The experience behind the agency
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 career experience spans family homes, buying advice and sales of properties in excess of £70 million. That is experience from his career before founding KnokKnok, distinct from the agency’s own campaign results.
That range matters. A family moving across South London and a buyer considering a prime London address have different priorities. Both need clear advice, careful positioning and someone who understands what makes a decision happen.
He founded KnokKnok to bring that judgement together with a more watchable, more human approach to property marketing. Film and social reach create attention; local knowledge, discretion and negotiation turn that attention into a serious conversation.

KnokKnok
An independent agency built around personal responsibility, distinctive marketing and a direct relationship between the owner and the broker.
Why I built KnokKnok ↗
The person behind the particulars
Serious about property.
A little less formal.
There is more to a home than its floor plan. The streets around it, the familiar corner and the life beyond the front door all belong in the story.
That is the spirit behind KnokKnok: informed advice, a direct conversation and enough personality to make a home memorable.
Let’s talk about your next chapter ↗Why KnokKnok exists
The experience was there.
The model could be different.
Every property is a campaign, not a listing.
KnokKnok brings together two things Mark believes belong in the same agency: serious property experience and marketing with personality. The presentation should make a home memorable. The advice, qualification and negotiation should give its owner confidence in the next decision.
A home deserves a story beyond its room count. Who is it for? What does living there feel like? What makes the location, layout or character worth a closer look? That is where the campaign starts.
The owner should also know who is responsible. A direct relationship with the broker keeps the reasoning behind the price, the response from buyers and the negotiation close to the person whose home is being sold.
Technology supports that service. Knox helps visitors explore the published guides and listings. Human judgement, property-specific advice and the important conversations stay with Mark.
Explore your home’s campaign potential ↗Working with Mark
A personal approach.
A considered plan.
Give the home a story.
Considered presentation, cinematic film and founder-led storytelling help buyers see more than a set of particulars.
Keep the judgement close.
Attention needs careful follow-through: understanding buyers, weighing feedback and negotiating with your next move in mind.
The work, in practice
A story matters.
