About

About nimtim architects.

nimtim architects is a South London practice founded in 2014 by Nimi Attanayake and Tim O’Callaghan. Its architects, landscape and interior designers create distinctive spaces shaped by the people who will live, work, learn and play in them.

The practice develops projects through dialogue and co-creation, using its own briefing game, workshops and engagement events to understand needs and test possibilities. Its residential work explores reuse, colour, natural materials and connections between homes and gardens.
