About the Firm
Twenty-five years of representing exceptional homes
Horizon was founded on the belief that a luxury property deserves the same care in its presentation that it received in its construction.
Company Story
Built one relationship at a time
The firm began with a single agent, a small office above a harbour bookshop, and a conviction that the standard listing presentation was not good enough for the homes it was meant to represent.
Twenty-five years later the approach has not changed — only the scale. Every property still receives a bespoke marketing plan, professional architectural photography, and a presentation built specifically for it.
Today the team represents estates, waterfront villas, penthouses, and country properties across six communities, supported by a global referral network for clients arriving from and departing to other markets.
Our Philosophy
Represent fewer properties. Represent them properly.
01
Discretion
Client information, showing schedules, and negotiation details stay inside the firm. Always.
02
Preparation
No property goes to market before it is ready. Preparation is the highest-return work we do.
03
Candour
Pricing advice is given straight, including when it isn't what a seller hopes to hear.
04
Continuity
The advisor you meet is the advisor who runs your transaction from first call to closing.
