Studio Dekka is an interdisciplinary design practice specialising in urban and architectural lighting. Founded by Chantelle Stewart and John Harrison in 2009 our aim is to develop sensitive and intelligent night-time environments that unlock new possibilities for the varied and meaningful life of our cities after dark.

Our team is drawn from the disciplines of architecture, the social sciences, interior design, and fine art. These varied perspectives mean we approach each project critically and with a commitment to understanding the range of factors that contribute to the shifting character of a place at night.

Our current work includes the public realm lighting design for the eight central sites of the Thames Tideway Tunnel in central London; a lighting masterplan and phased detailed designs for the mixed-use Ruskin Square development in Croydon; landscape lighting for St Alban’s Cathedral; and a lighting masterplan in support of a historic trails across Plymouth city centre to celebrate the 400th anniversary of the launch of the Mayflower and an exhibition celebrating the art and architecture of Ickworth House in Suffolk.

Recently completed projects include lighting designs for Walthamstow Wetlands in North-East London (RIBA Award Winner 2018, Civic Trust Award Winner 2019); Kings Crescent Estate, Hackney Masterplan and Phase 1-2 (RIBA Award Winner 2018) and Lesnes to Crossness, Thamesmead, South-East London (Landscape Project of the Year, AJ Architecture Awards 2017).
