Creekside Union Wharf

Value engineering specifies modular construction approach for PRS blocks

This project was the first modular Build-to-Rent scheme in London, and at 23 storeys, it ranked among the tallest residential buildings in the UK utilising modular construction methods at that time.

The development is located on a former wharf adjacent to Deptford Creek in Greenwich, London. Initially, the buildings were designed with post-tensioned flat slabs; however, during our value engineering process, we determined that a modular system would be more advantageous.

To maintain open-plan ground and basement levels, we implemented concrete frames for the lower levels, incorporating transfer slabs at the first-floor levels.

The buildings are stabilised by large concrete cores that also serve as corridor walls. Standardised modules are anchored to these cores. We worked closely with the module supplier to ensure that all differential movements could be accommodated at the concrete and modular interfaces.

Additionally, the creek is utilised to discharge stormwater from the site. We designed improvement works for the river wall to enhance flood defences and incorporate intertidal terraces.
