Your home deserves
more than a listing.

We launch properties like campaigns—combining cinematic storytelling, social reach and serious estate agency expertise.

AS FEATURED INThe TimesRead the feature ↗

The way people buy homes has changed. Estate agency should too.

Buyers scroll before they search. They care about lifestyle, not just layout. They want to feel something—not simply view something.

KnokKnok pairs the standards of a private office with the creativity of a campaign studio, led personally by founder Mark Breffit.

People don’t fall in love with a floorplan.

Every KnokKnok campaign is designed for the way buyers actually discover homes now: cinematic film, short-form social, founder-led tours and a story worth sharing.

London is where the property sits.
The audience could be anywhere.

Portals wait for buyers to search. We place your home where attention already exists—through film, social distribution, sharing and a London-connected global network.

Mark Breffit, founder of KnokKnok Real EstateFounder-led. Always.

Thirteen years inside the industry. One clear idea for changing it.

After working for Knight Frank and Hamptons Private Office—selling everything from family homes in South West London to a near-£70m trophy property—Mark Breffit decided to build the agency he felt the market was missing.

“We won’t just list. We’ll launch your home like it’s a brand.”

Selling our flat from overseas felt incredibly daunting, but Mark made the entire process as smooth and stress-free as possible. Communication was exceptional throughout.
