Spring River represents a considerable ‘upscaling’ for Marston’s in that it is their largest new build project to date. The Spring River development comprises of a lodge with 104 bedrooms, together with a pub and 7 days a week carvery. They cater for business travellers, families and local residents in this major development. Our challenge was to provide full ‘end to end’ Mechanical and Electrical Design Services to RIBA Stage 4 level. As ever sustainability was the at the heart of this development, most notably the fact that 60% of the hot water base load is provided by the Mitsubishi CAHV, air source heat pump. All work was completed on time and on budget.
