Our People Mirja Mainwaring

Mirja Mainwaring


Mirja joined LSI in 2012, after 8 years with Mbla in Manchester, following her university studies in Germany and Italy. Mirja’s experience has mainly been in the residential sector – initially for private developers and registered social landlords, working as a project architect through all stages of work, and latterly on a £6M conversion of an 11-storey office tower, and £9.5M newbuild scheme for student residences.

With Mbla she worked mostly in the urban context of Greater Manchester – on housing and health centres as project architect – on schemes up to a value of £6M. Since arriving, she has worked on mixed use and residential masterplanning projects, including the winning competition entry for 200 Exemplar housing units for an EcoCommunity, a £5M commercial development in the town centre of Thetford,  and a £13M town centre scheme with mixed residential, leisure and retail uses in Colchester.

Mirja is a design-focused architect, evidenced by the significant inputs she had to the successful planning applications for the 4-storey Thetford mixed-use scheme and the 8-storey, CLT-framed residences’ project at UEA.
