Mark Breffit.

Thirteen years inside estate agency. One clear idea for changing it.
Mark Breffit, founder of KnokKnok Real Estate

Private-office standards. Campaign-studio thinking.

Mark has worked across South West London and Prime Central London, including roles with Knight Frank and Hamptons Private Office. His experience spans family homes, buying advice and landmark London property.

He founded KnokKnok to make property marketing more watchable, more human and more effective—without losing the judgement, discretion and negotiation that serious estate agency requires.
