Creekside Union Wharf

Value engineering specifies modular construction approach for PRS blocks

This was the first modular build to rent scheme in London, and at 23 storeys was one of the tallest residential buildings anywhere in the UK to use modular construction methods at the time.

The development is situated on former Wharf adjacent to Deptford Creek in Greenwich, London. The buildings were originally schemed as post-tensioned flat slabs, however during value engineering exercise a modular system was found to be preferable.

The open plan ground and basement levels had to be maintained and so concrete frames have been used for lower levels with transfer slabs at first-floor levels.

The buildings are stabilised by large concrete cores that incorporate the corridor walls. Standardised modules are tied back to the core.

Walsh collaborated closely with the module supplier to ensure all of the differential movements could be accommodated with the concrete and modular interfaces.

The creek itself is used to discharge storm water from the site, while Walsh designed the river wall improvement works to incorporate increase flood defences and inter-tidal terraces.
