ABOUT
Third Knock is a pre-purchase consultancy designed to give buyers clarity and confidence before committing to a property. Rather than assessing a home for what it is, Third Knock reveals what it could become, unlocking its full potential through considered design thinking and strategic insight. Acting as a discreet third point of call between buyer and agent, the service provides a clear and informed understanding of a property's possibilities long before purchase.
Through indicative layout studies, cost guidance, timelines, and a carefully considered overview of the process ahead, Third Knock equips buyers with the knowledge to move forward with certainty. Each appraisal is grounded in experience and shaped by a deep understanding of planning, feasibility , and delivery, ensuring that every opportunity presented is both ambitious and achievable. The result is a confident, informed buyer who is able to make decisions with clarity and step seamlessly into the next stage of their purchase.

“We do not replace the role of architect or designer. Instead, we help buyers see beyond the brochure at the pre-purchase stage, to provide an understanding of a property’s potential, possibilities and risks before they commit, all while giving agents the insight and material to present that opportunity with greater clarity."


EMMA COOK
Founder & Creative Director
With a background in interior architecture, project management, and client management, Emma brings a unique combination of creative vision and strategic thinking to the property world. Her experience spans mixed-use, commercial, and private residential projects across London and wider UK, where she has worked closely with clients, consultants, and stakeholders to shape spaces that are both purposeful and commercially astute.
As both a designer and consultant, Emma has a 100% project success rate for planning applications in London and can almost immediately inform a client what will and will not be accepted by local councils. For a buyer, having this knowledge prior to even purchasing the property, changes the game entirely, and Emma has worked with numerous Prime-London selling agents and private clients to do exactly this.
Through Third Knock, Emma works with buyers, sellers, and developers to reframe how properties are seen. She combines spatial awareness, market sensitivity and a highly intuitive understanding of people's needs to unlock opportunities that others might miss.
CHARLES FORSDICK
Commercial Manager
Coming from a quantity surveying background, Charles brings a commercially driven perspective to the Third Knock team. Having worked across Prime London residential properties and alongside leading developers, he has developed a strong understanding of cost management, procurement, and the financial realities of delivering high-quality projects. His experience spans both private and large-scale developments, giving him a well-rounded view of how design, ambition, and budget can be successfully aligned.
At Third Knock, Charles ensures that every opportunity is grounded in financial viability. With a sharp eye for detail and a natural enthusiasm for profitable development, he works closely alongside the design vision to assess costs, identify efficiencies, and provide clarity on what is achievable. His input allows clients to move forward with confidence, knowing their project is not only creatively considered, but commercially sound.
