materials. The building is constructed using a cross-laminated timber panel system, which is akin to jumbo plywood and offers all the advantages of reinforced concrete construction without the environmental cost. A rich variety of façade treatments – including a spectacular tower – offers much to pasers-by and lifts and otherwise drab neighbourhood.
