LSE Grosvenor House Studios

Grosvenor House was already an established student residence. The refurbishment therefore depended on making new installations work alongside selected retained services rather than treating the property as a blank new-build structure.

Existing incoming water infrastructure, distribution pipework and drainage stacks were identified for reuse where suitable. MPH installed new branches and adaptations to suit the accommodation layouts, coordinating connections with the available risers, service voids and plantroom arrangements.

A central element of MPH’s package was pipework serving the basement cold water storage and boosted distribution equipment. The Stage 4 strategy specified a new GRP storage tank and a variable-speed booster arrangement supplying the multi-storey building.

MPH undertook the tank and booster pipework connections, coordinating incoming and outgoing services, valves, supports and access in the plantroom. The booster strategy was designed around duty/assist/standby resilience; equipment selection and controls remained part of the wider engineered system.

Domestic hot and cold water services required the integration of new pipework with retained riser distribution. The specification called for copper water services and new branches to individual studio rooms, while the existing centralised gas-fired hot water infrastructure was to be retained and validated for reuse.

MPH installed the domestic distribution and sanitary connections, routing supplies around the established structure and coordinated fit-out zones. Accessible isolation and practical service positions were important considerations across multiple levels.

The above-ground drainage strategy retained suitable main foul stacks while adding new gravity branches for the revised sanitary arrangements. Cast iron was specified for main soil and discharge stacks, with PVC-U used for horizontal waste branches and connections to appliances.

MPH installed and adapted soil and waste drainage, coordinating pipe gradients, changes in direction and connections to existing stacks. Provision for rodding and maintenance access was essential where routes passed through concealed service zones.

MPH also delivered sanitaryware installation and associated hot and cold water and wastewater connections. The works brought the water supply and drainage networks together at showers, washbasins, WCs and other facilities serving the accommodation.

Final connection positions were coordinated with room layouts, partitions, fittings and architectural finishes so that the completed installations integrated into the refurbished residential environment.

The combination of basement plantroom services, vertical distribution, horizontal branch pipework, above-ground drainage and sanitaryware required close coordination with ASG and the wider refurbishment programme.

The project demonstrates MPH’s ability to deliver a substantial public health package where new services must integrate with retained infrastructure across an occupied-building type of layout and an existing multi-storey structure.
