Mosaic Place, Purley, London

Mosaic Place is a residential development comprising 106no. mixed tenure apartments in Purley, in the London Borough of Croydon. Appointed to develop and the deliver the proposal the first task was to undertake a holistic review of the extant design. In order to comply with London housing standards and building regulation requirements which had advanced since planning permission was first received, as well as to facilitate the proposed construction methodologies a replanning exercise was undertaken to meet these criteria and also to simplify the design from a construction perspective.

The building consists of four blocks wrapped around an internal courtyard on a relatively steeply inclined site. It has been designed to enable the use of off-site construction techniques including the use of precast concrete wall panels, floor slabs, framing and stair and lift cores. Additionally, bathroom and utility cupboards will be built off site and delivered as finished pods.

Due to sequencing around the assembly of the precast elements and access for requirements for fully assembled bathroom pods considerable attention to detail has been given to construction tolerances, matters around logistics and weathering. As the pods must be installed prior to the floor slab above it is vital that the installed concrete and structural screed meet the challenging criteria around surface levelness and finish. Considerable research was undertaken on products and admixtures necessary to achieve this.

Whilst the external walls are delivered as prefabricated panels bespoke details were developed with a window manufacturer to allow these to be pre-glazed prior to on-site finishing of the outer brickwork leaf and to allow for early weather tightness of the units.

The project commenced on site in February 2021.
